In the previous chapter, we briefly discussed Kubernetes concepts and the Kubernetes architecture, and the main differences between Kubernetes and Docker Swarm.
The goal of this chapter is to give you a basic understanding of an alternative container runtime technology for Kubernetes—CRI-O. This chapter provides a basic understanding of the Container Runtime Interface, Open Container Initiative, and CRI-O, and describes how to manage containers using that technology.
After reading this chapter, you will have a solid understanding of the following topics:
- The Container Runtime Interface and Open Container Initiative
- How CRI-O works with Kubernetes
- Installing and working with CRI-O
