This is the container that runs on https://slack.bazel.build/.

To build it:

docker build \
    -f bazel-slack-inviter-slackin/Dockerfile \
    --target bazel-slack-inviter-slackin \
    -t "gcr.io/bazel-public/bazel-slack-inviter-slackin" \
    docker

To push it to GCR:

docker push "gcr.io/bazel-public/bazel-slack-inviter-slackin"

In case the new container isn't picked up or slack.bazel.build starts to throw errors, go to Cloud Run and deploy a new version. The default settings should work fine.
