How Docker Interacts With Containerd
Docker interacts with contained primarily through its architecture and components:
- Integration as Core Runtime: Docker uses contained as its main container runtime for handling essential container operations such as container creation, execution and management on behalf of Docker.
- API Communication: Docker communicates with contained with the help of API calls. Docker Engine interacts with Containerd’s API to perform container-related tasks, such as pulling, container images, creating containers and managing container lifecycle.
- Containerd Daemon: Containerd operates as a standalone daemon that listens the commands from Docker and perform container related operations. Docker CLI sends the request to Containerd daemon and its execute those operations on Docker’s behalf.
- Image Management: Docker manages the container images using its higher level features like Docker CLI and Docker Registry. When it need to perform operations such as pull, push or manage container images it communicates with containerd to perform image related tasks.
