docker-py : PermissionError(13)

Question

While I was running

>>> import docker
>>> client = docker.from_env()
>>> client.containers.list()

I encountered the following error

requests.exceptions.ConnectionError: ('Connection aborted.', PermissionError(13, 'Permission denied'))

I think it is because docker-py is not able to get access of the docker daemon. So how do I fix this?

Answer 1

According to Docker docs you should create a group and attach your user to that group.

Create Group

sudo groupadd docker

Attach User to Group

sudo usermod -aG docker $USER

Reload

su -s ${USER}

podman system service tcp:localhost:8080 --time=0 &
