Containerize Your Applications in the ‘Kubernetes Way’
Kubernetes is a powerful tool developed by Google for managing containerized applications in a clustered environment. Kubernetes helps you automate, deploy, scale, and manage containerized applications. It gives you the freedom to take advantage of on-premise cloud infrastructures. It also helps you write better cloud-native applications. Kubernetes is a core tool in DevOps; it gives you the ability to schedule and manage containers (Docker or otherwise) at scale. If you’re looking to containerize your applications in the ‘Kubernetes Way’ then this Course is perfect for you!
This comprehensive 3-in-1 Course is a fast-paced guide offering hands-on and practical guidance with step-by-step instructions and assignments to Containerize Your Applications in the ‘Kubernetes Way’! You’ll initially get up and running with fundamentals of Kubernetes and container orchestration. You’ll build your own container cluster and manage it as well as secure the cluster and handle service discovery. Moving further, you’ll dive into the Kubernetes architecture, components and services to build a production-class container infrastructure. Finally, you’ll write cloud-native applications, test, monitor and deploy your application on the cloud (GCP) using Kubernetes.
By the end of this course, you’ll containerize your applications to build a production-class container infrastructure in the ‘Kubernetes way’.
Contents and Overview
This training program includes 3 complete courses, carefully chosen to give you the most comprehensive training possible.
The first course, Kubernetes in 7 Days, covers managing applications in a productionised Kubernetes. This course will help you to unravel the potential of Kubernetes in the shortest amount of time. You will begin by creating your first Kubernetes cluster using Minikube. Then move on to exploring Kubernetes in some more detail and build a complex cluster. By the 4th Day, you will learn to enhance your cluster with a Grafana based monitoring dashboard in your application. Once you’ve acquired knowledge on dashboards, explore how a Kubernetes cluster provisions storage to its applications and learn how to secure them. Finally, learn to create a CI/CD pipeline to build and deploy your applications.
The second course, Containerization the Kubernetes Way, covers developing, running, and deploying your containerized applications using Kubernetes. You’ll learn how to deploy Kubernetes on several cloud platforms. Further, you’ll learn to package your code to run in Kubernetes. You’ll dive into the Kubernetes architecture and components and explore how they come together to build a production-class container infrastructure. Later you will learn to work with pods, deployments, and services. By the end of this course, you’d have gained the required skills to deploy a Kubernetes cluster and a simple application in a development ecosystem.
The third course, Kubernetes for Developers, covers writing cloud-native applications that can run anywhere with the power of Kubernetes. This course will give you detailed instructions, real-world examples, and helpful advice. We will begin by learning to set up the development environment on your local machine. Then move on to package your code into Kubernetes, and manage container lifecycles. Once you get a grip on understanding the RBAC Authorization, very easily explore the monitoring techniques with Prometheus and troubleshoot your service account. Finally, you will learn to create a cluster in your Google Cloud Environment and deploy your application in production. By the end of this video, you will develop, run, test, and deploy your application in the cloud, utilizing the power of Kubernetes to its full potential.
By the end of this course, you’ll containerize your applications to build a production-class container infrastructure in the ‘Kubernetes way’.
