研究方向

以 airflow.yml 和 AirflowCluster 的 reconciliation 路徑作為入口;重現 PostgreSQL 初始化失敗,刪除並重新套用資源,並檢查 operator 在重試後如何記錄終止失敗。完成的標準是:修正連線並重新套用後,資料庫初始化和叢集部署會重試並成功,且無需重新安裝 operator 或其 CRD。

  •   kubectl apply -f airflow.yml
    

This config has a bug (wrong database url)

The operator now tries to deploy airflow but the database init fails.
After seven retries all the retries are done and we are in a failure state.
Now I deleted the deployment with
kubectl delete -f airflow.yml

After that i fixed the bug and run kubectl apply -f airflow.yml. This does not try again the database init and just goes to error state.

My expected behavior would be that the database init would tried again and succeeds this time.

Possible solution

Delete the airflow operator and the Custom ressource definition and reinstall the operator. Then apply the correct yaml file. This time the database init succeeds.
