2. Using nvm install node 17.4.0
3. Install Docker
4. Install Docker Compose 2.0
5. Create Docker registry

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

6. Build the application's container

$ docker compose build

7. Publish application container image

$ docker compose push

8. Initialize Docker Swarm

$ docker swarm init --advertise-addr <your-ip-goes-here>
