Description

Learn Kubernetes and prepare yourself for CKA and CKAD certifications. This course helps you gain the knowledge required to design and deploy cloud-native applications on a Kubernetes cluster. All you need is a good understanding of the Docker fundamentals to get started.

Kubernetes is at the cutting-edge of application deployment. To elevate your DevOps career, learn how to effectively deploy applications on Kubernetes. In this course, you will learn most of the things that everyone is looking for. This course will help you in understanding the production environment and we have captured most of the things in the course that you will face in an interview and while working in production. For example, what are the options we can use to create a cluster like Kubeadm, KOPS, Rancher, K3s, and EKS? We have almost covered everything, from installation to deploying the applications and securing them. Backing up your application is the most essential thing you need to do, which has also been covered here. By the end of this course, you will have gained the knowledge required to design and deploy cloud-native applications on a Kubernetes cluster.
