Linux
The recommended way to install Charmcraft on Linux is from the stable channel via snap:
sudo snap install charmcraft --classic
There are multiple channels other than stable. See the full list with snap info charmcraft.
We recommend either latest/stable or latest/candidate for everyday charming. With the snap you will always be up to date as Charmhub services and APIs evolve. Charmcraft supports Kubernetes operator development.
In Linux Charmcraft defaults to LXD to build the charms in a container matching the target base(s) (Multipass can also be used). Charmcraft will offer to install LXD if required, but here are steps to set it up manually:
$ sudo snap install lxd
$ sudo adduser $USER lxd
$ newgrp lxd
$ lxd init --auto

Isolated environment
One way to install Charmcraft is via Multipass. This is a good way to install it on any platform, as it will give you an isolated development environment.
First, install Multipass.
Second, use Multipass to provision a virtual machine. The following command will launch a fresh new VM with 4 cores, 8GB RAM and a 20GB disk and the name ācharm-devā:
$ multipass launch --cpus 4 --memory 8G --disk 20G --name charm-dev
Last, open a shell in your new Ubuntu virtual machine, and install Charmcraft there:
$ multipass shell charm-dev
...
ubuntu@charm-dev:~$ sudo snap install charmcraft --classic
charmcraft 2.2.0 from Canonicalā installed
Thatās it. You can now start typing in Charmcraft commands.
