Part12 Containers Applications
Script-answers contains the code executed (recorded by the script command) as I was following the exercises given, such as installing node and authenticating with mongoDB inside running containers. The other folders contain starter projects that were modified as per instructions.
Bloglist Docker
Yet another version of the bloglist app, this time configured to run both the frontend and backend using docker-compose. Includes a dev environment that allows for hot-reloading and automatic nodemon restarts, and a production environment.
Notes
Reverse-proxying was the most difficult part of this whole part, for me. I spend most of these 35 hours just trying to get Nginx to work properly, and was never really able to. I ended up forgoing it in favor of just manually proxying the requests, not very scalable but I solved the problem!
Total hours: 35
