SUSE, a leading open source innovator, acquired Rancher in 2020. The containers necessary to set up the cluster will then be launched using the Docker socket. After authenticating with the specified user and SSH private key and connecting to the host's Docker instance via the socket file, RKE will connect to the cluster hosts using a local SSH library (made accessible through SSH with socket forwarding). This means that all you need to install locally to start your cluster is the RKE binary. Like Rancher, RKE is developed in Golang and will speak to the nodes using the built-in libraries. RKE is utilised by Rancher internally, but it may also be used independently to build Kubernetes clusters. New users frequently believe that RKE will handle Rancher installation for them. You may run rke up and have RKE construct a Kubernetes cluster based on the information you gave in your setup by producing a straightforward YAML cluster configuration file, which is called cluster.yml by default. Rancher's command-line tool for setting up, maintaining, and updating Kubernetes clusters is known as RKE, or Rancher Kubernetes Engine. It quickly creates a cluster with a single command, and Kubernetes upgrades are atomic and safe because to its declarative setup. You can deploy and use Kubernetes with RKE as long as you can run a supported version of Docker. RKE makes it simple to automate Kubernetes' functioning, which is also totally independent of the platform and operating system you're using. By eliminating the majority of host requirements and providing a consistent path for deployment, upgrades, and rollbacks, it resolves the usual annoyance associated with Kubernetes installation complexity. Rancher Kubernetes Engine (RKE) is a fully Docker-based Kubernetes distribution that has received CNCF certification. Is this a possibility?Īny insight into what might have caused the issue or how I can resolve it would be greatly appreciated.In this article we will learn how to install RKE single node cluster. ![]() The unusual AGE shown in kubectl output makes me wonder if maybe rebooting the node before purging the Docker bits caused the node to attempt to re-register itself automatically. I have tried searching the forums but did not find anything that seemed relevant to my situation. ![]() docker logs shows the following message over and over again: ![]() command.ĭocker ps run on the node shows that the only container running is rancher/rancher-agent. The node shows as Unavailble in the Rancher UI with the error message “Kubelet stopped posting node status.” The Roles shown in Rancher UI match what I specified when attempting to re-add the node.įrom the command line kubectl get nodes also lists the node, but the ROLES are listed as and the AGE is about 15 minutes larger than it should be based on when I ran the docker run. Attempt to re-add the nodes ( docker run.Reboot the nodes again (last step of manual cleanup process).Run through the manual cleanup steps documented here.As described in this other thread, I am trying to re-add a node to my cluster after removing it.
