Request: Publish Docker image to container registry

[DanielPBak]

Summary

Would it be possible to publish pre-built Docker images to a container registry?

Use Case

We're deploying grpcmcp in Kubernetes as an MCP server to expose gRPC services. Currently, there's no official container image, so users have to build their own.

Registry Options

Any of these would be great:

• GitHub Container Registry (GHCR) - ghcr.io/adiom-data/grpcmcp - free, integrates with GitHub Actions
• Docker Hub - adiom/grpcmcp - widely used
• Chainguard - cgr.dev/chainguard/grpcmcp - security-focused, minimal images
• Alpine - if accepted into Alpine packages

Suggested Dockerfile

A simple multi-stage build:

FROM golang:1.22-alpine AS builder
RUN go install github.com/adiom-data/grpcmcp@latest

FROM alpine:3.19
RUN apk add --no-cache ca-certificates
COPY --from=builder /go/bin/grpcmcp /usr/local/bin/
ENTRYPOINT ["grpcmcp"]

Or even better, a distroless/scratch-based image for minimal attack surface.

Benefits

• Easier Kubernetes deployments
• No need for users to maintain custom builds
• Version pinning via image tags
• Security scanning by registry providers

Thanks for the great tool!
