See Kubernetes leader election how to retrieve the current leader. Only the current leader will log the performed actions.

Note: If you added multiple nodes with the controlplane role, both kube-controller-manager and kube-scheduler use a leader election process to determine the leader. docker ps -a -f=name='kube-apiserver|kube-controller-manager|kube-scheduler'Įxample output: CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESĢ6c7159abbcc rancher/hyperkube:v1.11.5-rancher1 '/opt/rke-tools/en.' 3 hours ago Up 3 hours kube-apiserverį3d287ca4549 rancher/hyperkube:v1.11.5-rancher1 '/opt/rke-tools/en.' 3 hours ago Up 3 hours kube-schedulerīdf3898b8063 rancher/hyperkube:v1.11.5-rancher1 '/opt/rke-tools/en.' 3 hours ago Up 3 hours kube-controller-manager The duration shown after Up is the time the container has been running. There are three specific containers launched on nodes with the controlplane role: Check if the Controlplane Containers are Running See the Kubernetes docs for more details.This section applies to nodes with the controlplane role. If two or more are marked as default, each PersistentVolumeClaim must explicitly Note: At most one storage class should be marked as default. To provision PersistentVolumes, we have to ensure that theĭesired storage classes have been created in the cluster. SSDs, along with network backed storage such as NFS, iSCSI, and CephFS.

The full code for this stack is on GitHub. See the official Kubernetes docs for more details. Their managed offering, Google Kubernetes Engine (GKE), offers an While it is possible to provision and manage a cluster manually on GCP, In order to run container workloads, you will need a Kubernetes cluster.
