I watched this entire series and wanted to say thank you so much. This was exactly what I needed to get started and this series deserves way more views than it does now. There's nothing like it from what I came across.

Thanks for the content. You helped me a lot. I only use dockerize instead of pg_isready.

I just found this, and I'm to the step just before this video. I'm on Windows, but I'm trying to create a learning resource for people, so I don't want to do a solution that won't work cross-platform. I'm curious about why your solution uses the shell vs. just using the container you created that runs the app?

This tutorial really helped me a lot, thanks!

My only issue is that whenever I run the test script, it throws the error "getaddrinfo ENOTFOUND postgres" (postgres is the service name of the database in docker compose). From what I gather, the express app can't find the postgres container when running the test. But when I run both the express app and the postgreSQL in a container, I can access the database through postman.

I'm using Docker Desktop with Docker 24.0.6. I'm also using node-postgres to connect my express app to postgreSQL and I'm sure that the hostname I'm using is the same with the service name of the database in docker-compose.yml. Is this a DNS or a networking problem? Do you have any idea on how I can fix this?

Any alternative for windows? chmod isn't a command on windows. Currently looking for potential solution but otherwise awesome video!

Hi, this is very good tutorial about nodejs and postgresql with docker-compose. Not so much good material out there. I have a question if i want to use CI/CD with AWS this code is it possible?
