• From Rancher UI, in
local
cluster, I would look at the logs of rancher pods in cattle-system namespace • Ports to open are listed in https://ranchermanager.docs.rancher.com/getting-started/installation-and-upgrade/installation-requirements/port-requirements • If you have access to the downstream clusters (SSH on the nodes), I would look at the logs of cattle-cluster-agent in
cattle-system
namespace
b
rancher pods logs
cattle-cluster-agent pod logs:
rancher-webhook pod:
2. all network access seems to be open
3. on the downstream cluster cattle-cluster-agent pod has no errors
b
There is a process running on the downstream nodes called rancher-system-agent. It is configured to check the probes you’ve mentioned and report their status back to Rancher via a secret. You can check the downstream nodes to ensure that process is running and check its logs.
b
rancher-system-agent.service does not have any errors, restarting it does not help as well
