Common Docker parameters explained

-it
- Execute using "interactive tty", i.e. execute the command and hold the session until the command ends (with possible keyboard input).
-p 8080:3000
- Bind the port 3000 from the container to the local network interface on port 8080. The port that is closer to the container image name (see below) is the one that refers to the container port, the other one refers to the local network port.
-d
- Run the container as daemon (instead of interactively with -it).
-v /opt/postgres/data:/var/lib/postgresql/data
- Attach a local volume to a container for data persistance. Follow the same logic as with the ports to know which one refers to the container and which one to the local filesystem.
