Development Environment Setup Summary

What Was Configured

1. Development Docker Configuration

Dockerfile.dev - Enhanced development dockerfile

• Supports git branch selection via GIT_BRANCH build arg
• Includes podman and development tools
• Configured for rootless podman operation
• Copies source code for development access

docker-compose.dev.yml - Development compose file

• Branch selection via GIT_BRANCH environment variable
• Podman-in-podman support (privileged mode)
• Mounts:
  • Logs directory (persistent)
  • Data directory (database)
  • Source code (read-only)
  • Podman socket and storage
• Higher resource limits (4 CPU, 4GB RAM)
• Debug logging by default

2. Production Docker Configuration

docker-compose.yml - Updated for branch support

• Added GIT_BRANCH build argument
• Defaults to master branch for production
• Image tagged with branch name

3. Development Management Script

scripts/dev-env.sh - Comprehensive development tool

# Key commands:
./scripts/dev-env.sh start [branch]    # Start with branch
./scripts/dev-env.sh stop              # Stop environment
./scripts/dev-env.sh switch [branch]   # Switch branches
./scripts/dev-env.sh rebuild [branch]  # Rebuild from scratch
./scripts/dev-env.sh logs [-f]         # View logs
./scripts/dev-env.sh shell             # Access container
./scripts/dev-env.sh status            # Check status
./scripts/dev-env.sh branches          # List branches
./scripts/dev-env.sh clean             # Clean everything

4. Documentation

DEV_ENVIRONMENT.md - Complete development guide

• Quick start instructions
• Branch switching workflow
• Debugging guidelines
• Comparison with production setup
• Troubleshooting tips

Key Features

Branch Selection

Develop on any git branch:

# Work on feature branch
./scripts/dev-env.sh start feat-new-feature

# Switch to fix branch
./scripts/dev-env.sh switch fix-critical-arbitrage-bugs

# Test on master
./scripts/dev-env.sh start master

Podman-in-Podman

Run podman commands inside the development container:

# Access container
./scripts/dev-env.sh shell

# Use podman inside
podman ps
podman images
podman run alpine echo "hello from nested podman"

Live Development

• Source code mounted at /app/source
• Logs persisted to ./logs
• Database persisted to ./data
• Configuration mounted from ./config/config.dev.yaml

Usage Examples

Feature Development Workflow

# 1. Create and checkout feature branch
git checkout -b feat-my-feature master-dev

# 2. Start development environment
./scripts/dev-env.sh start feat-my-feature

# 3. Make code changes
vim pkg/arbitrage/service.go

# 4. Rebuild to test
./scripts/dev-env.sh rebuild feat-my-feature

# 5. View logs
./scripts/dev-env.sh logs -f

# 6. Debug if needed
./scripts/dev-env.sh shell

# 7. Stop when done
./scripts/dev-env.sh stop

# 8. Commit changes
git add .
git commit -m "feat: implement new feature"

Testing Multiple Branches

# Test master-dev
./scripts/dev-env.sh switch master-dev
# ... verify functionality ...

# Test fix branch
./scripts/dev-env.sh switch fix-critical-arbitrage-bugs
# ... verify fix works ...

# Test feature branch
./scripts/dev-env.sh switch feat-podman-compose-support
# ... verify feature works ...

Debugging Production Issues

# Reproduce on production branch
./scripts/dev-env.sh start master

# Check logs for errors
./scripts/dev-env.sh logs -f | grep ERROR

# Access container for inspection
./scripts/dev-env.sh shell

# Inside container:
cat /app/config/config.yaml
ls -la /app/logs
ps aux

Environment Variables

Configure via .env file or export:

# Branch to use
export GIT_BRANCH=master-dev

# Logging
export LOG_LEVEL=debug

# Metrics
export METRICS_ENABLED=true
export METRICS_PORT=9090

# RPC
export ARBITRUM_RPC_ENDPOINT=https://arb1.arbitrum.io/rpc
export ARBITRUM_WS_ENDPOINT=

# Bot config
export MEV_BOT_ENCRYPTION_KEY=your_key_here

Container Naming

Development containers are named based on branch:

• master-dev → mev-bot-dev-master-dev
• fix-critical-arbitrage-bugs → mev-bot-dev-fix-critical-arbitrage-bugs
• feat-new-feature → mev-bot-dev-feat-new-feature

This allows multiple branch containers (though not recommended to run simultaneously).

Differences from Production

Aspect	Development	Production
Dockerfile	Dockerfile.dev	Dockerfile
Compose File	docker-compose.dev.yml	docker-compose.yml
Container Name	mev-bot-dev-{branch}	mev-bot-production
Default Branch	master-dev	master
Privileged Mode	Yes	No
Podman-in-Podman	Yes	No
Source Mounted	Yes	No
CPU Limit	4 cores	2 cores
Memory Limit	4GB	2GB
Restart Policy	unless-stopped	always
Auto-start on Boot	No	Yes (systemd)
Log Level	debug	info

Next Steps

1. Test the setup:

   ./scripts/dev-env.sh start master-dev
   ./scripts/dev-env.sh status
   ./scripts/dev-env.sh logs -f
   

2. Create feature branch:

   git checkout -b feat-my-new-feature master-dev
   ./scripts/dev-env.sh start feat-my-new-feature
   

3. Develop and test:

   • Make code changes
   • Rebuild with ./scripts/dev-env.sh rebuild
   • Test functionality
   • Debug with ./scripts/dev-env.sh shell

4. Merge when ready:

   ./scripts/dev-env.sh stop
   git checkout master-dev
   git merge feat-my-new-feature
   git push origin master-dev
   

Troubleshooting

See DEV_ENVIRONMENT.md for detailed troubleshooting steps.

Common issues:

• Build failures → Check Dockerfile.dev syntax
• Container won't start → Check logs with ./scripts/dev-env.sh logs
• Podman socket errors → Ensure podman service is running
• Out of disk space → Run ./scripts/dev-env.sh clean
