普通用户没有docker,非root用户如何安装docker？

I am using a CentOS 6.9 system of High performance computation platform and I wanna use docker with non-root user. Is there a method that I can build docker from source and do not need root privilege?

This shouldn't be possible as it would be a major security concern.

When docker is installed on a machine, users with docker access (not necessarily root) can start containers. In particular, they can start containers in priviliged mode, giving the container access to all host devices.

More importantly, A user with access to docker can mount directories owned exclusively by machine root. Since by default, a root user inside the container will have access to mounted root-owned directories inside the container, this will allow any Docker container started by a non-root user to access critical machine stuff.

Therefore, the sequence of having a non-root user install Docker and start containers should not be allowed as it can compromise the whole machine.

Check this explicit comment from one of the docker maintainers.
