Example Code

I wanted to test the template "as is" but failed to get working in my MacOS laptop. Below are the steps I have taken:
1. Git cloned the project to a local folder in my MacOS laptop.
2. Opened the folder using VS Code. Chose "docker-compose.yml" and ran "Compose Up"
3. Confirmed all 4 containers were up and running by running "docker ps"
4. Checked docker-compose logs and spotted no errors
5. Opened "http://localhost" in Chrome. Received an error: This site can’t be reached. Localhost refused to connect."

What did I miss?

Description

Opened browser and typed "http://localhost/". Received an error: This site can’t be reached. Localhost refused to connect.

The problem is that when you run it with the context menu "compose up" command, it doesn't apply instructions from docker-compose.override.yml and you containers ports are not mapped to the ports on host machine.

To solve this, run stack with docker compose watch CLI command as it's described in docs and then access your services using their ports:

Frontend: http://localhost:5173/

Backend: http://localhost:8000/docs

Adminer: http://localhost:8080/

Traefik UI: http://localhost:8090/

MailCatcher: http://localhost:1080/
