Building And Deploying

Setup

Create Custom Resource Definition (CRD)

oc apply -f deploy/crds/managed.openshift.io_customdomains_crd.yaml

Run locally outside of cluster

operator-sdk run --local --namespace ''

Build and Deploy To Cluster

Choose public container registry e.g. 'quay.io/acme'. Build and push the image, then update the operator deployment manifest.

Example:

# deploy manifests
oc apply -f deploy/crds/managed.openshift.io_customdomains_crd.yaml
oc apply -f deploy/
# build
make docker-build docker-push
# update image with image in build output
oc set image -n openshift-custom-domains-operator deployment/custom-domains-operator custom-domains-operator=quay.io/dustman9000/custom-domains-operator:v0.1.29-a48b301e
