The required CLI utility for working with Kubernetes clusters. Set which Kubernetes cluster kubectl communicates with and modifies configuration information. Kubectl config unset users.foo # delete user foo Not to mention, there is bash/zsh completion. and then switch to a context easily: kubectx eu. kubectx can create aliases for your long context names: kubectx eugkeahmetb-samples-playgroundeurope-west1-bdublin. Kubectl config set-context gce -user=cluster-admin -namespace=foo \ Here is what kubectx has to offer: kubectx remembers your context switches, you can switch to the previous contexts with: kubectx. # set a context utilizing a specific username and namespace. Kubectl config set-context -current -namespace=ggckad-s2 # permanently save the namespace for all subsequent kubectl commands in that context. Kubectl config set-credentials kubeuser/ -username=kubeuser -password=kubepassword # add a new cluster to your kubeconf that supports basic auth Kubectl config use-context my-cluster-name # set the default context to my-cluster-name Kubectl config current-context # display the current-context Kubectl config get-contexts # display list of contexts Kubectl config view -o jsonpath='' # get a list of users Kubectl config view -o = "e2e")].user.password}' KUBECONFIG=~/.kube/config:~/.kube/kubconfig2 # use multiple kubeconfig files at the same time and view merged config Initial Config Autocomplete Bash source > ~/.bashrc # add autocomplete permanently to your bash shell.Ĭontext and Configuration kubectl config view # Show Merged kubeconfig settings. KUBECONFIG environment variable, append it to your KUBECONFIG environment variable now.The required CLI utility for working with Kubernetes clusters. If you have a $HOME/.kube/config file, and it's not already listed in your Append $HOME/.kube/config to your KUBECONFIG environment variable Brieflyįamiliarize yourself with the contents of these files. There might also be other configuration files in this directory. ![]() Go to $HOME/.kube, and see what files are there. The cluster, then you probably have a file named config in the $HOME/.kube If you already have a cluster, and you can use kubectl to interact with Organizing Cluster Access Using kubeconfig Files Explore the $HOME/.kube directory User to access the frontend namespace of the development cluster".įor more information about how kubeconfig files are merged, see For example, theĭev-frontend context says, "Use the credentials of the developer Sometimes you may want to use Base64-encoded data embedded here instead of separateĬertificate files in that case you need add the suffix -data to the keys, for example,Ĭertificate-authority-data, client-certificate-data, client-key-data.Įach context is a triple (cluster, user, namespace). This command will create a context based on a username. kubectl config get-contexts Create a New Context Here, we have constructed a context because there is not one that can be used for switching. Of certificate files in your environment. The following command is used in a kubeconfig file to list all the contexts. You need change these to the actual pathnames Listing contexts: kubectl config get-contexts. Each context contains a Kubernetes cluster, a user, and a namespace. The fake-ca-file, fake-cert-file and fake-key-file above are the placeholdersįor the pathnames of the certificate files. A context is a group of access parameters. In yourĬonfig-exercise directory, create a file named config-demo with this content: To the scratch cluster requires authentication by username and password.Ĭreate a directory named config-exercise. Access to the development cluster requires authentication by certificate. In your scratch cluster,ĭevelopers work in the default namespace, or they create auxiliary namespaces as they In the development cluster, your frontend developers work in a namespace called frontend,Īnd your storage developers work in a namespace called storage. Suppose you have two clusters, one for development work and one for scratch work. The kubectl version should beĬluster's API server. To check that kubectl A command line tool for communicating with a Kubernetes API server. Or you can use one of these Kubernetes playgrounds: You need to have a Kubernetes cluster, and the kubectl command-line tool mustīe configured to communicate with your cluster. It does not mean that there is a file named kubeconfig. This is a generic way of referring to configuration files. Note: A file that is used to configure access to a cluster is sometimes called a kubeconfig file.
