Pack a hooks-based charm

Introduced in Charmcraft 1.4

See first: Ops | Turn a hooks-based charm into an ops charm

Suppose you have a legacy hooks-only charm, for example, tiny-bash, which you can clone with:

git clone https://github.com/erik78se/tiny-bash

To make it packable by Charmcraft, all you need to do is navigate inside the charm directory and create a charmcraft.yaml file with the part definition for a hooks-based charm, as shown below:

type: charm

bases:
  - build-on:
    - name: "ubuntu"
      channel: "20.04"
    run-on:
    - name: "ubuntu"
      channel: "20.04"

parts:
  tiny-bash:
    plugin: dump
    source: .
    prime:
      - LICENSE
      - README.md
      - config.yaml
      - copyright
      - hooks
      - icon.svg
      - metadata.yaml

Then, pack the charm by running:

charmcraft pack

The charm file should contain all the files listed in the prime section of the tiny-bash part and the charm manifest.

user@host:~$

unzip -l tiny-bash_ubuntu-20.04-amd64.charm
