RE: Issues shown in subctl diagnose all

[Vaishnavi Rajulu]

Hi Guys,

I keep on having issues like this in both the clusters in subctl diagnose all. Can you help me how to resolve the issues.

 ✓ Globalnet deployment detected - checking that globalnet CIDRs do not overlap
 ✓ Checking DaemonSet "submariner-gateway"
 ✓ Checking DaemonSet "submariner-routeagent"
 ✓ Checking DaemonSet "submariner-globalnet"
 ✓ Checking DaemonSet "submariner-metrics-proxy"
 ✓ Checking Deployment "submariner-lighthouse-agent"
 ✓ Checking Deployment "submariner-lighthouse-coredns"
 ✓ Checking the status of all Submariner pods
 ✓ Checking that gateway metrics are accessible from non-gateway nodes
 ✓ Checking that globalnet metrics are accessible from non-gateway nodes

 ⚠ Checking Submariner support for the CNI network plugin
 ⚠ Submariner could not detect the CNI network plugin and is using ("generic") plugin. It may or may not work.
 ✗ Checking gateway connections
 ✗ Connection to cluster "cluster2" is not established. Connection details:

}
 ✓ Checking Submariner support for the kube-proxy mode
 ✓ The kube-proxy mode is supported
 ✓ Checking that firewall configuration allows intra-cluster VXLAN traffic
 ✓ Checking that Globalnet is correctly configured and functioning

 ✓ Checking that services have been exported properly

Skipping inter-cluster firewall check as it requires two kubeconfigs. Please run "subctl diagnose firewall inter-cluster" command manually.

subctl version: v0.18.0
