Usage

  • This build can only access files in the home directory. So Dockerfiles and all other files used in commands like docker build, docker save and docker load need to be in $HOME.
  • You can change the configuration of this build by modifying the files in /var/snap/docker/current/.
  • Additional certificates used by the Docker daemon to authenticate with registries need to be added in /var/snap/docker/common/etc/certs.d (instead of /etc/docker/certs.d).

Running Docker as normal user

By default, Docker is only accessible with root privileges (sudo). If you want to use docker as a regular user, you need to add your user to the docker group.

Warning: if you add your user to the docker group, it will have similar power as the root user. For details on how this impacts security in your system, see https://docs.docker.com/engine/security/#docker-daemon-attack-surface
