Explore available plugins - -```bash -# List all available plugins -a6 plugin list - -# Get the schema for a specific plugin -a6 plugin get key-auth --output json -a6 plugin get limit-count --output json -``` - -## Building Your First API - -### Step 1: Create an upstream (your backend) - -```bash -a6 upstream create -f - <<'EOF' -{ - "id": "my-api-backend", - "type": "roundrobin", - "nodes": { - "localhost:3000": 1 - } -} -EOF -``` - -### Step 2: Create a route - -```bash -a6 route create -f - <<'EOF' -{ - "id": "my-api", - "uri": "/api/*", - "methods": ["GET", "POST", "PUT", "DELETE"], - "upstream_id": "my-api-backend" -} -EOF -``` - -### Step 3: Test it - -```bash -curl http://localhost:9080/api/hello -``` - -### Step 4: Add authentication - -```bash -# Create a consumer with key-auth -a6 consumer create -f - <<'EOF' -{ - "username": "dev-user", -

-## Plugin Selection Guide - -Use this decision tree to choose the right plugins for your API. - -### Authentication — "Who is calling?" - -| Need | Plugin | Key Feature | -|------|--------|-------------| -| Simple API key | `key-auth` | Header/query param key lookup | -| JWT tokens | `jwt-auth` | RS256/HS256, token in header/query/cookie | -| Username/password | `basic-auth` | HTTP Basic authentication | -| HMAC signatures | `hmac-auth` | Request body signing, replay prevention | -| OAuth2/OIDC | `openid-connect` | Auth0, Okta, Keycloak integration | - -### Rate Limiting — "How much can they call?" - -| Need | Plugin | Key Feature | -|------|--------|-------------| -| Fixed window counter | `limit-count` | N requests per time window, Redis cluster support | -| Leaky bucket | `limit-req` | Smooth rate limiting, burst allowance | - -### Transformation — "Change request/response" - -| Need | Plugin | Key Feature | -|------|--------|-------------| -| Rewrite URI/headers | `proxy-rewrite` | Strip prefixes, add headers, change host | -| Modify response | `response-rewrite` | Change status code, body, headers | -| A/B testing, canary | `traffic-split` | Weighted routing, conditional matching | -| URL redirect | `redirect` | HTTP 301/302/307 redirects | - -### Security — "Block bad traffic" - -| Need | Plugin | Key Feature | -|------|--------|-------------| -| IP whitelist/blacklist | `ip-restriction` | CIDR support, allow/deny lists | -| CORS headers | `cors` | Cross-origin resource sharing | -| Access control | `consumer-restriction` | Restrict by consumer, group, or route | - -### Observability — "What's happening?" - -| Need | Plugin | Key Feature | -|------|--------|-------------| -| Metrics | `prometheus` | Latency, status codes, bandwidth | -| Distributed tracing | `zipkin` or `skywalking` | Request trace correlation | -| Access logs | `http-logger` or `kafka-logger` | Structured log export | - -## Common Patterns - -### API with auth + rate limiting - -```bash -a6 route create -f - <<'EOF' -{ - "uri": "/api/*", - "upstream_id": "my-api-backend", - "plugins": { - "key-auth": {}, - "limit-count": { -

"uri": "/v1/*", - "upstream_id": "my-api-backend", - "plugins": { - "proxy-rewrite": { - "regex_uri": ["^/v1/(.*)", "/$1"] - } - } -} -EOF -``` - -### Add CORS for frontend apps - -```bash -a6 route update my-api -f -

Verify access - -```bash -# From allowed IP (e.g., 10.0.1.5) → 200 OK -curl -i http://127.0.0.1:9080/admin/dashboard - -# From blocked IP → 403 Forbidden -# {"message": "Your IP address is not allowed"} -``` - -## Step-by-Step: Blacklist Specific IPs - -```bash -a6 route create -f - <<'EOF' -{ - "id": "public-api", - "uri": "/api/*", - "plugins": { - "ip-restriction": { - "blacklist": [ - "203.0.113.0/24", - "198.51.100.42" - ], - "message": "Access denied from your network", - "response_code": 403 - } - }, - "upstream": { - "type": "roundrobin", - "nodes": { - "backend:8080": 1 - } - } -} -EOF -``` - -## Common Patterns - -### Real client IP behind a proxy (X-Forwarded-For) - -By default, `ip-restriction` uses `$remote_addr` which is the direct client -(often a load balancer). To use the real client IP, combine with the `real-ip` -plugin: - -```json -{ - "plugins": { - "real-ip": { - "source": "http_x_forwarded_for", - "trusted_addresses": ["10.0.0.0/8"] - }, - "ip-restriction": { - "whitelist": ["203.0.113.0/24"] - } - } -} -``` - -**Critical**: Always set `trusted_addresses` in `real-ip` to prevent IP -spoofing. Only accept `X-Forwarded-For` from known proxy IPs. - -### Custom 404 response (hide endpoint existence) - -```json -{ - "plugins": { - "ip-restriction": { - "blacklist": ["0.0.0.0/0"], - "whitelist": ["10.0.0.0/8"], - "response_code": 404, - "message": "Not found" - } - } -} -``` - -> Note: You cannot actually use both whitelist and blacklist.

Flow - -1. User visits `http://127.0.0.1:9080/app/dashboard` → no session -2. APISIX redirects to Keycloak login page -3.

Each group supplies shared plugin -configuration, such as rate limits and transformations, to its consumers. - -### 1. Create consumer groups for tenant policy sets - -```bash -# Free tier — 100 requests/day per consumer -a6 consumer-group create -f - <<'EOF' -{ - "id": "tenant-free", - "desc": "Free tier tenant", - "plugins": { - "limit-count": { - "count": 100, - "time_window": 86400, - "key_type": "var", - "key": "consumer_name", - "rejected_code": 429, - "rejected_msg": "Free tier quota exceeded" - } - } -} -EOF - -# Pro tier — 10000 requests/day per consumer -a6 consumer-group create -f - <<'EOF' -{ - "id": "tenant-pro", - "desc": "Pro tier tenant", - "plugins": { - "limit-count": { - "count": 10000, - "time_window": 86400, - "key_type": "var", - "key": "consumer_name", - "rejected_code": 429, - "rejected_msg": "Pro tier quota exceeded" - } - } -} -EOF -``` - -### 2.
