example docker forwarding from host requires elevated permissions
teddy-codes opened this issue · comments
When going through the docker example in the docs, I am unable to set the user permissions properly. I have tried RUN sudo usermod -a -G docker $(whoami), but... that failed. Not sure what I could be doing wrong. Any insight would be great.
Hi,
I get permission errors while doing even a docker ps.
I followed the instructions from https://sail.dev/docs/guides/docker-in-docker/ to install docker, btw.
I also noticed that the user user does not belong to the docker group. Not really sure what is the right procedure if you install the docker client only, like I did.
Nonetheless I tried to add the user to the docker group, from inside my .sail/Dockerfile with:
sudo groupadd docker
sudo usermod -aG docker user
as per: https://docs.docker.com/install/linux/linux-postinstall/
But still, although the user now belongs to the docker group:
user@sgo:~/sgo$ groups
user docker
still I cannot access Docker, when running the docker, getting a:
user@sgo:~/sgo$ docker ps
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/containers/json: dial unix /var/run/docker.sock: connect: permission denied
from the VS Code terminal.
This prevents me starting some docker-compose files that I need to run.
If you do this, then you are unable to use docker on the host machine.
Edit:
Until a restart
Why is that? I have no issues using docker in the host machine.
