did not detect an --insecure-registry argument on the Docker daemon解决方法

问题描述：

启动Openshift（openshift-origin-server-v3.11.0-0cbc58b-linux-64bit）时，报错信息如下所示：

[root@zeppelin openshift]# oc cluster up
Getting a Docker client ...
Checking if image openshift/origin-control-plane:v3.11 is available ...
Checking type of volume mount ...
Determining server IP ...
Checking if OpenShift is already running ...
Checking for supported Docker version (=>1.22) ...
Checking if insecured registry is configured properly in Docker ...
error: did not detect an --insecure-registry argument on the Docker daemon

解决方法：

如下，在启动命令中跳过相关检查

oc cluster up --skip-registry-check=true

参考：https://github.com/openshift/origin/issues/8997

其它说明

照网上的各种办法（主要在docker不同位置的配置文件中添加相关内容），最后虽然docker info命令已经可以查询到添加的仓库信息，但是依然不好使：
