SSH to a docker container

Question

I'm new to docker and I don't manage to connect to a container.

If I understand properly I have to connect to SSH to my actual host then use this :

docker exec -it pihole-pihole1(name_of_the_container) command

but then when I do this :

docker exec -it pihole-pihole1 sudo nano /etc/pihole/adlists.list

I have this error :

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.29/containers/pihole-pihole1/exec: dial unix /var/run/docker.sock: connect: permission denied

How should I proceed ?

Answer 1

You need to add your user to Docker group on the host machine:

sudo usermod -aG docker <username>

Logout, login again, it should work. Otherwise you need to insert sudo before all of your docker commands.
