Astronomer Software release notes

Subscribe to RSS Feed

This document contains release notes for each version of Astronomer Software.

Version 0.34 is the latest long-term support (LTS) version of Astronomer Software. To upgrade to version 0.34, see Upgrade Astronomer. For more information about Software release channels, see Release and lifecycle policies. To read release notes specifically for the Astro CLI, see Astro CLI release notes.

info

Because Astronomer has separate maintenance life cycles for each minor version of Astronomer Software, the same change can be introduced multiple times across minor versions, resulting in multiple identical release notes. When a new minor version releases, such as version 0.33.0, all changes from previously released versions are included in the new minor version.

If you're upgrading to receive a specific change, ensure the release note for the change appears either:

  • Within your target minor version.
  • In a patch version that was released before the first release of your target minor version. For example, a change in 0.32.5, which released 12/8/2023, is not guaranteed to appear in the 0.33 series, which released 9/8/2023, unless there is a release note for it in an 0.33 patch. However, all changes in 0.32.1, which released June 12, 2023, are guaranteed to be in the 0.33 series, because 0.32.1 was released before 0.33.0.

0.35.0

Release date: July 1, 2024

Use deploy rollbacks to run previous versions of your code

Deploy rollbacks are a new way to ensure that your Deployments can keep running after a broken code deploy or upgrade. When you trigger a rollback to a past deploy, your previous image and/or DAG code are redeployed and start running.

To configure deploy rollbacks, see Deploy rollbacks.

Support for MySQL

You can now configure Astronomer Software to use a MySQL database as the backend for both Houston and your Airflow Deployments. To connect your Astronomer Software installation to a MySQL database, you update the astronomer-bootstrap secret in your cluster to point to your database:

kubectl create secret generic astronomer-bootstrap \
--from-literal connection="jdbc:mysql://host1:33060/mydb" \
--namespace astronomer

Create Teams without using an IdP

Astronomer Teams can now be created without associating the team to an existing identity provider (IdP) group. Use local Teams to efficiently manage permissions for groups that might not exist in your identity provider.

Addiitonal improvements

  • DAG-only deploys are now fully compatible with OpenShift clusters.
  • You can now set a priorityClass to pods created by templates/trust-private-ca-on-all-nodes/containerd-daemonset.yaml. This allows you to set a high priority class for certain pods to force an evication for important processes.

Bug fixes

  • The Astro CLI now shows an error if you attempt to deploy code to a Software installation where astronomer.houston.config.deployments.registry.protectedCustomRegistry.updateRegistry.host is not set.

  • Fixed an issue where Jetstream resources were being created even when global.nats.jetStream.enabled = false in the Software platform configuration.

  • Fixed an issue where the default astroUnitsEnabled value in values.yaml was not respected when creating Deployments via the Houston API, resulting in Deployment creation failing when the resource strategy is not explicitly specified.

  • Fixed an issue where Houston could produce errors if the password for a Postgres database included special characters.

  • Fixed an issue where pagination on specific Software UI screens did not behave as expected.

  • Fixed an issue where the lastUsedAt data for a service account was not updated when the service account deployed an Airflow image.

  • Fixed a bug causing disruption to retrieval of logs for users with External Elasticsearch.

  • Fixed a bug where a blank page is displayed when navigating to the user detail of a user who has been invited to a Workspace, but have not yet accepted an invitation.

  • Fixed an issue where a pod limit was enforced for a custom resource based Deployment with the K8s executor.

  • Fixed a bug where the pgbouncer calculator failed to provision Deployment resources.

  • Resolved an issue where switching from DAG deploy to image deploy caused an error state.

  • Fixed an issue where the Astro Runtime 11.2.0 wouldn't load the webserver when creating a Deployment.

  • Fixed a bug where containerd images failed to load for some cloud providers.

  • Fixed an issue where a patch error occured during an Astro Runtime upgrade when Pod Disruption Budget (PDB) was enabled.

