Description Jilju Joy 2023-06-30 10:17:19 UTC

+++ This bug was initially created as a clone of Bug #2212773 +++

Description of problem (please be detailed as possible and provide log
snippests):

While using both private link and non private link clusters, the ocs-provider-server service tries to come up on the  non private subnets of the VPC. This would mean that the endpoint will be exposed and from outside the subnets we can ping the endpoint.

The AWS ELB created is of type Classic which doesn't support private link clusters.
So we need to move to Network Load Balancer and use a internal facing load balancer so that it's only accessible from within the VPC.

We need to add annotations to the service as aws controller looks at the annotation to reconcile the service.

--- Additional comment from RHEL Program Management on 2023-06-06 10:12:39 UTC ---

This bug having no release flag set previously, is now set with release flag 'odf‑4.13.0' to '?', and so is being proposed to be fixed at the ODF 4.13.0 release. Note that the 3 Acks (pm_ack, devel_ack, qa_ack), if any previously set while release flag was missing, have now been reset since the Acks are to be set against a release flag.

--- Additional comment from Rewant on 2023-06-19 05:33:46 UTC ---

The ocs-operator should not be responsible for adding annotations based on the cloud provider, instead the loadbalancer should be created externally based on the cloud provider and the type of network (private/public), hence adding a new field in StorageCluster CR to toggle between the service type.

Comment 11 Itzhak 2023-08-08 10:28:53 UTC

I tested the BZ with the following steps:

1. Deploy an AWS 4.13 cluster without ODF.

2. Disable the default Red-hat operator:
$ oc patch operatorhub.config.openshift.io/cluster -p='{"spec":{"sources":[{"disabled":true,"name":"redhat-operators"}]}}' --type=merge

3. Get and apply ICPS from catalog image using the commands(in my local): 
$ oc image extract --filter-by-os linux/amd64 --registry-config ~/IBMProjects/ocs-ci/data/pull-secret quay.io/rhceph-dev/ocs-registry:latest-stable-4.13 --confirm --path /icsp.yaml:~/IBMProjects/ocs-ci/icsp
$ oc apply -f ~/IBMProjects/ocs-ci/icsp/icsp.yaml

5. Wait for the MachineConfigPool to be ready. 
$ oc get MachineConfigPool worker

6. Create the Namespace, CatalogSource, and Subscription using the Yaml file above: https://bugzilla.redhat.com/show_bug.cgi?id=2218863#c9.
$ oc apply -f ~/Downloads/deploy-with-olm.yaml

7. Wait until the ocs-operator pod is ready in the openshift-namespace.

8. Create the Storagecluster using the Yaml file above: https://bugzilla.redhat.com/show_bug.cgi?id=2218863#c10.
(If there is an issue with Noobaa CRDs, we may also need to apply this Yaml file https://raw.githubusercontent.com/red-hat-storage/mcg-osd-deployer/1eec1147b1ae70e938fa42dabc60453b8cd9449b/shim/crds/noobaa.noobaa.io.yaml). The field 'providerAPIServer' is empty in this Yaml file. 

9. Check the pods: 
$ oc get pods
NAME                                   READY   STATUS    RESTARTS        AGE
ocs-metrics-exporter-c67ff7957-v8p5b   1/1     Running   0               21m
ocs-operator-5f569b66cf-2dkcz          1/1     Running   5 (9m33s ago)   22m
rook-ceph-operator-7757dffc4c-ccdb5    1/1     Running   3 (77s ago)     7m42s


10. Check the service and see that the provider server is NodePort as this is the default value:
$ oc get service
NAME                  TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)           AGE
ocs-provider-server   NodePort   172.30.104.23   <none>        50051:31659/TCP   8m3s


11. Edit the ocs-storagecluster and change the value of "providerAPIServerServiceType" to LoadBalancer. Check the pods again:
$ oc get pods | grep ocs
ocs-metrics-exporter-c67ff7957-v8p5b            1/1     Running       0               25m
ocs-operator-5f569b66cf-2dkcz                   1/1     Running       5 (13m ago)     26m
ocs-provider-server-599c77c4db-2jm6t            1/1     Running       0               99s

