配置docker信任私有镜像仓库​

如果你的私有镜像仓库未配置https或者自签发https证书需要配置docker信任.

    1. 未配置https或者自签发证书(不被浏览器信任的),则需要配置dockerinsecure-registries值,需要完需要重启docker
"insecure-registries": ["goodrain.me","hub.test.com"],
    1. 自签发证书，且docker不需要重启

需要将自签发域名的证书拷贝到如下路径 /etc/docker/certs.d/<私有镜像仓库域名>/

示例goodrain.me

root@compute-node-99:/etc/docker/certs.d/goodrain.me# ls
server.crt
