In this chapter, we'll discuss how to make changes to the infrastructure that powers your Kubernetes infrastructure, whether or not it is a purely public cloud platform or a hybrid installation. We'll discuss methods for handling underlying instance and resource instability, and strategies for running highly available workloads on partially available underlying hardware. We'll cover a few key topics in this chapter in order to build your understanding of how to manage infrastructure in this way:
- How do we plan to deploy Kubernetes components?
- How do we secure Kubernetes infrastructure?
- How do we upgrade the cluster and kubeadm?
- How do we scale up the cluster?
- What external resources are available to us?
In this chapter, you'll learn about the following:
- Cluster upgrades
- How to manage kubeadm
- Cluster scaling
- Cluster maintenance
- The SIG Cluster Lifecycle group