  • Resolved an issue where custom based resource Deployments were converted to AU-based after a platform upgrade.

  • Fixed a bug where the the dag-deploy server pod failed in OpenShift due to an fsGroup error.

  • Fixed a bug that sometimes prevented dagDeployment server and client resources from being configurable.

  • Resolved the following vulnerabilities:

0.34.2

Release date: May 31, 2024

Additional improvements

  • DAG-only deploys are now fully compatible with OpenShift clusters.

  • You can now configure resource usage for the DAG-only deploy server in your values.yaml file like in the following example:

    global:
    dagOnlyDeployment:
    enabled: true
    resources:
    limits:
    cpu: 100m
    memory: 400Mi
    requests:
    cpu: 100m
    memory: 400Mi
  • You can now configure a priorityClass for all Pods created by the Containerd daemonset. This ensures that Pods generated by the daemonset can be reliably spun up on new nodes whenever they're removed from an existing node. To configure this, add the following lines to your values.yaml file and apply the configuration to your platform:

    global:
    privateCaCertsAddToHost:
    enabled: true
    addToContainerd: true
    priorityClassName: <priority-class-name>

Bug fixes

  • Fixed an issue where larger DAG deploys had significant performance issues.

  • Fixed an issue where Deployments using custom resources would be reverted to using AUs when you upgraded the Astronomer Software platform using Helm.

  • Fixed an issue where the default astroUnitsEnabled value in values.yaml was not respected when creating Deployments via the Houston API, resulting in Deployment creation failing when the resource strategy is not explicitly specified.

  • Fixed an issue where using a service account to deploy DAGs without the Astro CLI would result in the service account's lastUsedAt value not updating as expected.

  • Fixed an issue where creating Deployments would fail when using the the airflowStratV2 PGBouncer calculation strategy.

  • Fixed an issue where upgrading within the 0.34 series could disrupt external Elasticsearch configurations.

  • Fixed an issue where tasks on a Deployment could start to fail if the Deployment used a custom resource strategy, used the Kubernetes executor, and attempted to run many tasks at once.

  • Resolved the following vulnerabilities:

0.34.1

Release date: April 8, 2024

Documentation refactor

  • To make the documentation more consistent with Helm standards, all instances of config.yaml have been replaced with values.yaml.

Additional improvements

  • NGinx now has a dedicated service account with only the required permissions for the service

  • You can now specify an image pull secret for the privateCaCertsAddToHost.certCopier image so that it can pull the image from a private registry.

  • Added support for Kubernetes 1.29.

  • You can now define additionalScrapeJobs in the Prometheus Helm chart so that Prometheus scrapes additional jobs on the Astronomer Software cluster. For example, you could add the following configuration to values.yaml to scrape a static job:

    astronomer:
    prometheus:
    additionalScrapeJobs:
    - job_name: example-static-job
    static_configs:
    - targets:
    - localhost:9090

Bug fixes

0.34.0

Release date: February 12, 2024

Updated permissions for upgrading Deployments to unsupported Astro Runtime versions

Breaking change

This update includes a breaking change to the Astronomer Software Helm chart. The setting enableSystemAdminCanUseAllRuntimes no longer exists and has been replaced with:

astronomer:
houston:
config:
deployments:
enableListAllRuntimeVersions: true

This new setting changes whether all Admin-level users can view and upgrade to deprecated versions of Astro Runtime from the Software UI.

By default, any user with an Admin-level role (Deployment Admin, Workspace Admin, System Admin) can now upgrade a Deployment to an unsupported version of Astro Runtime using the Astro CLI and the Houston API.

You can additionally set the following value in your values.yaml file to enable these users to view and upgrade to unsupported Runtime versions through the Software UI:

astronomer:
houston:
config:
deployments:
enableListAllRuntimeVersions: true

Change resource provisioning strategy per Deployment

You can now set a Resource Strategy for each Deployment to fine-tune how Astronomer Software reserves resources for the Deployment within the cluster. The new resource strategies don't use AUs, meaning you can specify the exact CPU/ Memory requests and limits based on the needs of the Deployment. For example, you can configure a Deployment to have significantly more memory than CPU in extra capacity so that memory-intensive tasks are always guaranteed to run. See Customize resource usage for more information.

