KUBECTL GET CONTEXTS HOW TO

Each cluster contains details about the URL for the Kubernetes API server (where the cluster accepts commands from kubectl), certificate authority, and a name to identify the cluster.

Clusters: This section lists all the clusters that you have access to.

Typically, there are three parts to a kubeconfig:

Let’s take a look at a cross section of a typical kubeconfig structure to see how cluster, user, and context tie up together. The Kubernetes API server itself does not recognize context the way it does other objects such as pods, deployments, or namespaces. It’s important to understand that a Kubernetes context only applies to the client side. In Kubernetes, a context is an entity defined inside kubeconfig to alias cluster parameters with a human-readable name.

KUBECTL GET CONTEXTS HOW TO

In this article, you will take a closer look at how kubeconfig is structured, how to define contexts in kubeconfig, and how to effectively use set-context to manipulate different contexts. This can be done with the kubectl config set-context command. To use that command, though, you need to configure contexts in your kubeconfig. You can quickly switch between clusters by using the kubectl config use-context command. This allows you to define multiple contexts in your configuration file, which you can then use to target multiple Kubernetes clusters, or the same cluster with a different set of users or namespaces. You can think of Kubernetes contexts as a kind of shortcut that allows you to access cluster, user, and namespace parameters conveniently. This is where Kubernetes contexts come into the picture. Combined with multiple clusters, every kubectl command is going to look something like kubectl -namespace -kubeconfig …, which is both time consuming and an easy place for errors to slip in. If your clusters have multiple namespaces, another pain point appears: the need to specify -namespace or -n every time you use kubectl. If you are working with multiple Kubernetes clusters, it can quickly become cumbersome to manage configuration files like this as you are switching from one cluster to the other. # export KUBECONFIG=path1:path2:path3 # kubectl get pods This environment variable allows you to specify multiple kubeconfig files by setting the value to the paths of the files, delimited by colons: The final option is to use the KUBECONFIG environment variable.If your kubeconfig is located somewhere other than the default path, you can specify it with this flag and issue commands: Another option is to use the flag -kubeconfig.One option is to place the kubeconfig file in $HOME/.kube/config, which is the default path kubectl looks for.The first time you configure kubectl, you need to place kubeconfig in the correct location before you can pass the commands to your Kubernetes cluster. Also, will try to cover some examples and best practices for better understanding. In Kubernetes there is more number of tools, in this articles let’s check about kubectl set-context. It is important to have better way to manage it. Kubectl knows where to look for your cluster configuration.Currently or in future, we will be going to manage more number of Kubernetes clusters.
