I still had a bunch of Raspberry Pi2 not doing anything for a while.
So I started a new Project to run a little cluster of Raspberry’s
my goal is to run most of my docker containers I use on a daily base of the Pi.
we start with a fresh rasbian-lite image.
First we update all the Pi’s in the cluster:
sudo apt update && sudo apt dist-upgrade -y
sudo apt-get install apt-transport-https ca-certificates software-properties-common -y
curl -fsSL get.docker.com -o get-docker.sh && sh get-docker.sh
sudo usermod -aG docker pi
sudo curl https://download.docker.com/linux/raspbian/gpg
sudo nano /etc/apt/sources.list
Add the following line and save:
deb https://download.docker.com/linux/raspbian/ stretch stable
Update and start the services:
sudo apt-get update
sudo apt-get upgrade
systemctl start docker.service
systemctl enable docker.service
Create the swarm on 1 node:
docker swarm init
on the rest of the node join the swarm.
Have fun 😉
