Generic Builder
Buildpacks has a default generic builder that creates container
images designed to run on Google Cloud services, including but not limited to:
Google Kubernetes Engine, GKE Enterprise, Cloud Run, App Engine, and
Cloud Run functions.
The buildpacks generic builder:
Automatically detects the language of your source code.
Determines if that source code is an application (service) or function.
Builds your source code into a deployable container image.
The generic builder itself is a container image that's publicly hosted on
Container Registry.
To always use the most recent version and operating system, you can specify the
latest tag. The latest tag defaults to the google-22 version of the
generic builder and is used when you run the gcloud run deploy command.
If you need to pin to a version, see the instructions about how to
Use a specific builder.
Buildpacks also publish the builders that are used to
containerize applications for the App Engine
second-generation runtimes.
The App Engine builders include additional buildpacks and
App Engine-specific configurations. For example, they are optimized for
execution speed and automatic updates. Builders are by runtime language and
operating system:
