描述
将一个或多个图像保存到 tar 归档文件（默认流式传输到 STDOUT）
使用
docker save [OPTIONS] IMAGE [IMAGE...]
备选方案
Name, shorthand | Default | Description |
|---|---|---|
--output, -o | Write to a file, instead of STDOUT |
父命令
Command | Description |
|---|---|
docker | The base command for the Docker CLI. |
扩展描述
生成标准输出流的存储库。包含所有父层和所有标记+版本，或指定repo:tag，对于所提供的每一个论点。
实例
创建一个备份，然后可以与docker load...
$ docker save busybox > busybox.tar $ ls -sh busybox.tar2.7M busybox.tar $ docker save --output busybox.tar busybox $ ls -sh busybox.tar2.7M busybox.tar $ docker save -o fedora-all.tar fedora $ docker save -o fedora-latest.tar fedora:latest
Cherry-pick 特定的标签
您甚至可以选择图像存储库的特定标记。
$ docker save -o ubuntu.tar ubuntu:lucid ubuntu:saucy
