mongodb operator deployment in openshift "Failed to apply default image tag "/:4.2.6" invalid reference format"

Im referring to mongodb community operator from https://github.com/mongodb/mongodb-kubernetes-operator and trying to deploy it in openshift or okd

git clone https://github.com/mongodb/mongodb-kubernetes-operator.git
cd mongodb-kubernetes-operator 
kubectl create namespace mongodb
kubectl create -f deploy/operator/role.yaml --namespace mongodb
kubectl create -f deploy/operator/role_binding.yaml --namespace mongodb
kubectl create -f deploy/operator/service_account.yaml --namespace mongodb
kubectl create -f deploy/crds/mongodb.com_mongodb_crd.yaml --namespace mongodb

oc apply -f deploy/openshift/operator_openshift.yaml -n mongodb
oc apply -f deploy/crds/mongodb.com_v1_mongodb_openshift_cr.yaml -n mongodb

Operator pod is successfully running but mongodb replica set pods does not come up. Error is as follows

[kubenode@master mongodb-kubernetes-operator]$ oc get pods
NAME                                           READY     STATUS             RESTARTS   AGE

 Failed to apply default image tag "/:4.2.6": couldn't parse image reference "/:4.2.6": invalid reference format

enter image description here Here as the error indicates it is pulling the wrong image and i tried to update the image using oc edit statefulset.apps/example-openshift-mongodb. Once I update the image name correctly and save, i dont see the changes saved. Please let me know what could be done to update the image to right one

Solution

  • I realized that since mongo statefulset are created using operator and crd https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/ the changes done directly to statefulsets are not getting saved. Hence editing the the crd file that is https://github.com/mongodb/mongodb-kubernetes-operator/blob/master/deploy/crds/mongodb.com_v1_mongodb_openshift_cr.yaml has helped me to solve the issue. Add a new line with image: mongo:4.2.6 after line no 33 in the mongodb.com_v1_mongodb_openshift_cr.yaml and then deploy
