Configmaps in k8s charms

charm
2

Juju charms don’t create config maps directly - they specify file sets which are mounted at specified locations in the docker images.
Internally, Juju creates a config map volume source to do that. The config map is called:
<appname>-<filesetname>-config

So if the myapp charm produced a pod spec yaml like this:

    files:
      - name: foocfg
        mountPath: /var/lib/foo
        files:
          file1: |
            [config]
            foo: bar

There would be a config map called myapp-foocfg-config created to back the volume mounted into the pod.
