# Internal

This directory contains internal code for cloud.google.com/go packages.

## .repo-metadata-full.json

`.repo-metadata-full.json` contains metadata about the packages in this repo. It
is generated by `internal/gapicgen/generator`. It's processed by external tools
to build lists of all of the packages.

Don't make breaking changes to the format without consulting with the external
tools.

One day, we may want to create individual `.repo-metadata.json` files next to
each package, which is the pattern followed by some other languages. External
tools would then talk to pkg.go.dev or some other service to get the overall
list of packages and use the `.repo-metadata.json` files to get the additional
metadata required. For now, `.repo-metadata-full.json` includes everything.

## cloudbuild.yaml

The `cloudbuild.yaml` Cloud Build configuration currently supports:

* Building a docker container from the `internal/postprocessor/Dockerfile`.

The build can be run locally in the `google-cloud-go` root directory:

```bash
gcloud builds submit --project=cloud-devrel-kokoro-resources --config=internal/cloudbuild.yaml
```

See the [postprocessor/README](postprocessor/README.md) for instructions
regarding updating the post-processor docker container.

### Updating OwlBot SHA

You may want to manually update the which version of the post-processor will be
used -- to do this you need to update the SHA in the OwlBot lock file.

See the [postprocessor/README](postprocessor/README.md) for detailed
instructions.

*Note*: OwlBot will eventually open a pull request to update this value if it
discovers a new version of the container.
