Quickstart
单个分析：
container-diff analyze <img> [Run default analyzers] container-diff analyze <img> --type=history [History] container-diff analyze <img> --type=file [File System] container-diff analyze <img> --type=pip [Pip] container-diff analyze <img> --type=apt [Apt] container-diff analyze <img> --type=node [Node] container-diff analyze <img> --type=apt --type=node [Apt and Node] # --type=<analyzer1> --type=<analyzer2> --type=<analyzer3>,...
多个对比：
container-diff diff <img1> <img2> [Run default differs] container-diff diff <img1> <img2> --type=history [History] container-diff diff <img1> <img2> --type=file [File System] container-diff diff <img1> <img2> --type=pip [Pip] container-diff diff <img1> <img2> --type=apt [Apt] container-diff diff <img1> <img2> --type=node [Node]
