How can I configure Atlantis to automatically generate a Terraform plan for a newly added subdirectory when utilizing a custom workflow

[mcarrillo-12]

Hello,

I’m a newcomer to Atlantis and have set up a custom workflow in one of my repositories. I’ve observed that each time I introduce a new directory containing Terraform code to my repository, the plan execution results in an error.

The error message is as follows:

Error: No configuration files
│ 
│ Plan requires configuration to be present. Planning without a configuration
│ would mark everything for destruction, which is normally not what is
│ desired. If you would like to destroy everything, run plan with the
│ -destroy option. Otherwise, create a Terraform configuration file (.tf
│ file) and try again.

Here’s the current configuration of my atlantis.yaml file in the repository:

# atlantis custom workflow
version: 3
automerge: true
projects:
- dir: imperva/terraform/customers
  workflow: waf-support
  autoplan:
    when_modified:
      - "**/*.tf"
    enabled: true

My goal is to configure Atlantis such that it automatically creates a plan whenever a new directory with code is added under the imperva/terraform/customers/ path.

If I specify the folder path in the custom workflow the plan works successfully

# atlantis custom workflow
version: 3
automerge: true
projects:
- dir: imperva/terraform/customers/customer1
  workflow: waf-support
  autoplan:
    when_modified:
      - "**/*.tf"
    enabled: true

Thanks a lot for all your help!

Found a way to do by just adding every single directory path like this

Server Side config

repos:
  - id: /.*/
    apply_requirements: [approved, mergeable]
    allowed_overrides: [workflow]

  - id: /my-repo/
    apply_requirements: [approved, mergeable]
    allowed_overrides: [workflow]
    allowed_workflows: [my-workflow]

# Define custom workflows
workflows:
my-workflow:
    plan:
      steps:
        - run:
            command: terraform init
            output: hide
        - run:
            command: my command --out PLANFILE
    apply:
      steps:
        - run: terraform apply $PLANFILE
  # add other custom workflows below

atlantis.yaml file on the repo. I created a script that will be adding new subdirectories to this file

version: 3
projects:
- dir: imperva/terraform/customers/customer1
  workflow: my-workflow
- dir: imperva/terraform/customers/customer2
  workflow: my-workflow
