Set AKS ConfigMap data for different environment using CICD pipeline

Question

I am deploying asp.net core application to AKS using Azure CICD pipeline.

I am copying below configMap deployment file from bild and use in release pipeline.

apiVersion: v1
kind: ConfigMap
metadata:
  name: akscicddemo-config
data:
  appsettings.json: |-
    {
      "Logging": {
        "LogLevel": {
         "Default": "Information",
         "Microsoft": "Warning",
         "Microsoft.Hosting.Lifetime": "Information"
        }
      },
      "AllowedHosts": "*",
      "AppSettings": {
        "Env": "prod"
        }
    }

Now i want to update above file data with Pipeline Variable. How can we update data in configMap file using release variable based on different environment (stages in pipeline).

Answer 1

I used Replace Tokens in CICD pipeline to replace specific keys from my config.yml file.

Updated Yml file

  apiVersion: v1
kind: ConfigMap
metadata:
  name: akscicddemo-config
data:
  appsettings.json: |-
    {
      "Logging": {
        "LogLevel": {
         "Default": "Information",
         "Microsoft": "Warning",
         "Microsoft.Hosting.Lifetime": "Information"
        }
      },
      "AllowedHosts": "*",
      "AppSettings": {
        "Env": "#{Env}#"
        }
    }
