Automatic hook retries in Juju 2.0

[Bogdan Teleaga]

Hey Casey,

They are all retried using the same policy.


The constants that control the delay are here:
https://github.com/juju/juju/blob/master/apiserver/retrystrategy/retrystrategy.go#L21

Basically it's an exponential backoff with a factor of 2 that starts at 5 seconds and has a maximum of 5 minutes, so 5, 10, 20...up to 300 seconds.

Iirc attempting a manual retry will reset this timer. It also never gives up.

Cheers,
Bogdan

What is the intended behavior for automatic hook retries in Juju 2.0?

Specifically, I'd like to know, as a Juju user:

Are errors in hooks all retried with the same policy, or are some retried with a different policy / strategy than others (install, for example)?

Is there a limit to the number of times Juju will retry a hook error before "giving up"?

What kind of delay can I expect between retries?

Thanks,
Casey
