Cloud Composer version list

This page describes the released versions of Cloud Composer images.

About Cloud Composer images

Cloud Composer images bundle Airflow releases with other common binaries and Python libraries. These Docker images are versioned in the following way:

  • In Cloud Composer 3, new Airflow builds become available with each Cloud Composer release. When you create an environment, as an option, you can specify a specific build to use with the chosen Airflow version. After an environment is created, it keeps using the same build of Airflow until you upgrade it to a later build or a later version of Airflow.

  • In Cloud Composer 2 and Cloud Composer 1, new images become available with each Cloud Composer release. When you create an environment, you specify an image version to use. After an environment is created, it keeps using the specified image version until you upgrade it to a later version.

Default and latest versions in Cloud Composer 3

Latest versions in Cloud Composer 3 are most recently released builds of Airflow. If a release contains two Airflow versions, both of them are marked as the latest version in the list of images.

In Cloud Composer 3, the default version is one of the latest versions. When you create a Cloud Composer 3 environment without specifying an Airflow version, this version and build of Airflow are used.

Latest Cloud Composer 2 version

  • In Google Cloud console, you can create a new environment or upgrade an existing environment only using one of the latest supported versions of Cloud Composer.

  • In Google Cloud CLI, API, or Terraform, you can create a new environment using any version that is still within its full support date.

  • In Google Cloud CLI, API, or Terraform, you can upgrade an existing environment to the latest supported versions, three previous versions of Cloud Composer, and to versions with an extended upgrade timeline. It's not possible to upgrade to other versions of Cloud Composer, even if they are still supported and can be used to create a new environment.

Default Cloud Composer 2 version

Each Cloud Composer version supports more than one Airflow version. If you do not specify an image version when you create an environment, the default version is used.

Cloud Composer uses one of the latest Cloud Composer 2 images as the default version.

Cloud Composer versions with an extended upgrade timeline

You can upgrade your environment to a version with an extended upgrade timeline until this version reaches its security notifications end date.

Maintenance release versions of Cloud Composer 1

Maintenance release versions of Cloud Composer 1 are new Cloud Composer 1 images that provide only bug fixes and small improvements.

Support dates for maintenance release versions correspond to the support dates of the last Cloud Composer 1 version 1.20.12 that was released on April 25, 2023.

Versions with disabled upgrades

For some versions of Cloud Composer images, it is not possible to upgrade an environment to a later version:

  • composer-1.7.7-airflow-1.10.2
  • composer-1.7.7-airflow-1.10.1
  • composer-1.7.7-airflow-1.9.0

If you use a version with disabled upgrades, we recommend to create a new environment side-by-side, then migrate all your DAGs to the new environment. Once you confirm that the new environment works, delete the environment with disabled upgrades if you don't need it anymore.

Version support dates

Each Cloud Composer image has a release date and one or more support dates associated with it. The support dates are based on Cloud Composer version deprecation and support periods.

Support dates for Cloud Composer 3 versions can be listed as To be announced. The exact end of support date for these versions is determined when a new minor version of Airflow becomes available in Cloud Composer 3.
