We’ll create a similar environment as we did in the previous chapter. We'll have three nodes which will form a Swarm cluster.
All the commands from this chapter are available in the 03-networking.sh (https://gist.github.com/vfarcic/fd7d7e04e1133fc3c90084c4c1a919fe) Gist.
By this time, you already know how to set up a cluster so we'll skip the explanation and just do it:
for i in123; do
docker-machine create -d virtualbox node-$i
done
eval $(docker-machine env node-1)
docker swarm init \
--advertise-addr $(docker-machine ip node-1)
TOKEN=$(docker swarm join-token -q worker)
for i in23; do
eval $(docker-machine env node-$i)
docker swarm join \
--token $TOKEN \
--advertise-addr $(docker-machine ip node-$i) \
$(docker-machine ip node-1):2377
done
eval $(docker-machine env node-1)
docker node lsThe output of the last command node ls is as follows (IDs were removed for brevity):
HOSTNAME STATUS AVAILABILITY MANAGER STATUS
node-2 Ready Active
