9.3. Builder Cartridge Life Cycle

If an application includes a builder cartridge, OpenShift Enterprise does not perform build tasks. Instead, the builder cartridge runs the build process.
During the Git pre-receive hook, OpenShift Enterprise runs the builder cartridge's control pre-receive command.
During the Git post-receive hook, OpenShift Enterprise runs the builder cartridge's control post-receive command.

Note

Build processes use the application developer's gear resources to run. When implementing a builder cartridge, do not copy source code or build artifacts more than necessary.
