configuring Atlantis to support multiple account terragrunt files

[skkc2]

Hi All,

I'm working on Atlantis recently I have a requirement to make it support Terragrunt which has multiple accounts.

I couldn't find enough info to achieve this, apologies in advance if this question is silly can someone assist with this?

My terragrunt structure has multiple accounts folders and each account folder has multiple resources and all of these are under one repo.

live/
├── terragrunt.hcl
├── dev
│   ├── eu-west-1
          ├── vpc
          ├── ec2
          ├── R53
│   ├── global
│   └── us-east-1
├── prod
│   ├── global
│   └── us-east-1
└── stage
    ├── eu-west-1
    ├── us-east-1
    └── global

If a user creates pull/merge request How can i achieve that atlantis executes terragrunt plan / apply specfic to that aws account only.

below is my atalntis_config file , repos.yaml and atlantis.yaml. All of these are on my jenkins server

atlantis server
--atlantis-url="https://private_ip:4141" \
--gitlab-hostname="https://gitlab.private.cloud/"
--gitlab-user="git_user"
--gitlab-token="ABCDEFGHIKJLETCj"
--gitlab-webhook-secret="abcdefgh123456789"
--repo-allowlist="*"
--repo-config="./repos.yaml"

Repos.yaml

repos:
- id: /.*/
  allowed_overrides: [workflow]
  allowed_workflows: [terragrunt]
  pre_workflow_hooks:
    - run: "cat ~/atlantis/atlantis.yaml > atlantis.yaml"

workflows:
  terraform:
    plan:
      steps:
      - init
      - plan:
          extra_args: ["-var-file=testing.tfvars"]
    apply:
      steps:
      - apply

Atlanstis.yaml

version: 3
projects:
- dir: .
  workflow: terragrunt
  autoplan:
    enabled: true

Thanks
