在Docker上搭建Jenkins环境

Posted on Edited on In
  1. 从网易镜像仓库下载Jenkins

网易镜像仓库

拉取到本地

1
docker pull hub.c.163.com/library/jenkins:latest

查看镜像

1
docker images

REPOSITORY                      TAG                 IMAGE ID            CREATED             SIZE
hub.c.163.com/library/jenkins   latest              88d9d8a30b47        8 months ago        810MB

从官网下载最新的Jenkins

1
wget http://updates.jenkins-ci.org/download/war/2.107.2/jenkins.war

DockerFile

3
FROM hub.c.163.com/library/jenkins
# 将最新的Jenkins拷贝到`/usr/share/jenkins/`目录
ADD jenkins.war /usr/share/jenkins/

常见镜像

1
docker build -t avery/jenkins .

启动一个Container

1
docker run --name prod_jenkins2 -d -p 9005:8080 -p 9006:50000 -v  /Users/avery/docker/jenkins/backup/jenkins_home:/var/jenkins_home avery/jenkins
  1. 创建本地Jenkins数据目录，将该目录映射到docker中的Jenkins目录，方便备份数据
  2. 8080端口是Jenkins web service的默认端口，将宿主机的端口映射到8080端口，可以直接访问
  3. –name 命名为prod_jenkins2
  4. -d 后台运行
  5. -p 端口映射
  6. -v 文件目录映射

docker container ls -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                     PORTS                   NAMES

启动后，可以直接通过url ‘http://localhost:9001‘ 访问，Jenkins首次打开，需要获取随机密码
