Aiven

Get started with Lenses. Set it up with Docker and connect to an Aiven-managed Kafka with the standard configuration.

1. Get your Lenses access key

Aiven for Apache Kafka is a fully managed streaming platform, deployable in the cloud of your choice.

Start by signing up for an Aiven account . Follow the in-product instructions to launch Kafka clusters within the Aiven user interface.

Then, enable the additional Kafka features to get the most of it.

Enable Schema Registry

Enable Kafka Connect

Add Jolokia integration to enable JMX Metrics

Gather 4 connection points

Kafka endpoint

Schema Registry endpoint

Kafka Connect endpoint

Jolokia endpoint

Download 3 Aiven certificates

3. Get Docker

You will use docker-compose to spin up Lenses.

Start by signing up with Docker . Then install docker-compose .

4. Setup Lenses docker-compose

Use this docker-compose.yml file to spin up Lenses and connect to your Aiven Kafka.

Just 2 steps:

Fill in the connection details:
1. Kafka endpoint
2. Schema Registry
3. Kafka Connect
4. Jolokia endpoint
Share the authentication files with your docker. Copy these files in the same directory as your docker-compose.yml file and reference them:
1. Your Lenses license key license.json
2. The 3 Aiven certificate files

The file:

version: '3'
services:
  lenses:
    image: lensesio/lenses
    environment:
      # Admin user credentials
      LENSES_SECURITY_USER: admin
      LENSES_SECURITY_PASSWORD: admin
      LENSES_PORT: 80
      
      # === Set your values in this section ===
      
      # ===Step 1=== Put your Aiven Kafka 'Service URI' here
      # e.g. 
      # LENSES_KAFKA_BROKERS: SSL://lenses-aiven-kafka-lenses-56f3.aivencloud.com:23381
      # Kafka Endpoint
      LENSES_KAFKA_BROKERS: SSL://[AIVEN_HOST]:[AIVEN_PORT]
      # Aiven SSL configuration
      LENSES_KAFKA_SETTINGS_CLIENT_SECURITY_PROTOCOL: SSL
      
      # ===Step 2=== Put the Aiven Schema Registry endpoint here
      # Aiven Schema Registry (Karapace)
      LENSES_SCHEMA_REGISTRY_URLS: '[{url: "https://[REGISTRY_HOST]:[REGISTRY_PORT]"}]'
      LENSES_SCHEMA_REGISTRY_AUTH: USER_INFO
      LENSES_SCHEMA_REGISTRY_USERNAME: [USER]
      LENSES_SCHEMA_REGISTRY_PASSWORD: [PASSWORD]
      LENSES_KAFKA_SETTINGS_CLIENT_BASIC_AUTH_CREDENTIALS_SOURCE: USER_INFO
      LENSES_KAFKA_SETTINGS_CLIENT_BASIC_AUTH_USER_INFO: [USER]:[PASSWORD]

      # ===Step 3=== Put the Kafka Connect endpoint here
      # Kafka Connect
      LENSES_CONNECT_CLUSTERS: |
        [{
          name:"aiven_connect",
          urls: [{url:"https://[CONNECT_HOST]:[CONNECT_PORT]"}],
          auth = "USER_INFO",
          username = "[USER]",
          password = "[PASSWORD]",
          statuses:"__connect_status",
          configs:"__connect_configs",
          offsets:"__connect_offsets"
        }]

      # ===Step 4=== Put your Aiven Jolokia REST endpoint here
      # Kafka JMX metrics with Aiven Jolokia
      LENSES_KAFKA_METRICS: |
        {
          type: "JOLOKIAP",
          default.port: "[CLIENT_PORT]"
          user: "[BASIC_AUTH_USERNAME]",
          password: "[BASIC_AUTH_PASSWORD]",
          ssl: true
        }
      
    ports:
      - 80:80
    volumes:
      # ===Step 5=== Share your authentication files here
      # Map the Lenses license key file here to activate Lenses
      - ./license.json:/license.json
      # Map the Aiven files here to enable Lenses to communicate with Aiven via SSL
      - ./service.key:/mnt/secrets/FILECONTENT_SSL_KEY_PEM
      - ./service.cert:/mnt/secrets/FILECONTENT_SSL_CERT_PEM
      - ./ca.pem:/mnt/secrets/FILECONTENT_SSL_CACERT_PEM

4. Start Lenses up

docker-compose up

User:     admin
Password: admin
