Golang 代码质量持续检测

Author: Kenny Allen

Email: [email protected]

前言

在软件开发过程中，人工检查项目代码中的漏洞和潜在的 BUG 是一件让人十分费神费力的事情，为了解决这一痛点，SonarQube诞生了，它实现了一系列代码自动检测过程，包括命名规范，代码漏洞，代码重复量等。

但是光有 SonarQube 还不能发挥出应有的高效率，一个完整的代码质量持续检测应配合代码仓库(如 gitlab) 和 Jenkins 来共同构建一个自动化过程。

环境

• Gitlab、Jenkins、SonarQube 服务都在一台物理机上的Docker中运行

• 网络 (局域网IP：192.168.1.100)

• 主机科学上网代理

  192.168.1.100:1087

  

• 模拟外网访问

  # 修改 hosts 文件，模拟外网访问
  sudo sh -c "echo '192.168.1.100 jenkins.kenny.com\n192.168.1.100 gitlab.kenny.com\n192.168.1.100 sonarqube.kenny.com' >> /etc/hosts"

  

• 工具集

搭建

接下来，我以一个完整的案例来介绍搭建过程。

Jenkins

启动服务

# $jenkins_home 宿主机目录，挂载容器 /var/jenkins_home
# 我的数据卷目录是 ~/.jenkins
export JENKINS_HOME=~/.jenkins
docker run -d --restart=always -p 8080:8080 -p 50000:50000 -v $JENKINS_HOME:/var/jenkins_home --name jenkins jenkins:2.60.3

# 查看 jenkins 日志
docker logs -f jenkins

初始化

1. 打开浏览器，访问 http://jenkins.kenny.com:8080

   

   # 在日志中找到管理员密码
   docker logs -f jenkins 
   
   # 或者在 $JENKINS_HOME/secrets/initialAdminPassword 文件中找到管理员密码
   cat $JENKINS_HOME/secrets/initialAdminPassword

   

   

2. 安装推荐插件 (如果你想自定义安装插件，点击 Select plugins to Install)

   

3. 创建管理员账号

   

4. 初始化完成

   

Gitlab

启动服务 (gitlab 集成的服务比较多，因此需要占用较大的内存，官方推荐4GB以上)

# $gitlab_home 宿主机目录
# 我的数据卷目录是 ~/.gitlab
export GITLAB_HOME=~/.gitlab
docker run -d --restart=always -e 'GITLAB_HOST=gitlab.kenny.com' -p 443:443 -p 80:80 -p 22:22 -v $GITLAB_HOME/conf:/etc/gitlab -v $GITLAB_HOME:/var/opt/gitlab -v $GITLAB_HOME/log:/var/log/gitlab --name gitlab gitlab/gitlab-ce:11.1.0-ce.0

# 查看 gitlab 日志
docker logs -f gitlab

初始化

1. 打开浏览器，访问 http://gitlab.kenny.com

   

2. 设置新密码后，使用 root 用户登录

   

   

3. 新建 sonarqube 项目组

   

4. 在 sonarqube 项目组下新建 demo 项目

   
   

5. 添加主机公钥到 Gitlab

   # 生成 rsa 公钥和密钥
   ssh-keygen -t rsa
   
   # 查看并复制公钥
   cat ~/.ssh/id_rsa.pub

   

   

   访问 http://gitlab.kenny.com/profile/keys ，将公钥添加至 Gitlab

   

   

6. 将 sonarqube/demo 项目拉至主机的 $GOPATH 下

   # 在 $GOPATH 下创建 gitlab.kenny.com 文件夹
   mkdir -p $GOPATH/src/gitlab.kenny.com && cd $GOPATH/src/gitlab.kenny.com
   
   # clone code
   git clone [email protected]:sonarqube/demo.git

SonarQube

启动服务

# 由于目前 sonarqube 官方的 Docker images 只有 7.1 版本，不满足 SonarGO 所需 7.2+ 版本，所以我参考7.1 的 Dockerfile 制作了一个 sonarqube 7.2.1 的镜像
# $sonarqube_home 宿主机目录
# 我的数据卷目录是 ~/.sonarqube
export SONARQUBE_HOME=~/.sonarqube
# 正式环境中应启用外部数据库服务来存储必要数据，在启动容器时设置如下JDBC相关参数:
# -e SONARQUBE_JDBC_USERNAME=sonar 
# -e SONARQUBE_JDBC_PASSWORD=sonar 
# -e SONARQUBE_JDBC_URL=jdbc:postgresql://localhost/sonar
docker run -d --restart=always -p 9000:9000 -v $SONARQUBE_HOME:/opt/sonarqube/data --name sonarqube kennyallen/sonarqube:7.2.1

