You will create a Kubernetes cluster that adheres to best practices from scratch using the
kubeadm cluster bootstrapping utility. You will also perform several cluster management tasks including performing a backup the cluster, restoring the cluster from a backup, and upgrading Kubernetes in this Lab. You will also learn how to perform tests to verify that everything works as you expect. Even if you intend to use fully-managed Kubernetes clusters, this Lab provides you with a deeper understanding of Kubernetes clusters, and helps you decide on the cluster configuration that is best for your requirements.
This Lab is valuable to anyone working with Kubernetes, and has been prepared with the topics described in the Certified Kubernetes Administrator (CKA) Exam Curriculum. Completion of the Lab will help you get hands-on experience, which is essential for passing the CKA exam.
Upon completion of this Lab, you will be able to:
- Install Kubernetes master and worker nodes including TLS bootstrapping
- Implement backups and restore methodologies
- Perform Kubernetes cluster upgrades
- Test Kubernetes clusters
- Evaluate different Kubernetes cluster configurations
You should be familiar with:
- Working with Kubernetes to deploy applications
- Working at the command line in Linux
The following Labs can be used to fulfill the prerequisites to this Lab:
