I installed Docker in my machine where I have Ubuntu OS. After than I installed docker, when I run
sudo docker run hello-world
All it's ok, but I want to hide the word sudo to make more short the command.
If I write the command without the word sudo
docker run hello-world
That display the following:
docker: Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.35/containers/create: dial unix /var/run/docker.sock: connect: permission denied.See 'docker run --help'.
It's happened the same when I try to make
docker-compose up
How can I resolve this?
If you want to run docker as non-root user then you need to add it to the docker group.
$ sudo groupadd docker
$ sudo usermod -aG docker $USER
$ newgrp docker
$ docker run hello-world
Reboot if still got error
$ reboot
