Details:

This command upgrades the Juju agent for a controller.

A controller’s agent version can be shown with juju model-config -m controller agent-version. A version is denoted by: major.minor.patch The upgrade candidate will be auto-selected if --agent-version is not specified:

  • If the server major version matches the client major version, the version selected is minor+1. If such a minor version is not available then the next patch version is chosen.
  • If the server major version does not match the client major version, the version selected is that of the client version. The command will abort if an upgrade is in progress. It will also abort if a previous upgrade was not fully completed (e.g.: if one of the controllers in a high availability model failed to upgrade).

Examples:

juju upgrade-controller --dry-run
juju upgrade-controller --agent-version 2.0.1
