Error response from daemon: Get “*“: x509: certificate signed by unknown authority

环境说明

我搭建的harbor仓库，是需要用域名和https方式访问

报错一，其他docker环境登陆harbor时

[root@k8s0001 ~]# docker login www.harbor.wuhan.cn
Username: admin
Password: 
Error response from daemon: Get "https://www.harbor.wuhan.cn/v2/": x509: certificate signed by unknown authority

报错二，其他docker环境拉取自建harbor仓库镜像时

[root@k8s0001 ~]# docker pull www.harbor.wuhan.cn/22202/helloworld@sha256:0d9ce49958ea82a48c40a397ccc785674ec3ce1dfd4f749c3c7c7a63790a54cd
Error response from daemon: Get "https://www.harbor.wuhan.cn/v2/": x509: certificate signed by unknown authority

这两个报错的需要把生成的密钥cp到对应机器docker的配置文件目录即可，操作如下：

配置https链接

然后重启上述docker即可

[root@k8s0001 opt]# systemctl restart docker
[root@k8s0002 opt]# systemctl restart docker
[root@k8s0003 opt]# systemctl restart docker
