ci: publish the Zig FFI library image to GHCR#49
Merged
Conversation
Add a publish-image workflow + Containerfile so checky-monkey publishes its own
GHCR image, re-linking the ghcr.io/hyperpolymath/checky-monkey package back to
this repo (it was previously mis-attributed to odds-and-sods-package-manager,
which built a Rust/axum service that does not exist here).
checky-monkey is currently a Zig C-ABI library (libchecky_monkey.{so,a}) with
Idris2 ABI bindings — not a running service — so the image is a distribution
artifact carrying the compiled library for downstream FFI consumers.
Also fixes a pre-existing compile error so the library builds:
- ffi/zig/src/main.zig: `Handle` was declared as `opaque { ...fields... }`,
which Zig rejects (opaque types cannot carry fields). Declared it as a struct;
it is still exposed to C only as an opaque `*Handle` pointer.
- The Containerfile builds the lib directly with `zig build-lib ... -lc` (libc
is needed for std.heap.c_allocator), bypassing the in-tree build.zig, which is
a not-yet-instantiated scaffold template ({{project}} placeholders + a missing
include/ header).
Verified locally with Zig 0.13.0: both the shared and static libraries build.
Actions are SHA-pinned, permissions least-privilege, provenance attested.

What
Adds a
Containerfile+.github/workflows/publish-image.ymlso checky-monkey publishes its own image toghcr.io/hyperpolymath/checky-monkey, and fixes a pre-existing Zig compile error so the library actually builds.Why
Part of the cross-repo GHCR attribution cleanup. The
checky-monkeypackage was mis-attributed toodds-and-sods-package-manager, whose vendored Containerfile built a Rust/axum service that does not exist in this repo. Publishing from here re-links the package to its real source.What the image is
checky-monkey on disk is a Zig C-ABI library (
libchecky_monkey.{so,a}) with Idris2 ABI bindings — not a running service (the Haskell/Servant platform in the README/TOPOLOGY is aspirational and not yet on disk). So the image is a distribution artifact carrying the compiled library (and its source) for downstream FFI consumers toCOPY --from. NoEXPOSE/serviceHEALTHCHECK.Source fix (so it compiles)
ffi/zig/src/main.zig:Handlewas declared asopaque { allocator, initialized }, which Zig rejects — opaque types cannot carry fields. Changed to astruct(still exposed to C only as an opaque*Handlepointer, so the C-ABI is unchanged).zig build-lib src/main.zig ... -lc(libc is required bystd.heap.c_allocator), bypassing the in-treebuild.zig, which is a not-yet-instantiated scaffold template ({{project}}placeholders + a referenced-but-missinginclude/header).Verification
Built locally with Zig 0.13.0: after the
opaque→structfix and-lc, bothlibchecky_monkey.soandlibchecky_monkey.abuild cleanly.🤖 Generated with Claude Code
