Buildah ClusterBuildStrategy

The buildah ClusterBuildStrategy uses buildah to build and push a container image, out of a Dockerfile or Containerfile. The Dockerfile should be specified using the dockerfile parameter in the Build resource.

Install the Strategy

$ oc apply -f https://raw.githubusercontent.com/redhat-developer/openshift-builds-catalog/main/clusterBuildStrategy/buildah/buildah.yaml

Usage

This example uses the buildah strategy to build an image using a Dockerfile, and pushes the image to OpenShift's internal registry (output.image). The following example assumes the OpenShift internal registry is enabled and the BuildRun executes in the buildah-sample namespace:

kind: Build
metadata:
  name: buildah-golang-build
spec:
  source:
    git: 
      url: https://github.com/shipwright-io/sample-go
    contextDir: docker-build
  strategy:
    name: buildah
    kind: ClusterBuildStrategy
  paramValues:
  - name: dockerfile
    value: Dockerfile
  output:
    image: image-registry.openshift-image-registry.svc:5000/buildah-example/sample-go-app
