// bump Cztack (pronounced "stack") is CZI's collection of Terraform modules. We use these as way to scale our infrastructure work.

These modules are compatible with Terraform 0.12 and up.

Release-please managages all the releases. To make a release, merge the release PR.

To create a new module, copy the module-template directory and modify as you see fit. And make sure to add the module to the list of modules to test in .github/workflows/ci.yml.

A few notes on writing test for this repo. Note that this is new ground for us, so this will be a work in progress.

• To make modules testable, all fields that have a unique constraint need to be parameterizeable. Otherwise concurrent tests will conflict.
• It is tempting in testing module A to use module B to set up some context, but because terraform will just store the statefile locally, you can have a conflict.
  • We've tried to avoid this for now and set up context more directly
  • And also to not run tests in parrallel
  • and to clean up state files before and after each run
• our linter requires a test for each module. At the very least run init so that its syntax is checked. See an example here.
• AWS IAM is eventually consistent and supposedly is homed in us-east-1, so its probably best to run all tests that use IAM in that region.

• go
• terraform
• terraform-provider-bless - Place it in the same directory as your terraform executable. dirname \which terraform``
