storm-docker
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
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.
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.
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
