Builders

For a subset of the clients above, we have developed remote builders, meaning that you can issue a command locally to use your remote credential to deploy a remote builder. We provide details for builders here.

• Google Compute: Build an image on Google Compute and upload to Google Storage.

Debugging

Troubleshooting is just as important as usage! Here are some quick guides to debugging common errors. If you have an error that isn’t represented, please reach out.

• Docker Pulling Errors: walk through pulling a container from gcr.io and inspecting the manifest responses.
• Google Cloud Errors interact with the Google Cloud Python API to reveal underlying reasons you can’t connect to a bucket or service.
