Compiling Containers
summary
Claim: BuildKit is the actual compiler behind docker build not just a builder UI and it exposes an llb IR so frontends and backends interoperate. Proof: using buildctl plus a moby/buildkit daemon, a Go program emits protobuf llb, pushable to Docker Hub, and the resulting image runs as expected. Demonstrations include a programmatic builder and an INTERCAL‑style frontend fetched via Docker syntax; BuildKit offers concurrent, distributed builds and aggressive caching used by tens of projects.
