Walkthrough

The recent updates to the FIAP.TechChallenge.ByteMeBurger solution involve the addition of several YAML configuration files and a stress test script. These changes enhance Kubernetes resource configurations, including a Horizontal Pod Autoscaler, a MySQL pod with persistent storage, and a custom StorageClass. Additionally, the deployment configuration for the API service has been updated to include new image references, liveness and readiness probes, and resource requests.

Changes

Files Change Summary
.../api-hpa.yaml Introduced a Horizontal Pod Autoscaler for scaling based on CPU utilization metrics.
.../deployment-api.yaml Updated image reference, added liveness and readiness probes, and set CPU resource requests.
.../pod-db-sc.yaml Defined a MySQL Pod with specific configurations, including volume mounts, ports, and persistent storage.
.../pvc-slow.yaml Added a PersistentVolumeClaim named pvc-db-slow with specific storage configurations.
.../sc-slow.yaml Introduced a StorageClass configuration named "slow" with specific provisioner and parameters.
.../stress.sh Added a script for running stress tests by making repeated HTTP requests to a local endpoint.

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>.
    • 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 generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @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.

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.

CodeRabbit Commands (invoked as PR comments)

  • @coderabbitai pause to pause the reviews on a PR.
  • @coderabbitai resume to resume the paused reviews.
  • @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.
  • @coderabbitai resolve resolve all the CodeRabbit review comments.
  • @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

40-42: The CPU resource request is minimal and should be monitored and adjusted based on actual usage.

Consider monitoring the CPU usage and adjusting the requests as necessary to optimize performance and cost.

Tip

Codebase Verification

The loop variable i is declared but not used within the loop body in kubernetes/stress.sh. This can be optimized by removing the unused variable.

  • Line 3: for i in {1..10000} ; do can be simplified to for _ in {1..10000} ; do to indicate that the loop variable is intentionally unused.
Analysis chain

Verify the usage of the loop variable i.

Scripts Executed

The following scripts were executed for the analysis:


Script:

#!/bin/bash
# Description: Check if the loop variable `i` is used elsewhere in the script.

# Test: Search for the variable `i` in the script. Expect: No occurrences outside the loop.
rg --type bash $'i' kubernetes/stress.sh

Length of output: 68
