• docker实例之jenkins


    说明:使用Dockerfile构建Jenkins实战记录

    环境:Ubuntu16.04

    1.部署包准备

    将如下部署包上传到/home/www/jenkins目录下并解压后重命名

    jdk-8u91-linux-x64.tar.gz

    apache-tomcat-9.0.8.tar.gz

    apache-maven-3.5.3-bin.tar.gz

    jenkins.war

    tar -zxvf jdk-8u91-linux-x64.tar.gz  && mv   jdk-8u91 jdk1.8

    tar -zxvf apache-tomcat-9.0.8.tar.gz && mv apache-tomcat-9.0.8 tomcat9

    tar -zxvf apache-maven-3.5.3-bin.tar.gz && mv apache-maven-3.5.3 maven3

    2.编写Dockerfile

    #cat Dockerfile

    FROM ubuntu
    MAINTAINER test@test.com
    COPY jdk1.8 /usr/local/jdk1.8
    COPY maven3 /usr/local/maven3
    COPY tomcat9 /usr/local/tomcat9
    ENV JAVA_HOME /usr/local/jdk1.8
    ENV PATH $JAVA_HOME/bin:$PATH
    ENV MAVEN_HOME /usr/local/maven3
    ENV PATH $PATH:$MAVEN_HOME/bin
    EXPOSE 8080
    CMD /usr/local/tomcat9/bin/startup.sh

    注意:这里最好使用拷贝的方式,不要使用ADD自动解压的方式,自动解压有时会出错,而且拷贝的是该目录下的文件,并不拷贝该目录,所以后面要加上目录

    提醒:如果这里遇到环境变量不生效,可以将其添加到/root/.bashrc

    3.构建镜像

    docker build -t jenkins:1.0   .    最后这个.不能忘记和省略

    构建实际过程如下

    # docker build -t jenkins:1.0 .
    Sending build context to Docker daemon 462.1MB
    Step 1/11 : FROM ubuntu
    ---> 735f80812f90
    Step 2/11 : MAINTAINER test@test.com
    ---> Running in 62a7dbef3184
    Removing intermediate container 62a7dbef3184
    ---> 82568cd558f0
    Step 3/11 : COPY jdk1.8 /usr/local/jdk1.8
    ---> 945586a8dcff
    Step 4/11 : COPY maven3 /usr/local/maven3
    ---> bc184ee94173
    Step 5/11 : COPY tomcat9 /usr/local/tomcat9
    ---> fc6d582bdb64
    Step 6/11 : ENV JAVA_HOME /usr/local/jdk1.8
    ---> Running in f5cad0490d63
    Removing intermediate container f5cad0490d63
    ---> 1f6e56c8bb71
    Step 7/11 : ENV PATH $JAVA_HOME/bin:$PATH
    ---> Running in 6b060ca76756
    Removing intermediate container 6b060ca76756
    ---> 1e170137b622
    Step 8/11 : ENV MAVEN_HOME /usr/local/maven3
    ---> Running in d917c5017e3f
    Removing intermediate container d917c5017e3f
    ---> 3acf26942c00
    Step 9/11 : ENV PATH $PATH:$MAVEN_HOME/bin
    ---> Running in 73307a90b9b0
    Removing intermediate container 73307a90b9b0
    ---> 3f6aaf6bddb6
    Step 10/11 : EXPOSE 8080
    ---> Running in b9e654185772
    Removing intermediate container b9e654185772
    ---> 4ed3514052be
    Step 11/11 : CMD /usr/local/tomcat9/bin/startup.sh
    ---> Running in b8266f7f5e8e
    Removing intermediate container b8266f7f5e8e
    ---> e9095cf5bd08
    Successfully built e9095cf5bd08
    Successfully tagged jenkins:1.0

    确认上面构建的容器

    # docker images
    REPOSITORY TAG IMAGE ID CREATED SIZE
    jenkins 1.0 2efe6942d56c About a minute ago 544MB

    4.创建容器

    docker run --privileged=true --net openwallet -d -it -p 10000:8080  -v /usr/local/tomcat9/webapps:/usr/local/tomcat9/webapps --name openwallet_jenkins jenkins:1.0 /bin/bash

    实际运行效果如下:

    # docker run --privileged=true --net openwallet -d -it -p 10000:8080 -v /usr/local/tomcat9/webapps:/usr/local/tomcat9/webapps --name openwallet_jenkins jenkins:1.0 /bin/bash
    4febf54c0fbfa3b067fda26308eb06b585bc296c378448ff40241a5dac965603

    5.防火墙策略

    在宿主机上安装ufw防火墙并添加规则

    宿主机的ip地址是192.168.30.36

    安装ufw防火墙工具#sudo apt-get install ufw

    #ufw enable
    #ufw default deny
    #ufw status
    Status: active

    添加策略

    ufw allow from 192.168.30.36 to any port 8080

    6.启动容器

    docker start  openwallet_jenkins      正常不用执行这个,上面执行之后会自动启动容器以及容器中的程序

    7.确认容器中的程序运行是否正常

    docker exec -it openwallet_jenkins /bin/bash

    mvn -version

    java -version

    ps -ef |grep tomcat

    如果Tomcat没启动,则需要手动启动下cd /usr/local/tomcat9/bin/startup.sh

    确认tomcat9/webapps目录下是否有jenkins.war文件,如果没有则需要拷贝

    docker cp jenkins.war openwallet_jenkins:/usr/local/tomcat9/weapps/

    8.登陆Jenkins并做对应设置

    http://192.168.30.36:10000/jenkins访问出现如下图片,显示为离线状态,解决方法如下:

    http://192.168.30.36:10000/jenkins/pluginManager/advanced    进入之后拉到最下面将https改成http提交之后重启Tomcat

    再次打开http://192.168.30.36:10000/jenkins正常按照提示到docker容器中执行命令获取密码

    # cat /root/.jenkins/secrets/initialAdminPassword
    8391c66d057244fca2a775de532050b3

    输入上面获取的密码按要求往下进行即可

    安装插件的时候选择“安装推荐的插件”----这一步持续差不多五分钟后就自动跳转到设置账号密码的地方了

    之后按照提示操作即可
