- Dockerfile: It consists of instructions on how to build an image that runs our program.
- Docker client: This is a command-line program used by the user to interact with Docker daemon.
- Docker daemon: This is the Daemon application that listens for commands to manage building or running containers and pushing containers to Docker registry. It is also responsible for configuring container networks, volumes, and so on.
- Docker images: Docker images ...
