This article describes some of the basic and most important terms of Docker:
- Image: Mirroring is the cornerstone of building the Docker world, where users create containers based on images, a layered structure based on a federated file system, built by a series of instructions. It is easy to understand that mirroring is the program code that a container runs.
- Registry: Docker uses Registry to save user-built images. Registry is divided into public and private two kinds. The public registry that Docker operates is called the Docker Hub. Users can register their account on the Docker hub to share and save the images they have built.
- Containers (Container): Containers are initiated based on mirroring and can run one or more processes in a container, and we can assume that mirroring is the build and package phase in the Docker lifecycle, and the container is the start and execute phase.
