Get Started

Install and run the Flexprice Bento Collector with Docker or Kubernetes

Get the Flexprice Bento Collector running in minutes.

Prerequisites

• Flexprice API key
• Event source (Kafka, webhooks, database)

Quick Start with Docker

1. Create config.yaml:

input:
  kafka:
    addresses: [${KAFKA_BROKERS}]
    topics: [usage-events]
    consumer_group: flexprice-collector

pipeline:
  processors:
    - mapping: |
        root.event_name = this.event_name
        root.external_customer_id = this.customer_id
        root.properties = this.properties.map_each(p -> p.value.string())
        root.timestamp = this.timestamp.or(now().format_timestamp("2006-01-02T15:04:05Z07:00"))

output:
  flexprice:
    api_host: https://api.flexprice.io
    api_key: ${FLEXPRICE_API_KEY}
    scheme: https
    batching:
      count: 10
      period: 2s

2. Run with Docker:

docker run -d \
  --name bento-collector \
  -e FLEXPRICE_API_KEY=fp_live_xxxxx \
  -e KAFKA_BROKERS=broker:9092 \
  -v $(pwd)/config.yaml:/bento.yaml:ro \
  ghcr.io/flexprice/bento-collector:latest \
  -c /bento.yaml

3. Check logs:

docker logs -f bento-collector

# Expected:
# INFO Flexprice output connected and ready
# INFO Input type kafka is now active

Kubernetes Deployment

1. Create Secret:

kubectl create secret generic bento-collector \
  --from-literal=FLEXPRICE_API_KEY=fp_live_xxxxx \
  --from-literal=KAFKA_BROKERS=broker:9092

2. Deploy:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: bento-collector
spec:
  replicas: 2
  selector:
    matchLabels:
      app: bento-collector
  template:
    metadata:
      labels:
        app: bento-collector
    spec:
      containers:
      - name: bento
        image: ghcr.io/flexprice/bento-collector:latest
        args: ["-c", "/config/config.yaml"]
        envFrom:
        - secretRef:
            name: bento-collector
        resources:
          requests:
            memory: "256Mi"
            cpu: "250m"

Configuration

Batching

Tune based on event volume:

output:
  flexprice:
    batching:
      count: 10      # Events per batch
      period: 2s     # Max wait time
    max_in_flight: 10  # Concurrent requests

Guidelines:

• Low volume (< 100/min): count: 5, period: 5s
• Medium volume: count: 10, period: 2s (default)
• High volume (> 1000/min): count: 50, period: 1s

Kafka Performance

input:
  kafka:
    fetch_buffer_cap: 256        # Fetch more messages for batching
    commit_period: 1s
    max_processing_period: 100ms

Troubleshooting

Events not batching?

• Increase fetch_buffer_cap in Kafka input
• Check event volume is sufficient
• Rebuild binary if code changed

Connection errors?

• Verify API key is correct
• Check Kafka broker addresses
• Ensure external_customer_id exists in Flexprice

Memory issues?

• Reduce fetch_buffer_cap
• Lower max_in_flight
• Set resource limits

Environment Variables

Variable	Description	Example
FLEXPRICE_API_KEY	Flexprice API key	fp_live_abc123...
FLEXPRICE_API_HOST	API hostname	https://api.flexprice.io
KAFKA_BROKERS	Kafka brokers	broker:9092

Observability

The collector exposes Prometheus metrics at /metrics:

metrics:
  prometheus:
    enabled: true
    prefix: bento

http:
  enabled: true
  address: 0.0.0.0:4195

Access metrics: http://localhost:4195/metrics
