jhack show-relation is a command that allows you to visualize the databags of two related Juju applications.
For example, the ingress-per-unit relation between a Traefik unit and a Prometheus unit on kubernetes:
This command is very useful when developing integrations or debugging related charms. You can also make it tail the contents with -w: the table will remain visible and update itself as the databag contents change.
Additional features
- support for peer relations (!)
- support for showing relations in models other than the current one (
-m) - optional suppression of empty databags (
-s) - command promoted to toplevel jhack: it used to be nested under
utils. Now you can simply dojhack show-relation. - better cli help and shortcuts for lazy/busy typers.
- support for “show me the nth relation” instead of having to type out the whole
app-name:endpointthing: if you have 3 relations in your model, you can simply dojhack show-relation -n 1and jhack will print out the 2nd relation from the top (of the same list appearing when you dojuju status --relations, that is.
