Cloudflare Management

Comprehensive Cloudflare service management using Wrangler CLI (primary tool) and REST API (for advanced/non-Wrangler services).

Tool Selection

| Service | Primary Tool | Alternative | |---------|--------------|-------------| | Workers, Pages, KV, R2, D1, Queues, AI, Vectorize, Hyperdrive | Wrangler CLI | - | | DNS, SSL/TLS, Zones, Load Balancers | REST API scripts | Terraform | | WAF, Rate Limiting, Firewall Rules, Bot Management | REST API scripts | Terraform | | Zero Trust, Access, Tunnels | cloudflared CLI + REST API | - | | Analytics, Logs | GraphQL API + REST API | Dashboard |

Decision Flow:

Developer Platform (Workers/Pages/Storage) → Use Wrangler
DNS/Zone/SSL → Use cf-zone-management.sh script
Security (WAF/Firewall) → Use cf-security.sh script
Custom/Advanced → Use cf-api.sh script with REST API

Quick Start

1. Install Wrangler

# Check if installed
which wrangler

# If not installed (or outdated)
npm install -g wrangler@latest

# Verify
wrangler --version

2. Authenticate

Interactive (recommended for local dev):

wrangler login
# Opens browser for OAuth

API Token (recommended for CI/CD):

# Set environment variables (see references/authentication.md for token creation)
export CLOUDFLARE_API_TOKEN="your_token_here"
export CLOUDFLARE_ACCOUNT_ID="your_account_id"

# Verify
wrangler whoami

3. Common Workflows

Deploy a Worker:

# Create new project
npm create cloudflare@latest my-worker

# Or deploy existing
cd my-worker
wrangler deploy

Manage KV Storage:

# Create namespace
wrangler kv namespace create MY_KV

# Add to wrangler.toml, then:
wrangler kv key put --namespace-id=<id> "mykey" "myvalue"
wrangler kv key get --namespace-id=<id> "mykey"

Deploy to Pages:

wrangler pages deploy ./dist

R2 Bucket Operations:

# Create bucket
wrangler r2 bucket create my-bucket

# Upload object
wrangler r2 object put my-bucket/path/file.txt --file=./local-file.txt

# List objects
wrangler r2 object list my-bucket

D1 Database:

# Create database
wrangler d1 create my-database

# Run migrations
wrangler d1 migrations apply my-database

# Execute SQL
wrangler d1 execute my-database --command="SELECT * FROM users"

Wrangler Core Commands

| Command | Purpose | Example | |---------|---------|---------| | wrangler init | Create new project | wrangler init my-project | | wrangler dev | Local development | wrangler dev | | wrangler deploy | Deploy to production | wrangler deploy | | wrangler tail | Stream logs | wrangler tail my-worker | | wrangler secret put | Add secret | wrangler secret put API_KEY | | wrangler publish | Legacy deploy (use deploy) | - | | wrangler whoami | Check auth | wrangler whoami |

For complete command reference, see references/wrangler-commands.md.

REST API Access (Non-Wrangler Services)

For services not covered by Wrangler (DNS, SSL, WAF, etc.), use the provided scripts:

Zone Management

# List all zones
bash scripts/cf-zone-management.sh zones list

# Create a new zone
bash scripts/cf-zone-management.sh zones create example.com

# Delete a zone
bash scripts/cf-zone-management.sh zones delete example.com

# Get zone details
bash scripts/cf-zone-management.sh zone get example.com

# Get all zone settings
bash scripts/cf-zone-management.sh zone settings example.com

# Purge zone cache
bash scripts/cf-zone-management.sh zone purge-cache example.com

DNS Management

# List DNS records
bash scripts/cf-zone-management.sh dns list example.com

# Create A record
bash scripts/cf-zone-management.sh dns create example.com A "api" "192.0.2.1"

# Update record
bash scripts/cf-zone-management.sh dns update example.com <record-id> A "api" "192.0.2.2"

# Delete record
bash scripts/cf-zone-management.sh dns delete example.com <record-id>

SSL Certificate Management

# List certificates
bash scripts/cf-zone-management.sh ssl list example.com

# Get SSL settings
bash scripts/cf-zone-management.sh ssl settings example.com

# Update SSL mode (off, flexible, full, strict)
bash scripts/cf-zone-management.sh ssl update example.com strict

Security Rules

# List firewall rules
bash scripts/cf-security.sh firewall list example.com

# Create rate limit rule
bash scripts/cf-security.sh ratelimit create example.com "/api/*" 100

# List WAF rules
bash scripts/cf-security.sh waf list example.com

Generic API Calls

# GET request
bash scripts/cf-api.sh GET zones

# POST request with data
bash scripts/cf-api.sh POST zones/<zone-id>/dns_records '{"type":"A","name":"test","content":"192.0.2.1"}'

# PATCH request
bash scripts/cf-api.sh PATCH zones/<zone-id>/settings/ssl '{"value":"strict"}'

Configuration

wrangler.toml Structure

See assets/wrangler.toml.template for a comprehensive template.

