mise-s3-cache

Intelligent S3 caching for mise tool installations with automatic hook integration

Speed up your development workflows and CI/CD pipelines by automatically caching mise tool installations in S3. Share cached tools across your team and environments for dramatically faster builds. Now with seamless hook integration for zero-configuration setup!

Features

• 🚀 Automatic Hook Integration - Zero-configuration setup using mise hooks

📊 Performance Impact

Scenario	Before	After	Time Saved
Fresh installation	5 minutes	5 minutes	0%
Cached installation	5 minutes	30 seconds	90%
Team onboarding	5 min/developer	30 sec/developer	90%
CI builds (cached)	4-5 minutes	30-60 seconds	80-87%

🚀 Quick Start

1. Install mise-s3-cache

# Download latest release
curl -L https://github.com/fireboy1919/mise-s3-cache/releases/latest/download/mise-s3-cache-linux-x86_64.tar.gz | tar xz
sudo mv mise-s3-cache /usr/local/bin/

# Or install from source
git clone https://github.com/fireboy1919/mise-s3-cache.git
cd mise-s3-cache
cargo install --path .

2. Configure S3 credentials

# AWS credentials (same as AWS CLI)
export AWS_ACCESS_KEY_ID=your_access_key
export AWS_SECRET_ACCESS_KEY=your_secret_key
export AWS_DEFAULT_REGION=us-east-1

# S3 cache configuration  
export MISE_S3_CACHE_BUCKET=your-mise-cache-bucket
export MISE_S3_CACHE_ENABLED=true

3. Install hooks in your project

cd your-project
curl -O https://raw.githubusercontent.com/fireboy1919/mise-s3-cache/main/examples/install-hooks.sh
chmod +x install-hooks.sh
./install-hooks.sh

4. Use mise normally - caching is automatic!

mise install  # Tools are now automatically cached and restored

Installation

Using Cargo

cargo install mise-s3-cache

Download Binary

Download the latest release for your platform from GitHub Releases.

Using Homebrew (macOS/Linux)

brew install fireboy1919/tap/mise-s3-cache

Configuration

# Configure S3 bucket (required)
export MISE_S3_CACHE_BUCKET=your-cache-bucket
export MISE_S3_CACHE_REGION=us-east-1  # optional, defaults to us-east-1

# Test connectivity
s3-cache test

Configuration

Environment Variables

• MISE_S3_CACHE_BUCKET - S3 bucket name (required)
• MISE_S3_CACHE_REGION - AWS region (default: us-east-1)
• MISE_S3_CACHE_PREFIX - S3 key prefix (default: mise-cache)
• MISE_S3_CACHE_TTL - Cache TTL in seconds (default: 604800 = 7 days)

Project Configuration

# .mise.toml
[tools]
"s3-cache" = "latest"
node = "18.17.0"
terraform = "1.5.0"

[env]
MISE_S3_CACHE_BUCKET = "my-project-cache"

Usage

Once installed and configured, mise will automatically:

1. Check S3 cache before downloading tools
2. Download from S3 if available (fast, regional)
3. Fall back to upstream downloads if not cached
4. Store successful downloads in S3 cache (background)

Commands

# Check if a tool version exists in cache
s3-cache check node 18.17.0

# Restore a tool from cache
s3-cache restore node 18.17.0 --path ~/.mise/installs/node/18.17.0

# Store a tool installation in cache
s3-cache store node 18.17.0 --path ~/.mise/installs/node/18.17.0

# Analyze current project's cache status
s3-cache analyze

# Warm cache for current project
s3-cache warm

# Show cache statistics
s3-cache stats

# Show configuration status
s3-cache status

# Clean old cache entries
s3-cache cleanup --days 7

# Test S3 connectivity
s3-cache test

Integration with mise

To automatically use S3 cache with mise, you can create hooks or wrapper scripts:

#!/bin/bash
# ~/.local/bin/mise-with-cache

TOOL="$1"
VERSION="$2"
INSTALL_PATH="$3"

# Check cache first
if s3-cache check "$TOOL" "$VERSION"; then
    echo "📦 Restoring $TOOL@$VERSION from S3 cache"
    if s3-cache restore "$TOOL" "$VERSION" --path "$INSTALL_PATH"; then
        exit 0
    fi
fi

# Fallback to normal mise install
echo "⬇️  Installing $TOOL@$VERSION from upstream"
mise install "$TOOL@$VERSION"

# Cache the installation
s3-cache store "$TOOL" "$VERSION" --path "$INSTALL_PATH"

How It Works

1. Project Analysis: Parses .mise.toml and .tool-versions to identify required tools
2. Cache Check: Before any tool installation, checks if it exists in S3 cache
3. Fast Download: If cached, downloads from S3 (same region = fast)
4. Fallback: If not cached, uses normal mise installation
5. Background Caching: Successful installs are cached to S3 in background
6. Selective: Only tools in your project config are cached, preventing cache bloat

CI/CD Integration

Bitbucket Pipelines

- step:
    name: Build with S3 Cache
    script:
      - export MISE_S3_CACHE_BUCKET=your-cache-bucket
      - curl -sSL https://github.com/fireboy1919/mise-s3-cache/releases/latest/download/s3-cache-linux-x64.tar.gz | tar xz
      - chmod +x s3-cache
      - ./s3-cache warm  # Pre-cache project tools
      - mise install    # Will be much faster with pre-warmed cache
      - npm run build

GitHub Actions

- name: Setup S3 cache for mise
  run: |
    # Download and install s3-cache binary
    curl -sSL https://github.com/fireboy1919/mise-s3-cache/releases/latest/download/s3-cache-linux-x64.tar.gz | tar xz
    chmod +x s3-cache
    export PATH="$PWD:$PATH"
    
    # Configure and warm cache
    export MISE_S3_CACHE_BUCKET=your-cache-bucket
    s3-cache warm
    
    # Install mise and tools (will use cache)
    curl https://mise.run | sh
    mise install

Docker

FROM ubuntu:22.04

# Install s3-cache binary
RUN curl -sSL https://github.com/fireboy1919/mise-s3-cache/releases/latest/download/s3-cache-linux-x64.tar.gz | tar xz -C /usr/local/bin

# Configure S3 cache
ENV MISE_S3_CACHE_BUCKET=your-cache-bucket

# Install mise
RUN curl https://mise.run | sh

# Warm cache and install tools
COPY .mise.toml .
RUN s3-cache warm && mise install

Requirements

• mise 2024.1.0+ for tool management
• AWS credentials configured (via AWS CLI, environment variables, or IAM roles)
• S3 bucket with read/write permissions

Performance

Typical performance improvements with S3 cache:

• Node.js 18.17.0: ~2 minutes → ~10 seconds (12x faster)
• Terraform 1.5.0: ~30 seconds → ~3 seconds (10x faster)
• Python 3.11.0: ~3 minutes → ~15 seconds (12x faster)

Results vary based on network speed, S3 region, and tool size.

Security

• 🔐 Checksum Verification: All downloads verified with SHA256
• 🛡️ Input Validation: Tool names and versions sanitized
• 🚫 Path Traversal Protection: Prevents directory traversal attacks
• 📝 No Secrets in Logs: Careful handling of sensitive information
