Kubernetes RBAC is a powerful feature that allows you to fine-tune access to resources in your cluster. By creating roles and role bindings, you can specify exactly which users and processes have access to which resources and actions. This can help you to secure your cluster and prevent unauthorized access to critical resources.
In this article we explore K3S, first made available in early 2019 as a lightweight option for Kubernetes (K8S). One of the issues with Kubernetes when it initially became available was that installing Kubernetes involved several commands to run and several configurations to make. Several managed services for Kubernetes emerged, mostly from cloud service providers. The cloud-managed services did simplify the task of spinning up a Kubernetes cluster, but issues relating to the complexities of running a cluster still remain.
As organizations continue to pursue their digital transformations, their IT infrastructures are expanding in both size and diversity. Many are seeing the addition of two new technologies in particular: containers and Kubernetes.
Containerization has replaced virtual machines to a great extent because containers are lightweight and make efficient use of the OS kernel. Docker’s efficient nature helps with software development, testing, delivery, and deployment in a DevOps environment, and all the benefits of Docker also apply to Kubernetes. Let’s explore some of the additional agile and DevOps benefits you can gain by using Kubernetes.
