Apache Airflow Helm Chart 1.8.0

on GitHub

Significant Changes

bitnami/postgresql subchart updated to 12.1.9 (#29071)

The version of postgresql installed is still version 11.

If you are upgrading an existing helm release with the built-in postgres database, you will either need to delete your release and reinstall fresh, or manually delete these 2 objects:

    kubectl delete secret {RELEASE_NAME}-postgresql
    kubectl delete statefulset {RELEASE_NAME}-postgresql

As a reminder, it is recommended to set up an external database <https://airflow.apache.org/docs/helm-chart/stable/production-guide.html#database>_ in production.

This version of the chart uses different variable names for setting usernames and passwords in the postgres database.

• postgresql.auth.enablePostgresUser is used to determine if the "postgres" admin account will be created.
• postgresql.auth.postgresPassword sets the password for the "postgres" user.
• postgresql.auth.username and postrgesql.auth.password are used to set credentials for a non-admin account if desired.
• postgresql.postgresqlUsername and postgresql.postresqlPassword, which were used in the previous version of the chart, are no longer used.

Users will need to make those changes in their values files if they are changing the Postgres configuration.

Previously the subchart version was 10.5.3.

Default dags.gitSync.wait reduced to 5 seconds (#27625)

The default for dags.gitSync.wait has been reduced from 60 seconds to 5 seconds to reduce the likelihood of DAGs
becoming inconsistent between Airflow components. This will, however, increase traffic to the remote git repository.

Default Airflow image is updated to 2.5.1 (#29074)

The default Airflow image that is used with the Chart is now 2.5.1, previously it was 2.4.1.

Default git-sync image is updated to 3.6.3 (#27848)

The default git-sync image that is used with the Chart is now 3.6.3, previously it was 3.4.0.

Default redis image is updated to 7-bullseye (#27443)

The default redis image that is used with the Chart is now 7-bullseye, previously it was 6-bullseye.
