Azure pipeline dynamic creation of variables based on parameters

0 votes

I've included an azure-pipeline.yml file that references templates for auditing, testing, building, and deployment.

What I need to work on is piping Azure DevOps Library values/secrets. The catch is that each search refers to different strings/secrets.

E.g. The node.js services have this service A has a cache connection string as process.env.CACHE_CONNECT service B has a cache connection string as process.env.CACHE_CONNECTION_STRING service C has a cache connection string as process.env.CONNECT_TO_CACHE

I intend to pass in a parameter list and then map over it to create variables that can be used in multiple places and also passed into the docker build/deploy steps.

The issue is creating variable key/value pairs dynamically.

Is this a possibility? Is there a better way to approach this?

name: CD

parameters:
- name: environment
  type: object
  default:
  - foo
  - bar
- name: dotEnvPairs
  type: object
  default:
  - envKey: 'NODE_ENV'
    libraryKey: Production
  - envKey: 'CACHE_STRING'
    libraryKey: 'testMe'

variables:
- group: WebDevelopment   

trigger:
- main

pool:
  vmImage: ubuntu-latest

steps:

- ${{ each value in parameters.dotEnvPairs }}:

# The goal is to do something like this:
# <value.envKey> = <variableGroup<value.libraryKey>
  - script: |
      echo Env name is ${{ value.envKey }}
      echo Env value is ${{ value.libraryKey }}
      echo Static key $(testMe)
      echo Dynamic A key %$(value.libraryKey)%
      echo Dynamic B key %${{value.libraryKey}}%
      echo Dynamic C key %$(variables[value.libraryKey]: value)%

I'm automating service deployment, but I can't touch any of the base code at this time.