Deploy only DAGs with astro deploy -—dags

You can now deploy only the DAGs folder of an Astro project to a Deployment. If you only need to deploy DAG code changes, DAG-only deploys are faster and safer than a full image deploy. This also allows you to configure CI/CD pipelines that allow certain team members to only push DAGs, while allowing other team members to push Astro project configuration updates. See Deploy DAGs for more information.

Additional improvements

  • You can now configure a global label that is applied to all Astronomer Software Pods.

  • You can now filter on release_name when you make a deployments() query to the Houston API.

  • You can now use containerd-based Astro Runtime images on an Astronomer Software cluster with a self-managed private CA certificate. To configure a self-managed private CA certificate, add the following configuration to your values.yaml file and apply the configuration to your cluster:

    astronomer:
    privateCaCertsAddToHost:
    enabled: true
    hostDirectory: /path/to/docker/certs.d
    addToContainerd: false
    containerdCertConfigPath: /path/to/containerd/certs.d
    containerdConfigToml: ~
    containerdnodeAffinitys: []
  • You can now make a createDeployment or upsertDeployment query by specifying a Workspace name or label instead of a Workspace ID.

  • You can now disable the astro-cli Pod to free up resources on your cluster. This Pod is typically only used in airgapped clusters that can't access https://install.astronomer.io. To disable the Pod, add the following configuration to your values.yaml file and apply the change to your cluster:

    astronomer:
    install:
    cli-enabled: true
  • Astronomer Software now redeploys your Deployment when you switch your executor type.

  • You no longer have to manually define your private registry in the configuration for Vector logging sidecars..

Bug fixes

  • Fixed an issue where Astronomer users would occasionally not be associated with their related Azure AD/ Microsoft Entra ID accounts when added to Astronomer using SCIM.

  • The Houston API now validates updateDeployment queries to ensure that Deployment resource limits and requests are set correctly.

  • Fixed an issue where the Core Container Status section of the Metrics tab would occasionally show unhealthy containers with a healthy status.

  • Fixed an issue where Deployments would occasionally not recreate the correct resources when switching from the Kubernetes executor to the Celery executor.

  • Fixed an issue where deploys could fail when using a self-signed certificate signed by a private certificate authority.

  • Fixed an issue where Deployments would not have default configuration values as expected when a configuration was missing.

  • Fixed an issue where you couldn't search for a user in the Software UI by their user ID.

  • Fixed the following vulnerabilities:

0.33.3

Release date: January 19, 2024

Additional improvements

Bug fixes

  • Fixed an issue where the Workspace list page in the Software UI would show an error if any Workspace had an empty description.

  • Fixed an issue in 0.33.2 where you couldn't migrate a Deployment from Astronomer Certified to Astro Runtime.

  • Fixed an issue where a Deployment would incorrectly appear as unhealthy if you scaled down its number of triggerers to zero.

  • Fixed the following vulnerabilities:

0.33.2

Release date: November 20, 2023

Change to behavior for interacting with deprecated Runtime versions

In 0.33.2, non-System Admin users can now update Deployments using deprecated versions of Astro Runtime. By default, non-System Admin users can now interact with Deployments using deprecated Runtime versions, but only System Admins can create new Deployments with deprecated Runtime versions. As a result of this change, the enableSystemAdminCanUseNonSupportedRuntime key has been replaced with enableSystemAdminCanUseAllRuntimes. To set the new flag, add the following configuration to your values.yaml file:

astronomer:
houston:
config:
deployments:
enableSystemAdminCanUseAllRuntimes: true

Additional improvements

  • You can now configure a global index name prefix to use for both Fluentd and sidecar-based logging, which allows Astronomer Software to retain logs when you migrate between logging solutions. To enable this feature, add the following lines to your values.yaml file:

    global:
    logging:
    indexNamePrefix: <your-index-prefix>
  • Deprecated Kubernetes 1.23

Bug fixes

0.33.1

Release date: October 13, 2023

Additional improvements

  • You can now configure a service account specifically for your image registry using by setting astronomer.registry.serviceaccount in your values.yaml file.
  • The Kibana logging dashboard now includes a default index.

