In Juju, a charm resource is additional content that a charm can make use of, or may require, to run.

A resource can have one of two basic types – file and oci-image. These can be specified as follows:

  1. If the resource is type ‘file’, you can specify it by providing

    a. the resource revision number or

    b. a path to a local file.

  2. If the resource is type ‘oci-image’, you can specify it by providing

    a. the resource revision number,

    b. a path to a local file = private OCI image,

    c. a link to a public OCI image.

If you choose to provide a path to a local file, the file can be a JSON or a YAML file with an image reference and optionally a username and a password (i.e., an OCI image resource).
