# 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

To kick off a build locally run from the repo root:

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

### 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. Start by
running the following commands:

```bash
docker pull gcr.io/cloud-devrel-public-resources/owlbot-go:latest
docker inspect --format='{{index .RepoDigests 0}}' gcr.io/cloud-devrel-public-resources/owlbot-go:latest
```

This will give you a SHA. You can use this value to update the value in
`.github/.OwlBot.lock.yaml`.

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