Summary of Changes

Hello @TatsukiMinami, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on modernizing the project's infrastructure dependencies and development toolchain. It ensures that the cluster creation process leverages more recent and potentially more stable versions of key components like Cilium and ingress-nginx. Additionally, it updates the local development environment tools and activates automated dependency management through Renovate, aiming to improve maintainability and keep the project up-to-date with minimal manual intervention.

Highlights

• Dependency Version Updates: Updated Helm chart versions for Cilium and ingress-nginx in helmfile.yaml to their latest stable releases.
• Tool Version Bumps: Increased the versions of various development tools including KIND, KUBECTL, CILIUM_CLI, HELM, and HELMFILE in the install-tools.sh script.
• Renovate Bot Activation: Enabled the Renovate bot by updating the renovate.json configuration, allowing for automated dependency updates.

Code Review

This pull request updates dependencies for various tools and Helm charts, and enables Renovate for automated dependency management. While enabling Renovate is a great step, the manual version updates in install-tools.sh and helmfile.yaml appear to use non-existent versions for all tools and charts. This will cause the installation script and Helmfile deployment to fail. I've left specific comments pointing out the invalid versions. Please correct these to valid, existing versions.

[gemini-code-assist]

The specified chart versions for Cilium and ingress-nginx appear to be invalid.

• cilium: version 1.18.6 does not seem to exist. The latest stable version is in the 1.15.x range.
• ingress-nginx: version 4.14.1 does not seem to exist. The latest stable version is in the 4.10.x range.

Using non-existent chart versions will cause helmfile to fail. Please update these to valid, available chart versions.

[gemini-code-assist]

The versions specified for the tools to be installed appear to be incorrect and will likely cause the installation script to fail.

• KIND_VERSION: v0.31.0 does not seem to be a valid release. The latest version is v0.23.0.
• KUBECTL_VERSION: v1.35.0 is not a valid Kubernetes release version. The latest is v1.30.0.
• CILIUM_CLI_VERSION: v0.19.0 is not a valid version for cilium-cli. The latest is v0.16.10.
• HELM_VERSION: v4.1.0 is a major version bump, and Helm v4 has not been released yet. The latest stable version is in the v3.x series.
• HELMFILE_VERSION: 1.2.3 does not seem to be a valid version. The latest version is v0.165.0.

Please verify the correct versions for these tools to ensure the script can download and install them successfully.
