Try looking in the following places to identify what is the issue with kube-proxy: To identify why, run the command journalctl -u kubelet and examine the kubelet logs. inactive (dead) means the kubelet crashed.active (exited) means the kubelet was exited, probably in error.active (running) means the kubelet is actually operational, look for the problem elsewhere.To resolve a kubelet issue, SSH into the node and run the command systemctl status kubelet Check for hardware issues or misconfigurations and resolve them.Run a malware scan-there may be hidden malicious processes taking up system resources.If there are any, shut them down or reduce them to a minimum to conserve resources. Identify which non-Kubernetes processes are running on the node.Here are a few ways to resolve a system resource issue on the node: Resolving Node Not Ready Issues Resolving Lack of System Resources Run kubectl describe node and look in the Conditions section-if the NetworkUnavailable flag is True, this means the node has a connectivity issue. This could be due to a disconnected network cable, no Internet access, or misconfigured networking on the machine. Connectivity IssueĮven if a node is configured perfectly, but it has no network connectivity, Kubernetes treats the node as not ready. Run kubectl get pods -n kube-system to show pods belonging to the Kubernetes system. If kube-proxy stops running for any reason, the node goes into a not ready state. Kube-proxy runs on every node and is responsible for regulating network traffic between the node and other entities inside and outside the cluster. Run kubectl describe node and look in the Conditions section-if all the conditions are unknown, this indicates the kubelet is down. If the kubelet crashes or stops on a node, it cannot communicate with the API server and the node goes into a not ready state. The kubelet must run on each node to enable it to participate in the cluster. Why It Prevents the Node from Running Pods PIDPressure-node is running too many processes. MemoryPressure-node is running out of memory.ĭiskPressure-node is running out of disk space. If a note is in the NodeReady state, it indicates that the kubelet is installed on the node, but Kubernetes has detected a problem on the node that prevents it from running pods.
