bootstrap docker swarm

docker-swarm-install.md

i like using docker swarm for home labs

assumes you installed docker like this

Initialize Swarm on first docker node (management node)

sudo docker swarm init

it will produced output something like this

docker swarm join --token <some-very-long-token> 192.168.1.41:2377

make sure you copy and keep this command as you will run it on all your other nodes (the IP address should match the IP of this management node, if it doesn't you need to troubleshoot networking).

Initialize worker nodes

On each worker node run the command from the last step

sudo docker swarm join --token <some-very-long-token> 192.168.1.41:2377

the IP is the IP of the management node and doesn't need to be changed as you run this on each node.

thats it you should now have a fully functioning swarm

since creating this gist i figured out how to run portainer as a swarm service - as such i made every node a manager node too.

quick note there is a typo in the initialize docker command it should me

sudo docker swarm init

sudo docker swarm init

+1

maybe consider set all node as manager: https://docs.docker.com/engine/swarm/admin_guide/#add-manager-nodes-for-fault-tolerance

lol, yeah did that a long time ago, never bothered documenting it
it is required to have portainer become a swarm app (which one should never do of course ;-) )
