Mastodon, the federated social network server (web and sidekiq). Built from the release tag on a hardened Wolfi ruby-4.0 runtime with every gem compiled from source against Wolfi's libvips, libpq, ICU and libxml2, and the web assets compiled at build time, so no Node ships at runtime. Nonroot, read-only rootfs; PostgreSQL and Redis are external. The streaming server is a separate image.
