# Docker 运行
docker pull wagoodman/dive

或者
docker pull quay.io/wagoodman/dive

# 使用该镜像运行一个临时的容器，加上我们需要分析的镜像
docker run --rm -it \
    -v /var/run/docker.sock:/var/run/docker.sock \
    wagoodman/dive:latest <dive arguments...>

dive 命令补充说明：

dive

按层显示 Docker 镜像内容：在左侧选择一个图层时，将显示该图层的内容以及右侧的所有先前图层。此外，您还可以使用箭头键全面浏览文件树。

指出每一层的变化：文件树中指示已更改，修改，添加或删除的文件。可以对其进行调整以显示特定层的更改，或显示直到该层的汇总更改估计。

图像效率：左下方的窗格显示基本图层信息和实验指标，该指标将猜测图像所包含的浪费空间。这可能是由于跨层复制文件，跨层移动文件或没有完全删除文件。提供百分比 得分 和 总浪费文件空间。

快速的构建 / 分析周期：您可以构建一个 Docker 镜像并使用以下命令立即进行分析：dive build -t some-tag。您只需要用 docker build 相同的 dive build 命令替换命令即可。

dive 命令语法：

# Analyze a Docker image
dive [your_image_tag]

# Build an image and start analyzing it
dive build -t [some_tag]

dive [IMAGE] [flags] 
dive [command]

dive 命令选项：

Available Commands:
  build       Builds and analyzes a docker image from a Dockerfile (this is a thin wrapper for the `docker build` command). 
  help        Help about any command 
  version     print the version number and exit (also --version) 

Flags:
      --ci                                Skip the interactive TUI and validate against CI rules (same as env var CI=true) 
      --ci-config string                  If CI=true in the environment, use the given yaml to drive validation rules. (default ".dive-ci") 
      --config string                     config file (default is $HOME/.dive.yaml, ~/.config/dive/*.yaml, or $XDG_CONFIG_HOME/dive.yaml) 
  
  -h, --help                              help for dive 
      --highestUserWastedPercent string   (only valid with --ci given) highest allowable percentage of bytes wasted (as a ratio between 0-1), otherwise CI validation will fail. (default "0.1") 
      --highestWastedBytes string         (only valid with --ci given) highest allowable bytes wasted, otherwise CI validation will fail. (default "disabled") 
  
  -i, --ignore-errors                     ignore image parsing errors and run the analysis anyway 
  
  -j, --json string                       Skip the interactive TUI and write the layer analysis statistics to a given file. 
      --lowestEfficiency string           (only valid with --ci given) lowest allowable image efficiency (as a ratio between 0-1), otherwise CI validation will fail. (default "0.9") 
      --source string                     The container engine to fetch the image from. Allowed values: docker, podman, docker-archive (default "docker") 
  
  -v, --version                           display version number

or

dive <source>://<your-image>
source 选项支持：

docker：Docker引擎（默认选项）
docker-archive：来自磁盘的 Docker Tar 存档
podman：Podman引擎（仅Linux）