Basic structure:

name = "my-worker"
main = "src/index.ts"
compatibility_date = "2024-01-01"

# KV namespaces
[[kv_namespaces]]
binding = "MY_KV"
id = "your_namespace_id"

# R2 buckets
[[r2_buckets]]
binding = "MY_BUCKET"
bucket_name = "my-bucket"

# D1 databases
[[d1_databases]]
binding = "DB"
database_name = "my-database"
database_id = "your_database_id"

# Environment variables
[vars]
ENVIRONMENT = "production"

# Routes
routes = [
  { pattern = "example.com/*", zone_name = "example.com" }
]

Environment Variables

Required for authentication (see references/authentication.md):

CLOUDFLARE_API_TOKEN=your_token_here
CLOUDFLARE_ACCOUNT_ID=your_account_id
CLOUDFLARE_ZONE_ID=your_zone_id  # For zone-specific operations

Common Patterns

Multi-Environment Deployment

# wrangler.toml
[env.staging]
name = "my-worker-staging"
vars = { ENVIRONMENT = "staging" }

[env.production]
name = "my-worker-production"
vars = { ENVIRONMENT = "production" }

# Deploy to staging
wrangler deploy --env staging

# Deploy to production
wrangler deploy --env production

Secret Management

# Add secret (interactive)
wrangler secret put API_KEY

# Add secret for specific environment
wrangler secret put API_KEY --env production

# List secrets (names only, values never exposed)
wrangler secret list

Local Development with Bindings

# wrangler.toml configured with KV/R2/D1 bindings

# Start local dev server (bindings available locally)
wrangler dev

# Access bindings in code:
# env.MY_KV.get("key")
# env.MY_BUCKET.get("file.txt")
# env.DB.prepare("SELECT * FROM users").all()

Remote Development (Wrangler v4+)

# Use REMOTE bindings instead of local stubs
wrangler dev --remote

# Useful for testing with production data

Service-Specific Guides

For detailed quick-start patterns for each service:

references/service-guides.md - Workers, Pages, R2, D1, KV, Queues, AI

For complete API surface coverage:

references/api-surface.md - All 14 API categories

Rate Limits & Quotas

Wrangler operations: Subject to account tier limits (Free/Pro/Business/Enterprise)

API operations:

Client API per user/account token: 1,200 requests per 5 minutes
Client API per IP: 200 requests per second
GraphQL: 320 requests per 5 minutes (variable by query cost)

Best practices:

Use Wrangler for bulk operations (built-in rate limit handling)
For direct API calls, implement exponential backoff on 429 responses
Cache API responses where appropriate (zone configs, etc.)

Troubleshooting

Common Issues

Authentication fails:

# Check token validity
wrangler whoami

# Re-authenticate
wrangler login

# Verify environment variables
echo $CLOUDFLARE_API_TOKEN
echo $CLOUDFLARE_ACCOUNT_ID

Deploy fails:

# Check syntax
wrangler deploy --dry-run

# View detailed logs
wrangler tail my-worker

# Check wrangler.toml syntax
wrangler config

KV/R2/D1 not accessible:

# Verify bindings in wrangler.toml
# Verify namespace/bucket/database exists
wrangler kv namespace list
wrangler r2 bucket list
wrangler d1 list

Script errors:

# Ensure CLOUDFLARE_API_TOKEN is set
export CLOUDFLARE_API_TOKEN="your_token"

# Ensure jq is installed (scripts use it for JSON parsing)
which jq || brew install jq  # or apt-get install jq

Migration from Legacy Tools

From `cf-cli` or `flarectl`

Both are deprecated. Migrate to:

Wrangler for Workers/Pages/Storage
REST API scripts (this skill) for DNS/SSL/Security
Terraform provider for infrastructure-as-code

From Cloudflare Dashboard

Export existing configs:

# DNS records
bash scripts/cf-zone-management.sh dns export example.com > dns-records.json

# Firewall rules
bash scripts/cf-security.sh firewall export example.com > firewall-rules.json
