If you have OS X 10.7 (Lion) or above, click Go, hold down the OPTION key and choose Library. On the Go menu, click Home > Library. Follow these steps to reset them: Quit all programs.
![]() Directory Repair .Exe For WindowsOpen Terminal, change directory to the location of the RKE binary, and then run one of the commands below.The file is already an executable. Windows (64-bit): rke_windows-amd64.exeCopy the RKE binary to a folder in your $PATH and rename it rke (or rke.exe for Windows) # macOSMake the RKE binary that you just downloaded executable. You can click on the release notes link to go straight to that release or manually navigate to our RKE Releases page and download the latest available RKE installer applicable to your operating system and architecture:Be aware that the release that is marked as Latest release on GitHub release page might not be the actual latest available release of RKE. Interacting with your Kubernetes ClusterFrom your workstation, open a web browser and look up the latest available RKE release. Creating the Cluster Configuration FileThere are many configuration options that can be set in the cluster.yml. Creating the Cluster Configuration FileRKE uses a cluster configuration file, referred to as cluster.yml to determine what nodes will be in the cluster and how to deploy Kubernetes. You can use any Linux you want, as long as you can install Docker on it.For information on which Docker versions were tested with your version of RKE, refer to the terms of service for installing Rancher on RKE.Review the OS requirements and configure each node appropriately. $ chmod +x rkeConfirm that RKE is now executable by running the following command: $ rke -versionRKE can also be installed and updated using Homebrew, a package manager for macOS.Using brew, install RKE by running the following command in a Terminal window: $ brew install rkeIf you have already installed RKE using brew, you can upgrade RKE by running: $ brew upgrade rkeRKE can also be installed and updated using MacPorts, a package manager for macOS.Using port, install RKE by running the following command in a Terminal window: $ port install rkeIf you have already installed RKE using port, you can upgrade RKE by running: $ port upgrade rkePrepare the Nodes for the Kubernetes clusterThe Kubernetes cluster components are launched using Docker on a Linux distro. Enable flash for macRke config -empty -name cluster.ymlInstead of creating a file, you can print the generated configuration to stdout using the -print flag. Rke config -name cluster.ymlYou can create an empty template cluster.yml file by specifying the -empty flag. See cluster configuration options for details on the various options. This command will prompt you for all the information needed to build a cluster. Using rke config to query for all the information needed.Run rke config to create a new cluster.yml in the current directory. Using our minimal cluster.yml and updating it based on the node that you will be using. This command assumes the cluster.yml file is in the same directory as where you are running the command. Deploying Kubernetes with RKEAfter you’ve created your cluster.yml, you can deploy your cluster with a simple command. After the Kubernetes cluster is deployed, you can manage these auto-generated certificates. You can also use custom certificates. CertificatesBy default, Kubernetes clusters require certificates and RKE auto-generates the certificates for all cluster components. RKE will deploy master components on all of these nodes and the kubelets are configured to connect to 127.0.0.1:6443 by default which is the address of nginx-proxy service that proxy requests to all master nodes.To create an HA cluster, specify more than one host with role controlplane. ![]() It is required to keep this file in order to update the cluster or perform any operation on it through RKE.Before v0.2.0, RKE saved the Kubernetes cluster state as a secret. Rkestate file contains the current state of the cluster including the RKE configuration and the certificates. Rkestate file in the same directory that has the cluster configuration file cluster.yml. Kubernetes Cluster StateThe Kubernetes cluster state, which consists of the cluster configuration file cluster.yml and components certificates in Kubernetes cluster, is saved by RKE, but depending on your RKE version, the cluster state is saved differently.As of v0.2.0, RKE creates a. Interacting with your Kubernetes clusterAfter your cluster is up and running, you can start using the generated kubeconfig file to start interacting with your Kubernetes cluster using kubectl.
