Docker is a tool that can create, deploy, and run applications by using containers. A container is a standardized unit of software that includes everything needed to run an application: code, runtime, system tools, and system libraries. This guarantees that your application will always run the same and makes collaboration easy.

Docker containers are lightweight and portable because they don't need a separate operating system or virtual machine for each application. This makes them ideal for microservices, which are small, modular applications that are easy to develop, test, and deploy.

Docker containers are built from images. An image is a file that contains all the code, libraries, and dependencies needed to run an application. Images can be created and shared using a public registry such as Docker Hub.

To create a container, you first need to create an image. Images are created using a Dockerfile, which is a text file that contains instructions for how to build an image.

Once you have an image, you can use the docker run command to create a container from that image. The docker run command takes the image and creates a container from it. The container is a running instance of the image.

You can also use the docker build command to build an image from a Dockerfile. The docker build command takes a Dockerfile and creates an image from it.

To share an image, you can push it to a public registry such as Docker Hub. Pushing an image to a registry makes it available to anyone who wants to use it.

Docker Hub is a public registry that contains images for many popular applications. You can also create your own private registry.
