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 includecloud-init
are provided. Seecloud-init

server). It does, however, provide desktop variants of current Ubuntu releases.See

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 topublic
.- 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.
