fix(docker): use glibc base image so local embeddings load#97
Merged
Conversation
@huggingface/transformers eagerly requires the native onnxruntime-node at import, whose prebuilt binary is glibc-only and cannot dlopen on Alpine/musl (fails with ERR_DLOPEN_FAILED, and gcompat does not provide the glibc fortify symbols it needs). With EMBEDDING_PROVIDER=local this crashed the app on boot. Switch both Dockerfile stages to node:22-slim (glibc), where onnxruntime-node loads natively, which is also faster than the WASM fallback. The local embedding adapter now uses the default native backend instead of forcing WASM. The compose healthcheck moves from wget (absent on slim) to a node fetch one-liner. Verified on the target host: app boots clean and an in-container embed returns a 384-dim vector.
