5.15. Images and containers

LXD is image based. When you create your first container, you will generally do so using an existing image. LXD comes pre-configured with three default image remotes:

• ubuntu: This is a simplestreams-based44 remote serving released ubuntu cloud images.

• ubuntu-daily: This is another simplestreams based remote which serves 'daily' ubuntu cloud images. These provide quicker but potentially less stable images.

• images: This is a remote publishing best-effort container images for many distributions, created using community-provided build scripts.

To view the images available on one of these servers, you can use:

lxc image list ubuntu:

Most of the images are known by several aliases for easier reference. To see the full list of aliases, you can use

lxc image alias list images:

Any alias or image fingerprint can be used to specify how to create the new container. For instance, to create an amd64 Ubuntu 14.04 container, some options are:

lxc launch ubuntu:14.04 trusty1 lxc launch ubuntu:trusty trusty1

lxc launch ubuntu:trusty/amd64 trusty1 lxc launch ubuntu:lts trusty1
