In this chapter, we looked at the emerging standards bodies in the container community and how they are using open specifications to shape the technology for the better. We looked at various container frameworks and runtimes. We dipped our toes into the CNCF, and tried out CRI-O.

We also took a closer look at CoreOS, a key player in both the container and Kubernetes community. We explored the technology that CoreOS is developing in order to enhance and complement container orchestration, and saw first-hand how to use some of it with Kubernetes. Finally, we looked at the supported enterprise offering of Tectonic and some of the features that are available now.

We also looked at some of the major PaaS offered by cloud service providers.

In the next chapter, we will explore the broader Kubernetes ecosystem and the tools available to move your cluster from development and testing into full-blown production.
