Change the IP address of your Docker containers

By default, Docker containers in Splunk UBA use IP addresses in the 172.x.x.x range. If this conflicts with other network IP address ranges in your environment, perform the tasks below to customize your Docker IP ranges. In this example, we will change the default 172.x.x.x addresses to 192.168.0.1/24. Be sure to replace the example values with the actual values appropriate for your environment.

  1. Login to the Splunk UBA management server as the Caspida user.
  2. Stop all Splunk UBA services:
    /opt/caspida/bin/Caspida stop-all
  3. Run the following command on all nodes in the cluster:
    sudo service docker stop
  4. Add the following property and value to /etc/caspida/local/conf/uba-site.properties:
    system.docker.networkcidr=192.168.0.1/24
  5. Run the following command:
    /opt/caspida/bin/Caspida replace-properties
  6. In distributed deployments, synchronize the cluster:
    /opt/caspida/bin/Caspida sync-cluster
  7. Restart all nodes in your cluster to ensure that the new IP range is in use.
  8. Start all Splunk UBA services:
    /opt/caspida/bin/Caspida start-all
  9. Run the ifconfig docker0 command to verify that the correct address range is being used. For example:
    caspida@uba-001:~$ ifconfig docker0
    docker0 Link encap:Ethernet HWaddr 02:42:7a:6a:d9:1d 
            inet addr:192.168.0.1 Bcast:0.0.0.0 Mask:255.255.255.0
            inet6 addr: fe80::42:7aff:fe6a:d91d/64 Scope:Link
