GitHub Actions templates for deploying code to Astro
GitHub Action templates use the Astronomer-maintained deploy-action, which is available in the GitHub Marketplace. This action automates the deploy process and includes additional features for more complex automation workflows. Specifically, the action can automatically:
- Choose a deploy type based on the files that were changed in a commit. This allows you to use the same template for dag deploys and image deploys.
- Test dags as part of the deploy process and prevent deploying if any of the tests fail. These tests are defined in the
testsdirectory of your Astro project. - Create a preview Deployment to test your code before deploying to production. A Deployment preview is an Astro Deployment that mirrors the configuration of an existing Deployment.
- Allows you to choose the type of code deploys used by the automation:
- (Default)
infer image-and-dagsdags-onlydbt
- (Default)
If you have one Deployment and one environment on Astro, use the single branch implementation. If you have multiple Deployments that support development and production environments, use the multiple branch implementation. If your team builds custom Docker images, use the custom image implementation. If you do not have access to Astronomer’s deploy-action, use the private network templates.

Deploy type
The deploy-action includes several deploy types for you to choose a specific type of code deploy for your CI/CD processes.
(Default) infer
By default, the deploy-action uses infer, which allows it to determine the type of code deploy to use based on the types of files changed in a commit: Dag or Astro project. If you committed changes only to dag files, the action triggers a dag deploy. If you committed changes to any other file, the action triggers an image deploy, or image-and-dags. This setting does not include dbt deploy types. See default deploy action.
image-and-dags
The image-and-dags option enables the Deploy Action to make a full project deploy, which includes both images and dags.
dags-only
The dags-only deploy option enables the deploy action to deploy only the dags in your Astro project’s dags directory to your Deployment.
dbt
The dbt deploy option enables the Deploy Action to deploy dbt projects to Astro, when you provide the path to a directory in your GitHub repo that contains your dbt project. See dbt deploy action.
