1. Install a Cassandra cluster using DC/OS CLI:

   Note: Your cluster must have at least 3 private nodes.

    $ dcos package install cassandra
   

2. Once the cluster is installed, retrieve connection information by running the connection command:

    $ dcos cassandra connection
    {
        "address": [
            "10.0.2.136:9042",
            "10.0.2.138:9042",
            "10.0.2.137:9042"
        ],
        "dns": [
             "node-0.cassandra.mesos:9042",
             "node-1.cassandra.mesos:9042",
             "node-2.cassandra.mesos:9042"
        ]
    
    }
   

3. SSH into a DC/OS node:

    $ dcos node ssh --master-proxy --leader
    core@ip-10-0-6-153 ~ $
   

   Now that you are inside your DC/OS cluster, you can connect to your Cassandra cluster directly.

4. Launch a docker container containing cqlsh to connect to your cassandra cluster:

    core@ip-10-0-6-153 ~ $ docker run -ti cassandra:3.0.7 cqlsh --cqlversion="3.4.0" node-0.cassandra.mesos
    cqlsh>
   

5. You are now connected to your Cassandra cluster. Create a sample keyspace called demo:

    cqlsh> CREATE KEYSPACE demo WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 3 };
   

6. Create a sample table called map in our demo keyspace:

    cqlsh> USE demo;CREATE TABLE map (key varchar, value varchar, PRIMARY KEY(key));
   

7. Insert some data in the table:

    cqlsh> INSERT INTO demo.map(key, value) VALUES('Cassandra', 'Rocks!');
    cqlsh> INSERT INTO demo.map(key, value) VALUES('StaticInfrastructure', 'BeGone!');
    cqlsh> INSERT INTO demo.map(key, value) VALUES('Buzz', 'DC/OS is the new black!');
   

8. Query the data back to make sure it persisted correctly:

    cqlsh> SELECT * FROM demo.map;
