极狐gitlab ci job拉取代码之前执行命令

两种方法：

1. 一、在 ci job 中定义 hooks.pre_get_sources_script，此功能 15.6 版本引入，15.10 版本后功能默认开启 hookspre_get_sources_script：

   job1:
     hooks:
       pre_get_sources_script:
         - echo 'hello job1 pre_get_sources_script'
         - echo test44
     script: echo 'hello job1 script'

   执行结果：

     on docker runner x2QYBePa, system ID: r_HQ63Cf2vE2i9

   $ echo 'hello job1 script'
   hello job1 script
   Cleaning up project directory and file based variables
   00:00
   Job succeeded

2. 二、在 runner 中配置参数 pre_get_sources_script（在老版本的 runner 中，是设置 pre_clone_script，功能一样），参考：Runner Advanced configuration。这里以 docker runner executer 为例：

   concurrent = 10
   check_interval = 0
   user = "gitlab-runner"
   shutdown_timeout = 0
   
   [session_server]
     session_timeout = 1800
   
   [[runners]]
     name = "docker runner"
     url = "https://gitlab.leffss.cn"
     id = 0
     token = "xxxxxxxxxxxxxxxxxxxxxxxxxxx"
     token_obtained_at = 0001-01-01T00:00:00Z
     token_expires_at = 0001-01-01T00:00:00Z
     executor = "docker"
     environment = ["GO111MODULE=on", "GOPROXY=https://goproxy.cn,direct"]
     pre_get_sources_script = "eval \"$CI_PRE_CLONE_SCRIPT\""
     [runners.cache]
       Type = "s3"
       Shared = true
       MaxUploadedArchiveSize = 0
       [runners.cache.s3]
         ServerAddress = "10.10.10.60:9000"
         AccessKey = "minio"
         SecretKey = "minio123456"
         BucketName = "gitlab-cache"
         Insecure = true
     [runners.docker]
       tls_verify = false
       image = "busybox:1.28.4"
       privileged = true
       disable_entrypoint_overwrite = false
       oom_kill_disable = false
       disable_cache = false
       volumes = ["/certs/client", "/cache"]
       extra_hosts = ["gitlab.leffss.cn:10.10.10.60"]
       pull_policy = ["if-not-present"]
       shm_size = 0

   然后在 ci job 中的 CI_PRE_CLONE_SCRIPT 变量中指定需要运行的命令：

   job1:
     variables:
       CI_PRE_CLONE_SCRIPT: "echo CI_PRE_CLONE_SCRIPT\necho test2"
     script: echo 'hello job1 script'

   执行结果：

     on docker runner x2QYBePa, system ID: r_HQ63Cf2vE2i9

学习了，谢谢大神
