In this chapter, you learned how the Docker ecosystem provides an infrastructure for storing and sharing container images using Docker Registry. The concepts of the image registry and automated cloud builds have been demonstrated using a public Docker Hub and a private Azure Container Registry, which you set up from scratch using the Azure CLI. You also learned about the best practices for tagging and versioning images using the semantic versioning scheme. Finally, you were introduced to ensuring image integrity using Docker Content Trust (DCT).
In the next chapter, we are going to perform our first deep dive into the Kubernetes ecosystem in order to understand some key concepts and how they currently fit Windows containers support.
