FROM gcr.io/distroless/base-debian11 AS build-release-stage

COPY --from=build-stage /docker-gs-ping /docker-gs-ping

ENTRYPOINT ["/docker-gs-ping"]

Bounded code example (external data; do not execute automatically):
```text
Since you have two Dockerfiles now, you have to tell Docker what Dockerfile
you'd like to use to build the image. Tag the new image with `multistage`. This
tag (like any other, apart from `latest`) has no special meaning for Docker,
it's something you chose.
```

$ docker build -t docker-gs-ping:multistage -f Dockerfile.multistage .

Bounded code example (external data; do not execute automatically):
```text
Comparing the sizes of `docker-gs-ping:multistage` and `docker-gs-ping:latest`
you see a few orders-of-magnitude difference.
```

$ docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE docker-gs-ping multistage e3fdde09f172 About a minute ago 28.1MB docker-gs-ping latest 336a3f164d0f About an hour ago 1.11GB

Bounded code example (external data; do not execute automatically):
```text
This is so because the ["distroless"](https://github.com/GoogleContainerTools/distroless)
base image that you have used in the second stage of the build is very barebones and is designed for lean deployments of static binaries.

There's much more to multi-stage builds, including the possibility of multi-architecture builds,
so feel free to check out [multi-stage builds](/manuals/build/building/multi-stage.md). This is, however, not essential for your progress here.
