Cassandra

Ansible role for installing and setting up Apache Cassandra.

Important Notes:

• Use Java version 8.
• Datastax community edition is no longer supported.
• The recommended cassandra_distro is apache.
• The ddc cassandra_distro will be phased out soon.

Usage Examples

- hosts: dbhost

  vars:
    cassandra_distro: apache
    cassandra_version: 3.11.2
    cassandra_cluster_name: myAwesomeCluster
    cassandra_seeds: [ "seedIp1", "seedIp2" ]  # Only use IP addresses
    cassandra_listen_address: "{{ ansible_eth0.ipv4.address }}"
    cassandra_rpc_address: "{{ ansible_eth0.ipv4.address }}"

  roles:
    - wunzeco.cassandra

Note:

If your seed nodes have fully qualified domain names (FQDN), use cassandra_seeds_fqdn instead of cassandra_seeds.

Testing

To perform integration tests for this role:

PLATFORM=ubuntu-1404            # other options include ubuntu-1604 or centos
kitchen verify $PLATFORM && kitchen destroy $PLATFORM

Note: The kitchen test command is not suitable for this role because both kitchen suites (instances) need to be active for all tests to succeed.
