Docker 添加--insecure-registry 私有鏡像倉庫

方法一

[root@k8s-master01]# vi /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd --insecure-registry 192.168.61.238

[root@k8s-master01]# systemctl  daemon-reload && systemctl restart docker 

方法二

[root@k8s-master01]# cat /etc/docker/daemon.json 

{
  "registry-mirrors": [
    "https://registry.docker-cn.com"
  ]
}
{
  "insecure-registry":["192.168.61.238"]
}

或
[root@k8s-master01]# vi /etc/docker/daemon.json
{
  "registry-mirrors": ["https://0nth4654.mirror.aliyuncs.com"],
  "insecure-registries": ["192.168.61.238"]
}
然后重啟服務
[root@k8s-master01]# systemctl daemon-reload && systemctl restart docker

方法三

適用一些低版本docker

[root@k8s-master01]# vi /usr/lib/systemd/system/docker.service
#修改
ExecStart=/usr/bin/docker daemon -H fd:// --insecure-registry 192.168.1.110:5000
#重啟服務
[root@k8s-master01]# systemctl daemon-reload && systemctl restart docker
