【K8S专题】七、使用 Docker 安装配置 Jenkins+Sonar（代码质量检查）

  实际项目应用开发过程中，单独为 SpringCloud 工程部署一台运维服务器，不要安装在 Kubernetes 服务器上，同样按照上面的步骤安装 docker 和 docker-compose，然后使用 docker-compose 构建 Jenkins 和 Sonar。

1. 创建宿主机挂载目录并赋权

mkdir -p /data/docker/ci/nexus /data/docker/ci/jenkins/lib /data/docker/ci/jenkins/home /data/docker/ci/sonarqube /data/docker/ci/postgresql

chmod -R 777 /data/docker/ci/nexus /data/docker/ci/jenkins/lib /data/docker/ci/jenkins/home /data/docker/ci/sonarqube /data/docker/ci/postgresql

2. 新建 Jenkins+Sonar 安装脚本 jenkins-compose.yml 脚本，这里的 Jenkins 使用的是 Docker 官方推荐的镜像 jenkinsci/blueocean，在实际使用中发现，即使不修改插件下载地址，也可以下载插件，所以比较推荐这个镜像。

      - ALL

3. 在 jenkins-compose.yml 文件所在目录下执行安装启动命令

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

安装成功后，展示以下信息

我们发现 jenkins 端口映射到了 18081 ，但是 sonarqube 没有启动，查看日志发现 sonarqube 文件夹没有权限访问，日志上显示容器目录的权限不够，但实际是宿主机的权限不够，这里需要给宿主机赋予权限

chmod 777 /data/docker/ci/sonarqube/logs
chmod 777 /data/docker/ci/sonarqube/bundled-plugins
chmod 777 /data/docker/ci/sonarqube/conf
chmod 777 /data/docker/ci/sonarqube/data
chmod 777 /data/docker/ci/sonarqube/extension

执行重启命令

docker-compose -f jenkins-compose.yml restart

再次使用命令查看服务启动情况，就可以看到 jenkins 映射到 18081，sonarqube 映射到 19000 端口，我们在浏览器就可以访问 jenkins 和 sonarqube 的后台界面了

5. Jenkins 登录初始化

从 Jenkins 的登录界面提示可以知道，默认密码路径为/var/jenkins_home/secrets/initialAdminPassword，这里显示的事 Docker 容器内部的路径，实际对应我们上面服务器设置的路径为/data/docker/ci/jenkins/home/secrets/initialAdminPassword ,我们打开这个文件并输入密码就可以进入 Jenkins 管理界面

6. 选择安装推荐插件，安装完成之后，根据提示进行下一步操作，直到进入管理后台界面

7. 默认配置

• sonarqube 默认用户名密码: admin/admin
• 卸载命令：docker-compose -f jenkins-compose.yml down -v
