在gitlab CI中，根据上一阶段的作业脚本指令的结果创建作业

Question

我想根据前一阶段作业脚本执行的结果来创建作业。例如，

variables:
  JOB2_CREATE=0

job_1:
  script:
    - JOB2_CREATE=1

# job 2 should only be created iff JOB2_CREATE is 1 which should get updated in job1.
job_2:
  on:
    variables:
      $JOB2_CREATE == 1
  script:
    - echo "job2 created and ran successfully"

我正在寻找类似的东西。我该如何实现？
