[docker] Basic command

  1. Create the docker file
  • docker image ls
    -> should be able to see the image
  • Docker COMMIT command (easy way)
    → inside docker container, you download stuff and then you can commit the container as it is to be an image
    docker commit <containerID> 1junechung/newcustomimage
docker run --name container1 my_first_image(actual image name) If docker has permission issues (only root allowed and normal user is not allowed)sudo usermod -aG docker $(whoami)If this doesn't work as well -> 
It means no privilege for creating new sockets in docker
sudo chmod 666 /var/run/docker.sock
