Configuring Riak networking

When you install Riak on an IBM Cloud® engineered server, Riak is bound to the private network IP address. Binding Riak minimizes the security risks of having an open, accessible Riak instance exposed publicly upon deployment. At any time, the IP address that is bound to Riak can be changed.

Do not expose Riak openly to public interfaces without other security measures in place to limit external access to the instance (for example, firewalls and iptables).

Complete the following steps to configure Riak networking to bind to a new interface.

Binding Riak to a new interface

Go to the riak_core section of the /etc/riak/app.config file in the installation.
Update the http{} attribute in the riak_core section to reflect the new IP address to which Riak is bound. {http, [ {"127.0.0.1", 8098 } ] },
Locate the /etc/vm.args file in the installation.
Edit the -name attribute within the /etc/vm.args file to reflect the new IP address: -name riak@127.0.0.1
Restart Riak to complete the binding changes.

Next steps

The changes that are made to the bind impact all previous binds to any interfaces associated with the Riak instance. After restart, the bound IP address is updated and functioning properly. If you restart the Riak instance and it does not result in a successful bind, contact Support.
