This repository provides OCI Images with traefik-forward-auth binary, and that's all.
Official Docker build for traefik-forward-auth were built in June 2021 (for the "latest" tag) and doesn't seem to be updated since. In addition, the 2-arm or 2.2.0-arm tags were tagged as linux/amd64 platforms and built on June 2020.
Some bugs were fixed in latest releases, but no official Docker images seems to have been built with these up-to-date releases.
This repository build images by downloading an official traefik-forward-auth build from GitHub releases. Thus, it only provides amd64 and arm versions.
If you need an OCI image with traefik-forward-auth built from source, or if you specifically needs an armv7 or arm64 version, check https://github.com/StefanSchoof/traefik-forward-auth/pkgs/container/traefik-forward-auth.
