Helm Values Explorer 🎡

🚀 Navigate Helm values across multiple environments with ease!

A Visual Studio Code extension that enhances your Helm chart development experience by providing instant value previews from multiple environment-specific values files.

✨ Features

• 🔍 Smart Value Preview: Hover over any {{ .Values.* }} expression to instantly see values
• 🌍 Multi-Environment Support: View values from multiple files (e.g., values.yaml, dev-values.yaml, prod-values.yaml)
• 📁 Intelligent File Detection: Automatically finds values files in current and parent directories
• 🎯 Zero Configuration: Works out of the box with any Helm chart
• 💪 Rich Value Display: Shows properly formatted YAML with clear source labeling

📦 Installation

1. Open Visual Studio Code
2. Press Ctrl+P / Cmd+P to open the Quick Open dialog
3. Type ext install rossp.helm-values-explorer and press Enter

🚀 Usage

1. Open a Helm chart directory in VS Code
2. Navigate to any template file (e.g., templates/deployment.yaml)
3. Hover over any {{ .Values.* }} expression to see values from all matching files

Example

Given these files:

mychart/
├── values.yaml         # Default values
├── dev-values.yaml     # Development overrides
├── prod-values.yaml    # Production overrides
└── templates/
    └── deployment.yaml

When hovering over {{ .Values.image.repository }}, you'll see:

[values.yaml] image.repository: nginx
[dev-values.yaml] image.repository: nginx-dev
[prod-values.yaml] image.repository: nginx-prod

• helmValuesExplorer.valueFiles: Patterns to match Helm values files (default: ["values.yaml", "*values.yaml", "values.*.yaml"])
