Current Behavior or Linked Issues


  • AKS running in v1.24.4 which has being deprecated by Microsoft.
  • The condition Which was added in 772 is not working as skip is not a parameter which is being passed and throwing below error
  • Job Build_service_resources_dev: Step specifies condition and(succeeded(), not(coalesce(variables.SKIP_TESTS, ))) which is not valid. Reason: Unexpected symbol: ')'. Located at position 53 within expression: and(succeeded(), not(coalesce(variables.SKIP_TESTS, ))). For more help, refer to https://go.microsoft.com/fwlink/?linkid=842996

Does this introduce a breaking change?


  • [YES]

  • This will upgrade the aks from 1.24.x to 1.25.x. Some of the API versions are deprecated which were already stated in the document

  • azurerm_kubernetes_service_versions is introduced to fetch the latest patch version given the major.minor version

  • zones are modified to resolve the issue 777#note_199389 since the public Ip either accept the single zone or it will be created as zone redundandant. It will not accept 2 zones so modified the gateway zones to include all the 3 zones. more info azure-public-ip-availability-zone. These scripts are tested in dev environment using multiple runs and they are success

  • Changed the parameter from skip to skipTests Since skip is not a parameter. resolving the issues in MR 772
