> Healthcheck: have a query param to return 503 code if degraded
> --------------------------------------------------------------
>
> Key: JAMES-4070
> URL: https://issues.apache.org/jira/browse/JAMES-4070
> Project: James Server
> Issue Type: Improvement
> Reporter: hung
> Priority: Major
> Time Spent: 1h 50m
> Remaining Estimate: 0h
>
> *Why*
> k8s consider a pod not healthy when receiving the response code >= 400.
> James healthcheck response code:
> 200: All checks have answered with a Healthy or Degraded status. James
> services can still be used.
> 503: At least one check have answered with a Unhealthy status
> `degraded` with 200 code won't trigger k8s pod restart.
> We should have an option to restart the k8s pod when `degraded` performance
> *How*
> We could add a flag as a query parameter to consider degraded as failed. EG
> `GET 127.0.0.1:8000/healthcheck/checks/ImapCheck?strict`
> Would return 503 response code if unhealthy and degraded
> While
> `GET 127.0.0.1:8000/healthcheck/checks/ImapCheck`
> Would return 503 when unhealthy and 200 for degraded.
> We would need to implement `GET 127.0.0.1:8000/healthcheck?strict` too.
