[cassandra] docker + cassandra

분산시스템 구성을 위해 docker위에 cassandra를 셋팅하는 법에 대해서 알아보자. 

 

 

1. docker에 cassandra download

docker pull cassandra:latest

 

2. 노드 0번 (seed node) 실행 

docker run --name cassandra-node-0 --p 7000:7000 -p 7001:7001 -p 9042:9042 -p 9160:9160 -e CASSANDRA_CLUSTER_NAME=MyCluster -e CASSANDRA_ENDPOINT_SNITCH=GossipingPropertyFileSnitch -e CASSANDRA_DC=datacenter1 -d cassandra

 

3. seed 노드에 할당된 ip 확인

>docker inspect --format='{{ .NetworkSettings.IPAddress}}' cassandra-node-0

 

4. 노드 1번 실행

docker run --name cassandra-node-1 -p 17000:7000 -p 17001:7001 -p 19042:9042 -p 19160:9160 -e CASSANDRA_SEEDS="$(docker inspect --format='{{ .NetworkSettings.IPAddress}}' cassandra-node-0)" -e CASSANDRA_CLUSTER_NAME=MyCluster -e CASSANDRA_ENDPOINT_SNITCH=GossipingPropertyFileSnitch -e CASSANDRA_DC=datacenter1 -d cassandra

 

5. 노드 2번 실행

docker run --name equal-a-cassandra-node-2 -p 27000:7000 -p 27001:7001 -p 29042:9042 -p 29160:9160 -e CASSANDRA_SEEDS="$(docker inspect --format='{{ .NetworkSettings.IPAddress}}' cassandra-node-0)" -e CASSANDRA_CLUSTER_NAME=MyCluster -e CASSANDRA_ENDPOINT_SNITCH=GossipingPropertyFileSnitch -e CASSANDRA_DC=datacenter1 -d cassandra

  

6. 확인

 

- cql 실행

docker run -it -e CQLSH_HOST=$(docker inspect --format='{{ .NetworkSettings.IPAddress}}' cassandra-node-0) --name cassandra-client --entrypoint=cqlsh cassandra

- nodetool status 실행

docker exec -ti equal-a-cassandra-node-1 nodetool status
