常用示例
Show filesystem changes in a container
docker diff [container_name]
Show changes using container ID
docker diff [container_id]
说明
docker diff inspects changes to files or directories on a container's filesystem since the container was created from its base image. The output categorizes each change with a single-character prefix: A for added, C for changed/modified, and D for deleted. This command is useful for understanding what modifications have occurred within a running or stopped container, which helps in debugging, auditing changes, or determining what should be captured in a new image via docker commit. Only changes in the container's writable layer are reported; the underlying image layers remain unchanged. You can reference the container by name or by full/shortened container ID.
