Summary by CodeRabbit

• Chores
  • Specified required Terraform version and provider dependencies for the graceful_scale_in module to ensure compatibility.

Walkthrough

A new Terraform configuration file was added for the graceful_scale_in module, specifying the minimum required versions for Terraform and its providers (aws and cloudinit). This ensures compatibility and sets up provider dependencies for the module.

Changes

File(s)	Change Summary
src/modules/graceful_scale_in/versions.tf	Added required Terraform version and provider constraints configuration

Poem

A hop, a skip, a version set,
Dependencies aligned, no need to fret.
With cloudinit and AWS in tow,
The module’s ready—off we go!
Terraform’s rules now clear and bright,
Scaling in with versions right. 🐇✨

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

🧹 Nitpick comments (3)

src/modules/graceful_scale_in/versions.tf (3)

1-3: Specify upper bound for Terraform version
Using only ">= 1.0.0" allows Terraform 2.x, which may introduce incompatible changes. Consider constraining to the 1.x stream, for example:

required_version = "~> 1.0"

or by adding an upper bound (< 2.0.0) to ensure compatibility.

---

5-7: Constrain AWS provider versions for stability
The open-ended version = ">= 4.9.0" could pull in breaking 5.x releases. To lock into the 4.x minor stream, use a constraint like:

version = "~> 4.9.0"

This ensures you receive only non-breaking patch updates.

---

9-11: Constrain Cloudinit provider versions similarly
An open-ended ">= 2.2" may lead to unexpected major-version upgrades. Prefer a minor-pinned constraint such as:

version = "~> 2.2"

to guard against breaking changes.
