Riak Mesos Director

The Riak Mesos Director is part of the Apache Mesos framework for Riak KV, a distributed NoSQL key-value data store that offers high availability, fault tolerance, operational simplicity, and scalability.

This repository is installed as part of the Mesos Framework, which is available here. There is no reason to build this project unless you would like to contribute to it.

Note: This project is an early proof of concept. The code is in beta release and there may be bugs, incomplete features, incorrect documentation or other discrepancies.

Admin CLI

./rel/riak_mesos_director/bin/director start

Test

In addition to the CLI, there are similar web endpoints:

• GET /status
• PUT /configure/frameworks/{framework}/clusters/{cluster}
  • Change the framework and cluster to proxy on the fly
• GET /frameworks
• GET /clusters
• GET /nodes

curl 'http://localhost:9000/nodes'

Should return:

{
    "nodes": [
        {
            "http": {
                "host": "ubuntu.local",
                "port": 31415
            },
            "name": "mycluster-32c28cff-5f9f-475c-9a3b-4b0bd4e51829-66@ubuntu.local",
            "protobuf": {
                "host": "ubuntu.local",
                "port": 31416
            }
        }
    ]
}

Local port 8098 should now proxy to the pool of available nodes

curl 'http://localhost:8098/ping'

Should return:

OK
