In this chapter, we learned how to secure secrets in Kubernetes. We went into detail in creating, decoding, and using secrets. We installed and injected Istio, achieving the goal of being able to set system-wide policies without needing developer intervention or oversight. Since hackers like to pick on easy systems, the skills that we have learned in this chapter will help to make your setup less likely to be targeted. In the next chapter, you will learn how to deploy serverless functions on AKS.
