1.获取下载制定版本的镜像的办法：

https://hub.docker.com/

去这个地方搜索，然后可以看到这样的内容
在这里插入图片描述

2.第二种办法，通过安装插件可以获取所有镜像列表信息
示例中以centos为例，如果查询别的，把下面的centos换成你需要的内容就是可以了

curl -s https://registry.hub.docker.com/v1/repositories/centos/tags|jq|grep name

2.1使用前需要安装一个插件（jq）

yum install jq

2.2centos镜像示例

[root@centos77 ~]# curl -s https://registry.hub.docker.com/v1/repositories/centos/tags|jq|grep name
    "name": "latest"
    "name": "5"
    "name": "5.11"
    "name": "6"
    "name": "6.10"
    "name": "6.6"
    "name": "6.7"
    "name": "6.8"
    "name": "6.9"
    "name": "7"
    "name": "7.0.1406"
    "name": "7.1.1503"
    "name": "7.2.1511"
    "name": "7.3.1611"
    "name": "7.4.1708"
    "name": "7.5.1804"
    "name": "7.6.1810"

2.3nginx镜像示例

[root@centos77 ~]# curl -s https://registry.hub.docker.com/v1/repositories/nginx/tags|jq|grep name
    "name": "latest"
    "name": "1"
    "name": "1-alpine"
    "name": "1-alpine-perl"
    "name": "1-perl"
    "name": "1.10"
    "name": "1.10-alpine"
    "name": "1.10.0"
    "name": "1.10.0-alpine"
    "name": "1.10.1"
    "name": "1.10.1-alpine"
    "name": "1.10.2"
    "name": "1.10.2-alpine"
    "name": "1.10.3"
    "name": "1.10.3-alpine"
    "name": "1.11"
    "name": "1.11-alpine"
    "name": "1.11.0"
    "name": "1.11.0-alpine"

2.4获取到镜像列表信息后就是可以下载列表中的内容了

示例:
以下载nginx的1.11为例进行下载的方式


[root@centos77 ~]# docker pull nginx:1.11

2.5查看下载镜像的方法：


[root@centos77 ~]# docker images
