@philipp1992

1. what was the exact set command used? I think the above command shared would have resulted in some error due to the -n namespace in between the value list ?
2. Was the helm charts deployed directly or were there any modifications done say in RBAC?
3. Also can you share the complete CIC logs?

[philipp1992]

yeah that command was wrong but i corrected it. with openshift SDN its working, openshift OVN failing

[apoorvak-citrix]

@philipp1992 will you be able to share the following details:

1. complete CIC logs.
2. The clusterrole created by the helm for this deployment, it should be prefixed by the name provided during helm install?

@philipp1992 For OVN CNI we rely on the following two annotations on the nodes to fetch the required podCIDR and gatewayIP to add the routes on the ADC.

podcidr Annotation : k8s.ovn.org/node-subnets
gateway Annotation: "k8s.ovn.org/node-primary-ifaddr

This is failing for the following two-nodes 10.x.x.42 and 10.x.x.12. can you confirm that it's present on these nodes?

[burkhat]

@apoorva-05 I'm a colleague from philipp and this nodes are Windows Nodes and they doens't have this annotations. Does the citrix-ingress-controller supports windows nodes?

annotations: csi.volume.kubernetes.io/nodeid: >- {"csi.vsphere.vmware.com":"422467f7-5d34-78c4-fd35-44e239e1ee06","smb.csi.k8s.io":"chmuw-default-windows-62q8n"} k8s.ovn.org/hybrid-overlay-distributed-router-gateway-mac: 00-15-5D-87-C3-B7 k8s.ovn.org/hybrid-overlay-node-subnet: 100.124.5.0/24 machine.openshift.io/machine: openshift-machine-api/chmuw-default-windows-62q8n volumes.kubernetes.io/controller-managed-attach-detach: 'true' windowsmachineconfig.openshift.io/pub-key-hash: 5436e7a8bcc02d332f30075cfa499abae2711bce4cf5e7765ab62d1f9c104efc windowsmachineconfig.openshift.io/version: 4.0.1+f66f0980

[philipp1992]

we have added the annotations to all nodes but still get the same error. cic2.txt

@philipp1992 we need to validate Citrix Ingress controller support on windows based OpenShift 4.9 cluster. Can we engage further over slack channel to know more about your use case and assist you further. Here is the email id AppModernization@citrite.net where you can share your email id to create slack channel.

[philipp1992]

seems like the email is incorrect [AppModernization@citrite.net](mailto:AppModernization@citrite.net)

[mayurmohanpatil]

@philipp1992 in case you are not able to send us an email, please use https://podio.com/webforms/22979270/1633242 invite to share your details where I can create slack channel for you.
