Built-in image registries

LXD downloads images through image registries. Every LXD server comes pre-configured with the following built-in image registries, which point to the default public image sources:

images

This registry provides unofficial images for a variety of Linux distributions. The images are built to be compact and minimal, and therefore the default image variants do not include cloud-init. Where possible, /cloud variants that include cloud-init are provided. See cloud-init support in images.

This registry does not provide official Ubuntu images (for those, use the ubuntu registry). It does, however, provide desktop variants of current Ubuntu releases.

See images.lxd.canonical.com for an overview of available images.

ubuntu

This registry provides official stable Ubuntu images. All images are cloud images, which means that they include both cloud-init and the lxd-agent.

See cloud-images.ubuntu.com/releases for an overview of available images.

ubuntu-daily

This registry provides official daily Ubuntu images. All images are cloud images, which means that they include both cloud-init and the lxd-agent.

See cloud-images.ubuntu.com/daily for an overview of available images.

ubuntu-minimal

This registry provides official Ubuntu Minimal images. All images are cloud images, which means that they include both cloud-init and the lxd-agent.

See cloud-images.ubuntu.com/minimal/releases for an overview of available images.

ubuntu-minimal-daily

This registry provides official daily Ubuntu Minimal images. All images are cloud images, which means that they include both cloud-init and the lxd-agent.

See cloud-images.ubuntu.com/minimal/daily for an overview of available images.

The built-in registries all use the simplestreams protocol. They are marked as built-in and cannot be renamed, reconfigured, or deleted. To access images from additional sources, create your own image registries.
