Cassandra 2.1.5 as a Docker container. For development use only.

Quickstart

TL;DR

Paste this into your terminal to start a 5 node cluster with OpsCenter:

bash <(curl -sL http://bit.ly/docker-cassandra)

OR, if you don't trust the one-liner, here are its contents:

#!/bin/bash
docker pull abh1nav/opscenter:latest
docker pull abh1nav/cassandra:latest
echo "Starting OpsCenter"
docker run -d --name opscenter abh1nav/opscenter:latest
sleep 10
OPS_IP=$(docker inspect -f '{{ .NetworkSettings.IPAddress }}' opscenter)
echo "Starting node cass1"
docker run -d --name cass1 -e OPS_IP=$OPS_IP abh1nav/cassandra:latest
sleep 30
SEED_IP=$(docker inspect -f '{{ .NetworkSettings.IPAddress }}' cass1)
for name in cass{2..5}; do
  echo "Starting node $name"
  docker run -d --name $name -e SEED=$SEED_IP -e OPS_IP=$OPS_IP abh1nav/cassandra:latest
  sleep 30
done
echo "Registering cluster with OpsCenter"
curl \
  http://$OPS_IP:8888/cluster-configs \
  -X POST \
  -d \
  "{
      \"cassandra\": {
        \"seed_hosts\": \"$SEED_IP\"
      },
      \"cassandra_metrics\": {},
      \"jmx\": {
        \"port\": \"7199\"
      }
  }" > /dev/null
echo "Go to http://$OPS_IP:8888/"

Manual Mode

OpsCenter

Skip this section if you don't want to run OpsCenter.

Pull the image and launch OpsCenter.

docker pull abh1nav/cassandra:latest
docker run -d --name opscenter abh1nav/opscenter:latest

Grab the OpsCenter IP:

OPS_IP=$(docker inspect -f '{{ .NetworkSettings.IPAddress }}' opscenter)

Single Node

Pull the image.

docker pull abh1nav/cassandra:latest

Launch the node

• without OpsCenter:

docker run -d --name cass1 abh1nav/cassandra:latest

• with OpsCenter:

docker run -d --name cass1 -e OPS_IP=$OPS_IP abh1nav/cassandra:latest

Grab the seed node's IP using:

SEED_IP=$(docker inspect -f '{{ .NetworkSettings.IPAddress }}' cass1)

Connect to it using CQLSH:

cqlsh $SEED_IP

Multiple Nodes

Follow the single node setup to get the first node running and keep track of its IP. Run the following to launch the other nodes in the cluster:

• without OpsCenter:

for name in cass{2..5}; do
  echo "Starting node $name"
  docker run -d --name $name -e SEED=$SEED_IP abh1nav/cassandra:latest
  sleep 30
done

• with OpsCenter:

for name in cass{2..5}; do
  echo "Starting node $name"
  docker run -d --name $name -e SEED=$SEED_IP -e OPS_IP=$OPS_IP abh1nav/cassandra:latest
  sleep 30
done

Once all the nodes are up, check cluster status using:

nodetool --host $SEED_IP status

or, if you installed OpsCenter, go to http://$OPS_IP:8888 and choose the "Add Existing Cluster option".