Bug fixes

  • Fixed an issue where if you queried a Deployment name that belonged to two different Deployments in two different Workspaces, the Houston API might retrieve the unintended Deployment.

  • Fixed an issue where you could create users with the Houston API when SCIM was enabled and userManagement.enable was false.

  • Fixed an issue where some dashboards on Grafana didn't load properly.

  • Fixed an issue where the Houston API CreateDeployment request would return a successful response even though no Deployment was created due to no specified Airflow version.

  • Fixed an issue where a System Admin user that did not belong to a Team could delete the Team from the Software UI.

  • Fixed an issue where syncing an IdP group from Okta failed when SCIM was enabled and a user account was removed only from Astronomer Software.

  • Fixed an issue where adding a user through SCIM provisioning that already exists on an Astronomer Software Azure cluster would throw an error instead of updating the existing user.

  • Fixed an issue where the user login process would be unresponsive if the Houston API failed to retrieve IdP group information from Azure.

  • Fixed an issue where the Software UI would show Deployments as healthy even when triggerer Pods were failing.

  • Fixed an issue where a user who was deleted from Astronomer Software would not appear when they were reinvited through a Team.

  • Fixed an issue where the System Admin page in the Software UI had entries that didn't fit the page.

  • Astronomer Software now throws an error if you attempt to install it with an unsupported version of Kubernetes.

  • Fixed an issue where using the Houston API to query for a Deployment that didn't exist returned a non-descriptive error.

  • Fixed an issue where ap-blackbox-exporter did not respect global network policies.

  • Fixed the following vulnerabilities:

0.33.0

Release date: September 8, 2023

Automatic PGBouncer connection scaling

Astronomer Software can now automatically scale the size of PGBouncer connection pools based on your Airflow component counts and Airflow configuration, instead of solely based on total AU. This improves performance, scalability, and utilization of database connections across all Deployments.

This feature is off by default. You can enable it by setting deployments.pgBouncerResourceCalculationStrategy: airflowStratV2 in your values.yaml file. To revert back to previous behavior, set this key to auStratV1 instead.

Additional improvements

  • You can now disable Airflow and platform alerts on the Prometheus alerts dashboard by setting prometheus.defaultAlerts.airflow.enabled and prometheus.defaultAlerts.airflow.enabled to false in your Prometheus Helm chart. If you disable these alerts, you can still add back specific alerts or configure custom alerts using prometheus.defaultAlerts.additionalAlerts. See Create custom alerts.
  • Added support for Kubernetes 1.27.
  • The Workspace Deployments page is now paginated in the Astronomer UI.
  • The Extra Capacity field in the Astronomer UI now shows up to 6 digits of AU.

  • When you create or update a Deployment and select a Runtime version, the Astronomer UI now shows only the latest supported Astro Runtime patch for each supported Astro Runtime major version.
  • You can now set deployments.canUpsertDeploymentFromUI: false to prevent all users besides System Admins from updating Deployments and environment variables through the Astronomer UI.
  • You can now overprovision the triggerer-log-groomer component.

Bug fixes

  • Fixed an issue where a Deployment using Runtime 8 or earlier with the Celery executor would show as healthy in the Software UI even when workers were unavailable.

  • Fixed an issue where Grafana could not start up on an OpenShift cluster.

  • Fixed an issue where configurations in astronomer.houston.config.deployments.components applied only to Deployments that were created after the configuration was set.

