nodejs-mongo-client

Basic dockerized nodejs application using mongodb. This project makes usage of:

• express
• mongoose
• async/await

Build docker image

docker build --rm -t nodejs-mongo-client:0.0.1 .

Run as a container

Before creating the service, set the environment variables:

• NETWORK_NAME: this your swarm overlay network
  
  docker run -d
  --rm
  --network ${NETWORK_NAME}
  --name nodejs-mongo-client
  --env MONGODB_SERVER_NAME=(swarm service name or mongo server IP/Name)
  --env LISTEN_PORT=3000
  --publish 3331:3000
  nodejs-mongo-client:0.0.1

If your mongodb instance run as a docker swarm service, and in an overlay network, you have to attach the container to the same network. This allows the application connecting to the mongodb instance using the service name. In this case, launch the container as follows: docker run --rm --network NETWORK-NAME --name nodejs-mongo-client nodejs-mongo-client:0.0.1

Run as a service

Before creating the service, set the environment variables:

• NETWORK_NAME: this your swarm overlay network
• SERVICE_NAME: service name that will be pusblished by swarm
  
  docker service create
  --mode global
  --network ${NETWORK_NAME}
  --name nodejs-mongo-client
  --env MONGODB_SERVER_NAME=(swarm mongo service name)
  --env LISTEN_PORT=3000
  --publish target=3000,published=3331
  nodejs-mongo-client:0.0.1 To check your service is created and running, run docker service ls

Check your service

• list the existing users : curl http://localhost:3331/users
• get specific user : curl http://localhost:3331/user/
• create a new user: curl -X POST http://localhost:3331/user -d '{"email":"[email protected]","password":"user1"}' -H "Content-Type: application/json"
