Docker on Qubes

Since this page is apparently the top result on google, Heres a link to how to do it.

https://martingladdish.co.uk/technology/setting-up-docker-under-qubesos/

That page has more detail, but here are the instructions in case its down.

1. Install docker engine, following the instruction on https://www.docker.com. NOT DESKTOP as that wont work in Qubes (unless you enable nested virtualization)
2. Make the below /etc/docker/daemon.json
3. Add "dockerd &" to your appvms (NOT TEMPLATE) /rw/config/rc.local

/etc/docker/daemon.json

{
    "data-root": "/home/user/docker",
    "group": "user"
}

Tried this with the debian-11 template on August 23, 2023. Martin did this with fedora-33 in 2021.

If you have trouble, you can ask for help at https://forum.qubes-os.org/

To do this in Qubes-OS 3.x, look at the history of this page.

I agree with @sw4k. A few corrections though.

For debian, the docker package from https://docs.docker.com/engine/install/debian/#install-using-the-repository is called docker-ce.
They recommend installing these sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
In Debian the services are enabled by default when you install them (in Fedora they are disabled), so you will have to disable them in the template after install, if you want it only enabled through qvm-service.
You don't need to enable containerd, since the docker service depends on it.