  • Fixed a security vulnerability in logging.

  • Fixed the following vulnerabilities:

0.32.0

Release date: April 28, 2023

Clean Deployment task metadata

You can now clean task data from your Deployments by exporting it to an external storage service. This workflow reduces the amount of data Airflow stores in your Deployment metadata database by archiving data that you don't need to access on a regular basis. To configure this job, see Clean Deployment task metadata.

Programmatically create and update Deployments with the Houston API

You can now programmatically create or update Deployments using the Houston API upsertDeployment mutation. Unlike createDeployment, the upsertDeployment mutation includes keys for configuring Deployment resources such as environment variables. See Create or update a Deployment with configurations.

Reduce resource requests for Airflow components in development environments

You can reduce the amount of CPU and memory that an Airflow component requests in development environments, allowing you to more efficiently provision resources based on the requirements for your development Deployments. See Underprovision Airflow resources for configuration steps.

New cron job to clean Deployment task data

You can now clean task data from your Deployments by exporting it to an external storage service. This workflow reduces the amount of storage Astronomer Software uses by archiving data that you don't need to access on a regular basis. See Configure a Deployment for configuration steps.

Assign System-level permissions to Teams

You can assign the System Admin, System Editor, and System Viewer permissions to teams by setting the following values in your values.yaml file:

# Auth configuration.
auth:
openidConnect:
idpGroupsImportEnabled: true
# Optional configuration. Set to assign System-level permissions using Teams.
manageSystemPermissionsViaIdpGroups:
enabled: true
systemAdmin: ["<your-system-admin-groups>"] // Only these groups will be treated as SysAdmin Groups
systemEditor: ["<your-system-editor-groups>"]
systemViewer: ["<your-system-viewer-groups>"]

When coupled with disabling individual user management, this feature allows you to control all user permissions on Astronomer Software exclusively through your identity provider. For more information, see Import IdP groups.

PostgreSQL 15

Astronomer Software version 0.32 upgrades PostgreSQL from 11.18.0-1 to 15. If you use in-cluster PostgreSQL for your workflows, upgrading to Software 0.32 without pinning your PostgreSQL version can impact your workflows. See the Upgrade to Postgres 15 for upgrade considerations and steps.

Additional improvements

  • Added support for using git-sync with a private image registry.
  • The root user feature introduced in Astronomer Software version 0.31 has been deprecated. System Admins now have the highest level of permissions on the platform.
  • Workspaces are now required to have unique names. If you have existing Workspaces with identical names, upon upgrade the duplicate names will be appended with an underscore and a number.
  • If you configured git-sync deploys for a Deployment, you can now view error logs emitted from the git-sync Kubernetes Pod in the Software UI.
  • You can now configure a custom indexing pattern for Vector logging sidecars by setting both elasticsearch.curator.age.timestring and astronomer.houston.config.deployments.helm.loggingSidecar.indexPattern in your values.yaml file.
  • You can now configure custom environment variables for ElasticSearch-based custom logging using the astronomer.customLogging.extraEnv value in your values.yaml file.
  • The astronomer.houston.config.deployments.sysAdminScalabilityImprovementsEnabled key has been replaced with astronomer.houston.config.deployments.performanceOptimizationModeEnabled for improved performance across additional Software UI views.

Bug fixes

0.31.3

Release date: February 24, 2023

Additional improvements

  • You can now configure extraVolumes and extraVolumeMounts in the Alertmanager Helm chart, which can be useful for storing secret credentials for services that read your alerts.
  • You can now use astronomer.houston.ingress.annotation in the Astronomer Helm chart to configure custom ingress annotations for Houston.
  • You can now upgrade the Airflow Helm chart for individual Deployments by running yarn upgrade-deployments <deployment-id> from within the Houston Pod.

Bug fixes

  • Fixed an issue where you could not set AIRFLOW__LOGGING__REMOTE_BASE_LOG_FOLDER in a Deployment if you were using an Astronomer Certified image.

