openshift提供paas平台
- Install and configure the necessary dependencies
sudo yum install curl policycoreutils openssh-server openssh-clients sudo systemctl enable sshd sudo systemctl start sshd sudo yum install postfix sudo systemctl enable postfix sudo systemctl start postfix sudo firewall-cmd --permanent --add-service=http sudo systemctl reload firewalld- Add the GitLab package server and install the package
curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash sudo yum install gitlab-ce- Configure and start GitLab
sudo gitlab-ctl reconfigure- 安装jenkins源
sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins.io/redhat-stable/jenkins.repo sudo rpm --import http://pkg.jenkins.io/redhat-stable/jenkins.io.key- 执行安装命令
yum install jenkinspass
yum install docker修改jenkins slave机器下/etc/sysconfig/docker为如下： 目的：调用docker remote api

- 安装openshift-server，openshift-clinet，docker-registry
- 在openshift-client端执行创建模板文件rdc.json,内容如下
