Centos7配置Docker镜像加速器(报错Error response from daemon: pull access denied for centos7, repository does )

我们在日常学习或者使用docker的时候可能会遇到下载安装镜像速度慢的问题,这里我们就得添加以下中国的阿里云镜像就会速度加快。

但是在添加阿里云镜像后会出现身份验证的报错信息：

Error response from daemon: pull access denied for centos7, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

第一步：添加阿里云镜像

在阿里云主页搜索：镜像  或  容器镜像服务即可

https://www.aliyun.com/

 第二步：进入容器镜像服务控制台

点击镜像工具 

 第三步：按照官网文档复制粘贴即可

选择自己的Linux版本

 按照命令粘贴执行即可

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://wgqumcjo.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

第四步：拉取镜像报错

[root@centos7 ~]# docker pull centos7
Using default tag: latest
Error response from daemon: pull access denied for centos7, repository does not exist or may require 'docker login': denied: requested access to the resource is denied

第五步：报错解决

出现此问题的原因为未进行身份识别

①点击实例列表进行创建

 ②点击访问凭证

③将代码复制到自己的终端中执行

[root@centos7 ~]# docker login --username=15754855859 registry.cn-hangzhou.aliyuncs.com
Password:

Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

 password：输入自己的阿里云密码

第六步：搜索镜像进行拉取即可

[root@centos7 ~]# docker search centos7