  • Astronomer Software now filters orphaned Deployments and Workspaces owned by users who were removed from an identity provider (IdP) group with SCIM enabled.

  • Fixed a security vulnerability where you could query Elasticsearch logs for a Deployment from a different Deployment.

  • Fixed an issue where authentication tokens were visible in Nginx logs produced by the Software UI.

  • Fixed an issue where deploying an image with the docker/build-push-action GitHub action could produce errors in Houston that affected the entire Astronomer Software installation.

  • Fixed the following vulnerabilities:

0.31.2

Release date: February 2, 2023

Additional improvements

  • Support for Kubernetes 1.25 and 1.26.

  • You can now configure custom annotations for Houston ingress by setting astronomer.houston.ingress.annotation in your values.yaml file.

  • The System Admin Deployments list in the Software UI is now paginated.

  • You can now use the following values in your values.yaml file to configure resource allocation for the git-sync relay service:

Bug fixes

0.31.1

Release date: December 23, 2022

Additional improvements

  • You can now configure extraFlags for the Prometheus startup command in the Prometheus Helm chart.

Bug fixes

0.31.0

Release date: December 7, 2022

View and export task usage metrics

You can now view task usage metrics from the Software UI.

Task usage metrics provide an overview of your Airflow task runs and can help you quickly identify Deployments where more tasks are running or failing than expected.

To configure the feature, see Set up task usage metrics.

New root user role

Astronomer Software's role-based access control (RBAC) system now supports a single root user for each installation. The root user has a non-configurable username and autogenerated password stored as a Kubernetes secret in your installation.

See Manage the root user.

Manage Astronomer users through a SCIM integration

Astronomer Software now supports managing users through System for Cross-domain Identity Management (SCIM), which allows you to automatically provision and deprovision users based on templates for access and permissions. See Manage users with SCIM.

Invite users only through Teams

Using the new root user feature, you can now configure Astronomer Software so that users are managed exclusively through Teams. This helps you better integrate with your identity provider (IdP) by ensuring that all users on your platform are authenticated and managed through the IdP. See Disable individual user management.

New default resource limits and requests

Astronomer Software 0.31 includes new default resource limits and requests on the following resources:

  • Alertmanager
  • Elasticsearch
  • NATS
  • PostrgeSQL
  • STAN
  • Nginx
  • Grafana
  • Blackbox exporter

You might experience OOMKill errors or unexpected behavior after upgrading if you use resources beyond the new default limits. To minimize disruption, view resource usage for these components in Grafana prior to upgrade and compare this usage to the default resource limits in the Astronomer Helm chart.

If your current usage is expected and higher than the default resource limits, update the limits in your values.yaml file before upgrading to Astronomer Software 0.31.

Additional improvements

  • You can now set a custom security context for es-client by setting elasticsearch.client.securityContext.capabilities.add={} in the ElasticSearch Helm chart.
  • The Deployment users page is now paginated in the Software UI.
  • You can now set astronomer.registry.logLevel to filter which types of logs appear in your Docker registry.

0.30.1

Release date: September 12, 2022

Bug fixes

0.30.0

Release date: August 29, 2022

Breaking Change for Azure Database for PostgreSQL

A change in 0.30 enabled the trgm extension for PostgreSQL. If you use Azure Database for PostgreSQL as your database backend, you need to enable the pg_trgm extension before upgrading to Software 0.30 using either Azure portal or the Azure CLI. See Azure documentation for configuration steps.

If you don't complete this setup before your upgrade, the upgrade will fail.

Improved token refreshing for IdP integrations

The Software UI now refreshes your JSON web token (JWT) based on the validity of your authentication token from your IdP. This means that as long as you stay logged in to your IdP, you no longer have to refresh the Software UI to continue accessing the Software UI, Astro CLI, and Houston API.

