Walkthrough

The changes update the main.tf file in the EKS module configuration. The Kubernetes provider's exec block now uses a more stable API version (client.authentication.k8s.io/v1beta rather than v1beta1). In addition, the minimum healthy percentage for instance refreshes in the self-managed node group defaults has been raised from 66 to 80, enforcing a stricter threshold during rolling updates. There are no changes to exported or public entities.

Changes

File	Change Summary
main.tf	- Updated Kubernetes provider api_version from "client.authentication.k8s.io/v1beta1" to "client.authentication.k8s.io/v1beta" - Increased min_healthy_percentage from 66 to 80 in instance_refresh settings

Poem

In the land of code, I softly hop,
Where API shifts make the config pop,
A version updated, a threshold now high,
Healthy nodes march as the updates fly,
With twitching whiskers, I cheer—a bunny’s delight on the fly! 🐇✨

9-14: API Version Update in Kubernetes Exec Block.
The exec block for the Kubernetes provider now uses "client.authentication.k8s.io/v1beta", which reflects a more stable API version. Please verify that this version is fully supported by your AWS CLI and the Kubernetes provider version in use, to ensure backwards compatibility and avoid unexpected behavior.

126-130: Increased Minimum Healthy Percentage for Instance Refresh.
The min_healthy_percentage in the instance_refresh preferences for the self-managed node group defaults has been raised from 66 to 80. This stricter threshold requires a higher proportion of healthy instances during rolling updates, which improves stability but may also slow down updates if the new instances take longer to become healthy. Please verify that this change aligns with your operational tolerance and won't inadvertently cause prolonged update cycles.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

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.
