Digitalocean kubectl is the official command-line tool for connecting to and interacting with the cluster in Kubernetes.

Bobcares, as part of our Digitalocean managed service, responds to all inquiries, large or small.

Let’s take a closer look at Digitalocean kubectl.

Digitalocean kubectl

DigitalOcean Kubernetes is a managed Kubernetes service that allows us to deploy Kubernetes clusters without having to manage the control panel and containerized infrastructure. Clusters work with standard Kubernetes tool chains and natively integrate with DigitalOcean Load Balancers and block storage volumes.

DigitalOcean Kubernetes clusters are typically managed locally or remotely via a management server. In any case, the management machine requires two things:

• To connect to and interact with the cluster, use kubectl, the official Kubernetes command-line tool.

  The Kubernetes project provides instructions for installing kubectl on various platforms. Use kubectl version to verify that our installation is working and that our cluster is within one minor version.
• To manage config files and set context, use doctl, the official DigitalOcean command-line tool.

Obtain a Token or Certificate of Authentication.

To connect, we must first create a cluster and then add an authentication token or certificate to the kubectl configuration file.

Generate Using doctl.

• Firstly, use the following command to configure authentication from the command line, substituting the name of our cluster.

  doctl kubernetes cluster kubeconfig save use_our_cluster_name
• This downloads the cluster’s kubeconfig, merges it with any existing configuration from ~/.kube/config, and takes care of the authentication token or certificate automatically.

  When using recent versions of Kubernetes and doctl, this automatically generates a revocable OAuth token, and when using legacy versions, it automatically renews a certificate.

Download from the Control Panel

We can also manually download a cluster configuration file from the control panel.

1. Firstly, click on the Cluster’s name.
2. Then go to the Overview tab.
3. Then, click Download Config File in the Configuration section to get the kubeconfig file.
4. Name the file as -kubeconfig.yaml.
5. Finally, put this file in the ~/.kube directory and use the --kubeconfig flag to pass it to kubectl.

Connect to the Cluster

We can use kubectl to create, manage, and deploy clusters once the cluster configuration file is in place. We can also add DigitalOcean Load Balancers and block storage volumes to our cluster from this point.
