Installation on Docker

Installation with Docker is straightforward. Adjust the following command so that /path/to/your/config/ points at the folder where you want to store your config and run it:

Linux

$ docker run -d --name="home-assistant" -v /path/to/your/config:/config -v /etc/localtime:/etc/localtime:ro --net=host homeassistant/home-assistant

macOS

When using boot2docker on macOS you are unable to map the local time to your Docker container. Use -e "TZ=America/Los_Angeles" instead of -v /etc/localtime:/etc/localtime:ro. Replace “America/Los_Angeles” with your timezone.

Additionally, if your expectation is that you will be able to browse directly to http://localhost:8123 on your macOS host, then you will also need to replace the --net=host switch with -p 8123:8123. This is currently the only way to forward ports on to your actual host (macOS) machine instead of the virtual machine inside xhyve. More detail on this can be found in the docker forums.

$ docker run -d --name="home-assistant" -v /path/to/your/config:/config -e "TZ=America/Los_Angeles" -p 8123:8123 homeassistant/home-assistant

Windows

When running Home Assistant in Docker on Windows, you may have some difficulty getting ports to map for routing (since the --net=host switch actually applies to the hypervisor’s network interface). To get around this, you will need to add port proxy ipv4 rules to your local Windows machine, like so (Replacing ‘192.168.1.10’ with whatever your Windows IP is, and ‘10.0.50.2’ with whatever your Docker container’s IP is):

netsh interface portproxy add v4tov4 listenaddress=192.168.1.10 listenport=8123 connectaddress=10.0.50.2 connectport=8123
netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=8123 connectaddress=10.0.50.2 connectport=8123

This will let you access your Home Assistant portal from http://localhost:8123, and if you forward port 8123 on your router to your machine IP, the traffic will be forwarded on through to the docker container.

Synology NAS

As Synology within DSM now supports Docker (with a neat UI), you can simply install Home Assistant using docker without the need for command-line. For details about the package (including compatability-information, if your NAS is supported), see https://www.synology.com/en-us/dsm/app_packages/Docker

The steps would be:

Install “Docker” package on your Synology NAS
Launch Docker-app and move to “Registry”-section
Find “homeassistant/home-assistant” with registry and click on “Download”
Wait for some time until your NAS has pulled the image
Move to the “Image”-section of the Docker-app
Click on “Launch”
Choose a container-name you want (e.g. “homeassistant”)
Click on “Advanced Settings”
Set “Enable auto-restart” if you like
Within “Volume” click on “Add Folder” and choose either an existing folder or add a new folder. The “mount point” has to be “/config”, so that Home Assistant will use it for the configs and logs.
Within “Network” select “Use same network as Docker Host”
Confirm the “Advanced Settings”
Click on “Next” and then “Apply”
Your Home Assistant within Docker should now run

Remark: to update your Home Assistant on your Docker within Synology NAS, you just have to do the following:

Go to the Docker-app and move to “Image”-section
Download the “homeassistant/home-assistant” image - don’t care, that it is already there
wait until the system-message/-notification comes up, that the download is finished (there is no progress bar)
Move to “Container”-section
Stop your container if it’s running
Right-click on it and select “Action”->”Clear”. You won’t loose any data, as all files are stored in your config-directory
Start the container again - it will then boot up with the new Home Assistant image

Restart

This will launch Home Assistant and serve the web interface from port 8123 on your Docker host.

If you change the configuration you have to restart the server. To do that you have 2 options.

You can go to the service developer tools, select the service homeassistant/restart and click “Call Service”.
Or you can restart it from an terminal by running docker restart home-assistant
