How to create a charm bundle
From a technical point of view, a charm bundle is fundamentally just a YAML file. This document shows you a few ways in which you can generate this file to create a charm bundle.
From a Juju model
The simplest way to create a charm bundle is to generate it automatically from a Juju model. This is done with the
export-bundle command, which exports a single model configuration. For example, to export the currently active model into file
juju export-bundle --filename mymodel.yaml
This will create the YAML file for your bundle.
If Juju detects that the model uses deployment-specific parameters, it will output a multi-document bundle consisting of a base bundle and an overlay document for the deployment-specific settings.
From an existing bundle
The charm store, Charmhub, contains hundreds of bundles. Download the contents of a bundle similar to what you want. Then modify it to add your own custom functionality.
You can, of course, also create a bundle from scratch. Simply create the bundle YAML file and start populating it to suit your needs.
