pause-after-unit-refresh

config.yaml

options:
  pause-after-unit-refresh:
    description: |
      Wait for manual confirmation to resume refresh after these units refresh

      Allowed values: "all", "first", "none"
    type: string
    default: first

If a refresh is not in progress, changing this value will have no effect until the next refresh.

If a refresh is in progress, changes to this value will take effect before the next unit refreshes. (Any units that are refreshing when the value is changed will finish refreshing.)

Example 1:

4-unit Juju application
- Unit 0: v1
- Unit 1: v1
- Unit 2: v2
- Unit 3: v2
pause-after-unit-refresh changed from all to first
Unit 1 will immediately refresh. If it is healthy after refreshing, unit 0 will refresh

Example 2:

4-unit Juju application
- Unit 0: v1
- Unit 1: refreshing from v1 to v2
- Unit 2: v2
- Unit 3: v2
pause-after-unit-refresh changed from none to all
Unit 1 will finish refreshing to v2. After that, no units will refresh until the user runs the resume-refresh action or runs juju refresh (e.g. to rollback)
