Describe the bug

The documentation for /Cookbooks/dockerize-adonis/ is incomplete by omitting what to do about the APP_KEY value. Following the instructions verbatim, and copy/pasting the config files here verbatim will result in the following output in the container's log.

The APP_KEY value is never mentioned in this guide.

It does seem like generating a new one and setting it would be the straightforward approach. If you have ideas on how we can articulate this better or any enhancements in mind, I'd warmly welcome a Pull Request from you.
