Presets

Concierge ships with several built-in presets that cover common charm development setups. Choose one with -p / --preset. For example:

sudo concierge prepare -p dev

Preset	Included
crafts	lxd, snapcraft, charmcraft, rockcraft
dev	juju, k8s, lxd, snapcraft, charmcraft, rockcraft, jhack, astral-uv
k8s	juju, k8s, lxd, rockcraft, charmcraft
microk8s	juju, microk8s, lxd, rockcraft, charmcraft
machine	juju, lxd, snapcraft, charmcraft

In the k8s and microk8s presets, LXD is installed but not bootstrapped — it is present only so Charmcraft can use it as a build backend.

To adapt one of these presets into your own config, see How to write a custom config.
