 ## Kaniko
 
-The `kaniko` ClusterBuildStrategy is composed by Kaniko's `executor` [kaniko], with the objective of building a container-image, out of a `Dockerfile` and context directory. The `kaniko-trivy` ClusterBuildStrategy adds [trivy](https://github.com/aquasecurity/trivy) scanning and refuses to push images with critical vulnerabilities.

-#### Scanning with Trivy
-
-You can also incorporate scanning into the ClusterBuildStrategy. The `kaniko-trivy` ClusterBuildStrategy builds the image with `kaniko`, then scans with [trivy](https://github.com/aquasecurity/trivy). The BuildRun will then exit with an error if there is a critical vulnerability, instead of pushing the vulnerable image into the container registry.

-To install the cluster scope strategy, use:
-
-```sh
-kubectl apply -f samples/v1beta1/buildstrategy/kaniko/buildstrategy_kaniko-trivy_cr.yaml
-```
-
-*Note: doing image scanning is not a substitute for trusting the Dockerfile you are building. The build process itself is also susceptible if the Dockerfile has a vulnerability. Frameworks/strategies such as build-packs or source-to-image (which avoid directly building a Dockerfile) should be considered if you need guardrails around the code you want to build.*
