peakoperator

peakoperator is an Ansible Operator for deploying and managing Peak services on a Kubernetes cluster.

Building the operator image

The operator image is built using the operator-sdk. You will require Docker installed on your host machine.

operator-sdk build  quay.io/peak/peak-operator:v0.1.7
docker push quay.io/peak/peak-operator:v0.1.7

Deploying the operator and CRD on OpenShift

As the system:admin user, create the CRD and a cluster-role allowing users to query the peak-services API

oc create -f deploy/cluster/clusterrole.yaml
oc create -f deploy/crds/services_v1alpha2_peakservice_crd.yaml

Login again as a regular user, create a new project, and create the resources required for the operator:

oc login -u user1 master.openshift.example.com
oc new-project peak
oc apply -f deploy

Observe the operator pod deploying, and verify that it has started successfully

$ oc get pods
NAME                             READY     STATUS    RESTARTS   AGE
peak-operator-66786764db-q5j4r   1/1       Running   0          8s

$ oc logs -f peak-operator-66786764db-q5j4r

Create the example PeakService resource

oc create -f deploy/crds/services_v1alpha2_peakservice_cr.yaml

Verify that the Peak pods begin to deploy. You can follow the operator logs to verify there are no errors during deployment:
