----------------------------------------

             Summary: Use args Instead of command in Kubernetes Executor Worker Pods
                 Key: AIRFLOW-6780
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-6780
             Project: Apache Airflow
          Issue Type: Bug
          Components: executor-kubernetes
    Affects Versions: 1.10.9, 1.10.8, 1.10.7
            Reporter: Brandon Willard
            Assignee: Daniel Imberman


The worker pods created by the Kubernetes Executor are hard-coded to use [the {{command}} field instead of {{args}}|[https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#notes]!|https://kubernetes.io/docs/tasks/inject-data-application/define-command-argument-container/#notes].  The result is a worker pod that ignores its image's entry-point and prevents the standard means of executing container preparation code --- among other things.

This --- alongside the issues stated in [AIRFLOW-6778|https://issues.apache.org/jira/browse/AIRFLOW-6778] and [AIRFLOW-3126|https://issues.apache.org/jira/browse/AIRFLOW-3126] --- renders worker nodes virtually incompatible with a dynamic, shared DAGs volume (unless dependencies are installed in the image and never change).