12. Check the service type again:
$ oc get service
NAME                   TYPE           CLUSTER-IP      EXTERNAL-IP                                                              PORT(S)             AGE

13. Edit the ocs-storagecluster and change the value of "providerAPIServerServiceType" to NodePort. Check the service again:
$ oc get service
NAME                   TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)             AGE

ocs-provider-server    NodePort    172.30.104.23   <none>        50051:31659/TCP     14m

14. Edit the ocs-storagecluster and change the value of "providerAPIServerServiceType" to a dummy value "someValue". Check the ocs-operator logs and see the expected error: 
$ oc logs ocs-operator-5f569b66cf-2dkcz | tail -n 1
{"level":"error","ts":"2023-08-08T10:20:50Z","msg":"Reconciler error","controller":"storagecluster","controllerGroup":"ocs.openshift.io","controllerKind":"StorageCluster","StorageCluster":{"name":"ocs-storagecluster","namespace":"openshift-storage"},"namespace":"openshift-storage","name":"ocs-storagecluster","reconcileID":"c02bb1f2-ddf9-46a0-a986-bef98c60a07f","error":"providerAPIServer only supports service of type NodePort and LoadBalancer","stacktrace":"sigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).reconcileHandler\n\t/remote-source/app/vendor/sigs.k8s.io/controller-runtime/pkg/internal/controller/controller.go:329\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).processNextWorkItem\n\t/remote-source/app/vendor/sigs.k8s.io/controller-runtime/pkg/internal/controller/controller.go:274\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).Start.func2.2\n\t/remote-source/app/vendor/sigs.k8s.io/controller-runtime/pkg/internal/controller/controller.go:235"}

15. Edit the ocs-storagecluster and change the value of "providerAPIServerServiceType" to LoadBalancer. Check the service again:
$ oc get service

Comment 13 Itzhak 2023-08-16 09:30:19 UTC

We found an issue with the new ocs 4.11.10-1 image. In the case of NodePort Service, the ocs operator pod keeps requiring. 
We need to fix this from the ocs-operator side, backport the fix and test it again.

Comment 14 Itzhak 2023-08-21 16:11:14 UTC

I tested the BZ with the following steps:

1. Deploy an AWS 4.13 cluster without ODF.

2. Disable the default Red-hat operator:
$ oc patch operatorhub.config.openshift.io/cluster -p='{"spec":{"sources":[{"disabled":true,"name":"redhat-operators"}]}}' --type=merge

3. Get and apply ICPS from catalog image using the commands(in my local): 
$ oc image extract --filter-by-os linux/amd64 --registry-config ~/IBMProjects/ocs-ci/data/pull-secret quay.io/rhceph-dev/ocs-registry:latest-stable-4.13 --confirm --path /icsp.yaml:~/IBMProjects/ocs-ci/icsp
$ oc apply -f ~/IBMProjects/ocs-ci/icsp/icsp.yaml

5. Wait for the MachineConfigPool to be ready. 
$ oc get MachineConfigPool worker

6. Create the Namespace, CatalogSource, and Subscription using the Yaml file above: https://bugzilla.redhat.com/show_bug.cgi?id=2218863#c9. 
$ oc apply -f ~/Downloads/deploy-with-olm.yaml

7. Wait until the ocs-operator pod is ready in the openshift-namespace.
$ oc get pods
NAME                                    READY   STATUS    RESTARTS   AGE
ocs-metrics-exporter-5b4b5d9f4b-t66lw   1/1     Running   0          36s

rook-ceph-operator-5b8b94cb94-zsh5x     1/1     Running   0          36s

8. Create the Storagecluster using the Yaml file above: https://bugzilla.redhat.com/show_bug.cgi?id=2218863#c10. 
9. Apply the Yaml files //raw.githubusercontent.com/red-hat-storage/mcg-osd-deployer/1eec1147b1ae70e938fa42dabc60453b8cd9449b/shim/crds/noobaa.noobaa.io.yaml, and https://raw.githubusercontent.com/noobaa/noobaa-operator/5.12/deploy/obc/objectbucket.io_objectbucketclaims_crd.yaml(in order to get errors raised in the ocs-operator logs and rook-ceph-operator logs).

