Is it possible to manually start Juju hooks?

  • 772

I know you can debug hooks in error state by running juju debug-hooks nodemane and then running juju resolved --retry nodename. Is it possible to run or rerun hooks that are not in an error state?

Thanks

    Yes using actions https://jujucharms.com/docs/1.20/actions

    Actions are exposed as of Juju 1.23. In Juju 1.22, they are only enabled in the CLI when JUJU_DEV_FEATURE_FLAG=actions is set.

    If you don't need the hooks to execute in a 'hook environment' then you can just execute them via ssh as a normal script.

  2. An alternative way is to use 'juju run'.

    juju run --unit someunit/1 'hooks/some-hook'

    When using 'juju run' for a unit or all units of a service, the working directory is set to the charm, so you can access the hooks directly.
