Running The Examples

There are two ways to run docker, daemon mode and standalone mode.

When you run the docker command it will first check if there is a docker daemon running in the background it can connect to.

• If it exists it will use that daemon to run all of the commands.
• If it does not exist docker will run in standalone mode (docker will exit after each command).

Docker needs to be run from a privileged account (root).

1. The most common (and recommended) way is to run a docker daemon as root in the background, and then connect to it from the docker client from any account.

   # starting docker daemon in the background
   sudo docker -d &
   
   # now you can run docker commands from any account.
   docker <command>

2. Standalone: You need to run every command as root, or using sudo

   sudo docker <command>