10. Modify the AWS security groups according to the ODF to ODF deployment doc.

11. Check that all the pods are up and running. 
12. Check that the storagecluster is Ready and Cephcluster health is OK:
$ oc get storageclusters.ocs.openshift.io
NAME                 AGE   PHASE   EXTERNAL   CREATED AT             VERSION
ocs-storagecluster   28m   Ready              2023-08-21T14:22:02Z   4.13.2
$ oc get cephclusters.ceph.rook.io 
NAME                             DATADIRHOSTPATH   MONCOUNT   AGE   PHASE   MESSAGE                        HEALTH      EXTERNAL   FSID
ocs-storagecluster-cephcluster   /var/lib/rook     3          19m   Ready   Cluster created successfully   HEALTH_OK              80c2f59c-8f2d-4cab-9365-d5cc379228a5


13. Check the of the ocs-operator logs, and the rook-ceph-operator logs and see there are no errors(You may need to restart the rook-ceph-operator pod, if you see errors in the rook-ceph-operator logs):
$ oc logs ocs-operator-858f54566c-5ghm8 | tail -n 2
{"level":"info","ts":"2023-08-21T15:15:10Z","logger":"controllers.StorageCluster","msg":"Reconciling metrics exporter service","Request.Namespace":"openshift-storage","Request.Name":"ocs-storagecluster","NamespacedName":{"namespace":"openshift-storage","name":"ocs-metrics-exporter"}}

14. Check the service and see that the provider server is NodePort as this is the default value:
$ oc get service
NAME                   TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)             AGE

15. Edit the ocs-storagecluster and change the value of "providerAPIServerServiceType" to LoadBalancer. Check the pods again and verified they are running.
Check again that the storagecluster is Ready and Cephcluster health is OK.


16. Check the service type again:
$ oc get service
NAME                   TYPE           CLUSTER-IP       EXTERNAL-IP                                                               PORT(S)             AGE

17. Edit the ocs-storagecluster and change the value of "providerAPIServerServiceType" to a dummy value "foo". Check the ocs-operator logs and see the expected error: 
$ oc logs ocs-operator-858f54566c-5ghm8 | tail -n 1
{"level":"error","ts":"2023-08-21T15:22:21Z","msg":"Reconciler error","controller":"storagecluster","controllerGroup":"ocs.openshift.io","controllerKind":"StorageCluster","StorageCluster":{"name":"ocs-storagecluster","namespace":"openshift-storage"},"namespace":"openshift-storage","name":"ocs-storagecluster","reconcileID":"3b9222e9-f8dd-4db8-ba2e-2b017f29be3b","error":"providerAPIServer only supports service of type NodePort and LoadBalancer","stacktrace":"sigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).reconcileHandler\n\t/remote-source/app/vendor/sigs.k8s.io/controller-runtime/pkg/internal/controller/controller.go:329\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).processNextWorkItem\n\t/remote-source/app/vendor/sigs.k8s.io/controller-runtime/pkg/internal/controller/controller.go:274\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).Start.func2.2\n\t/remote-source/app/vendor/sigs.k8s.io/controller-runtime/pkg/internal/controller/controller.go:235"}

Also, I checked the Cephcluster and saw the error status:
$ oc get storageclusters.ocs.openshift.io

18. Edit the ocs-storagecluster and change the value of "providerAPIServerServiceType" to NodePort. Check the service again (Also check again that the storagecluster is Ready and Cephcluster health is OK):
$ oc get service

19. Edit the ocs-storagecluster and change the value of "providerAPIServerServiceType" to LoadBalancer. Check the service again (Also check again that the storagecluster is Ready, Cephcluster health is OK, and ocs-operator logs looks fine):
$ oc get service
