A Dockerfile for deploying a Storm cluster under supervision using Docker containers.
The image is registered to the Docker Index
- Install Docker
- Pull the Docker image :
docker pull fhuz/docker-storm
Pre-Requisites: You must have a running zookeeper instance in order to start any of the storm daemons.
docker run -p 2181:2181 -p 2888:2888 -p 3888:3888 -h zookeeper --name="zookeeper" -d jplock/zookeeper;
The image contains an ENTRYPOINT for running one container per storm daemon as follow:
docker run [OPTIONS] --link zookeeper:zk -d fhuz/docker-storm --daemon (nimbus, drpc, supevisor, ui, logviewer)
For instance to run Nimbus :
docker run \
--name="storm-nimbus" -h nimbus \
--expose 6627 --expose 3772 --expose 3773 \
--link zookeeper:zk \
-d fhuz/docker-storm \
--daemon nimbus
You can override storm default configuration by passing environment variables to the running container as follows :
--env "CONFIG_WORKER_CHILDOPTS=-Xmx512m"
CONFIG_WORKER_CHILDOPTS will be add to storm.yaml as worker.childopts.
Pre-Requisites: Install Compose
Compose is a tool for defining and running complex applications with Docker.
-
To start cluster:
zookeeper:
docker-compose -p storm -f ./docker-zookeeper.yml up(pass the -d flag to run container in background)storm:
docker-compose -p storm -f ./docker-storm.yml up(pass the -d flag to run container in background) -
To stop cluster:
zookeeper:
docker-compose -p storm -f ./docker-zookeeper.yml stopstorm:
docker-compose -p storm -f ./docker-storm.yml stop
Or you can checkout this minimal Makefile for directly building and deploying storm.
To rebuild the fhuz/docker-storm image just run :
make storm-build
Run the following commands to deploy/destroy your cluster.
make deploy-clustermake destroy-cluster
Without storm installed on your machine:
docker run --rm --entrypoint storm \
-v <HOST_TOPOLOGY_TARGET_DIR>:/home/storm fhuz/docker-storm \
-c nimbus.host=`docker inspect --format='{{.NetworkSettings.IPAddress}}' storm-nimbus` jar <TOPOLOGY_JAR> <TOPOLOGY_ARGS>
Storm UI/Logviewer container ports are exposed to the host system :
- Storm UI : http://localhost:8080/
- Logviewer : http://localhost:8000/
If for some reasons you need to debug a container you can use docker exec command:
Example : docker exec -it storm_nimbus_1 /bin/bash
