confdb

The confdb interface enables snaps to access to specific confdb views.

There are two fields that together identify the view being accessed: account and view. There is also an optional role field which may only take the value of “custodian”, if the snap is a custodian for the confdb-schema being accessed.

See the Confdb configuration mechanism for implementation details, and Configure snaps with confdb to use confdb with your own snaps.

 read-sensor-params:
  interface: confdb
  account: acme
  view: sensors/read-sensor1-parameters

See Interface management and Supported interfaces for further details on how interfaces are used.

ⓘ Confdb is currently considered an Experimental feature and implementation details may change as development progresses.

Auto-connect: no, but plugs are auto-connected if the confdb’s account is the same as the snap’s publisher.
