yk8s.terraform

Gitlab Terraform backend

To activate automatic backend of Terraform statefiles to Gitlab, adapt the Terraform section of your config: set yk8s.terraform.gitlab_backend to true, set the URL of the Gitlab project and the name of the Gitlab state object.

terraform = {
  gitlab_backend    = true;
  gitlab_base_url   = "https://gitlab.com";
  gitlab_project_id = "012345678";
  gitlab_state_name = "tf-state";
};

Put your Gitlab username and access token into the ~/.config/yaook-k8s/env. Your Gitlab access token must have at least Maintainer role and read/write access to the API. Please see GitLab documentation for creating a personal access token.

To successful migrate from the “local” to “http” Terraform backend method, ensure that yk8s.terraform.gitlab_backend is set to true and all other required variables are set correctly. Incorrect data entry may result in an HTTP error respond, such as a HTTP/401 error for incorrect credentials. Assuming correct credentials in the case of an HTTP/404 error, Terraform is executed and the state is migrated to Gitlab.

To migrate from the “http” to “local” Terraform backend method, set yk8s.terraform.gitlab_backend to false, MANAGED_K8S_NUKE_FROM_ORBIT=true, and assume that all variables above are properly set and the Terraform state exists on GitLab. Once the migration is successful, unset the variables above to continue using the “local” backend method.
