Docker NodeJS Example with Docker EE 2.0

Prerequisites

• Docker EE 2.0
  • 17.06.3-ee-8 Docker Enterprise Engine
  • UCP 3.0.0
  • DTR 2.5.0

Setup UCP and DTR

Set up UCP and DTR per instructions found here: https://github.com/yongshin/vagrant-docker-ee-ubuntu.

Create DTR repo

engineering/docker-node-app

Build Docker Image

export DTR_IPADDR=dtr.local

git clone git@github.com:yongshin/docker-node-app.git
cd ~/docker-node-app
docker build -t $DTR_IPADDR/engineering/docker-node-app .
docker push $DTR_IPADDR/engineering/docker-node-app

Start Example Application

Swarm Mode

The following stack command brings up two Swarm mode services and deploys it with Interlock enabled. Make sure you have the Routing Mesh enabled inside of UCP before deploying.

# Source client bundle
docker stack deploy -c deploy/swarm/docker-compose.yml nodeapp

Kubernetes

# Source client bundle
kubectl apply -f deploy/k8s/nodeapp-demo.yaml

Stop all

Swarm Mode

This removes the entire stack including services

docker stack rm nodeapp

Kubernetes

This removes all of the K8S resources

kubectl delete -f deploy/k8s/nodeapp-demo.yaml

Run app locally for development purposes on Docker CE

This does not utilize Interlock and mainly leverages the internal Swarm Routing Mesh.

docker build -t yongshin/docker-node-app .
docker stack deploy -c deploy/swarm/docker-compose-local.yml nodeapp
