github上每年都有很多起因密钥或密码等机密数据泄露的事件，比如有aws的密钥，oss桶密钥等，有的甚至被人利用创建了云主机进行了挖矿。。

这里推荐一款代码库扫描工具–gitleaks，github上有15k的start。

• 环境搭建：

还是使用docker镜像启动，挂载需要检测的code目录

$ cat docker-compose.yml
version: '3'
services:
  gitleaks-test:
    container_name: gitleaks-test
    hostname: gitleaks-test
    restart: always
    image: zricethezav/gitleaks:v8.18.2
    tty: true
    stdin_open: true
    volumes:
      - ./leakcheck:/code
    entrypoint: bash

• gitleaks命令行参数
