Riak Mesos Framework Marathon JSON Generator
Full Description

Riak Mesos Framework Marathon JSON Generator

The Python script generate-json.py can be used as a stand-alone script or by running the Docker image built from the included Dockerfile. Upon invocation it will generate a Marathon JSON file appropriate for deploying the ingest or egress services to a given cluster. It assumes Mesos-DNS is running on the Mesos master on port 8123 and that a Kafka framework is deployed to the cluster that has at least one broker named broker-0.

Installing the script

If running the script outside a Docker container, first install the prerequisites by doing a pip install -r requirements.txt in this directory. If using the Docker container, you can either build the image locally and use a tag of your own choosing or run the default image from the Basho Docker Hub. You can then get help on running the utility by using the --help flag:

Non-Docker
$ python ./generate-json.py --help
Docker
$ docker run -i basho/generate-ingest-egress-json --help
