Pipes: Deployment Documentation

Complete deployment infrastructure for Pipes indexers across local, cloud, and platform environments.

When to Use This Skill

Use this skill when you need to:

• Deploy an indexer to local Docker (development/testing)
• Deploy to ClickHouse Cloud (production data storage)
• Deploy to Railway platform (24/7 hosting)
• Understand deployment workflows and best practices
• Set up MCP servers for deployment monitoring
• Troubleshoot deployment issues
• Compare deployment options

Overview

This skill provides access to comprehensive deployment guides covering three deployment targets:

1. Local Deployment – Docker-based development environment
2. ClickHouse Cloud – Production data storage
3. Railway Platform – 24/7 managed hosting

Each deployment type has specialized documentation, automated workflows, and MCP integration.

Deployment Options Comparison

1. Local Deployment (Docker)

Purpose

Development and testing with local Docker-based ClickHouse.

Key Features

• Automatic Docker container detection/creation
• Auto-discovery of ClickHouse password
• Sync table conflict prevention
• 30-second data verification
• MCP auto-configuration

Quick Start

# Start ClickHouse container
docker run -d --name clickhouse \
  -p 8123:8123 -p 9000:9000 \
  -e CLICKHOUSE_PASSWORD=default \
  clickhouse/clickhouse-server

# Deploy indexer
cd my-indexer
bun run dev

# Verify data (after 30 seconds)
docker exec clickhouse clickhouse-client --password=default \
  --query "SELECT COUNT(*) FROM pipes.my_table"

When to Use

• Development workflow
• Quick iterations
• Testing before cloud deployment
• Learning the system

Documentation

• ClickHouse Cloud integration (required)
• Containerized deployment via Pipes CLI
• Pre-flight table validation
• Deployment monitoring
• Management command reference

Quick Start

Common Deployment Workflow

Pattern 1: Development to Production

# 1. Create indexer
/new-indexer my-protocol-indexer

# 2. Test locally with recent blocks
cd my-protocol-indexer
# Edit src/index.ts: range: { from: '20000000' }  # Recent
bun run dev

# 3. Verify data
docker exec clickhouse clickhouse-client \
  --query "SELECT * FROM pipes.events LIMIT 10"

# 4. Update to full history
# Edit src/index.ts: range: { from: '12345678' }  # Deployment block

# 5. Deploy to Cloud
CLICKHOUSE_URL=https://xxx.clickhouse.cloud:8443 bun run dev

# 6. Deploy to Railway (optional, for 24/7)
export RAILWAY_TOKEN=xxx
npx @iankressin/pipes-cli-test@latest deploy --provider railway

Pattern 2: Multiple Indexers (Isolated Databases)

# Indexer 1: Uniswap Base
DATABASE=uniswap_base bun run dev

# Indexer 2: Morpho Ethereum
DATABASE=morpho_ethereum bun run dev

# Benefits:
# - No sync table conflicts
# - Easy to drop/recreate individual indexers
# - Clear data organization

MCP Integration

ClickHouse MCP

Monitor and query data from deployed indexers.

// List databases
mcp__clickhouse__list_databases()

// List tables
mcp__clickhouse__list_tables({ database: "pipes" })

// Query data
mcp__clickhouse__run_select_query({
  query: "SELECT COUNT(*) FROM pipes.swaps"
})

// Analyze table
mcp__clickhouse__run_select_query({
  query: "DESCRIBE pipes.swaps"
})

Railway MCP

Manage Railway deployments.

// Check service status
mcp__railway__get_service(service_id)

// View logs
mcp__railway__stream_logs(service_id)

// Manage environment variables
mcp__railway__list_variables(service_id)
mcp__railway__set_variable(service_id, key, value)

// Deployment management
mcp__railway__list_deployments(service_id)
mcp__railway__restart_service(service_id)

Deployment Validation

Mandatory Checks (All Deployments)

After starting any indexer:

# 1. Check start block (within 30 seconds)
tail -f indexer.log
# Expected: "Start indexing from X" (your deployment block)
# Wrong: "Resuming from Y" (indicates sync table conflict)

# 2. Wait 30 seconds, check for data
# For local Docker:
docker exec clickhouse clickhouse-client --password=default \
  --query "SELECT COUNT(*) FROM pipes.my_table"

# For Cloud:
# Use ClickHouse Cloud Console or MCP

# 3. Verify data quality
docker exec clickhouse clickhouse-client --password=default \
  --query "SELECT * FROM pipes.my_table LIMIT 3 FORMAT Vertical"

# Check:
# - Addresses valid (0x... format)
# - Amounts reasonable
# - Timestamps correct
# - All fields populated

# 4. Wait another 30 seconds, verify increasing
# Count should be higher than step 2

Troubleshooting Common Issues

Issue 1: Wrong Start Block / Skipped Blocks

Symptom: Indexer starts from unexpected block (e.g., 27M instead of 21M)

Cause: Shared sync table with other indexers

Solution:

# Option A: Clear sync table before starting
docker exec clickhouse clickhouse-client --password=default \
  --query "TRUNCATE TABLE pipes.sync"

# Option B: Use separate database
CLICKHOUSE_DATABASE=my_unique_db bun run dev

Issue 2: ClickHouse Authentication Failed

Symptom: “Authentication failed” error

Solution:

# Get actual password from container
docker inspect clickhouse | grep CLICKHOUSE_PASSWORD

# Update .env with correct password
CLICKHOUSE_PASSWORD=actual_password

Issue 3: Railway Deployment Stuck

Symptom: Railway service won’t start or crashes immediately

Solution:

# Check logs for errors
railway logs

# Verify ClickHouse connection
# Must use ClickHouse Cloud (not local Docker)
CLICKHOUSE_URL=https://xxx.clickhouse.cloud:8443

# Check environment variables
railway variables

# Restart service
railway restart

Issue 4: Zero Data After Deployment

Symptom: Indexer syncing but database empty

Possible Causes:

• Wrong start block (after events occurred)
• Wrong contract address
• Proxy contract (need implementation ABI)
• Event name mismatch

Solution:

# Verify contract address is correct
# Check start block is before first event
# Verify ABI matches contract events
# Check for proxy contracts

Best Practices

1. Always Test Locally First

# DON'T: Deploy directly to Cloud/Railway
CLICKHOUSE_URL=https://xxx.clickhouse.cloud:8443 bun run dev

# DO: Test locally first
docker run -d --name clickhouse -p 8123:8123 \
  -e CLICKHOUSE_PASSWORD=default \
  clickhouse/clickhouse-server

bun run dev  # Test local first
# Then deploy to Cloud/Railway

2. Use Dedicated Databases

# DON'T: Share 'pipes' for everything
DATABASE=pipes  # For all indexers

# DO: Use unique databases
DATABASE=uniswap_base
DATABASE=morpho_ethereum
DATABASE=aave_polygon

3. Verify Start Block

# ALWAYS check first log line:
tail -f indexer.log | head -1

# Expected: "Start indexing from [your-block]"
# Wrong: "Resuming from [different-block]"

4. Monitor Data Quality

# After deployment:
# 1. Row count increasing ✓
# 2. No NULL values in critical fields ✓
# 3. Timestamps are recent ✓
# 4. Amounts are reasonable ✓
