MagicMirror² is an open source modular smart mirror platform. With a growing list of installable modules, the MagicMirror² allows you to convert your hallway or bathroom mirror into your personal assistant.

Why Docker?

In some cases, you want to start the application without an actual app window. In this case, you can start MagicMirror² in server only mode by manually running node serveronly or using Docker. This will start the server, after which you can open the application in your browser of choice.

Run MagicMirror² in server only mode

After a successful Docker installation you just need to execute the following command in the shell:

docker run  -d \
    --publish 80:8080 \
    --restart always \
    --volume ~/magic_mirror/config:/opt/magic_mirror/config \
    --volume ~/magic_mirror/modules:/opt/magic_mirror/modules \
    --volume /etc/localtime:/etc/localtime:ro \
    --name magic_mirror \
    bastilimbach/docker-magicmirror

Environment variables

Environment variables can be passed to the docker container using the --env flag.

Variable	Description
`TZ`	Let the environment variable TZ reflect the time zone. Without the correct time zone the MagicMirror² calendar or other modules might show the wrong time of an event. Find you time zone here https://en.wikipedia.org/wiki/List_of_tz_database_time_zones

Volumes

Volume	Description
`/opt/magic_mirror/config`	Mount this folder to insert your own config into the docker container. If the folder is empty the container will create a default configuration which can be adapted to you likings.
`/opt/magic_mirror/modules`	Mount this folder to add your own custom modules into the docker container. If the folder is empty the container will copy the default modules from the MagicMirror² repository into the volume.
`/opt/magic_mirror/css/custom.css`	Mount this file to add your own custom css into the docker container. Important: You need to create the file before you run the container. Otherwise Docker will create a `custom.css` folder.
`/etc/localtime:/etc/localtime:ro`	Add this to syncronize the time of the host with the docker container. Important: This is for linux hosts. If you run your docker on other OS, you will need to change this.

Build arguments

Build variable	Description
`branch`	Specify a branch or tag of the MagicMirror repository which should be used for building the image. Default: `master`

Config

If you start the container without providing a custom configuration it will create a default config inside the config volume if it is empty. This config can then be adapted to your likings.

To keep passwords and API secrets out of the config file add .template as extension to the config file (config.js.template) and use shell variable syntax (${MY_API_TOKEN}) as placeholder for your secrets in the config file. Don't forget to pass the template variables as environment to the container. For example: --env MY_API_TOKEN=secret-token or in docker compose file:

    environment:
      - MY_API_TOKEN=secret-token

If you want to build the configuration by yourself be sure to set the following configuration properties accordingly:

var config = {
    address: "0.0.0.0", // Needs to be "0.0.0.0" to make MagicMirror listen on any interface.
    port: 8080, // If you change the port, be sure to also adapt the "--publish" flag in your docker run command. e.g: --publish 80:3000
    ipWhitelist: [] // This is required to allow all IP addresses to access MagicMirror. Can also be set to the docker subnet.
}

Docker compose

If docker-compose is your game, here is an example of such. It will publish the MagicMirror² server on port 8888.

version: '3'
services:
  magicmirror:
    container_name: magicmirror
    image: bastilimbach/docker-magicmirror
    restart: unless-stopped
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ~/magic_mirror/config:/opt/magic_mirror/config
      - ~/magic_mirror/modules:/opt/magic_mirror/modules
    ports:
      - 8888:8080

Remarks

Time zones

When it comes to time and time zones, MagicMirror² and the individual modules might use these differently. The device that presents the generated page must have the correct time and time zones settings as well. The MagicMirror² default clock uses the local device's time zone to render the time.

E.g: If you use a Raspberry Pi to show the generated result of the MagicMirror² docker, set the time zone on the RPi with

sudo raspi-config

and choose 'Localisation options'
