The Current production [terraform version](https://github.com/FitnessKeeper/terraform-runkeeper#terraform-version) can be found here
### To create a new repo using the terraform-reference repo.

- Clone the repo `git clone https://github.com/FitnessKeeper/terraform-reference`
- Edit .env in the root of the repo, in particular make sure you add a TF_PROJECT_NAME
- Clone the repo into a new directory for your project `git clone https://github.com/FitnessKeeper/terraform-reference terraform-<project name>`
- Edit .env in the root of the repo, in particular make sure you add a TF_PROJECT_NAME (this should be the new name of the repo, `terraform-<project name>`)
- When creating a `spike` make sure you update TF_SPINE in env if something other then `rk` is needed, at the time of this writing `rk` and `asics` are valid spines.
- Also when creating ASICS `spikes` update to `TF_LOCK_TABLE=asics-services-terraformStateLock`
- If needed, set TF_STACK for the `stack` variable
- Initialize variables.tf, this only needs to be done once, when the repo is created run `./init-variables.tf.sh`
- Remove the old origin `git remote rm origin`
- Add your new repo `git remote add origin https://github.com/FitnessKeeper/terraform-reference.git`
- Add your new repo `git remote add origin https://github.com/FitnessKeeper/terraform-<project name>.git`
- Commit your changes
- `git push -u origin master`
- Edit variables.tf to reflect your new service
