Configuration of the containers can also be overridden using `glance.yml`. Containers are specified by their container names, these will take preference over any docker labels that are set:
|
||||
Alternatively, you can also define the values within your `glance.yml` via the `containers` property, where the key is the container name and each value is the same as the labels but without the "glance." prefix:

##### `hide-by-default`
|
||||
Whether to hide the containers by default. If set to `true` you'll have to manually add a `glance.hide: false` label to each container you want to display. By default all containers will be shown and if you want to hide a specific container you can add a `glance.hide: true` label.
|
||||
|
||||
##### `format-container-names`
|
||||
When set to `true`, automatically converts container names such as `container_name_1` into `Container Name 1`.
|
||||
|
||||
##### `sock-path`
|
||||
The path to the Docker socket.
