1.下载镜像 

docker pull jenkins/jenkins:lts-centos

 2.创建/usr/local/docker/jenkins/Dockerfile文件及镜像

FROM jenkins/jenkins:lts-centos

USER root

# 安装docker
RUN yum install -y wget yum-utils device-mapper-persistent-data lvm2 && \
    yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo && \
    dnf install -y https://download.docker.com/linux/centos/7/x86_64/stable/Packages/containerd.io-1.2.6-3.3.el7.x86_64.rpm && \
    yum update -y && \
    yum install -y docker-ce

# 安装docker-compose
WORKDIR /usr/local/bin
RUN wget https://raw.githubusercontent.com/topsale/resources/master/docker/docker-compose
RUN chmod +x docker-compose
#COPY daemon.json /etc/docker/daemon.json

# 安装 Maven
WORKDIR /usr/local
COPY apache-maven-3.5.4-bin.tar.gz /usr/local
RUN tar -zxvf apache-maven-3.5.4-bin.tar.gz -C /usr/local/
RUN mv /usr/local/apache-maven-3.5.4/conf/settings.xml /usr/local/apache-maven-3.5.4/conf/settings.xml.bak
COPY settings.xml /usr/local/apache-maven-3.5.4/conf 

# 配置环境变量
ENV MAVEN_HOME /usr/local/apache-maven-3.5.4
ENV PATH $PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin

WORKDIR /

EXPOSE 8080
EXPOSE 50000

docker build -t  jiang-jenkins .

3.创建/usr/local/docker/jenkins/docker-compose.yml文件 

version: '3.1'
services:
  jenkins:
    image: 'jiang-jenkins'
    restart: always
    container_name: jiang-jenkins
    privileged: true
    ports:
      - 50000:50000
      - 9001:8080
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - ./jenkins_home:/var/jenkins_home
    networks:
      - jenkins_network
networks:
    jenkins_network:

4.创建jenkins_home目录（非ROOT用户改所有者）

mkdir jenkins_home

（chown -R 1000:1000 jenkins_home/）

5.执行docker-compose.yml文件 

docker-compose up 

6.登陆网站进行初始化配置
