Support `readyz` in REST Submission API

    XMLWordPrintableJSON

Details

    Description

      Like https://kubernetes.io/docs/reference/using-api/health-checks/, we need to provide `/readyz` API.

      As a workaround, we can use the following.

      readinessProbe:
  exec:
    command: ["sh", "-c", "! (curl -s http://localhost:6066/v1/submissions/status/none | grep -q STANDBY)"]
