docker images(二):镜像拉取
通过docker命令拉取公共镜像 (docker pull iamges:version)
示例
docker pull redis,通过docker hub 拉取redis lastest版本
docker pull registry.cn-hangzhou.aliyuncs.com/redisl/redis:4.0.12通过阿里云平台拉取redis 4.0.12版本
其中registry.cn-hangzhou.aliyuncs.com/redisl/地址会在搜索到的详情页面出现。具体的版本号，会出现在详情页面下方，加在地址后面即可。
docker pull registry.cn-hangzhou.aliyuncs.com/redisl/redis:4.0.12

docker login --username=${USERNAME} registry.cn-hangzhou.aliyuncs.com
