wtf is qnap-32k-containers?

This project fixes a specific compatibility problem on certain QNAP network storage devices, such as the TS-431P3 and TS-231P3, that use older 32 bit ARM processors. On these devices, many normal Docker container apps crash the instant you try to run them, showing an exit code with no error message in the logs at all. The README explains that this happens for two reasons. First, these NAS devices use 32 bit ARM chips, so they can only run software built for that specific processor type, not the 64 bit or Intel style images most software ships today. Second, and more unusual, QNAP built the operating system on these models to use a much larger memory page size than standard Linux uses. Most modern container images, even ones built for the right processor, are built assuming the standard smaller page size, so they fail to load correctly and crash right away. The project includes a table showing which base system versions still work and which ones crash, based on testing on a real device. Rather than rebuilding each app from its source code, the project's approach is to keep the official binaries and files from each upstream project untouched wherever possible, and only rebuild the surrounding operating system layer using an older, compatible base system. This keeps updates simple: pulling in a newer version of the underlying app usually just means rerunning the build. The repository currently offers five ready made container images: a working version of Pi-hole, a network wide ad blocker, Syncthing, a file synchronization tool, Ladder, a tool for reading articles behind soft paywalls, Stirling PDF, a web based PDF editing tool, and Vaultwarden, a self hosted password manager compatible with Bitwarden. Each one includes example commands or a configuration file to run it, along with specific notes about quirks, such as which exact version to use or what settings are required for it to work properly. To use any of these images, you pull them from GitHub's container registry and run them the same way you would any other Docker container, using either a plain docker run command or a Container Station compose file on the NAS itself.
