Docker build for DSE cassandra

There are three ways in which dse cassandra can be installed using this docker build.

• Copy dse.tar.gz from local folder

• Download dse.tar.gz from a host webserver

• Download dse.tar.gz from datastax download

Build dse cassandra using the Dockerfile

docker build -t skhatri/dse-cassandra .

To run an instance of dse cassandra

docker run -d -p 9160:9160 -t skhatri/dse-cassandra 

Set port forwarding for VirtualBox for environments using boot2docker

VBoxManage modifyvm "boot2docker-vm" --natpf1 "dse-node1,tcp,127.0.0.1,9260,,9160"

The above creates a port forwarding rule so that the host listens on 9260 forwarding to a docker instance running on port 9160

From the host system, you can invoke a cqlsh or use drivers to connect to cassandra using

cqlsh localhost 9260

More nodes can be run using the docker run command and the VBoxManage command to expose the service to the host system.

Running a multinode cluster using docker containers

• Start first node as seed

docker run -d -p 9160:9160 -p 9042:9042 -p 7199:7199 -t skhatri/cassandra

• Find the node with 9160 and treat it as seed and start another instance

docker run -d -p 9260:9160 -e SEEDS=$(docker inspect `docker ps -a |grep 9160\-\>9160|awk '{print $1}'`|grep 172|grep IP|awk '{print $2}'|cut -d',' -f1) -t skhatri/cassandra

• Start third instance of cassandra

docker run -d -e SEEDS=$(docker inspect `docker ps -a |grep 9160\-\>9160|awk '{print $1}'`|grep 172|grep IP|awk '{print $2}'|cut -d',' -f1) -t skhatri/cassandra
