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]
