How To Set Up a Private Docker Registry

[Docker Registry](https://docs.docker.com/registry/#what-it-is) is an application that manages storing and delivering Docker container images. Docker images guarantee consistent runtime environment through virtualization, but building an image can take time— registries centralize container images and reduce build times.In this tutorial, you’ll set up and secure your own private Docker Registry using [Docker Compose](https://docs.docker.com/compose/) and Nginx. Then, you’ll be able to push custom Docker images to your private registry and pull the image securely from a remote server. Choose your operating system to get started.
