K8S/Kubernetes

做微服务的时候，我准备把编译好的jar包，部署到我的Harbor仓库上，却登录不上去，出现以下报错：

[root@k8s-master ~]# docker login 192.168.30.24
Username: admin   
Password:
Error response from daemon: Get https://192.168.30.24/v2/: dial tcp 192.168.30.24:443: connect: connection refused
这里说拒绝连接，因为我是用http部署的harbor，这里是https://进行访问的，所有出现报错

然后解决这个问题其实就在/etc/docker/daemon.json文件下

添加对私有仓库的认证就可以登录了

[root@k8s-master ~]# vim /etc/docker/daemon.json

{
        "registry-mirrors": ["http://f1361db2.m.daocloud.io"],
        "insecure-registries": ["192.168.30.24"]
}

重启docker
[root@k8s-master ~]# systemctl restart docker

登录，这里说你已经登陆了，在另一台主机。OK，问题解决
[root@k8s-master ~]# docker login 192.168.30.24
Username: admin
