Building a swarm

Requirements

• 3 machines accessible via SSH key

Machine provisioning

Start by entering the roj management container

docker-compose run --rm roj

Discovery

docker-machine create -d generic --generic-ip-address ${ROJ_DISCOVERY_PUBLIC_IP} discovery

cd discovery/consul
eval $(docker-machine env discovery)
docker-machine ssh discovery sudo mkdir -p /host-volume/consul/data
docker-machine ssh discovery sudo chmod -R 777 /host-volume/consul/data

TODO: Update consul version, swarm image, describe config/env, docker install URL roj bind public private ROJ_MASTER_PUBLIC_IP

docker-compose up -d

Open consul web UI http://10.1.1.1:8500

Swarm master

:warning: Double-check your public IP with ifconfig, in the following commands the public IP is assigned to eth1

GENERIC_IP_ADDRESS=10.1.13.1 \
docker-machine create -d generic \
    --swarm-master \
    --swarm \
    --engine-label master=1 \
    --swarm-discovery consul://${ROJ_DISCOVERY_PUBLIC_IP}:8500/${ROJ_SWARM_NAME} \
    --engine-opt=cluster-store=consul://${ROJ_DISCOVERY_PUBLIC_IP}:8500/${ROJ_SWARM_NAME} \
    --engine-opt=cluster-advertise=eth1:2376 \
    ${ROJ_SWARM_NAME}-m1

:warning: After creating the swarm master you should either exit roj management container or

eval $(docker-machine env --swarm ${ROJ_SWARM_NAME}-m1)

App/worker nodes

GENERIC_IP_ADDRESS=10.1.13.22 \
docker-machine create -d generic \
    --swarm \
    --engine-label app=1 \
    --swarm-discovery consul://${ROJ_DISCOVERY_PUBLIC_IP}:8500/${ROJ_SWARM_NAME} \
    --engine-opt=cluster-store=consul://${ROJ_DISCOVERY_PUBLIC_IP}:8500/${ROJ_SWARM_NAME} \
    --engine-opt=cluster-advertise=eth1:2376 \
    ${ROJ_SWARM_NAME}-w22

You are now ready to deploy stacks with docker-compose.
