Custom OAuth Flows

You can now configure a custom OAuth flow as an alternative to Astronomer's default implicit flow. You can customize Astronomer's existing Okta, Google, and GitHub OAuth flows, or you can import an entirely custom OAuth flow. For more information, read Configure a Custom OAuth Flow.

Deploy DAGs via Git Sync

You can now configure a Git repo to continually push DAGs to an Astronomer Deployment via git-sync. DAGs deployed via git-sync automatically appear in the Airflow UI without requiring additional action or causing downtime. For more information, read Deploy DAGs via Git Sync.

External ElasticSearch Logging

Custom ElasticSearch logging tools are now supported via new values in your config.yaml file:

# External ES logging
enabled: true
scheme: https
host: ""
port: ""
secret: ""
#secretName: ~
#awsSecretName: ~
#awsIAMRole: ~
#awsServiceAccountAnnotation: ~

CLI Support for Podman

By default, the Astronomer CLI uses Docker to execute a few specific commands. As an alternative, you can now configure the Astronomer CLI to use Podman instead. For more information, read Run the CLI with Podman.
