Cannot connect to Docker daemon?

[amytam01]

Note: Moved my issue here (copy pasted)

So I've ironed out some of the initial problems as mentioned by @mikeizbicki and ended up redoing the entire process and now have the correct export command in my .bashrc file. I've also made sure (again and again) that my docker files are not in bin but .local/bin. I've also followed Sam's suggestions and made sure my unit file was correct in ~/.config/systemd/user/docker.service

Now when I run systemctl --user start docker
I have no problems, but when I try to run docker run ubuntu
I get the following error:
Cannot connect to the Docker daemon at unix:///run/user/1137/docker.sock. Is the docker daemon running?
so usually I attempt systemctl --user daemon-reload
I think I got this error after moving my files from bin to .local/bin and I've reinstalled Docker at least 5 times (so maybe that's the problem?) I always assumed that my files were being rewritten each time they were moved. Thanks!

Edit: I've learned so much about docker commands and process after all of these issues, but I still can't get it to work xD

You have different error messages in this issue and in #7, so I'm not sure which one is the actual problem. Let me know if the fix I mentioned there doesn't work.

I'm going to close this issue and keep the rest of the discussion in #7 since we've already started there.
