All runners are tested on every push via the CI workflow.

• 🔥 rmz Support: Use rmz for up to 3x faster file deletion
• 🛠️ DevContainer: Full development environment with Docker-in-Docker
• ✅ Pre-commit Hooks: Automated code quality checks with shellcheck and actionlint
• 📦 Workflow Templates: Refactored tests using reusable workflows
• 🔧 Better Error Handling: Improved validation and error messages
• 📝 Enhanced Documentation: Complete API reference and examples

The v3 is fully backward compatible with v2. To migrate:

# Before (v2)
- uses: endersonmenezes/free-disk-space@v2
  with:
    remove_android: true

# After (v3) - works the same
- uses: endersonmenezes/free-disk-space@v3
  with:
    remove_android: true
    
# After (v3) - with new features
- uses: endersonmenezes/free-disk-space@v3
  with:
    remove_android: true
    rm_cmd: "rmz"        # NEW: Faster deletion
    rmz_version: "3.1.1" # NEW: Specify rmz version

Breaking Changes: None! All v2 configurations work in v3.

New Optional Parameters:

• rm_cmd: Choose between rm (default) or rmz (faster)
• rmz_version: Specify rmz version when using rm_cmd: rmz

Free Disk Space Action are inspired by jlumbroso/free-disk-space

At work I came across a huge Docker image that still needed to be analyzed by a local security tool. This consumed the entire Runner and in addition to the repository I found, I needed to remove some packages, which led me to create a modification of the original repository.

I will maintain a Stable version of this project.

name: Free Disk Space (Ubuntu)
on:
  - push

jobs:
  free-disk-space:
    runs-on: ubuntu-latest
    steps:
      - name: Free Disk Space
        uses: endersonmenezes/free-disk-space@v3  # Use @main for latest, @v3 for stable
        with:
          remove_android: true
          remove_dotnet: true
          remove_haskell: true
          remove_tool_cache: true
          remove_swap: true
          remove_packages: "azure-cli google-cloud-cli microsoft-edge-stable google-chrome-stable firefox postgresql* temurin-* *llvm* mysql* dotnet-sdk-*"
          remove_packages_one_command: true
          remove_folders: "/usr/share/swift /usr/share/miniconda /usr/share/az* /usr/local/lib/node_modules /usr/local/share/chromium /usr/local/share/powershell /usr/local/julia /usr/local/aws-cli /usr/local/aws-sam-cli /usr/share/gradle"
          rm_cmd: "rm"  # Use 'rmz' for faster deletion (default: 'rm')
          rmz_version: "3.1.1"  # Required when rm_cmd is 'rmz'
          testing: false

- name: Free Disk Space for Docker
  uses: endersonmenezes/free-disk-space@v3
  with:
    remove_android: true
    remove_dotnet: true
    remove_haskell: true
    rm_cmd: "rmz"  # Faster cleanup
    
- name: Build Docker Image
  run: docker build -t myapp:latest .

- name: Free Disk Space for Node
  uses: endersonmenezes/free-disk-space@v3
  with:
    remove_android: true
    remove_haskell: true
    remove_packages: "google-cloud-cli azure-cli"
    
- name: Install Dependencies
  run: npm ci

- name: Free Disk Space for Python
  uses: endersonmenezes/free-disk-space@v3
  with:
    remove_android: true
    remove_dotnet: true
    remove_folders: "/usr/share/swift /usr/local/julia"
    
- name: Install Python Packages
  run: pip install pandas numpy scikit-learn

For faster file deletion, you can use rmz instead of the default rm command:

- name: Free Disk Space (with rmz)
  uses: endersonmenezes/free-disk-space@v3
  with:
    remove_android: true
    remove_dotnet: true
    rm_cmd: "rmz"  # Faster deletion (~3x faster)
    rmz_version: "3.1.1"

Note: rmz is a Rust-based alternative to rm, providing significantly faster deletion for large directories. Learn more at SUPERCILEX/fuc.

• ⚡ rmz is significantly faster for large operations (up to 88% faster on Android folder, 64% on Large removal)
• 🔧 ARM runners now have more pre-installed software, freeing up to 16 GB with Large removal
• 📊 Full cleanup on x86_64 can free up to 41 GB with Large removal
• 🎯 For maximum speed: Use rmz with remove_packages_one_command: true

The time can vary according to multiple factors. These measurements are based on Run #234

In our action you can see more folders and packages to delete, but it is your responsibility to know what you are doing.

Initially I created this project with the intention of doing all this and then being able to use Docker and Python, our tests will prove this.

Q: Should I use rm or rmz?

• Use rm (default) for compatibility and safety
• Use rmz when you need maximum performance

Q: How much time does this save in my CI/CD?

• Typical savings: 2-5 minutes per workflow run
• With rmz: Up to 3x faster deletion operations

Q: Is it safe to remove all these packages?

• The defaults are safe for most workflows
• Test with your specific needs first
• Use testing: true to see what would be removed

Q: How can I debug issues?

• Enable disk space logging before and after (see examples above)
• Use testing: true to see what would be removed without actually removing
• Check the AGENTS.md for troubleshooting details
