We are going to deploy Mule applications that use the GridGain Connector for Mule 4 in a Kubernetes cluster, so at this point you need to install a valid license prior to deploy them, if you haven't installed it yet.
Contact Hawkore to request for a TRIAL license for the GridGain Connector for Mule4.
Ensure Spring Boot GridGain Server is running, then open HK license manager in your browser http://ignite-rest.local/hk-license/hk-license-ui.html and follow steps to install and activate provided license.
