Installing Intel SGX plugin on Red Hat Single Node Openshift #278

Closed veluruchaithanya closed 2 weeks ago

veluruchaithanya commented 2 weeks ago

Hi, I am trying to enable SGX secure enclaves on a server platform. This server supports Intel SGX and contains a 4th Gen Intel Xeon Scalable Processor. The below BIOS configuration update was done to enable SGX.

Socket Configuration -> Processor Configuration -> Memory Encryption (TME) -> Enabled
Socket Configuration -> Processor Configuration -> Total Memory Encryption (TME) Bypass -> Disabled
Socket Configuration -> Processor Configuration -> Total Memory Encryption Multi-Tenant(TME-MT) -> Enabled
Socket Configuration -> Processor Configuration -> SW Guard Extensions (SGX) -> Enabled
Socket Configuration -> Processor Configuration -> PRM Size for SGX -> 1GB

The Red Hat Single Node OpenShift Platform (SNO Cluster Version 4.14.23) was deployed on the server. After that, I installed the below versions of dependent operators on the Red Hat SNO cluster. NFD Operator Version: 4.14.0-202406180839 Intel Device Plugins Operator Version: 0.28.0

The dependent operator's versions are selected as per release table

While deploying the SGX plugin I got the below error

 $ oc get pods
NAME                                                    READY   STATUS    RESTARTS   AGE

$ oc apply -f https://raw.githubusercontent.com/intel/intel-technology-enabling-for-openshift/v1.2.1/device_plugins/sgx_device_plugin.yaml
Error from server (InternalError): error when creating "https://raw.githubusercontent.com/intel/intel-technology-enabling-for-openshift/v1.2.1/device_plugins/sgx_device_plugin.yaml": Internal error occurred: failed calling webhook "msgxdeviceplugin.kb.io": failed to call webhook: Post "https://inteldeviceplugins-webhook-service.inteldeviceplugins-system.svc:443/mutate-deviceplugin-intel-com-v1-sgxdeviceplugin?timeout=10s": service "inteldeviceplugins-webhook-service" not found

I looked if any pods are failing in the existing namespaces and I see below pod is failing in namespace cert-manager.

$ oc get pods -n cert-manager

Can someone help with troubleshooting this issue?

vbedida79 commented 2 weeks ago

Thanks for filing the issue. Is there any requirement for cert-manager on openshift? Would it be possible to delete the pod?

veluruchaithanya commented 2 weeks ago

Hi, I removed the cert-manager pods on openShift. I got the same error as earlier when installing the SGX device plugin.

vbedida79 commented 2 weeks ago

got it. could you check the result for this api

oc api-resources | grep MutatingWebhookConfiguration

veluruchaithanya commented 2 weeks ago

This is the result

vbedida79 commented 2 weeks ago

is cert-manager installed with an operator? would it be possible to uninstall the operator, that might delete all the associated resources

veluruchaithanya commented 2 weeks ago

I removed cert-manager pods earlier with below command and it removed all the associated resources for cert-manager operator.

$ oc delete deployment -n cert-manager -l app.kubernetes.io/instance=cert-manager

This procedure is mentioned in below link Uninstalling the cert-manager Operator for Red Hat OpenShift - cert-manager Operator for Red Hat OpenShift | Security and compliance | OpenShift Container Platform 4.14

veluruchaithanya commented 2 weeks ago

I found some CRD's and two services related to cert-manager operator and removed them manually. I tried to deploy sgx device plugin and got the same error as before.

veluruchaithanya commented 2 weeks ago

SGX device plugin error displays below information service "inteldeviceplugins-webhook-service" not found

I checked the intel related services running in the cluster and I only got one service and webhook service doesn't exist.

oc get service --all-namespaces | grep intel

NAMESPACE                                          NAME                                            TYPE           CLUSTER-IP       EXTERNAL-IP                            PORT(S)

Is there a command to install inteldeviceplugins-webhook-service on openshift?

vbedida79 commented 2 weeks ago

Yes, that is same.

oc get service --all-namespaces | grep intel
openshift-operators                                inteldeviceplugins-controller-manager-service

usually we don't install any webhook service for sgx device plugin on openshift could you please share the logs of intel device plugins controller manager pod? Is there any specific certification setup in your cluster as such?

I don't remember configuring any certificate setup in the cluster

chaitanya1731 commented 2 weeks ago

Hi @veluruchaithanya to get more info to debug, could you please check few things?

