Docker inside a Linux VM?

[maxacarvalho]

Hi, is there a way to install Docker inside a Linux VM?

[kdrag0n]

You can just install it like you normally would. For example, in a Ubuntu machine:

sudo apt install docker.io
# make it work without root
sudo useradd -aG docker $USER
# then exit the shell session and start a new one
docker ps

The plan is for Docker to be set up automatically in machines in the future. See #269 for more info about that.

Yeah, that works fine for arm64 machines but not for amd64 ones. Is that a known issue/limitation?
Here's what I get back after trying to run an image:

You can fix that specific error by upgrading the Docker engine to 24.x.x in the machine.

However, you'll get a different error on v24, which appears to be related to emulator limitations: #301

It needs more investigation though. We may be able to fix or work around the issue.

[maxacarvalho]

Yeah, I got the same error.

Works fine for me with official install instructions:
https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository
https://docs.docker.com/engine/install/linux-postinstall/#manage-docker-as-a-non-root-user

sudo useradd -aG docker $USER
sudo usermod -aG docker $USER
