I discovered this solution on AskUbuntu after encountering the problem. How to set up Docker to run without using sudo all the time This can be fixed, but it’ll take a few more lines. One small issue, though, is that you might experience difficulty running Docker commands without sudo. This means that the commands will run one after the other, but can be typed on the same line. Now you have Docker installed, and the installation only took two lines.Īs you just saw, the two commands above are chained together using the ‘&’ operator. The two commands can be chained together to form a statement like: curl -fsSL -o get-docker.sh & sh get-docker.sh The first command will be consuming this URL, looking for a file called get-docker.sh. Installing Docker can be handled by a bash script which will automate the entire installation. Yes, you heard right! With just two lines you can load and install Docker.
