How to set charm channels within a bundle

Channels within a bundle allow you to describe the preferred channel to use when deploying a non-local charm. Each application allows the changing of a charm’s channel to configure the location from the remote store.

For example, to get the latest edge release of mysql from the Charmhub store or alternatively to get the stable release of wordpress from the charm store:

  charm: mysql
  channel: latest/edge
  charm: cs:wordpress
  channel: stable
