问题：

docker pull harbor.core.powercloud.com/public/prom/prometheus@sha256:8b93af55f1e8b1bc3e95d11292a72a90ea6aa85efe680c5adb09d9545f637f8f
Trying to pull repository harbor.core.powercloud.com/public/prom/prometheus ...
Get https://harbor.core.powercloud.com/v2/: x509: certificate signed by unknown authority

解决办法:

1. 配置docker服务的配置文件

可用find / -name docker.service搜索服务地址

vi /usr/lib/systemd/system/docker.service

在配置文件中添加如下一段：（注意这里的：harbor.core.powercloud.com 是docker私库的地址）

--insecure-registry=harbor.core.powercloud.com \?

2. 重新加载服务配置文件

????????systemctl daemon-reload

3. 登录私库

????????docker login https://harbor.core.powercloud.com/v2/

4. 即可成功拉取镜像????????????????
