docker常见的镜像命令

大家好，今天给大家介绍一下docker镜像的常见命令

查看docker版本

[root@localhost ~] Client: Docker Engine - Community Version: 20.10.12 API version: 1.41 Go version: go1.16.12 Git commit: e91ed57 Built: Mon Dec 13 11:45:41 2021 OS/Arch: linux/amd64 Context: default Experimental: true Server: Docker Engine - Community Engine: Version: 20.10.12 API version: 1.41 (minimum version 1.12) Go version: go1.16.12 Git commit: 459d0df Built: Mon Dec 13 11:44:05 2021 OS/Arch: linux/amd64 Experimental: false containerd: Version: 1.4.12 GitCommit: 7b11cfaabd73bb80907dd23182b9347b4245eb5d runc: Version: 1.0.2 GitCommit: v1.0.2-0-g52b36a2 docker-init: Version: 0.19.0 GitCommit: de40ad0

也可以看docker官网上提供的帮助

它的地址：docker的在线帮助点这里

查看docker镜像

[root@localhost ~] REPOSITORY TAG IMAGE ID CREATED SIZE hello-world latest feb5d9fea6a5 5 months ago 13.3kB [root@localhost ~] 

它的具体解释：

REPOSITORY ：镜像的仓库源 TAG ： 这是镜像的标签 IMAGE ID ： 这是镜像的id CREATED 镜像的创建时间 SIZE 镜像的大小 

有关这条命令的帮助

[root@localhost ~] 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 --no-trunc Don't truncate output -q, --quiet Only show image IDs [root@localhost ~] 

这里注意两个： -a : 列出所有镜像(默认的) -q :只显示镜像的id 

实操：

搜索镜像：

拉取镜像

[root@localhost ~] Using default tag: latest latest: Pulling from library/mysql 72a69066d2fe: Pull complete 93619dbc5b36: Pull complete  99da31dd6142: Pull complete 626033c43d70: Pull complete 37d5d7efb64e: Pull complete ac563158d721: Pull complete d2ba16033dad: Pull complete 688ba7d5c01a: Pull complete 00e060b6d11d: Pull complete 1c04857f594f: Pull complete 4d7cfa90e6ea: Pull complete e0431212d27d: Pull complete Digest: sha256:e9027fe4d91c0153429607251656806cc784e914937271037f7738bd5b8e7709  Status: Downloaded newer image for mysql:latest //这一行表示它的最新的镜像 docker.io/library/mysql:latest //这是它的真实地址 

这条命令拉取的镜像，

默认使用最新的，也可以添加标签，使用指定的版本

docker pull mysql
和
docker pull docker.io/library/mysql:latest //这两条命令是等价的

可以指定它的版本：

[root@localhost ~] 5.7: Pulling from library/mysql 72a69066d2fe: Already exists 93619dbc5b36: Already exists 99da31dd6142: Already exists 626033c43d70: Already exists 37d5d7efb64e: Already exists ac563158d721: Already exists d2ba16033dad: Already exists 0ceb82207cd7: Pull complete 37f2405cae96: Pull complete e2482e017e53: Pull complete 70deed891d42: Pull complete Digest: sha256:f2ad209efe9c67104167fc609cca6973c8422939491c9345270175a300419f94 Status: Downloaded newer image for mysql:5.7 docker.io/library/mysql:5.7 [root@localhost ~]

删除指定id 的容器：

 docker rmi -f $(docker images -q) //删除所有的镜像 docker rmi -f 镜像id 镜像id 镜像 id //同时删除多个镜像
