Docker container images

Docker container images are the fundamental packaging units used to create and run containers.^[400-devops__06-Kubernetes__k8s-paas__原理及源码解析__README.md]

Overview

In the context of Docker and containerization, an image serves as a read-only template that contains a set of instructions for creating a container that can run on the Docker platform.^[400-devops__06-Kubernetes__k8s-paas__原理及源码解析__README.md]

Key Concepts

  • Deep Understanding: A thorough grasp of container images involves understanding their layered architecture and how they function as a snapshot of a filesystem.^[400-devops__06-Kubernetes__k8s-paas__原理及源码解析__README.md]
  • Comparison: Understanding the distinction between container images and virtual machine images is critical for grasping the efficiency of the container model.^[400-devops__06-Kubernetes__k8s-paas__原理及源码解析__README.md]
  • Isolation: Images work in conjunction with kernel features to ensure that the running container is isolated from the host and other containers.^[400-devops__06-Kubernetes__k8s-paas__原理及源码解析__README.md]
