Look-around Docker for AWS

docker node ls

# launch container in host's process, network, and fs namespaces
docker run --rm -it --privileged --net=host --pid=host -v /:/host alpine sh
hostname
ls /host/etc/*release
cat /host/etc/os-release
ps -ef | grep docker
export DOCKER_HOST='0.0.0.0:2375'
/host/usr/bin/docker ps

Application Demos

# ---------------- example-voting-app ----------------

# deploy on dev machine
cd example-voting-app
unset DOCKER_HOST
docker-compose up --force-recreate
docker-compose bundle

# deploy to SwarmV2
export DOCKER_HOST=ec2-54-183-78-22.us-west-1.compute.amazonaws.com:2375
docker stack deploy examplevotingapp
docker stack ps examplevotingapp
less examplevotingapp.dab

# check-out on SwarmV2
docker service ls
docker service inspect examplevotingapp_vote | jq '.[0] | { EndpointPorts: .Endpoint.Ports }'
docker service inspect examplevotingapp_result | jq '.[0] | { EndpointPorts: .Endpoint.Ports }'

# optional, but must match ELB
docker service update examplevotingapp_vote --publish-add "5000:80"
docker service update examplevotingapp_result --publish-add "5001:80"

# Add to Docker-ELB
