The code for this book was written several years ago. I’m struggling to get things working with current tools. Even running the code included with the book doesn’t work anymore. For instance, taking the first-pass code, running the database using the docker-compose.yaml file, I get timeouts trying to connect to the database. So, the question is, is there a route for getting support to be able to use the content of the book using current tools, or is this book now essentially pointless because the examples are no longer valid?
