Docker自建私有仓库遇到https问题

记录一下自己在自建Docker仓库的时候遇到的一个报错

• 问题

docker push registry:5000/library/centos:7
The push refers to repository [registry:5000/library/centos]
Get "https://registry:5000/v2/": http: server gave HTTP response to HTTPS client

• 解决办法

vim /etc/docker/daemon.json
{
    ...
    # 这里后面一定要写两个哈，我这里就写成一样的了
    "insecure-registries": ["registry:5000","registry:5000"]
}

systemctl restart docker
docker push registry:5000/library/centos:7
# success

• 个人猜测：insecure-registries这个后面的列表中第一个使用的是https，第二个是使用的http。
