Message router

Microservice for dispatching messages received by HTTP (JSON RPC v2) to Apache Kafka.

How to use

Docker

Pull and run docker image. Don't forget to set Apache Kafka brokers host by MESSAGE_ROUTER_KAFKA_BROKERS environment variable.

docker pull strider2038/message-router
docker run --name message-router -d -p 3000:3000 -e "MESSAGE_ROUTER_KAFKA_BROKERS: http://kafka.com:9092" strider2038/message-router

Now you can send messages that will be dispatched to Apache Kafka.

POST http://localhost:3000/rpc
Content-Type: application/json

[
    {
        "jsonrpc": "2.0",
        "method": "dispatch",
        "params": {
            "topic": "firstTopic",
            "message": {
                "value": {
                    "property": "value",
                    "object": {
                        "a": 1
                    }
                }
            }
        },
        "id": 1
    },
    {
        "jsonrpc": "2.0",
        "method": "dispatch",
        "params": {
            "topic": "secondTopic",
            "message": {
                "value": {
                    "body": "Message body"
                }
            }
        },
        "id": 2
    }
]
