In the Configuration section, click Download Config File to download its kubeconfig file. There is also a cluster configuration file you can download manually from the control panel.Ĭlick the name of the cluster to go to its Overview tab.
Kubectl list contexts Patch#
You can upgrade Kubernetes clusters to newer patch versions and minor versions to use tokens instead. With legacy versions of doctl or Kubernetes, this creates a certificate that is valid for seven days, renews automatically, and cannot be revoked. You can view and revoke this token in the Applications & API section of the control panel.Īutomatic certificate renewal. If you meet the version requirements listed above, Recent versions of Kubernetes and doctl, and automatically renews a
Under the hood, this automatically generates a revocable OAuth token when using This downloads the kubeconfig for the cluster, merges it with any existing configuration from ~/.kube/config, and automatically handles the authentication token or certificate. To configure authentication from the command line, use the following command, substituting the name of your cluster.ĭoctl kubernetes cluster kubeconfig save use_your_cluster_name Version of doctl, you will be granted a certificate instead. If you are not running these versions of Kubernetes, or are using a legacy

(If using doctl, as recommended, you must also have When connecting to these Kubernetes versions, generating credentials creates a Version requirements for obtaining tokens Get an Authentication Token or CertificateĪfter creating a cluster, you need to add an authentication token or certificate to your kubectl configuration file to connect. The doctl GitHub repo has instructions for installing doctl. Use kubectl version to veirfy that your installation is working and within one minor version of your cluster.ĭoctl, the official DigitalOcean command-line tool, to manage config files and set context. The Kubernetes project provides installation instructions for kubectl on a variety of platforms. Kubectl, the official Kubernetes command-line tool, to connect to and interact with the cluster. In either case, the management machine needs two things: Clusters are compatible with standard Kubernetes toolchains and integrate natively with DigitalOcean Load Balancers and block storage volumes.ĭigitalOcean Kubernetes clusters are typically managed from a local machine or sometimes from a remote management server. You can verify your current context by doing the following: master $ kubectl config current-contextĪt this point, all requests we make to the Kubernetes cluster from the command line are scoped to the production namespace.DigitalOcean Kubernetes (DOKS) is a managed Kubernetes service that lets you deploy Kubernetes clusters without the complexities of handling the control plane and containerized infrastructure. use below command to switch into prod context. If you want to operate in the production namespace.
You can now view the contexts and alternate against the two new request contexts depending on which namespace you wish to work against. By default, the above commands adds two contexts that are saved into file. You can alternate against depending on what namespace you wish to work against. The above commands will create two new contexts. Kubectl config set-context prod -namespace=production -cluster=lithe-cocoa-92103_kubernetes -user=lithe-cocoa-92103_kubernetes This section sets our default cluster, namespace and user that kubectl will use with its commands.Ĭretae New Context: kubectl config set-context dev -namespace=development -cluster=lithe-cocoa-92103_kubernetes -user=lithe-cocoa-92103_kubernetes In the above command output you can see contexts section. This file also stores authentication information such as username/passwords, certificates or tokens. you can find this same info in $HOME/.kube/KUBECONFIG OR $HOME/.kube/config file. It will give you current context configuration. View Context Configuration master $ kubectl config view It will display the current context which you are using. Kubectl config current-context master $ kubectl config current-context To know what is the current context or To view the current context use below command
