使用的镜像加速/etc/docker/daemon.json文件格式不规范导致docker服务启动报错

错误原因：

使用镜像加速，配置了/etc/docker/daemon.json文件，在配置该文件时没有符合json格式规范。

解决方法：

检查该json文件确保符合json格式规范，然后执行systemctl daemon-reload后,启动docker服务。

docker push镜像到私有仓库时报错

错误原因：

可能是由于客户端采用https，docker registry未采用https服务所致

错误现象：

The push refers to repository [192.168.163.132:5000/ubuntu]
Get https://192.168.163.132:5000/v2/: http: server gave HTTP response to HTTPS client

解决方法：

在/etc/docker/daemon.json中添加私有仓库的IP，然后执行systemctl daemon-reload后,启动docker服务。
