flaviof / docker-hazelcast-mapstore-cassandra

A docker multinode hazelcast running with a Cassandra map store

docker-hazelcast-map-store-cassandra

This project creates a docker image to run Hazelcast with a Cassandra map store.

Pre-requisites

• JDK 8
• Maven 3.1.0 or newer
• Cassandra 2.1.2
• Docker 1.5

Build

Clone

git clone https://github.com/FlavioF/docker-hazelcast-map-store-cassandra.git
cd docker-hazelcast-map-store-cassandra

Build Docker image

./rebuild.sh

Running Hazelcast Node

./start-hazelcast.sh

or

docker run -d -p 5701:5701 --name hazelcast1 -e "GROUP_NAME=test-group" -e "CASSANDRA_HOST=172.17.42.1" -e "GROUP_PASS=test" fferreira/hazelcast

Running Multi Nodes of Hazelcast

./start-hazelcast-multi-nodes.sh

You can use docker logs to see if everything is ok.

Run this:

docker logs hazelcast1

You should expect something like this:
