Metadata Bundle Image

The bundle image will house your metadata including the CSV.yaml, and the CRD.yaml.

When we ran the make bundle command earlier, part of what was generated was the metadata bundle image.

[nhartman@fedora wordpress]$ ls
bin                charts      Dockerfile   Makefile   requirements.lock  values.schema.json
bundle             Chart.yaml  helm-charts  PROJECT    requirements.yaml  values.yaml
bundle.Dockerfile  config      licenses     README.md  templates          watches.yaml

Here you see the bundle.Dockerfile in the root directory of your operator project. This is your Dockerfile for your metadata bundle image.

There are up to 3 labels you will need to add to the Dockerfile:

• LABEL com.redhat.openshift.versions

  • This lists OpenShift versions, starting with 4.5, that your operator will support. See the section Managing OpenShift Versions for syntax and rules.

• LABEL com.redhat.delivery.operator.bundle=true

  • This just needs to be there

• LABEL com.redhat.deliver.backport=true

  • This is used to indicate support for OpenShift versions before 4.6. If you don't specify this flag, your operator won't be listed in 4.5 or earlier.

#Add these labels

COPY bundle/metadata /metadata/
COPY bundle/tests/scorecard /tests/scorecard/

Now lets build the bundle image from the bundle.Dockerfile. You can use an existing public container registry of your choice, though we recommend using quay.io. When you create a new repository make sure its publicly available.

The next step is to build the bundle-dockerfile locally and push it to quay.io for testing which we will cover in the Deploying onto OpenShift section

podman build -t quay.io/<namespace>/wordpress-operator:v0.0.1 -f bundle.Dockerfile

podman push quay.io/<namespace>/wordpress-operator:v0.0.1
