镜像提交harbor
构建提示如下异常：
docker login 192.168.191.101 -u admin -p Harbor12345 WARNING! Using --password via the CLI is insecure. Use --password-stdin. Error response from daemon: Get "https://192.168.191.101/v2/": dial tcp 192.168.191.101:443: connect: connection refused
结局docker client默认使用https,测试环境使用http，修改docker配置文件
修改/etc/docker/daemon.json文件，添加如下
"insecure-registries" : ["http://192.168.191.101:80", "0.0.0.0"]
http要写，不然还是默认走https
依赖包安装
sudo yum install -ycurl policycoreutils-python openssh-server perl sudo systemctl enable sshd sudo systemctl start sshd sudo firewall-cmd --permanent--add-service=http sudo firewall-cmd --permanent--add-service=https sudo systemctl reload firewalld sudo yum install postfix sudo systemctl enable postfix sudo systemctl start postfix curl-fsSL https://packages.gitlab.cn/repository/raw/scripts/setup.sh | /bin/bash
配置域名及安装：
sudo EXTERNAL_URL="http://192.168.191.102" yum install -y gitlab-jh
参考命令：
重新配置极狐GitLab：
sudo gitlab-ctl reconfigure
获取root密码cat /etc/gitlab/initial_root_password
访问gitlab.
提交代码到gitlab，通过webhook自动触发jenkins构建工程，并推送到harbor镜像仓库
