container-diff 谷歌开源镜像分析工具使用
2024-09-04 12:44:12
1. 安装
curl -LO https://storage.googleapis.com/container-diff/latest/container-diff-linux-amd64 && chmod +x container-diff-linux-amd64 && sudo mv container-diff-linux-amd64 /usr/local/bin/container-diff
备注：
安装的时候是在阿里云的机器，但是就是网络不通，最简单的方法是先下载在上传阿里云服务器
storage.googleapis.com国内 还是可以使用的2. 命令
a.全部
sage:
container-diff [command]
Available Commands:
analyze Analyzes an image: [image]
diff Compare two images: [image1] [image2]
help Help about any command
version Print the version of container-diff
Flags:
-h, --help help for container-diff
-v, --verbosity string This flag controls the verbosity of container-diff. (default "warning")
b. analyze
Usage:
container-diff analyze [flags]
Flags:
-h, --help help for analyze
-j, --json JSON Output defines if the diff should be returned in a human readable format (false) or a JSON (true).
-n, --no-cache Set this to force retrieval of layers on each run.
-o, --order Set this flag to sort any file/package results by descending size. Otherwise, they will be sorted by name.
-s, --save Set this flag to save rather than remove the final image filesystems on exit.
-t, --type Diff Types This flag sets the list of analyzer types to use. Set it repeatedly to use multiple analyzers.
Global Flags:
-v, --verbosity string This flag controls the verbosity of container-diff. (default "warning")
c. 2. 分析镜像
a. 参考命令
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]
本地镜像：daemon://
container-diff analyze daemon://dalongrong/fn:0.0.3
远程镜像：remote://
container-diff analyze nginx
输出如下：

1. 参考命令：
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]
2. 使用（和上面的一样daemon:// 本地镜像 remote:// 远程 ）
container-diff remote://docker.io/dalongrong/fn:0.0.9 remote://docker.io/dalongrong/mqttmosca
具体信息就不粘贴了，太多了4. 附加参数
比如： -j or --json 生成json 格式的数据5. 总结
功能很强很大，容器的黑匣子对于我们来说就比较清晰了。5. 参考资料
