Google Container Builder

The Google Container Builder is a managed service for building various application artifacts, primarily Docker images. When deploying a service to the flexible environment, Container Builder reads the app.yaml configuration file to determine how to build and package the source code into a Docker image. For custom runtimes, the Container Builder will create the image based on the provided Dockerfile.

When a deployment fails during the build phase, it is often useful to consult the build logs and related information provided by Container Builder. This can be done within the Cloud Console by navigating to Navigation menu | Container Registry | Build history. Viewing Container Builder builds requires the Container Builder Viewer or Container Viewer Editor role.
