Upgrade Composer by March 25, 2024

As a Cal-ITP data consumer, I would like Composer to be upgraded to ensure continuity of Airflow workflows and avoid potential failures due to using an unsupported Composer version.

Context:

We got an email from GCP today:

What do you need to know? On March 25, 2024, the last released Composer 1 version, Composer 1.20.12, will reach its planned end of support according to the versioning model. As of this date, Cloud Composer 2 will be the only General Availability product line and will continue to get new features and updates. If you use earlier Composer 1 versions, the end of support will be reached sooner or it may have already passed. Please refer to the list of Composer versions for details.

While your Cloud Composer 1 environments will continue to be available after their end of support, Cloud Support or Cloud Composer teams will not be able to support any potential issues in these environments. What do you need to do?

Take the following actions before your environments’ end of support dates:

If your Composer 1 environment relies on Airflow 1, follow this guide. If your Composer 1 environment relies on Airflow 2, follow this guide.

Your affected Cloud Composer environments are in the following projects:
