在管道任務中指定運行時參數 (Specify runtime parameter in a pipeline task)

問題描述

在管道任務中指定運行時參數 (Specify runtime parameter in a pipeline task)

我們需要以某種方式將動態運行時參數傳遞給管道任務。例如下面的參數 APPROVAL 對於任務的每次運行都是不同的。此 APPROVAL 參數用於更改和發布編號，以便任務可以在為審計目的而創建的 Terraform 資源上標記它。

在網上搜索了一段時間但沒有找到解決方案，是這可能在大廳管道或最佳實踐中？

  ‑ task: plan‑terraform
    file: ci/concourse‑jobs/pipelines/tasks/terraform/plan‑terraform.yaml
    params:
      ENV: dev
      APPROVAL: test
      CHANNEL: Developement
      GITLAB_KEY: ((gitlab_key))
      REGION: eu‑west‑2
      TF_FOLDER: terraform/squid
    input_mapping:
      ci: ci
      tf: squid
    output_mapping:
      plan: plan
    tags:
    ‑ dev

參考解法

方法 1:

From https://concourse‑ci.org/tasks.html: ideally tasks are pure functions: given the same set of inputs, it should either always succeed with the same outputs or always fail.

A dynamic parameter would break that contract and produce different outputs from the same set of inputs. Could you possibly make APPROVAL an input? Then you'd maintain your build traceability. If it's a (file) input, you could then load it into a variable:

APPROVAL=$(cat <filename>)
