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。

Usage:  docker search [OPTIONS] TERMSearch the Docker Hub for imagesOptions:  -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 registryOptions:  -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 imagesOptions:  -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] IMAGEShow the history of an imageOptions:      --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 imagesOptions:  -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 changesOptions:  -a, --author string    Author (e.g., "John Hannibal Smith 
    
     ")  -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 registryOptions:      --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_IMAGEOptions:      --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 STDINOptions:      --help           Print usage  -i, --input string   Read from tar archive file, instead of STDIN  -q, --quiet          Suppress the load output
