在GitLab CI/CD作业中执行服务 [英] Exec into service in the context of GitLab CI/CD job

问题描述

我想使用GitLab CI/CD进行涉及两个容器的测试.该测试要求两个容器都启动，然后在其中一个容器中运行脚本(其语义类似于 kubectl exec ... script.sh 或 docker exec ...脚本.sh ).我已经尝试使用 服务 对此模型进行建模收到上一个答案:

I want to employ GitLab CI/CD for a test that involves two containers. The test requires that both containers are up and that a script is then run in one of them (with semantics akin to kubectl exec ... script.sh or docker exec ... script.sh). I've tried modeling this with services thanks to a previous answer received:

my_test:
  stage: test
  services:
  - my_image_2
  image: my_image_1
  script:
  - my_script.sh

但是，与此有关的问题是，现在有效的 my_script.sh 替换了 my_image_1 的入口点.然后，容器的行为会有所不同，这显然会使测试失败.是否有一种已知的模式可以克服这种情况，在概念上类似于 script:["docker exec ... script.sh"] ?

However, the problem with this is that my_script.sh now in effect replaces the entrypoint of my_image_1. The container then behaves differently and this obviously makes the test fail. Is there a known pattern for overcoming this situation, something conceptually akin to script: ["docker exec ... script.sh"]?

我考虑过还将 my_image_1 作为服务运行.但这是一个Web服务器，因此例如内部没有运行 sshd ，因此也没有外部连接可用于执行脚本.我还考虑过在 script:的第一步中添加/entrypoint.sh& ，但这似乎是一种hack，并且在第二步时还需要进行额外的运行状况检查，因为Web服务器在后台启动的速度相对较慢，因此必须延迟 my_script.sh (第3步).什么是前进的好方法?

I have considered running also my_image_1 as service. But it is a web server, so there is e.g. no sshd running inside, hence no outside connectivity for executing the script either. I've also considered adding /entrypoint.sh & as first step in script:, but this seems like a hack and would also require an additional health check as 2nd step, because the web server's start in the background will be relatively slow, so my_script.sh (the then 3rd step) would have to be delayed. What is a good way forward?

推荐答案

您可以覆盖入口点，并根据需要设置其行为.

You can override the entrypoint of the image specified with the entrypoint keyword and set it how you want it to behave.

my_test:
  stage: test
  services:
    - my_image_2
  image: 
    name: my_image_1
    entrypoint: [""]
  script:
    - my_script.sh
