Click "Install on all nodes" and then "Accept Fingerprints".   |   Launch a container running Cassandra called cassone: docker run --detach --name cassone poklet/cassandra Connect to it using cqlsh We use --link cass1:seed to name the cass1 host as our seed host. These images are great to provision ephemeral Cassandra topologies for testing and development purpose. Launch a terminal window, run “docker pull cassandra” command to fetch the latest official cassandra image. We can find the ip address of cas1 by running the following command: I’ll add it to docker run command strings for cas2 and cas3: Notice that I gave a different datacenter name (datacenter2) while creating the cas3 node. Apache Cassandra: Begins with Docker. Forums, © The first thing we want to do is create an overlay network for our cluster to use. Now Let’s create a keyspace (database) which will be replicated to datacenter1 and datacenter2, and a table in this newly created keyspace. A multi-node cluster - running on a single Docker host, Click on the "Use Existing Cluster" button and put at least the IP of one node in the cluster in the host text box. Quickstart. Did you notice that the nodes at datacenter1 shares data almost evenly, while the node at datacenter2 has replication of all data? A boot2docker image containing the experimental version is used.

Here's how to start a Cassandra cluster with a single node, and run some CQL on it. To make it simpler, we’ll place both containers within the same node (local machine) docker run --name my-cassandra-1 --network cassandra-net -d -e CASSANDRA_SEEDS=my-cassandra cassandra:latest Extra Steps. First of all, we need to assign about 5 GB RAM to Docker (in case it has less RAM assigned), because each node will require 1.5+ GB RAM to work properly. I’ll use official cassandra images instead of creating my own images, so all process will take only a few minutes (depending on your network connection). I am using thingsboard (on docker) but I want also able to connect to the cassandra on thingboard docker. The nodetool-ssl Docker Compose service can be used to check on the Cassandra node’s status: docker-compose run nodetool-ssl status Once the Cassandra node is online and accepting encrypted SSL connections via the Native Transport protocol, create the required reaper_db Cassandra keyspace to allow Reaper to save its cluster and scheduling data.

Remember the replication strategy of our keyspace: Each datacenter stores one copy. I tried to find a stable GUI for Cassandra, and DevCenter looks fine to me: After we created the keyspace, we can use “nodetool status” to check its distribution: As you can see, I gave the name of the keyspace as a parameter to nodetool, so it will show the distribution of our newly created keyspace. The guide is intended for development, and not for a production deployment. Use it for your tests! Create Docker Account. node1), we will be in the Cassandra node.

Gokhan is a founding member and current vice president of Turkish Oracle User Group (TROUG). Because there are two nodes in datacenter1, the data will be evenly distributed between these two nodes. Here’s the CQL (cassandra query language) commands to create the keyspace and table: We can execute these commands using cqlsh by connecting one of our nodes: Or we can execute them using a client program such as DevCenter (you need to register to DataStax website to be able to download it). Informationabout building it can be found here. Gokhan specializes in high availability solutions, performance tuning and monitoring tools. 3 node cassandra cluster with docker-compose Raw.
