How to Properly Cache Content Hosted on Backblaze B2

Summary

Because I use Cloudflare to manage my domains and Backblaze for backups, it only made sense to take advantage of their Bandwidth Alliance for creating my own CDN. This has been incredibly helpful for image hosting for this knowledge base, however, I recently noticed that caching wasn't working as it should.

The Problem

The overall problem started when I was adding a parking page for a domain I recently purchased. The background image was hosted on B2 and the image was supposed to be cached by Cloudflare. However, each time the page loaded, it would pull the image from the origin instead of the cache. I checked this on my knowledge base and found it was doing the same thing.

Internet Archive (archive.org) multi-file item downloading

Finding an item to download

1. Find an item that you'd like to download (for example: https://archive.org/details/SuperNintendoUSACollectionByGhostware)
2. Grab its "identifier" (you can see it in the HTML of the page, but otherwise just use the last part of the URL for a "details" page)

Downloading the files

At this point, you could just download the files by clicking on them on the HTML page, but that's slow and concurrent-download-limited... Sooo...

Connect services with docker-compose at multirepo project

Sometimes you have a project with different services (or microservices) and each one of them has its own repository. At those cases, tests the whole project (and its interactions) can be challenging.

With Docker and Docker Compose you can run easily each service from its repo, but for making them to see each other you (usually) need to manually create a network with Docker, assume so facts (as directories names) or do some crazy network configurations.

TL;DR

You have the final configuration here.
