1.配置jenkins使用docker

1.1 在jenkins-server主机上配置

#1.验证系统中是否有jenkins用户
[root@jenkins ~]# grep jenkins /etc/passwd
jenkins:x:998:996:Jenkins Automation Server:/var/lib/jenkins:/bin/false

#2.验证系统中是否有docker用户及用户组
[root@jenkins ~]# grep docker /etc/group

#3.创建docker用户组及用户
[root@jenkins ~]# groupadd  docker
[root@jenkins ~]# useradd  docker -g docker
[root@jenkins ~]# grep docker /etc/passwd
docker:x:1000:1000::/home/docker:/bin/bash

#4.添加jenkins用户到docker用户组
[root@jenkins ~]# usermod -G docker jenkins
[root@jenkins ~]# grep docker /etc/group
docker:x:1000:jenkins

#5.重启jenkins服务
[root@jenkin ~]# systemctl restart jenkins

2.密钥配置

2.1 jenkins-server主机至gitlab-ce

#1. 在jenkins-server生成密钥对
[root@jenkins ~]# ssh-keygen

#2.添加公钥至gitlab-ce
[root@jenkins ~]# cat /root/.ssh/id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDDnw76XPLjxogf8OnxbRGOHZta1f9cWI7FxtmhBAMnJT0RpZJNW4jDbXEpvq/IWkt8a/xO2Y67XhIhGituJZXqrJuY34dYNfRap4VFX8wpU6f6xH1nwbCQvLtHOfkERcILUpfS9D8GT7rjLCkN4LE1NxUFAoUnWtq5hU18BjfQhhW/NKu/hpUeG4NKkrvWoLLVhQWGIQIXbKqaKrIYQTmULZ2mKbU8U0A0UKIelJE+U7d8sxEDKonSdI0DZnsy1pZdQnk/3SQAKQLOcxC0UTPApwsPX2oiiI92v5jmZH7iDFEISmiQVfFyCi5xdkradr8vmhbthP22qJZFXCFOwLJN root@jenkins
