Issue
When trying to use this library in Alertmanager, I got the following error:
In fact,
_on_config_changed()doesn't call_generate_privkey().The issue is that a race condition probably causes config-changed to arrive before certificates-relation-joined, which doesn't generate the private key beforehand.
Please note that calling the function multiple times isn't a problem as the function will just skip :)
Solution
Add a call to
_generate_privkey()in the_on_config_changed()handler.
