On WSL2 (Ubuntu 20.04), I'm trying to connect to the Docker daemon that's running on Windows.
$ docker ps
Cannot connect to the Docker daemon at tcp://localhost:2375. Is the docker daemon running?
(exit code 1)
$ sudo docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
(exit code 0)
Why does it work with sudo, but not without sudo? How can I make it work without sudo?
I have done
$ sudo usermod -aG docker $USER
which ran successfully, but didn't help with the issue.
I have also restarted everything many times, which didn't help.
Weird solution for this one - but go ahead and try:
unset DOCKER_HOST
And if that works, you can make the fix permanent by going back and commenting out the "export DOCKER_HOST=tcp://localhost:2375" in your .bashrc file. I think it has something to do with how docker is configured in WSL 2 vs. WSL 1, but Docker never updated their documentation to reflect this.
