authentik 2026.8.5 build recipe
The recipe ReadyStack built readystack/authentik:2026.8.5-CE-ubuntu24.04-r3 from: the upstream source it starts from, every pinned input, and the files that run the build with the network off. Public here: the source and commit, the pinned inputs, all 24 recipe files with their sizes and SHA-256, 9 of them public in full or in part, and the opening lines of the Dockerfile and build script.

Fetched once, with the network on, by the vendor step (Dockerfile.vendor) when the kit was made; the offline build uses the kit's vendored copies:
- git https://github.com/goauthentik/authentik version/${AUTHENTIK_VERSION}
- https://www.python.org/ftp/python/3.14.8/Python-3.14.8.tar.xz

# Rebuilds this product's image from THIS ARCHIVE ALONE, with no network access
