  from your infrastructure so
  you can deliver software quickly. With Docker, you can manage your infrastructure
  in the same ways you manage your applications. By taking advantage of Docker's
  methodologies for shipping, testing, and deploying code, you can
  significantly reduce the delay between writing code and running it in production.The Docker platformDocker provides the ability to package and run an application in a loosely isolated
  environment called a container. The isolation and security lets you run many
  containers simultaneously on a given host. Containers are lightweight and contain
  everything needed to run the application, so you don't need to rely on what's
  installed on the host. You can share containers while you work,
  and be sure that everyone you share with gets the same container that works in the
  same way.Docker provides tooling and a platform to manage the lifecycle of your containers:Develop your application and its supporting components using containers.The container becomes the unit for distributing and testing your application.When you're ready, deploy your application into your production environment,
  as a container or an orchestrated service. This works the same whether your
  production environment is a local data center, a cloud provider, or a hybrid
  of the two.What can I use Docker for?Fast, consistent delivery of your applicationsDocker streamlines the development lifecycle by allowing developers to work in
  standardized environments using local containers which provide your applications
  and services. Containers are great for continuous integration and continuous
  delivery (CI/CD) workflows.Consider the following example scenario:Your developers write code locally and share their work with their colleagues
  using Docker containers.They use Docker to push their applications into a test environment and run
  automated and manual tests.When developers find bugs, they can fix them in the development environment
  and redeploy them to the test environment for testing and validation.When testing is complete, getting the fix to the customer is as simple as
  pushing the updated image to the production environment.Responsive deployment and scalingDocker's container-based platform allows for highly portable workloads. Docker
  containers can run on a developer's local laptop, on physical or virtual
  machines in a data center, on cloud providers, or in a mixture of environments.Docker's portability and lightweight nature also make it easy to dynamically
  manage workloads, scaling up or tearing down applications and services as
  business needs dictate, in near real time.Running more workloads on the same hardwareDocker is lightweight and fast. It provides a viable, cost-effective alternative
  to hypervisor-based virtual machines, so you can use more of your server
  capacity to achieve your business goals. Docker is perfect for high density
  environments and for small and medium deployments where you need to do more with
  fewer resources.Docker architectureDocker uses a client-server architecture. The Docker client talks to the
  Docker daemon, which does the heavy lifting of building, running, and
  distributing your Docker containers. The Docker client and daemon can
  run on the same system, or you can connect a Docker client to a remote Docker
  daemon. The Docker client and daemon communicate using a REST API, over UNIX
  sockets or a network interface. Another Docker client is Docker Compose,
  that lets you work with applications consisting of a set of containers.
  The Docker daemonThe Docker daemon (dockerd) listens for Docker API requests and manages Docker
  objects such as images, containers, networks, and volumes. A daemon can also
  communicate with other daemons to manage Docker services.The Docker clientThe Docker client (docker) is the primary way that many Docker users interact
  with Docker. When you use commands such as docker run, the client sends these
  commands to dockerd, which carries them out. The docker command uses the
  Docker API. The Docker client can communicate with more than one daemon.Docker DesktopDocker Desktop is an easy-to-install application for your Mac, Windows or Linux environment that enables you to build and share containerized applications and microservices. Docker Desktop includes the Docker daemon (dockerd), the Docker client (docker), Docker Compose, Docker Content Trust, Kubernetes, and Credential Helper. For more information, see
  Docker Desktop.Docker registriesA Docker registry stores Docker images. Docker Hub is a public
  registry that anyone can use, and Docker looks for images on
  Docker Hub by default. You can even run your own private registry.When you use the docker pull or docker run commands, Docker pulls the required images
