# Remote image servers

The `lxc` CLI command comes pre-configured with the following default remote image servers:

`images:`

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

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

`ubuntu:`

  This server 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 server 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 server 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 server 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.

## Remote server types

LXD supports the following types of remote image servers:

Simple streams servers

  Pure image servers that use the simple streams format. The default image servers are simple streams servers.

Public LXD servers

  LXD servers that are used solely to serve images and do not run instances themselves.

  To make a LXD server publicly available over the network on port 8443, set the `core.https_address` configuration option to `:8443` and do not configure any authentication methods (see How to expose LXD to the network for more information). Then set the images that you want to share to `public`.

LXD servers

  Regular LXD servers that you can manage over a network, and that can also be used as image servers.

  For security reasons, you should restrict the access to the remote API and configure an authentication method to control access. See How to expose LXD to the network and Remote API authentication for more information.
