thanks for this

Thanks! I used this to make:

FROM golang:1.23.5-alpine3.21 as golang
ENV GO111MODULE=on
RUN go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest \
  && go install google.golang.org/protobuf/cmd/protoc-gen-go@latest \
    && go install \
           connectrpc.com/connect/cmd/protoc-gen-connect-go@latest

FROM bufbuild/buf:1.50.0 as buf

FROM node:22-alpine3.20 as node
COPY --from=golang /go/bin/protoc-gen-go /go/bin/protoc-gen-go
COPY --from=golang /go/bin/protoc-gen-connect-go /go/bin/protoc-gen-connect-go
COPY --from=buf /usr/local/bin/buf /usr/local/bin/buf
RUN npm install --g @bufbuild/protoc-gen-es
ENV PATH="/go/bin:/usr/local/lib/node_modules/@bufbuild/protoc-gen-es/node_modules/.bin:${PATH}"
COPY ./sh/generate_inside_docker.sh /usr/bin/generate_inside_docker.sh
ENTRYPOINT ["/usr/bin/generate_inside_docker.sh"]

With generate_inside_docker.sh being:

#!/bin/sh

buf build
buf generate
echo "Successfully generated protobuf files."
