Introduction to Docker Components

In this part of the course, the key components of Docker are introduced and their roles and interactions are discussed. The Docker Host, running the Docker Daemon, serves as the server part of the Docker Engine Client Server architecture. Docker clients, such as the command line or Docker Desktop, interact with the Docker Daemon. The Docker Host contains containers and container images. Docker images can be obtained by downloading them from a registry or by creating them using a Dockerfile. Containers, which are similar to Docker images but with read-write capabilities, can be run on the Docker Host using the Docker run command. Containers can be stopped, started, and stored in a registry using the Docker push command. This is a high-level overview of the typical Docker deployment architecture, which will be further explored in the course.
