Dockerfiles for building a storm cluster.
The images are available directly from https://index.docker.io
- install docker-compose https://docs.docker.com/compose/
Start a cluster:
Destroy a cluster:
Add more supervisors:
docker-compose scale supervisor=3
docker build -t vshlapakov/storm:0.9.4 .
How can I access Storm UI from my host?
Take a look at docker-compose.yml:
ui: image: vshlapakov/storm:0.9.4 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:
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 container id for the container you wish to connect to (use
$ docker exec -it CONTAINER_ID bash
