LXC connect to remote LXD | Guide

Remote servers are a concept in the LXD command-line client.

By default, the command-line client interacts with the local LXD daemon. However, we can add other servers or clusters to interact with.

Furthermore, we can also add a full LXD server as a remote server to our client. In this case, we can interact with the remote server in the same way as with our local daemon.

Also, to add an LXD server as a remote server, the server’s API has to be exposed. In other words, it’s core.https_address server configuration option must be set.

When we add the server, we must authenticate with it for Remote API authentication.

Furthermore, we can see configured remote servers with this command:

lxc remote list

Remote servers that use the simple stream format are pure image servers.

Servers that use the LXD format are LXD servers. They serve solely as image servers or may offer some images in addition to serving as regular LXD servers.

We can add a LXD server as a remote with this command:

lxc remote add remote_name IP|FQDN|URL [flags]

Some authentication methods require specific flags.

For example, we can enter the following command to add a remote through an IP address:

lxc remote add my-remote 192.0.1.11

Then, we have to confirm the remote server fingerprint. After that, we have to enter the password or token, depending on the authentication method used by the remote.

<h4How to select a Default Remote

The LXD command-line client is pre-configured with the local remote, which is the local LXD daemon.
We can select a different remote as the default remote with this command:

lxc remote switch remote_name

Additionally, we can see which server is configured as the default remote with this command:

lxc remote get-default

How to configure a Global Remote

We can easily configure remotes on a global. Furthermore, these remotes are available for every user of the LXD server for which you add the configuration.

Users can override these system remotes leading to the remote and its certificates getting copied to the user configuration.

We can configure a global remote by editing the config.yml file that is located at:

• the directory specified by LXD_GLOBAL_CONF
• /var/snap/lxd/common/global-conf/
• /etc/lxd/

Certificates for the remotes have to be stored in the servercerts directory in the same location and match the remote name.
