Behaviour
Steps to reproduce this issue
- Use following Dockerfile:
FROM golang:1.19-buster as build-env
ARG SECRETS_PATH="build/package/secrets"
COPY ${SECRETS_PATH} /secrets
WORKDIR /build
## Snip... set up private go repo
COPY go.* ./
RUN go mod download
COPY . .
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o /tmp/insights cmd/insights/main.go
FROM scratch
COPY --from=build-env /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/ca-certificates.crt
COPY --from=build-env /tmp/insights ./insights
EXPOSE 8080
ENTRYPOINT ["/insights"]
- Build in GHA once to write the cache
- Build again to read the cache
Expected behaviour
All operations should be cached, since nothing in the build has changed since the previous run
Actual behaviour
The final image's operations are cached, but not the pre-stage where most of the work is
