三、jenkins安装

docker/k8s方式安装jenkins

docker方式部署

镜像：

1
2
3
4
# 官方
docker pull jenkins/jenkins:lts
# 自有阿里云docker仓库
docker pull registry.cn-hangzhou.aliyuncs.com/zznn/jenkins:lts

构建jenkins

如果jenkins无法启动则是持久化宿主机目录权限有问题 **chown -R 1000 /mydata/jenkins_home

1
2
mkdir -p /mydata/jenkins_home
docker run -di --name=jenkins -p 8080:8080 -v /mydata/jenkins_home:/var/jenkins_home registry.cn-hangzhou.aliyuncs.com/zznn/jenkins:lts

docker-compose

初始化完成后本教程创建admin账户默认密码等都写admin

映射目录

安装完成（最后初始化过程需要点击使用admin账户继续）
