Learn how to install Mycroft for Docker either from a Docker Hub install, or by building the image. Many thanks to Brian Hopkins (@btotharye) for this documentation.

Mycroft is available for Docker. You have two options for a Docker installation:
Build Image from source  
Pull Image from Docker Hub
Prerequisites
This documentation assumes the following:
You have already installed Docker on your machine based on the operating system you are running.
Getting Started
Installing from Docker Hub
The Mycroft for Docker image is updated on dockerhub and you can install it by running the command below:
1
docker pull mycroftai/docker-mycroft
Copied!
Then follow the instructions below for running Mycroft for Docker.
Installing via building the Docker image
it pull this repository.
1
git clone https://github.com/MycroftAI/docker-mycroft.git
Copied!
Build the Docker image in the directory that you have checked out.
1
docker build -t mycroft .
Copied!
Follow the instructions for running Mycroft for Docker below to continue.
Running Mycroft for Docker
To prevent having to register your instance with home.mycroft.ai every time the container is started, and to have persistent data, you can map a local directory into the container. Just replace the directory_on_local_machine with the path you want the container mapped to on your local machine (eg. /home/user/mycroft).
Sounds can be played in the Docker container using pulseaudio, without modifying any config files
Set PULSE_SERVER env variable  
Share pulseaudio's cookie​
Run the following to start up Mycroft for Docker:
_NOTE: You don't need the -e PULSE_SERVER or any of the other pulse related variables if you only want to use text via a websocket to mycroft for example using this container.
1
docker run -d  
2
-v directory_on_local_machine:/root/.mycroft  
3
--device /dev/snd  
4
-e PULSE_SERVER=unix:${XDG_RUNTIME_DIR}/pulse/native  
5
-v ${XDG_RUNTIME_DIR}/pulse/native:${XDG_RUNTIME_DIR}/pulse/native  
6
-v ~/.config/pulse/cookie:/root/.config/pulse/cookie  
7
-p 8181:8181  
8
--name mycroft mycroftai/docker-mycroft
Copied!
Confirm via docker ps that your container is up and serving port 8181:
1
docker ps  
2
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES  
3
692219e23bf2 mycroft "/mycroft/ai/mycro..." 3 seconds ago Up 1 second 0.0.0.0:8181->8181/tcp mycroft
Copied!
You should now have a running instance of Mycroft for Docker that you can interact with via the command line.
Pairing Mycroft for Docker
After the container has been started you can watch the logs and look for the line that says "Pairing Code" and use this to pair at https://home.mycroft.ai.
You can view the logs with:
1
docker logs -f mycroft
Copied!
Interacting With Mycroft on Docker
Accessing Mycroft Logs
At any time you can watch the logs simply by running the bellow command:
1
docker logs -f mycroft
Copied!
You can exit out of this docker log command by hitting Ctrl + C. The --follow turns it into a real tail instead of a cat of the log.
CLI Access
Accessing Mycroft CLI
You can interact with the CLI of the container by running the following command. This will connect you to the running container via bash:
1
docker exec -it mycroft /bin/bash
Copied!
Once in the container you can do ./start-mycroft.sh cli to get a interactive CLI to interact with Mycroft for Docker if needed.
You can type Ctrl + C to exit the cli.
Installing Skills on Docker Mycroft
You can install Skills into the container by running the following:
1
docker exec -it mycroft /opt/mycroft/msm/msm install github_url
Copied!
So to install the Hello World Skill:
1
docker exec -it mycroft /opt/mycroft/msm/msm install https://github.com/MycroftAI/skill-hello-world
Copied!
Removing Skills on Docker Mycroft
You can also uninstall a Skill using MSM with:
1
docker exec -it mycroft /opt/mycroft/msm/msm remove skill-hello-world
Copied!
Troubleshooting
Text-to-speech not working
There have been reports that mimic may not be properly added to the PATH. Restarting Mycroft within the Docker container can resolve this.
