¶Configure snaps

Certain snaps, such as those providing a background service, expose configuration options that can be viewed and changed.

The commands for viewing and changing these configuration options are snap get, snap set and snap unset.

For example, to see the configuration options exposed by an installed snap, enter snap get :

$ sudo snap get nextcloud
Key        Value
mode       production
nextcloud  {...}
php        {...}
ports      {...}
private    {...}

The {...} in the output indicates that there are further options beneath the current key name level.

:information_source: If there are no configuration options, you will see error: snap has no configuration.

$ sudo snap get vls
error: snap "vls" has no configuration

• To explore configuration options, append the key name to the get command:

$ sudo  snap get nextcloud ports
Key          Value
ports.http   45101
ports.https  443

$ sudo snap get -d nextcloud 
{
        "http": {
                "compression": false,
                "notify-push-reverse-proxy": false
        },
        "mode": "production",
        "nextcloud": {
                "cron-interval": "5m"
        },
        "php": {
                "memory-limit": "512M"
        },
        "ports": {
                "http": 45101,
                "https": 443
        },
        "private": {
                "http": {
                        "compression": false,
                        "notify-push-reverse-proxy": false
                },
                "mode": "production",
                "nextcloud": {
                        "cron-interval": "5m"
                },
                "php": {
                        "memory-limit": "512M"
                },
                "ports": {
                        "http": 45101,
                        "https": 443
                },
                "snap": {
                        "version": "27.1.8snap1"
                }
