make: *** [run-api-node] Error 1

On node version 19.4.0, It gives me this error.

I then switched the node version to 20.0.0, and it was able to run successfully.

As I see you are not using ports directive in docker-swarm.yml:

@sidpalas can you please share a knolage on how to connect the database to manage data from your comuter?

I tried to use the following instructions but without success:

• https://code.visualstudio.com/docs/containers/ssh
• https://guillim.github.io/ssh,/docker/2020/03/11/ssh-port-forwarding-with-docker.html

What I have tried locally:

cd 12-deploying-containers/docker-swarm
docker context create example --docker "host=ssh://root@example-app-server-ip:22"
docker context use example
docker stack deploy -c docker-swarm.yml example-app # deployed your example to VPS
docker ps # to get container id: 148cac4c4793
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 148cac4c4793 # to get container ip: 10.0.11.3
ssh -L 5432:10.0.11.3:5432 root@example-app-server-ip # connected to docker swarm server
psql --version # psql (PostgreSQL) 15.3 (Homebrew)
psql -h 127.0.0.1 -p 5432 -U postgres postgres

psql: error: connection to server at "127.0.0.1", port 5432 failed: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

P.S.: Thank you for the tutorial, it is really helpful!
