Dockerfiles for building a storm cluster. Inspired by https://github.com/ptgoetz/storm-vagrant

The images are available directly from https://index.docker.io

##Pre-Requisites

• install docker-compose http://docs.docker.com/compose/install/

##Usage

Start a cluster:

• docker-compose up

Destroy a cluster:

• docker-compose stop

Add more supervisors:

• docker-compose scale supervisor=3

##Building

• rebuild.sh

##FAQ

How can I access Storm UI from my host?

Take a look at docker-compose.yml:

ui:
  image: wurstmeister/storm-ui:0.9.2
      ports:
        - "49080:8080"

This tells Docker to expose the Docker UI container's port 8080 as port 49080 on the host<br/>

If you are running docker natively you can use localhost. If you're using boot2docker, then do:

$ boot2docker ip
The VM's Host only interface IP address is: 192.168.59.103

Which returns your docker VM's IP.<br/> So, to open storm UI, type the following in your browser:

localhost:49080

or

192.168.59.103:49080

in my case.

How can I deploy a topology?

Since the nimbus host and port are not default, you need to specify where the nimbus host is, and what is the nimbus port number.<br/> Following the example above, after discovering the nimbus host IP (could be localhost, could be our docker VM ip as in the case of boot2docker), run the following command:

storm jar target/your-topology-fat-jar.jar com.your.package.AndTopology topology-name -c nimbus.host=192.168.59.103 -c nimbus.thrift.port=49627

How can I connect to one of the containers?

Find the forwarded ssh port for the container you wish to connect to (use docker-compose ps)

$ ssh root@`boot2docker ip` -p $CONTAINER_PORT
