以下是配置文件docker-compose：

data:
 build: jenkins-data
master:
 build: jenkins-master
 volumes_from:
  - data
 ports:
 - "50000:50000"
nginx:
 build: jenkins-nginx
 ports:
  - "80:80"
  - "443:443"
 links:
  - master:jenkins-master
# volumes:
#  - /etc/letsencrypt:/etc/letsencrypt
slave:
 build: jenkins-slave
#slavedotnet:
# build: jenkins-dotnetcore-slave

在这里可用。

运行以下命令后：

docker-compose -f jenkinsDocker/docker-compose.yml -p jenkins up -d nginx data master

从浏览器启动时，詹金斯大师显示以下错误：
