Explanation
A container image is a static, immutable package that contains an application along with all its required dependencies, libraries, and configuration files. Containerization documentation defines a container image as a snapshot of an application and its runtime environment, which can be instantiated as a running container. Container images do not include a full operating system kernel; instead, containers share the host system's kernel. This design makes containers lightweight and fast to deploy compared to traditional virtual machines.
