One of the first things you want to do if you’ve just installed Raspbian on your Pi is to change the hostname. You can change your hostname by following these steps.

Steps

You can use the hostnamectl set-hostname [name] command, but that does not update /etc/hosts and causes issues with Docker and other networking services. I prefer to update /etc/hostname and /etc/hosts manually.

1. Change hostname

sudo nano /etc/hostname

Change raspberrypi to your desired hostname. Hit CTRL+O and then ENTER to save. Hit CTRL+X to exit.

How to install Docker

With one of the latest releases of Docker, they added official support for Raspbian. You can now easily install Docker on your Raspberry Pi with one simple command.
