2.jenkins环境搭建与启动

jenkins的环境搭建步骤:
1.搜索jenkins：docker search jenkins
2.拉取jenkins镜像：docker pull jenkins/jenkins:lts
3.查看jenkins镜像：docker images
4.创建本地数据卷:
mkdir -p /var/jenkins_home/ #创建目录
chmod 777 /var/jenkins_home/ #修改权限目录
5.创建容器:docker run -id --name=jenkins -p 7070:8080 -v /var/jenkins_home/:/var/jenkins_home jenkins/jenkins:lts
其中命令详解：注意冒号后面的全部是固定值，不能改变，前面可以变更。
-d:容器后台运行
-p:端口映射
-v:数据卷挂载，绑定数据库
6.配置jenkins，访问网址：http://宿主机ip:7070/
7.界面进入jenkins,输入管理员密码：cat /var/jenkins_home/secrets/initialAdminPassword #获取管理员密码

提升技巧
1.容器的配置文件修改对应的端口号---修改完请重启容器
/var/lib/docker/containers/容器的id/hostconfig.json
docker start 容器id
2.docker logs 容器id #指令获取jenkins密码
jenkins密码获取执行命令-方式一：
docker logs 132e5cf78f6a
或者
2.cat /var/jenkins_node/secrets/initialAdminPassword#该指令也可以获取jenkins密码
jenkins密码获取执行命令-方式二：
[root@ecs-429b ~]$>cat /var/jenkins_home/secrets/initialAdminPassword
a778cdbb6b81448b963c3eb81ef183b9

3.jenkins下安装python相关资源

4.jenkins相关资源文档
