![]() Names are case sensitive.Īre additional options that can be global or command-specific, e.g., -o or -output to specify the output format. If omitted, kubectl returns all resources of the specified type, e.g., kubectl get pods returns all pods. Resource types are case sensitive and can be specified as singular, plural, or abbreviated, e.g., po for pod. ![]() What do you need to know about Kubectl?īefore we jump into specific kubectl commands, let’s get a basic understanding of the syntax and parameters of the kubectl command to understand each component.ĭescribes the action you want to perform on one or more resources, e.g., get, describe, create, apply.ĭescribes the resource type, which can be a Kubernetes-defined resource, e.g., a service, a pod, or a custom resource. Several commands also offer flags for specifying additional global or specific options. With kubectl commands, you can get details and perform operations on Kubernetes clusters, nodes, running pods, containers, and deployments. Kubectl makes it easier to perform Kubernetes functions or tasks on clusters and resources. While it’s possible to manually issue HTTP requests to the Kubernetes API, the process can be slow and cumbersome. Since the Kubernetes API is an HTTP REST API, it exposes all operations as endpoints that can be executed via an HTTP request. You can use kubectl commands to create, update, or delete Kubernetes objects, making interacting with the Kubernetes environment much simpler. Why Kubectl is importantĪs mentioned, Kubectl makes it easier to manage, maintain, and troubleshoot Kubernetes clusters. This guide will look at how best to integrate the most common and useful kubectl commands into your workflows, as well as provide some helpful tools for further optimization. It makes it easier to use the Kubernetes API and manipulate Kubernetes resources, allowing you to control Kubernetes clusters and run commands to deploy applications, manage cluster resources, and view logs. Try learning something new by reading our posts about open source log aggregators or use cases for Elasticsearch if you enjoyed this cheat sheet covering the most useful Linux commands.Kubectl is the default command-line tool for Kubernetes. ![]() The Logit.io platform offers a 14-day free trial to give you a taste of launching compliant, horizontally scalable observability stacks for Kubernetes monitoring if you are considering a new observability solution. The Kubernetes cluster and applications maintain detailed logs of every event, which can be used to narrow down the root causes of failures. Using logs when troubleshooting your Kubernetes cluster and applications is vital. You can share this via Twitter, LinkedIn, and Reddit. If you think anyone on your team would benefit from learning some of the most essential Kubernetes commands, please save the sheet below and share it with them. To assist you with understanding the most common kubectl commands & plugins, we've created a cheat sheet as a reference for operations engineers, software engineers, and cloud infrastructure managers who use Kubernetes primarily. Despite its simplicity in some respects, it has also introduced new levels of complexity in the deployment and management of distributed applications and services. In the world of container orchestration, Kubernetes has become the de facto standard.
