Docker images for Vapor

Docker images for multi staged builds of Vapor apps. Run your Swift app in a 65 MB small Image.

Useage in Dockerfile

Build the Images

docker build -f Dockerfile-builder -t vapor-builder .
docker build -f Dockerfile-runner -t vapor-runner .

You can build your app image using the builder and runner.

FROM vapor-builder:latest as builder
WORKDIR /app/
COPY . .

RUN mkdir -p /build/lib && cp -R /usr/lib/swift/linux/*.so /build/lib
RUN swift build -c release && mv `swift build -c release --show-bin-path` /build/bin


FROM vapor-runner

WORKDIR /app/
COPY --from=builder /app/docker-entrypoint.sh /app/docker-entrypoint.sh
COPY --from=builder /build/bin .
COPY --from=builder /build/lib/* /usr/lib/
COPY --from=builder /app/Config ./Config
# COPY --from=builder /app/Resources ./Resources  # only if you use views
