Kubernetes is the world’s leading container orchestration platform. Its cloud agnostic status enables you to manage your workloads with ease, whether they reside in the cloud or on-premises. It has reduced the necessity of being locked into services provided by a cloud provider as well as the need for an entire operations team to manage large workloads on-premises on virtualization platforms. Because Kubernetes is so useful and popular today, having the skills to work in this platform is critical in the DevOps world. This article presents a number of resources, organized by topic, intended to help you learn Kubernetes or brush up on your K8s skills.
