Steps to Deploy Node-Express-Boilerplate

Follow these steps to deploy node-express-boilerplate:

1. Install docker

2. Prepare 3 hosts

   

3. Open protocols and ports between the hosts(Ubuntu). The following ports must be available. On some systems, these ports are open by default.

• Port 2377 TCP for communication with and between manager nodes

• Port 7946 TCP/UDP for overlay network node discovery

• Port 4789 UDP (configurable) for overlay network traffic

  sudo iptables -A INPUT -p tcp --dport 2377 -j ACCEPT ; \\
  sudo iptables -A INPUT -p tcp --dport 7946 -j ACCEPT ; \\
  sudo iptables -A INPUT -p udp --dport 7946 -j ACCEPT ; \\
  sudo iptables -A INPUT -p udp --dport 4789 -j ACCEPT
  

  Note: Need all manager1, worker1, worker2 apply this one

4. Create a swarm

docker swarm init

1. Add nodes to the swarm Connect to these other hosts to add that node to the manager swarm We call these other hosts may be: “worker1”, “worker2” By TOKEN when create swarm

   docker swarm join --token <TOKEN> <MANGER_IP>:2377
   

2. Clone the repository:

   git clone <https://github.com/AnhtuanUit/node-express-boilerplate>
   
   

3. Go to the source code

   cd node-express-boilerplate
   
   

4. Set environment variables:

   cp .env.example .env
   
   

   Update .env with your own environment variables. Note: make sure you prepare the .env file before you run the docker scripts because the .env will be copied to Docker Image the first time run the docker scripts.

5. Install docker-compose to test the docker-compose.yml file first

   All in one command 😛

   sudo curl -L "<https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$>(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
   sudo chmod +x /usr/local/bin/docker-compose
   docker-compose --version
   

6. Test docker-compose.yml file (for swarm mode deploy stack services)

   docker-compose -f docker-compose.yml -f docker-compose.dev.yml -f docker-compose.swarm.yml up
   
   

7. Check that the app is running with docker-compose ps:

   docker-compose ps
   

   You can test the app with curl:

   curl <http://localhost:3000>
   curl <http://localhost:27017>
   

8. Bring the app down:

   docker-compose -f docker-compose.yml -f docker-compose.dev.yml -f docker-compose.swarm.yml down -d
   

9. Set up a Docker registry

   docker service create --name registry --publish published=5000,target=5000 registry:2
