George Fogle article about how to find a better, more productive development workflow with Docker. Docker and container-based development is really going to save you time in the future. As well as make working and debugging code a breeze.
A container is acting like an entirely separate computer, even though it’s on your computer. So using the name localhost inside of a container is not the same as using localhost in code that is running on your computer.
The article then explain how to use:
- Docker Compose
