Docker is a popular tool for running application containers. Docker is supported on vpsAdminOS and works out-of-the-box, but with several known issues.
The latest Docker version can be installed by following the manual for your distribution, e.g. https://docs.docker.com/install/linux/docker-ce/ubuntu/.
- Docker in Docker (DinD) does not work, it tries to mount
/sys/fs/security, which is not possible in an unprivileged container.
