Charm statuses
This is an work-in-progress article. Do not use it in production! Contact Canonical Data Platform team if you are interested in the topic.
The charm follows standard Juju applications statuses. Here you can find the expected end-users reaction on different statuses:
| Juju Status | Message | Expectations | Actions |
|---|---|---|---|
| active | any | Normal charm operations | No actions required |
| waiting | any | Charm is waiting for relations to be finished | No actions required |
| maintenance | any | Charm is performing the internal maintenance (e.g. cluster re-configuration) | No actions required |
| blocked | any | The manual user activity is required! | Follow the message hints (see below) |
| blocked | Failed to set up relation | The relation between two applications failed to be created. Most probably it is a regression of the recent changes in applications | Check Juju debug-log. Increase debug level and reproduce the issue. Report as an issue with debug logs attached (if reproducible). Consider to try previous revision for both applications |
| blocked | Failed to initialize mysql relation | The same as “Failed to set up relation” | See “Failed to set up relation” |
| blocked | Failed to remove relation user | TODO: clean manually? How to unblock? | |
| blocked | Failed to install and configure MySQL | TODO | |

| terminated | any | The unit is gone and will be cleaned by Juju soon | No actions possible |
| unknown | any | Juju doesn’t know the charm app/unit status. Possible reason: K8s charm termination in progress. | Manual investigation required if status is permanent |
