The manifest.yaml file in your charm (bundle) is a file that contains information that Charmhub and charmcraft can use to identify the version, build time, OS name, and version at build time, as well as the architectures that the charm (bundle) can run on.

The file is created automatically by charmcraft pack and you can inspect it by unzipping the .charm archive (unzip <charm name>.charm ) or by deploying the charm, SSHing into one its units, and inspecting the charm directory in there (e.g., for unit 0: ls agents/unit-<charm name>-0/charm).
