  • Services (job queues, cache servers, search engines, etc.)

  • Deployment instructions

Try it:

Create swarm cluster with 3 nodes

./docker-swarm-compose.sh -n 3

Make sure you are on master node

docker-machine ls you should see something like this:

master * (swarm) virtualbox Running tcp://192.168.99.140:2376 master (master) v1.12.1

notice the * (swarm) it means everything is ok

Run services

docker-compose up -d

Create and migrate DB

docker-compose exec web rake db:create db:migrate

Scale web service

docker-compose scale web=3

Check logs

docker-compose logs -f

Add a few nodes to swarm cluster

./docker-swarm-compose.sh -i 4 -n 1 -s -i means first index e.i. -i 4 -n 3 creates node4, node5, node6 and node7 (4 + 3) -s skip master. does not create master node - it already exists
