Docker is an open platform for developing, distributing, and running applications as containers. Docker is popular among developers because it is easy, allows for large scalability, and can be utilized across different platforms, environments, and locations. Docker is created in the Go programming language and operates on Linux kernel features. A container is a unit of software that contains everything required to build, ship, and run applications. Containers speed up deployment, cut expenses, increase efficiency, automate tasks, and support modern software like microservices. Applications with monolithic design or those needing high performance or security are not a good fit for Docker containers.

A Dockerfile is used to build new Docker containers. A docker file image is made using a docker file. A running container is made using the image.

The Docker host, the Docker client, and the container registry make up the Docker architecture. Most Docker users interact with Docker primarily through the Docker client. When you use a docker command, the client transmits the command to dockerd, which executes it. The Docker API is utilized by the docker command. items like Dockerfiles, images, containers, networks, storage volumes, and other items like plugins and add-ons are all present in the Docker host. Named container images are stored and distributed via the Container Registry. This concludes this Article