Does your cluster has the api version admissionregistration.k8s.io/v1? also make sure apiservice is present.

[ckulkar1@jfz1r09h07 ~]$ oc api-versions | grep admissionregistration
admissionregistration.k8s.io/v1
[ckulkar1@jfz1r09h07 ~]$ oc get apiservice | grep admission
v1.admissionregistration.k8s.io               Local                                                        True        3h48m
[ckulkar1@jfz1r09h07 ~]$

From the error you posted it seems like the cluster is trying to get the MutatingWebhookConfiguration from "admissionregistration.k8s.io/v1beta1". Take a note that the api-version is v1 and not v1beta1 as it was deprecated in k8s version 1.22. Refer here.

Once that is figured, can you please retry installing Certified Intel Device Plugins Operator? and make sure that the MutatingWebhookConfiguration is present? 

[ckulkar1@jfz1r09h07 ~]$ oc get MutatingWebhookConfiguration | grep sgx
msgxdeviceplugin.kb.io-mwb87            1          3m19s

veluruchaithanya commented 2 weeks ago

Hi @chaitanya1731, I ran the commands and got the same results as you mentioned

$ oc api-versions | grep admissionregistration
admissionregistration.k8s.io/v1

$ oc get apiservice | grep admission
v1.admissionregistration.k8s.io          Local            True        62d

$ oc get MutatingWebhookConfiguration | grep sgx
msgxdeviceplugin.kb.io-pktxg                        1          4m11s
sgx.mutator.webhooks.intel.com-gxjqj                1          4m11s

I fixed the v1beta1 version issue by deploying cert-manager with latest version v1.15.1 and cert-manager pod is not failing now

$ oc get pods  -n cert-manager

cert-manager-webhook-6cc8fdfd7-8m2tt       1/1     Running   0          19m

I still got error while deploying intel SGX device plugin

chaitanya1731 commented 2 weeks ago

Thanks. So the cert-manager and the api issue is resolved.. Just to make sure about the operator installation is correct, can you confirm if all the artifacts are installed in correct namespaces?for example.. Intel Device Plugins Operator in openshift-operators namespace, NFD operator and its nfd-discovery and nfd-rule yamls in openshift-nfd?

veluruchaithanya commented 2 weeks ago

Hi, I can confirm that all the artifacts are installed in the correct namespaces. I am displaying the output below.

Thanks. @veluruchaithanya We attempted to replicate this issue on both 4.14.30 and 4.14.31 but were unsuccessful. The SGX plugin worked correctly according to the given instructions.. It's worth noting that we do not utilize cert-manager for OpenShift. It appears that cert-manager may be causing misconfigurations on your OpenShift cluster, potentially causing some issues in the correct installation of the Intel Device Plugins Operator. I've observed that cert-manager has its own operator for OpenShift, which is different from the one installed on your cluster. Our Intel device plugins controller manager logs align with those you've shared, indicating that the operator installation appears correct. However, due to potential misconfigurations, it isn't functioning as expected. Could you please consider re-provisioning the cluster and following the same process again (without cert-manager) to see if the issues gets resolved?

Hi @chaitanya1731 Have you tried to replicate the issue on the single node openshift (SNO) cluster?

chaitanya1731 commented 2 weeks ago

Yes. We tried on SNO.

Hi, I removed the cert-manager and intel-device-plugins-operator. After that, I checked for old webhook plugins in the api-resources "MutatingWebhookConfiguration" and "ValidatingWebhookConfiguration". They had below webhooks

MutatingWebhookConfiguration

NAME                                                  WEBHOOKS   AGE

inteldeviceplugins-webhook                          1          15d
mutating-webhook-configuration                      9          16d

ValidatingWebhookConfiguration

NAME                                                  WEBHOOKS   AGE

validating-webhook-configuration                      7          16d

After removing above webhooks, I tried installing intel-device-plugins-operator and intel SGX device plugin. The SGX plugin has been successfully installed this time.

$ oc get pods

@chaitanya1731 @vbedida79 Thanks for help.

chaitanya1731 commented 2 weeks ago

Looks like it was some misconfiguration due to cert-manager. Thanks for confirming and happy to help. Closing this now.

chaitanya1731 commented 2 weeks ago

resolved

The device plugins "upstream" docs refer to cert-manager usage to get webhooks' TLS certs provisioned. However, that is not applicable to OpenShift because OLM takes care of that.

It sounds there is a potential error with cert-manager + OLM co-existence when setting up the Device Plugins operator.
