Setting up cluster on AWS

Remember that you must push all images declared in docker-stack.yml to docker hub.

  1. Use Cloudformation Docker Swarm mode template to set up environment. I've used 1 manager and 1 worker. I've named my env "DockerSwarmGoDemo".

  2. Make sure you can SSH into the created manager node. May need to disable source check in EC2 Admin GUI and chmod 400 KEYFILE and/or open up Inbound rules in the ELBs.

  3. SSH into manager node. E.g. ssh -i ~/.ssh/MYKEY.pem [email protected]

  4. Run:

    docker swarm init

Make sure you save the TOKEN stuff such as:

docker swarm join --token SWMTKN-1-2x3u57q7gs8s3or6on1cz4i3t21hf3o21dse7dbt71yhz0oryg-2bzpoa4n2694notj8cubjq3li 172.31.11.84:2377

  1. SSH into the other node and run:

    docker swarm join --token SWMTKN-1-2x3u57q7gs8s3or6on1cz4i3t21hf3o21dse7dbt71yhz0oryg-2bzpoa4n2694notj8cubjq3li 172.31.11.84:2377

  2. Upload stack file:

    scp -i ~/.ssh/MYKEY.pem docker-stack.yml [email protected]:/home/docker

  3. Deploy stack in manager node:

    docker stack deploy -c docker-stack.yml DockerSwarmGoDemo Creating network DockerSwarmGoDemo_frontend Creating network DockerSwarmGoDemo_default Creating network DockerSwarmGoDemo_backend Creating service DockerSwarmGoDemo_rabbitmq Creating service DockerSwarmGoDemo_configserver Creating service DockerSwarmGoDemo_edge-server Creating service DockerSwarmGoDemo_zipkin Creating service DockerSwarmGoDemo_accountservice Creating service DockerSwarmGoDemo_vipservice Creating service DockerSwarmGoDemo_imageservice Creating service DockerSwarmGoDemo_dvizz
