Create swarm

docker-machine create -d virtualbox ops1
docker-machine create -d virtualbox ops2
docker-machine create -d virtualbox ops3

eval $(docker-machine env ops1)
docker swarm init --advertise-addr 192.168.99.100
Swarm initialized: current node (d07w3nifvzwb5dmfykw8d0p88) is now a manager.
To add a worker to this swarm, run the following command:

    docker swarm join \
    --token SWMTKN-1-5637fsoo3iavhazcwywhldxi5jeuw61i7nvfrybgxherazphjn-3h6tyc12kzy960p66qz8hds9v \
    192.168.99.100:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

eval $(docker-machine env ops2)
docker swarm join \
--token SWMTKN-1-5637fsoo3iavhazcwywhldxi5jeuw61i7nvfrybgxherazphjn-3h6tyc12kzy960p66qz8hds9v \
192.168.99.100:2377

eval $(docker-machine env ops3)
docker swarm join \
--token SWMTKN-1-5637fsoo3iavhazcwywhldxi5jeuw61i7nvfrybgxherazphjn-3h6tyc12kzy960p66qz8hds9v \

Create network

eval $(docker-machine env ops1)
docker network create -d overlay dockercoins

docker service create --name rng --network dockercoins --mode global jpetazzo/dockercoins_rng:1465439244

Debug overlay network

docker service create --network dockercoins \
--name debug --mode global \
alpine sleep 1000000000

Rolling update

eval $(docker-machine env ops1)

docker tag jpetazzo/dockercoins_rng:1465439244 ballot/dockercoins_rng:latest

watch -n1 "docker service ps rng | grep -v Shutdown.*Shutdown"

docker service update rng --image ballot/dockercoins_rng:latest