# 查看 sonarqube 日志

Dockerfile:

FROM openjdk:8

ENV SONAR_VERSION=7.2.1 \
    SONARQUBE_HOME=/opt/sonarqube \
    SONARQUBE_JDBC_USERNAME=sonar \
    SONARQUBE_JDBC_PASSWORD=sonar \

  -Dsonar.jdbc.url="$SONARQUBE_JDBC_URL" \
  -Dsonar.web.javaAdditionalOpts="$SONARQUBE_WEB_JVM_OPTS -Djava.security.egd=file:/dev/./urandom" \
  "$@"

初始化

1. 打开浏览器，访问 http://sonarqube.kenny.com:9000

   

2. 使用管理员账号登录

   • 账号 admin
   • 密码 admin

   

3. 生成 token (作为远程连接 SonarQube 的标识，只生成一次，记得备份哦)

我们有个前端同事 的个人blog就写在issue里面的，还可以评论,检索

https://reading.hidevops.io

这是今天春晖大佬要讲的内容，我从滴滴内网上找到的资料，晚上一定要勾搭上曹大。

推荐大家阅读，建议大家以后夜读之前一定要提前预习，并且提议参与夜读的同学每人至少准备一个问题，可以随时提问。好处：提高参会者参与感，提前预习，带着问题也会更有效率；提高主讲人的存在感，上次我分享的时候，感觉全程就我一人存在，没有反馈，体验不太好。

Night Reading Go - Go source reading and offline technical discussion every Thursday night.

ReadMe.md 日常讨论总结：

大部分链接有问题了..

第 32 期 Go 夜读之 etcd raft 源码阅读预习材料：

https://github.com/developer-learning/night-reading-go/blob/master/content/reading/32-2019-03-02-etcd-raft.md

sync.Once源码分析中Do方法的注释有一部分有问题：

func (o *Once) Do(f func()) {
        //......
	if o.done == 0 {
	        // 原注释：先将done设置为1，再执行f函数
                defer atomic.StoreUint32(&o.done, 1)
		f()
	}
}

1. done不会先设置为1，而是在退出Do函数时设置为1
2. defer在此处还有另一个用意——即便f()发生panic仍会在退出Do函数时将0.done设置为1
   • 由此引发的另一个问题是调用者需要确认：你的f()正确执行，你保存的once对象也是与f()正确执行时对应的那个once对象
   • 一旦f()发生错误要重新创建once对象再调用once.Do(f)（绝不可复用前一个once对象）
   • 若f()成功则保留该once对象，不成功重复上面的过程

kubernetes有录像吗

当我们clone一个.mod的go项目的时候，一般我们只要使用go mod tidy就可以找到我们所需要的相关依赖包，但是在goland中，我们需要注意，具体如下图：

如图所示：我们需要在goland中将mod打开，否则goland会找不到对应的module文件。

之后重启 goland 即可

获取昨天时间：
timeCST := time.Now()
yesTime := timeCST.AddDate(0, 0, -1) // 能得到昨天时间
若在循环中，例如for i:=0, i<5，i++
yesTime := timeCST.AddDate(0, 0, -i+1)
的循环中，为什么从后天开始往前计算。而不是直接往前推5天。

这个里面提到，Nginx 是工作在网络层（第七层）

其实Nginx 是可以做网络层（第四层）的负载均衡的。比如做mysql 的负载均衡。

现在更新某子项目的时候会存在同时要同步两个 README.md ，是否可以做到添加文件后自动更新呢？
