  What is Docker? Docker is an open-source containerization platform for developing, shipping, and running applications.  "It helps developers put their apps into containers."  Containers allow for consistent environments across different stages of development.

  Key components ofDocker  Docker Engine: It is a core part of docker, that handles the creation and management of containers. 1.Server 2. Rest Api 3. Client  Docker Image: it is a read-only template that is used for creating containers, containing the application code and dependencies.  Docker Hub: It is a cloud based repository that is used for finding and sharing the container images.  Docker file: It is a script that containing instruction to build a docker image.  Docker registry: It is a storage distribution system for docker images, where we can store the images in both public and private models.

  How Docker Works Docker uses Images, which are lightweight, standalone, and executable software packages.  Containers are instances of images that run isolated processes.
• 8.
  Docker Architecture  DockerEngine: Core part of Docker engine, composed of Docker Daemon and CLI.  Docker Daemon: Manages Docker objects like images, containers, and networks.  Docker CLI: Command-line interface to interact with Docker.  Docker Registry: All the docker images are stored in the docker registry. There is a public registry known as a Hub. That can be used by anyone. We can run our private registry also.

  Docker use cases?
• 10.
  Popular Docker Commands •dockerbuild: Create an image from a Dockerfile. •docker run: Start a container from an image. •docker ps: List running containers. •docker stop: Stop a running container.

  Advantages of Docker Docker uses less memory.  Containers run faster than the other Virtual Machines.  It is lightweight.  It allows us to use a remote repository to share your containers with other teams.  To reduce the risks, it uses dependencies.
• 12.
  Disadvantage of Docker Complexity will increase due to layering.  It is difficult to manage a large number of containers.  For an application that needs better graphics, Docker is not suitable for it. (limited access of gpu support)
