I have installed docker as described here. I use Ubuntu Trusty 14.04 (LTS) (64-bit). Everything during installation was well. Also command
$ sudo docker run -i -t ubuntu /bin/bash completes well (after I typed "exit" in opened console. But when I tryin to do something else I get "permission denied". For example:
`$ sudo docker run -d -P training/webapp python app.py`
Post http:///var/run/docker.sock/v1.12/containers/create: dial unix /var/run/docker.sock: permission denied
` docker info`
Get http:///var/run/docker.sock/v1.12/info: dial unix /var/run/docker.sock: permission denied
How to solve this? I googled about the problem but I can not find a solution for my case.
