How to configure the LXD server

See Server configuration for all configuration options that are available for the LXD server.

If the LXD server is part of a cluster, some of the options apply to the cluster, while others apply only to the local server, thus the cluster member. In the Server configuration option tables, options that apply to the cluster are marked with a global scope, while options that apply to the local server are marked with a local scope.

Configure server options

CLIAPIUI

You can configure a server option with the following command:

lxc config set <key> <value>

For example, to allow remote access to the LXD server on port 8443, enter the following command:

lxc config set core.https\_address :8443

In a cluster setup, to configure a server option for a cluster member only, add the --target flag. For example, to configure where to store image tarballs on a specific cluster member, enter a command similar to the following:

lxc config set storage.images\_volume my-pool/my-volume --target member02

Send a PATCH request to the /1.0 endpoint to update one or more server options:

lxc query --request PATCH /1.0 --data '{
  "config": {
    "<key>": "<value>",
    "<key>": "<value>"
  }
}'

For example, to allow remote access to the LXD server on port 8443, send the following request:

lxc query --request PATCH /1.0 --data '{
  "config": {
    "core.https\_address": ":8443"
  }
}'

In a cluster setup, to configure a server option for a cluster member only, add the target parameter to the query. For example, to configure where to store image tarballs on a specific cluster member, send a request similar to the following:

lxc query --request PATCH /1.0?target=member02 --data '{
  "config": {
    "storage.images\_volume": "my-pool/my-volume"
  }
}'

See PATCH /1.0 for more information.

Go to Settings to configure the server options.

In a cluster setup, server options that apply to the local server are updated only for the server on which you are accessing the UI. For example, if you access the UI on server1 and update the location for storing image tarballs (storage.images_volume, which has a local scope) from local/pool1 to local/pool2, storage.images_volume will still be configured to local/pool1 on server2.

Display the server configuration

CLIAPIUI

To display the current server configuration, enter the following command:

lxc config show

In a cluster setup, to show the local configuration for a specific cluster member, add the --target flag.

Send a GET request to the /1.0 endpoint to display the current server environment and configuration:

lxc query --request GET /1.0

In a cluster setup, to show the local environment and configuration for a specific cluster member, add the target parameter to the query:

lxc query --request GET /1.0?target=<cluster\_member>

See GET /1.0 for more information.

Go to Settings to view the current server configuration.

In a cluster setup, this view shows the local configuration for the cluster member on which you are accessing the UI.

Edit the full server configuration

CLIAPIUI

To edit the full server configuration as a YAML file, enter the following command:

lxc config edit

In a cluster setup, to edit the local configuration for a specific cluster member, add the --target flag.

To update the full server configuration, send a PUT request to the /1.0 endpoint:

lxc query --request PUT /1.0 --data '<server\_configuration>'

In a cluster setup, to update the full server configuration for a specific cluster member, add the target parameter to the query:

lxc query --request PUT /1.0?target=<cluster\_member> '<server\_configuration>'

See PUT /1.0 for more information.

The UI does not currently support editing the full server configuration.
