Astro Private Cloud (APC) ships with and requires a number of adjacent technologies that support it, including Kubernetes, Helm, and Apache Airflow itself. This guide provides a reference of all required tools and versions for running APC.
While the tables below reference the minimum compatible versions, we typically recommend running the latest versions of all tooling if and when possible.
Astronomer does not support Postgres versions that are beyond their end-of-life date. You can check to see the currently supported versions of Postgres. The following table shows version compatibility information for all currently supported versions of APC. Check APC lifecycle schedule for more information about supported versions of APC.
For more detail about the changes in each APC release, see the APC Release Notes.
Only Astronomer-distributed images supporting Airflow 2.x are compatible with all versions of APC. Astro Runtime maintenance is independent of Astro Private Cloud maintenance. For more information, see Astro Runtime maintenance and lifecycle policy.
In general, APC will support a given version of Kubernetes through its End of Life. This includes Kubernetes upstream and cloud-managed variants like GKE, AKS, and EKS. When a version of Kubernetes reaches End of Life, support will be removed in the next major or minor release of APC. For more information on Kubernetes versioning and release policies, refer to Kubernetes Release History or your cloud provider.
See the following table for all supported Kubernetes versions in each maintained version of APC.
