![]() You can still access the deregistered cluster in the same way you did before you registered it. The cluster remains live, although it's no longer in Rancher. When you delete a registered cluster through Rancher, the Rancher server disconnects from the cluster. When you create an EKS, AKS, or GKE cluster in Rancher, then delete it, Rancher destroys the cluster. However, Rancher doesn't destroy registered clusters when you delete them through the Rancher UI. Rancher handles registered EKS, AKS, or GKE clusters similarly to clusters created in Rancher. The ability to see a read-only version of the K3s cluster's configuration arguments and environment variables used to launch each node in the clusterĪdditional Features for Registered EKS, AKS, and GKE Clusters The ability to configure the maximum number of nodes that will be upgraded concurrently Upgrading an imported cluster outside of Rancher is not supported. Active clusters are assigned two Projects: Default (containing the namespace default) and System (containing the namespaces cattle-system, ingress-nginx, kube-public and kube-system, if present).Īfter a cluster has been imported into Rancher, upgrades should be performed using Rancher.You can access your cluster after its state is updated to Active.Rancher is deploying resources to manage your cluster. Your cluster is registered and assigned a state of Pending.When you finish running the command(s) on your node, click Done.Then run the command on a node where kubeconfig is configured to point to the cluster you want to import. To work around this validation, copy the command starting with curl displayed in Rancher to your clipboard. If you are using self-signed certificates, you will receive the message certificate signed by unknown authority.If you are unsure it is configured correctly, run kubectl get nodes to verify before running the command shown in Rancher. Copy the kubectl command to your clipboard and run it on a node where kubeconfig is configured to point to the cluster you want to import.The prerequisite for cluster-admin privileges is shown (see Prerequisites above), including an example command to fulfil the prerequisite.Users can select the Project Network Isolation option under the Advanced Options dropdown to do so. Enable Project Network Isolation to ensure the cluster supports Kubernetes NetworkPolicy resources. If rancher agent requires use of proxy to communicate with Rancher server, HTTP_PROXY, HTTPS_PROXY and NO_PROXY environment variables can be set using agent environment variables.ī. The environment variables can be set using key value pairs. Click Agent Environment Variables under Cluster Options to set environment variables for rancher cluster agent. If you are importing a generic Kubernetes cluster in Rancher, perform the following steps for setup:Ī.Use the Role drop-down to set permissions for each user. Click Add Member to add users that can access the cluster. Use Member Roles to configure user authorization for the cluster.EKS Clusters ĮKS clusters must have at least one managed node group to be imported into Rancher or provisioned from Rancher successfully. For details, refer to Configuring a K3s cluster to enable importation to Rancher. ![]() If you are registering a K3s cluster, make sure the cluster.yml is readable. To learn more about role-based access control for GKE, please see the official Google documentation. Since, by default, Google Kubernetes Engine (GKE) doesn't grant the cluster-admin role, you must run these commands on GKE clusters before you can register them. Before running the kubectl command to register the cluster.
