# infra > OSS-Fuzz project infrastructure Core infrastructure: * [`base-images`](base-images/) - docker images for building fuzzers & corresponding jenkins pipeline. Continuous Integration infrastracture: * [`libfuzzer-pipeline.groovy`](libfuzzer-pipeline.groovy/) - jenkins pipeline that runs for each oss-fuzz project. * [`docker-cleanup`](docker-cleanup/) - jenkins pipeline to clean stale docker images & processes. * [`push-images`](push-images/) - jenkins pipeline to push built base images. * [`jenkins-cluster`](jenkins-cluster/) - kubernetes cluster definition for our jenkins-based build (not operational yet). ## helper.py > script to automate common docker operations | Command | Description | |---------|------------- | `generate` | | `build_image` | | `build_fuzzers` | | `run_fuzzer` | | `coverage` | | `shell` |
