For complex projects that may require a migration over a protracted period we recommend utilizing Terraform to simplify the process of quickly switching back should a problem arise to avoid disruption.

The following demonstrates manging a variety of group variables, as described in the other migration documentation, in combination with our enhanced runner module.

To switch between runners simply toggle the value of local.cedari and apply the configuration.

locals {
  cedarci = true
  variables = local.cedarci ? {
    CEDARCI = "true"
    COMPLEX_CONFIG = "value2"
    TAG_LARGE = "cedarci"
    TAG_SMALL = "cedarci"
  } : {
    COMPLEX_CONFIG = "value1"
    TAG_LARGE = "saas-linux-large-amd64"
    TAG_SMALL = "saas-linux-small-amd64"
  }
}

data "gitlab_group" "default" {
  full_path = "path/to/group"
}

resource "gitlab_group_variable" "variables" {
  for_each = local.variables
  group = data.gitlab_group.default.id
  key = each.key
  value = each.value
}

module "cedarci" {
  source = "git::git@gitlab.com:cedarci/integration/terraform_cedarci.git?ref=main"
  config_user = "speedy"
  gitlab_group = data.gitlab_group.default.full_path
}
