🐳 S3Docker

🎯 Why S3Docker?

Managing Docker images across multiple environments and teams can be challenging:

• Private registries can be expensive and complex to maintain
• Manual image transfer is time-consuming and error-prone
• Version management and rollbacks can be difficult

S3Docker solves these problems by:

• Using AWS S3 as a cost-effective storage solution
• Providing simple commands for image management
• Automatically handling versioning and archiving
• Supporting multiple configuration profiles for different environments

✨ Features

• 📦 Simple push/pull commands for Docker images
• 🔄 Automatic version archiving
• 📝 Multiple named configuration profiles
• 📊 Image listing with size and modification info
• 🧹 Automatic cleanup of temporary files
• 🔒 Secure AWS credentials management

🚀 Installation

pip install s3docker

📋 Prerequisites

• Python 3.6 or higher
• Docker installed and running
• AWS account with S3 access
• AWS credentials with the following permissions:
  • s3:PutObject
  • s3:GetObject
  • s3:ListBucket

🛠️ Configuration

Initial Setup

s3docker config

Follow the interactive wizard to configure:

1. Profile name (e.g., 'prod', 'staging', 'default')
2. AWS Access Key ID
3. AWS Secret Access Key
4. AWS Region (default: us-east-1)
5. S3 Bucket name
6. S3 Path prefix (default: docker-images)

Managing Multiple Profiles

List all configured profiles:

s3docker configs

📚 Usage Guide

Pushing Images to S3

# Using default profile
s3docker push myapp:latest

# Using specific profile
s3docker push myapp:latest --to prod

# Replace existing image
s3docker push myapp:latest --replace

# Specify temporary directory
s3docker push myapp:latest --temp /path/to/temp
s3docker push myapp:latest --temp .  # Use current directory

Pulling Images from S3

# Using default profile
s3docker pull myapp:latest

# Using specific profile
s3docker pull myapp:latest --from prod

# Specify temporary directory
s3docker pull myapp:latest --temp /path/to/temp
s3docker pull myapp:latest --temp .  # Use current directory

Listing Available Images

# List images in default profile
s3docker list

# List images in specific profile
s3docker list --from prod

🔧 How It Works

1. Push Operation:

   • Saves Docker image to temporary tar file
   • If image exists in S3:
     • Moves existing image to archive folder (if --replace not used)
     • Archives include timestamps for version tracking
   • Uploads new image to S3
   • Cleans up temporary files

2. Pull Operation:

   • Downloads tar file from S3
   • Loads image into Docker
   • Automatically removes temporary files

3. Configuration Storage:

   • Configs stored in ~/.s3docker/configs.json
   • Separate profiles for different environments
   • Secure credential storage

🌟 Best Practices

1. Profile Management:

   • Use different profiles for development/staging/production
   • Keep production credentials separate
   • Regular credential rotation

2. Image Management:

   • Use specific tags instead of 'latest'
   • Utilize --replace flag carefully
   • Regular cleanup of archived versions
