I'm not sure how different distro's handle the Docker installation, but here in my office we use RHEL7. When installing Docker, the daemon doesn't start automatically, we have to manually enable and start it. This may explain why you think you need to reboot. It may just be as simple as starting the daemon instead. For me on RHEL7, I just run this:
Then I'm set (well there's much more we do, but in this context that's it). But again, I'm not familiar with how other distro's handle it, so some research may be needed for your distro.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
