Jenkins Docker 部署实践

docker-compose.yml

version: '3'                                    # 指定 docker-compose.yml 文件的写法格式
services:                                       # 多个容器集合
  docker_jenkins: 
    user: root                                  # 为了避免一些权限问题 在这我使用了root
    restart: always                             # 重启方式
    image: jenkins/jenkins:lts                  # 指定服务所使用的镜像 在这里我选择了 LTS (长期支持)
    container_name: jenkins                     # 容器名称
    ports:                                      # 对外暴露的端口定义
      - '7071:8080'
      - '50000:50000'
    volumes:                                    # 卷挂载路径
      - ./jenkins/jenkins_home/:/var/jenkins_home   # 这是我们一开始创建的目录挂载到容器内的jenkins_home目录
      - /var/run/docker.sock:/var/run/docker.sock
      - /usr/bin/docker:/usr/bin/docker                 # 这是为了我们可以在容器内使用docker命令
      - /usr/local/bin/docker-compose:/usr/local/bin/docker-compose     # 同样的这是为了使用docker-compose命令

run Create and start containers

1	docker-compose up -d

强制重新构建容器

1	docker-compose up -d --force-recreate

start

1	docker-compose start

stop

1	docker-compose stop

restart

1	docker-compose restart

dcoker 常用命令

# 查看镜像列表
docker images
# 删除镜像
docker rmi IMAGE ID
docker rmi -f IMAGE ID # 强制删除
# 删除未使用的镜像
docker image prune
# 列出所有在运行的容器信息
docker ps
# 查看所有运行或者不运行容器
docker ps -a
# 停止容器
docker stop CONTAINER ID
# 重启容器
docker restart CONTAINER ID
# 删除容器
docker rm CONTAINER ID
# 删除所有停止的容器
docker container prune
# 进入容器
docker exec -it jenkins /bin/bash

jenkins plugins

Docker
Docker Pipeline
Localization: Chinese (Simplified)
NodeJS Plugin
Simple Theme Plugin

QA

WorkflowScript: 3: Invalid agent type “docker” specified. Must be one of [any, label, none] @ line 3, column 9.

You have to install 2 plugins: Docker plugin and Docker Pipeline. Hope that helps.

/var/jenkins_home/workspace/htzxh5-test@tmp/durable-8063fe32/script.sh: 1: /var/jenkins_home/workspace/htzxh5-test@tmp/durable-8063fe32/script.sh: docker: Permission denied
/bin/sh: 12: sudo: not found

1 2	apt-get update && \ apt-get -y install sudo

Clear Jenkins build history

Jenkins home page -> Manage Jenkins -> Script Console.

def jobName = "project-name"  
def job = Jenkins.instance.getItem(jobName)  
job.getBuilds().each { it.delete() }  
job.nextBuildNumber = 1   
job.save()

docker in docker

The simple way to run Docker-in-Docker for CI

windows cannot touch ‘/var/jenkins_home/copy_reference_file.log’: Permission denied

The easy fix it to use the -u parameter. Keep in mind this will run as a root user (uid=0)

1	docker run -u 0 -d -p 8080:8080 -p 50000:50000 -v /data/jenkins:/var/jenkins_home jenkins/jenkins:lts
