Assistance with First Yaml pipeline in Azure DevOps - azure-devops

Question

I'm writing my first Terraform YAML pipeline in Azure DevOps. I define four repositories as resources, check them out and run to Terraform Plan. The pipeline succeeds but only the first repository of Terraform runs. This is based what is coming to the screen from that repositories' output.tf. The others don't generate any output even when I define a output variable with a string value. Something like this:
output "rg_module_debug" { value="rg module ran" }
Here is the pipeline code, any feedback on why the other code isn't running would be appreciated
name: 'Naming Test'
trigger:
- None
pool:
vmImage: ubuntu-latest
resources:
repositories:
- repository: VariablesRepo # identifier (A-Z, a-z, 0-9, and underscore)
type: git #git refers to Azure Repos Git repos
name: AzureTutorial/terraform-azurerm-variables-environment
ref: main
- repository: NameRepo # identifier (A-Z, a-z, 0-9, and underscore)
type: git #git refers to Azure Repos Git repos
name: AzureTutorial/terraform-azurerm-module-name
ref: main
- repository: NamingRepo # identifier (A-Z, a-z, 0-9, and underscore)
type: git #git refers to Azure Repos Git repos

- repository: ResourceGrpRepo # identifier (A-Z, a-z, 0-9, and underscore)

Answer 1

You are checking out multiple repositories therefore according to the documentation:
Multiple repositories:
If you have multiple checkout steps in your job, your source code is
checked out into directories named after the repositories as a
subfolder of s in (Agent.BuildDirectory). If (Agent.BuildDirectory) is
C:\agent_work\1 and your repositories are named tools and code, your
code is checked out to C:\agent_work\1\s\tools and
C:\agent_work\1\s\code.
Thus to achieve what you want you'd have to create one TerraformCLI#0 task for each checked out repository.
Therefore your stages code would be:
...
stages:
- stage: Install
jobs:
- job:
timeoutInMinutes: 60 # how long to run the job before automatically cancelling
cancelTimeoutInMinutes: 2 # how much time to give 'run always even if cancelled tasks'
before stopping them
steps:
- checkout: self
- checkout: VariablesRepo
- checkout: NameRepo
- checkout: NamingRepo
- checkout: ResourceGrpRepo
- task: TerraformInstaller#0
displayName: 'install'
inputs:
terraformVersion: 'latest'
- task: TerraformCLI#0
displayName: 'terraform init'
inputs:
provider: 'azurerm'
command: 'init'
workingDirectory: '$(System.DefaultWorkingDirectory)/NameRepo'
#environmentServiceName: TutorialSvcCon
- task: TerraformCLI#0
displayName: 'terraform plan'
inputs:
provider: 'azurerm'
command: 'plan'
workingDirectory: '$(System.DefaultWorkingDirectory)/NameRepo'
#environmentServiceName: TutorialSvcCon
If for instance you want to do the same operation for each repository then you add more tasks pointing to the RepositoryName as you correctly set up at the beginning:
- task: TerraformCLI#0
displayName: 'terraform init'
inputs:
provider: 'azurerm'
command: 'init'
workingDirectory: '$(System.DefaultWorkingDirectory)/VariablesRepo'
#environmentServiceName: TutorialSvcCon
- task: TerraformCLI#0
displayName: 'terraform plan'
inputs:
provider: 'azurerm'
command: 'plan'
workingDirectory: '$(System.DefaultWorkingDirectory)/VariablesRepo'
#environmentServiceName: TutorialSvcCon
And so forth.
