To see the current context we can use the command kubectl config current-context To set this file as kubeconfig use command: kubectl config -kubeconfig=config-demo use-context production-dev Current Contextīy default, the kubectl command-line tool uses parameters from the current context to communicate with the cluster. You can also define contexts to quickly and easily switch between clusters and namespaces.Ĭreate a file named config with content: apiVersion: v1 clusters: - cluster: certificate-authority: fake-ca-file server: name: production - cluster: insecure-skip-tls-verify: true server: name: staging users: - name: developer user: client-certificate: fake-cert-file client-key: fake-key-file - name: tester user: password: some-password username: tester contexts: - context: cluster: production namespace: spider user: developer name: production-dev - context: cluster: staging namespace: test user: tester name: staging-tester - context: cluster: staging namespace: default user: developer name: staging-developer current-context: '' kind: Config preferences: With kubeconfig files, you can organize your clusters, users, and namespaces. Contexts, bring together clusters and users under a friendly name.Each user definition has a friendly name, a username, and a set of credentials. Users, lets you define different users that might have different level of permissions on each cluster.Each cluster definition has a name, certificate information, and API server endpoint. Clusters, lets you define multiple clusters and is ideal if you plan on using a single workstation to manage multiple clusters.You can specify other kubeconfig files by setting the KUBECONFIG environment variable or by setting the -kubeconfig flag. Configurationįor configuration, kubectl looks for a file named config in the $HOME/.kube directory. It uses a configuration file to know which cluster and API server endpoint to POST to. In a broad view, kubectl converts user-friendly commands into the JSON payload required by the API server. It’s available for Linux, Mac, and Windows. In fact, it’s useful to think of kubectl as SSH for Kubernetes. Kubectl is the main Kubernetes command-line tool and is used for your Kubernetes management activities.
