docker-compose安装Jenkins的实践笔记

创建目录

cd /usr/local/docker/ mkdir jenkins-docker cd jenkins-docker

创建Dockerfile

vi Dockerfile # 以下是文件内容 FROM jenkins/jenkins:lts USER root RUN mkdir -p /usr/local/ && cd /usr/local/ && curl -fsSL https://mirror.bit.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz > /usr/local/apache-maven-3.6.3-bin.tar.gz && tar xzf /usr/local/apache-maven-3.6.3-bin.tar.gz -C /usr/local/ && rm -rf /usr/local/apache-maven-3.6.3-bin.tar.gz && ln -s /usr/local/apache-maven-3.6.3/bin/mvn /bin/mvn && ln -s /usr/local/apache-maven-3.6.3/bin/mvnyjp /bin/mvnyjp && export PATH=/usr/local/apache-maven-3.6.3/bin:$PATH USER jenkins

构建镜像

docker build -t jenkins-jiacs:lts .

查看Docker在宿主机的Group ID

cat /etc/group | grep docker # [root@localhost jenkins-docker]# cat /etc/group | grep docker # docker:x:994: # 我这里的是994，根据各自的实际值而定

启动Jenkins容器(docker命令行启动)

# 启动容器之前先创建 /usr/local/docker/jenkins-docker/data 文件夹并赋予权限 # /usr/local/docker/jenkins-docker/config/settings.xml 该文件自行提供（可自定义私服等信息） mkdir data chmod -R 777 data docker run -d -p 8080:8080 -p 50000:50000 -v /usr/local/docker/jenkins-docker/data:/var/jenkins_home -v /etc/localtime:/etc/localtime:ro -v /var/run/docker.sock:/var/run/docker.sock -v /etc/docker:/etc/docker -v /usr/bin/docker:/usr/bin/docker -v /usr/local/bin/docker-compose:/usr/local/bin/docker-compose -v /usr/local/docker/jenkins-docker/config/settings.xml:/usr/local/apache-maven-3.6.3/conf/settings.xml –group-add=994 –name my-jenkins jenkins-jiacs:lts # 说明： # 1. -v /usr/local/docker/jenkins-docker/data:/var/jenkins_home =》持久化Jenkins数据 # 2. -v /etc/localtime:/etc/localtime:ro =》 设置Jenkins容器时间和宿主机一致 # 3. -v /etc/docker:/etc/docker =》 Jenkins容器中使用的docker为宿主机安装的docker，保证Jenkins部署的服务是在宿主机中启动的 # 4. -v /usr/local/bin/docker-compose:/usr/local/bin/docker-compose 如果宿主机安装了docker-compose，Jenkins容器需要使用的话可以加上该数据卷 # -v /usr/local/docker/jenkins-docker/config/settings.xml:/usr/local/apache-maven-3.6.3/conf/settings.xml # –group-add=994 让启动的容器用户组设置为宿主机中docker的用户组，保证在Jenkins容器中有权限操作宿主机的docker命令

启动Jenkins容器(docker-compose启动)

cd /usr/local/docker/jenkins-docker vi jenkins-docker.yaml version: 2 # 版本号不要修改，有些版本不支持group_add参数 services: jenkins: image: jenkins-jiacs:lts container_name: my-jenkins # restart: always ports: – 8080:8080 – 50000:50000 group_add: – 994 volumes: – ./data:/var/jenkins_home – /etc/localtime:/etc/localtime:ro – /var/run/docker.sock:/var/run/docker.sock – /etc/docker:/etc/docker – /usr/bin/docker:/usr/bin/docker – /usr/local/bin/docker-compose:/usr/local/bin/docker-compose – ./config/settings.xml:/usr/local/apache-maven-3.6.3/conf/settings.xml

启动

docker-compose -f jenkins-docker.yaml up -d

查看容器

docker ps

进入容器

docker exec -it 0d8b70ba5cec bash # 查看Jenkins初始密码（在容器中执行） cat /var/jenkins_home/secrets/initialAdminPassword

打开浏览器访问Jenkins服务

http://<宿主机IP>:8080/

将刚才查到的初始密码，填入

选择安装推荐的插件，等待插件的安装（这里耗时会久一点），如果部分插件安装失败，可以点击重试继续安装，或者记录失败的插件，到系统配置-插件配置中手动安装

修改Jenkins时区

系统管理 > 脚本命令行，输入一下命令，点击【运行】

System.setProperty(org.apache.commons.jelly.tags.fmt.timeZone, Asia/Shanghai)

安装完成
