atlantis-gen-yaml

this tool generates projects section for your atlantis.yaml file by parsing your terragrunt file(s) and dependencies.

example case

let's assume we have a example-acm dir with this files next to our atlantis.yaml

$ find . -type f
./example-acm/record/terragrunt.hcl
./example-acm/certificate/terragrunt.hcl
./example-acm/validation/terragrunt.hcl
./atlantis.yaml

and content

example-acm/certificate/terragrunt.hcl

terraform {
  source = "../src"
}

inputs = {
  fqdn = "my-new-domain.example.com"
}

example-acm/record/terragrunt.hcl

terraform {
  source = "../src"
}

dependency "cert" {
  config_path = "../certificate"

  mock_outputs = {
    valid_name  = "fooBar"
    valid_type  = "CNAME"
    valid_value = "fooBar"
  }
}

inputs = {
  name  = dependency.cert.outputs.valid_name
  type  = dependency.cert.outputs.valid_type
  value = dependency.cert.outputs.valid_value
}

example-acm/validation/terragrunt.hcl

terraform {
  source = "../src"
}

dependencies {
  paths = ["../record"]
}

dependency "cert" {
  config_path = "../certificate"

  mock_outputs = {
    arn = "fooBar"
  }
}

inputs = {
  arn = dependency.cert.outputs.arn
}

running the binary

$ gen-atlantis-yaml -path example-acm

will produce YAML file with all dependencies from your terragrunt.hcl file(s).

custom atlantis config?

you can include custom atlantis variables by adding them to .atlantis-conf.yaml file e.q.

automerge: true
parallel_apply: false
parallel_plan: false
version: 3

would produce an atlantis.yaml file with the extra config files.