Additionally, if you change a user's access to Astronomer from your IdP, their permissions will be automatically updated in Astronomer after their current IdP token expires. If you remove a user completely from Astronomer, they are automatically logged out of the Software UI and CLI after their current IdP token expires.

As part of this change, you can now configure jwt.authDuration in your Houston Helm configuration. If a user is logged on longer than authDuration, they will be immediately logged out regardless of the status of their JWT or authentication token.

Additional improvements

  • Workspace users are now paginated in the Software UI.
  • You can now configure credentials for a private image registry by specifying a secret you create instead of a username and password. The secret is attached to any Pods that need to access the registry.
  • You can now specify authUrlParams for your identity provider (IdP) in values.yaml.
  • System Editors can no longer manage Teams or users in a Workspace. These permissions are now available only at the System Admin level.

Bug fixes

  • Fixed an issue where updateRuntimeCheck.enabled:false did not properly stop an Astronomer Software installation from checking for Runtime updates.
  • Fixed an issue where applying an IAM role to a Deployment would reset the Deployment's Extra Capacity setting back to the default of 0 AU.
  • Fixed an issue where System Admins could receive an error when trying to view a Team imported from a different IdP than their current one.
  • When a System Admin makes a change to a Team, that change now appears in the UI without needing to refresh the page.
  • Configurations for disabling a specific executor type in values.yaml are now reflected in the Software UI.
  • Fixed an issue where Workspace-level service accounts could view Deployment information from Deployments outside of their Workspace.
  • Fixed an issue where updating the role of a user in a Team using the Astro CLI would not throw an error as expected.
  • Fixed an issue where JSON web tokens persisted after a user logged out if idpGroupsRefreshEnabled was set to false.
  • Users authenticating with Google Direct are no longer automatically logged out of Astronomer Software after 1 hour.

0.29.5

Release date: October 11, 2022

Breaking change

(https://github.com/kubernetes/kubernetes/issues/65106) that occurs when you upgrade Helm charts that include duplicate keys in an env array. If you have a Helm chart with duplicate keys and upgrade to Astronomer Software 0.29.3+, all key-value pairs with the duplicate key are removed from your environment.

To preserve duplicate keys in your Helm chart, you can either reapply the values after upgrading, or you can use the --reset-values flag when you run the upgrade script as described in Upgrade Astronomer.

Additional improvements

  • Improved the startup time for the platform NATS server.
  • You can now configure a livenessProbe and readinessProbe specific to Prometheus in the Prometheus Helm chart.
  • You can now configure a specific securityContext for Fluentd Pods and containers in the Fluentd Helm chart.

Bug fixes

  • Fixed an issue where upgrading Astronomer Software with a custom houston.deployments.components value in Helm could break the Software UI.

  • Fixed an issue where upgrading a Deployment from Airflow 1.10.15 to 2.3 can prevent you from configuring the Deployment's resources in the Software UI.

  • Fixed an issue where you couldn't run Houston API queries for Deployments using releaseName and label
  • Fixed an issue where a user could not log in through Azure AD SSO if the user belonged to a group without a displayName

0.29.0

Release date: June 1, 2022

Support for Astro Runtime images

You can now use Astro Runtime images in your Software Deployments. Additionally, you can now select Runtime images when setting Image Version for a Deployment in the Software UI.

Functionally, Runtime images are similar to Certified images. They both include:

  • Same-day support for Apache Airflow releases
  • Extended support lifecycles
  • Regularly backported bug and security fixes

Astro Runtime includes additional features which are not available in Astronomer Certified images, including:

  • The astronomer-providers package, which includes a set of operators that are built and maintained by Astronomer
  • Airflow UI improvements, such as showing your Deployment's Docker image tag in the footer
  • Features that are exclusive to Astro Runtime and coming soon, such as new Airflow components and improvements to the DAG development experience

To upgrade a Deployment to Runtime, follow the steps in Upgrade Airflow, making sure to replace the Astronomer Certified image in your Dockerfile with an Astro Runtime version.

