dockerpool CA 证书错误

docker被墙后用，拉dockerpool的镜像会出现这个错误 > sudo docker pull dl.dockerpool.com:5000/centos:7 FATA[0000] Error response from daemon: v1 ping attempt failed with error: Get https://dl.dockerpool.com:5000/v1/_ping: tls: oversized record received with length 28012. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry dl.dockerpool.com:5000` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/dl.dockerpool.com:5000/ca.crt 解决方法，在/etc/sysconfig/docker添加 INSECURE_REGISTRY='--insecure-registry dl.dockerpool.com:5000' 版本如下
