kubectl获取pod报拉取错误

我通过如下命令获取nginx

bash 复制代码

[root@master01 docker]# kubectl run nginx1-20-2 --image=nginx:1.20.2 --port=81
pod/nginx1-20-2 created

获取后，查看状态一直是没启动

bash 复制代码

[root@master01 docker]# kubectl get pod
NAME          READY   STATUS              RESTARTS   AGE
nginx1-20-2   0/1     ContainerCreating   0          12s

然后看详细信息

bash 复制代码

kubectl describe pod  nginx1-20-2

报错如下：

大概意思：无法从官网拉取

bash 复制代码

处理方法,配置docker加速器

bash 复制代码

[root@master01 docker]# cd /etc/docker/
[root@master01 docker]# ll
total 8
-rw-r--r--. 1 root root 351 Dec  8 22:44 daemon.json
-rw-------. 1 root root 244 Nov 14 17:20 key.json
#配置加速器如下：
[root@master01 docker]# cat daemon.json 
{
  "registry-mirrors": [
    "https://hub-mirror.c.163.com",
    "https://mirror.baidubce.com",
    "https://registry.docker-cn.com",
    "https://mirror.ccs.tencentyun.com",
    "https://docker.mirrors.ustc.edu.cn",
    "https://hub-mirror.c.163.com",
    "https://docker.1ms.run",
    "https://hub.rat.dev",
    "https://docker.1panel.live"
  ]
}

配置完成后，重启docker
#重新加载 systemd 的配置文件和单元文件
systemctl daemon-reload 
#重启docker
systemctl restart docker