Use a custom container image registry to deploy code

You can now configure a custom container image registry in place of Astronomer's default registry. This option is best suited for mature organizations who require additional control for security and governance reasons. Using a custom registry provides your organization with the opportunity to scan images for CVEs, malicious code, and approved/ unapproved Python and OS-level dependencies prior to deploying code. To configure this feature, see Configure a custom image registry.

Export task logs using logging sidecars

You can now configure logging sidecar containers to collect and export task logs to ElasticSearch. This exporting approach is best suited for organizations that use Astronomer Software in a multi-tenant cluster where security is a concern, as well as for organizations running many small tasks using the Kubernetes executor. To configure this feature, see Export task logs.

Simplified configuration for namespace pools

The process for configuring namespace pools has been simplified. As an alternative to manually creating namespaces, you can now delegate the creation of each namespace, including roles and rolebindings, to Astronomer Software. While this feature is suitable for most use cases, you can still manually create namespaces if you want more fine-grained control over the namespace's resources and permissions. For more information, see Namespace pools.

0.26.4

Release date: November 22, 2021

Support for Airflow 2.2.0

Apache Airflow 2.2.0 is an exciting milestone in the open source project. Most notably, this release introduces custom timetables and deferrable operators.

Custom Timetables

Timetables are a powerful new framework that you can use to create custom schedules using Python. In an effort to provide more flexibility and address known limitations imposed by cron, timetables use an intuitive data_interval that, for example, allows you to schedule a DAG to run daily on Monday through Friday, but not on the weekend. Timetables can be easily plugged into existing DAGs, which means that it's easy to create your own or use community-developed timetables in your project.

For more information on using timetables, read the Apache Airflow Documentation.

Deferrable Operators

Deferrable operators are a new type of Airflow operator that promises improved performance and lower resource costs. While standard operators and sensors take up a Worker or Scheduler slot even when they are waiting for an external trigger, deferrable operators are designed to suspend themselves and free up that Worker or Scheduler slot while they wait. This is made possible by a new, lightweight Airflow component called the Triggerer.

As part of supporting deferrable operators, you can provision multiple Triggerers on your Astronomer Deployments. By provisioning multiple Triggerers, you can ensure that tasks using Deferrable Operators are run even when one Triggerer goes down. For more information about configuring Triggerers and other resources, see Configure a Deployment.

CLI Verbosity Flag

You can now specify a --verbosity flag for all Astronomer CLI commands. When you specify this flag with a CLI command, the CLI prints out Logrus logs as the command runs. This is useful for debugging any errors that might result from a CLI command.

The flag prints out different levels of logs depending on the value that you pass it. Each possible value (debug, info, warn, error, fatal, and panic) maps to a different Logrus logging level. For more information about these logging levels, read the Logrus documentation.

Minor Improvements

  • You can now create a custom set of cluster-level permissions for the Astronomer Commander service by setting astronomer.global.clusterRoles: false in your values.yaml file and pushing a new RoleBinding to a pre-created Kubernetes namespace.
  • In the astronomer.houston.config section of your values.yaml file, you can now configure a list of allowedSystemLevelDomains []. If you configure this list, only users with emails from domains specified in the list (for example, <company>.com) can be granted System Admin privileges.
  • Greatly improved load times for the System Admin page in the UI.
  • You can now specify a node port for 3rd party ingress controllers with a service type of nodePort.
  • The naming format of service account pods has been changed from <release-name>-dags-prod-worker-serviceaccount to release_name-dags-prod-airflow-worker.

Bug Fixes

  • Fixed an issue where you could not update an existing Deployment's IAM role via the Astronomer CLI
  • Fixed an issue where Deployments would not work on clusters with custom domains
  • Fixed error handling when interacting with a Deployment that wasn't fully spun up
  • Added a new validation step for Airflow Helm chart values configured in the astronomer.houston.config.deployments.helm.airflow section of values.yaml
