一、搜索镜像

很多情况下我们可能需要下载某一类别的镜像，这时候我们就会用到搜索功能，也可以去 docker hub 官网页面搜索。
使用语法如下。

Usage:  docker search [OPTIONS] TERM

Search the Docker Hub for images

Options:
  -f, --filter filter   Filter output based on conditions provided
      --format string   Pretty-print search using a Go template
      --help            Print usage
      --limit int       Max number of search results (default 25)
      --no-trunc        Don't truncate output

我们可以看到，第一个镜像是没有用户名的，并且 OFFICIAL 是 OK，这样的镜像是由 Docker 公司进行维护的。

二、下载镜像

使用方法如下。

Usage:  docker pull [OPTIONS] NAME[:TAG|@DIGEST]

Pull an image or a repository from a registry

Options:
  -a, --all-tags                Download all tagged images in the repository
      --disable-content-trust   Skip image verification (default true)
      --help                    Print usage

正常情况下，我们输入查到的镜像的全称即可。

三、查看本地镜像

Usage:  docker images [OPTIONS] [REPOSITORY[:TAG]]

List images

Options:
  -a, --all             Show all images (default hides intermediate images)
      --digests         Show digests
  -f, --filter filter   Filter output based on conditions provided
      --format string   Pretty-print images using a Go template
      --help            Print usage
      --no-trunc        Don't truncate output
  -q, --quiet           Only show numeric IDs

四、显示镜像构建历史

Usage:  docker history [OPTIONS] IMAGE

Show the history of an image

Options:
      --format string   Pretty-print images using a Go template
      --help            Print usage
  -H, --human           Print sizes and dates in human readable format (default true)
      --no-trunc        Don't truncate output
  -q, --quiet           Only show numeric IDs

五、删除镜像

Usage:  docker rmi [OPTIONS] IMAGE [IMAGE...]

Remove one or more images

Options:
  -f, --force      Force removal of the image
      --help       Print usage
      --no-prune   Do not delete untagged parents

六、镜像创建

Usage:  docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]

Create a new image from a container's changes

Options:
  -a, --author string    Author (e.g., "John Hannibal Smith <hannibal@a-team.com>")
  -c, --change list      Apply Dockerfile instruction to the created image
      --help             Print usage
  -m, --message string   Commit message
  -p, --pause            Pause container during commit (default true)

之前我们已经演示过了。

七、上传镜像

Usage:  docker push [OPTIONS] NAME[:TAG]

Push an image or a repository to a registry

Options:
      --disable-content-trust   Skip image signing (default true)
      --help                    Print usage

之前已经演示过。

八、给镜像打 tag

Usage:  docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]

Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE

Options:
      --help   Print usage

之前已经演示过。

九、存出和载入镜像

Usage:  docker save [OPTIONS] IMAGE [IMAGE...]

Save one or more images to a tar archive (streamed to STDOUT by default)

Options:
      --help            Print usage
  -o, --output string   Write to a file, instead of STDOUT

Usage:  docker load [OPTIONS]

Load an image from a tar archive or STDIN

Options:
      --help           Print usage
  -i, --input string   Read from tar archive file, instead of STDIN

-q, --quiet Suppress the load output
