Build and run container images with Docker.
Usage
Ubuntu Docker Restart Container
- In this guide, we will demonstrate docker installation on Ubuntu 20.04 /20.10 and will also learn about docker compose installation and its usage. Prerequisites Ubuntu 20.04 / 20.10 along with ssh access.
- A minimal Ubuntu base image modified for Docker-friendliness. Baseimage-docker only consumes 8.3 MB RAM and is much more powerful than Busybox or Alpine. Baseimage-docker is a special Docker image that is configured for correct use within Docker containers. It is Ubuntu, plus: Modifications for Docker-friendliness.
- This build can only access files in the home directory. So Dockerfiles and all other files used in commands like
docker build,docker saveanddocker loadneed 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
