Overview

This PR adds support for interim and devel Ubuntu releases with LXD.

Broken into 6 separate commits to speed up review time.

Details

Previously, craft-providers maintained a list of valid LXD images with a simple enum. Now, the remotes.py module has a new dataclass called RemoteImage and a dictionary of valid RemoteImages to track what images are supported.

It is designed in such a way that users can add custom remotes and we'll be able to add support for other bases (like a centos base) without breaking changes.

Usage

For applications using the LxdProvider class (snapcraft, charmcraft, and rockcraft), there are no changes in behavior or usage. You can simply pass in the new release names:

class BuilddBaseAlias(enum.Enum):
    XENIAL = "16.04"
    BIONIC = "18.04"
    FOCAL = "20.04"
    JAMMY = "22.04"
    KINETIC = "22.10"
    LUNAR = "23.04"

For other applications (lpcraft 👀), you'll need to use the replace the old configure_buildd_image_remote() function with the new get_remote_image() function.

Note - the old function configure_build_image_remote() still exists and its behavior is unchanged, except for a deprecation notice.

Example usage

remote_image = lxd.get_remote_image(BuilddBaseAlias.KINETIC.value)

base_configuration = bases.BuilddBase(alias=BuildBaseAlias.KINETIC)

instance = lxd.launch(
    name="my-instance",
    base_configuration=base_configuration,
    image_name=remote_image.image_name,
    image_remote=remote_image.remote_name,
)
