Trying out pull request changes in an OpenShift cluster

For the remainder of this guide, we'll assume the branch you want to try out is named feature/some-new-functionality, and ODS Pipeline is already installed in a namespace called foo-cd. Adjust as necessary throughout.

Create a BuildConfig resource for every image you need to build, that is start, finish and pipeline-manager.

Example configuration for start:

kind: BuildConfig
apiVersion: build.openshift.io/v1
metadata:
  name: ods-start-preview
  namespace: foo-cd
spec:
  nodeSelector: null
  output:
    to:
      kind: ImageStreamTag
      name: 'start:latest'
  resources: {}
  successfulBuildsHistoryLimit: 5
  failedBuildsHistoryLimit: 5
  strategy:
    type: Docker
    dockerStrategy:
      dockerfilePath: build/images/Dockerfile.start
  postCommit: {}
  source:
    type: Git
    git:
      uri: 'https://github.com/opendevstack/ods-pipeline'
      ref: feature/some-new-functionality
  runPolicy: Serial

Also, for each build config, create an ImageStream with corresponding name (for the example above, start).

After all images have been created, run the install script from the deploy directory like this:

./install.sh -n=foo-cd \
  --local-chart \
  --set imageRepository=image-registry.openshift-image-registry.svc:5000/foo-cd,imageTag=latest

Note: if ODS Pipeline has not been installed prior, you'll need to create a values.yaml file before running this, as explained in the normal installation guide.
