Juju Charm Layers Index

This repo is the index of layers available for building Juju Charms.

Each layer is represented by a small JSON file in either the layers or interfaces directory, depending on the type of layer, and each file should conform to the schema encoded in the schema.json file. Specifically, it must contain at least the following fields:

• id: The name by which the layer will be referenced in layer.yaml, e.g., basic
• name: The human-friendly name of the layer
• repo: The URL of the git or bzr repo for the layer
• summary: A short description of the purpose of the layer

The file can also contain a docs field, which can specify a link to documentation for the layer. If not specified, a link to a README.md file will be generated, if the repo is hosted on GitHub or Launchpad, or the link to the repo will be used.

The name of the file must match the ID field, with a .json suffix.

To add or modify a layer in the index, just create a PR against this repo in which you have added the appropriate JSON file and run the update_readme.py script to update the index below.

If you would like to build a charm using a fork of this repo (e.g., to test a new layer before submitting a PR, if you have private layers or layers under test and don't want to use local layers, etc.), you just need to pass in a URL where the repo contents are available via HTTP/S to charm-build. For example, to build using a fork in your personal namespace in GitHub:

charm build --interface-service https://raw.githubusercontent.com/myuser/layer-index/mybranch/
