Working on building the Charmed Kafka snap, as part of Canonical Data Platform. Have had issues with deployments where Kafka syslogs ran through a snap app returns:
java.io.IOException: Mount point not found
Likely cause is that it can’t read the necessary mounts from within the snap confinement.
Have added the
mount-observe plug to the snap itself - https://github.com/canonical/charmed-kafka-snap/pull/31
Just need it enabled.
