How to set up a charm project
You’ve installed (and configured) Charmcraft. This document shows you how to use it to set up the project for an Ops-based charm.
This is the recommended way to initialise a charm.
To create your charm’s file tree structure, simply execute:
$ mkdir my-new-charm; cd my-new-charm $ charmcraft init Charm operator package file and directory tree initialized. TODO: README.md: Describe your charm in a few paragraphs of Markdown README.md: Provide high-level usage, such as required config or relations actions.yaml: change this example to suit your needs. config.yaml: change this example to suit your needs. metadata.yaml: fill out the charm's description metadata.yaml: fill out the charm's summary metadata.yaml: replace with containers for your workload (delete for non-k8s) metadata.yaml: each container defined above must specify an oci-image resource src/charm.py: change this example to suit your needs. src/charm.py: change this example to suit your needs. src/charm.py: change this example to suit your needs.
This creates all the essential files for your charm, including
src/charm.py skeleton and various items of metadata.
Charmcraft implements the Ops framework. This is the recommended way to create a charm.
Charmcraft can be used to initialise both Kubernetes and machine charms. However, at present the files are by default configured for Kubernetes charms, and to make them suitable for machine charms one must make certain small adjustments.
