What problem does this PR solve?

  • fe rolling restart capability
  • be rolling restart capability

Principle:

restart capability triggers a restart by patching the template metadata of all the pods of resource with apache.doris.org/restartedAt annotation.

Directions:

  1. Add corresponding annotations to dcr.metadata.annotations to rolling restart.
    a. apache.doris.be/restartedAt restart be
    b. apache.doris.fe/restartedAt restart fe
  2. Try to ensure that the time is after the current time. The time in the past will be regarded as an invalid parameter and the restart will be rejected. The format can refer to this command: date +"%Y-%m-%dT%H:%M:%S%:z".
