Add a License
Please skip this step if you are using a HiveMQ trial license. If you do not have a valid HiveMQ license, the HiveMQ cluster uses a trial licence that allows up to 25 concurrent client connections and is limited to testing and evaluation purposes only. To obtain a HiveMQ licence that is suitable for production use, or request an evaluation licence that allows more connections, contact our customer service team.
If you have a valid HiveMQ license, create a hivemq-license Kubernetes ConfigMap from your licence file to make the licence information accessible for the HiveMQ deployment you execute in the next step.
Please replace hivemq-license.lic with your license name.
| Code Block |
|---|
kubectl create configmap hivemq-license --from-file=hivemq-license.lic |
Open your values.yaml file in a text editor
Search the hivemq-license configmap
| Code Block |

configMaps: []
# ConfigMaps to mount to the HiveMQ pods. These can be mounted to existing directories without shadowing the folder contents as well.
#- name: hivemq-license
# path: /opt/hivemq/license |
Uncomment the name and path variables, please make sure that name and path are properly aligned under configMaps

Save the file
The values.yaml contains resource definitions such as cpu , memory , disk size and others. In our case we use the following
nodecount: 3
cpu: "4"
memory: "4Gi"
ephemeralStorage: "15Gi"
Apply the changes to the cluster
| Code Block |
|---|
helm upgrade hivemq --install hivemq/hivemq-operator --values values.yaml |
Verify Licenseif HiveMQ Cluster is running successfully
Please make sure that pods are running successfully after the change, it may take some time for the pods to be ready

Check the Hivemq deployment log by running the following and checking for INFO - Started HiveMQ in XYZ ms
| Code Block |

If the log contains something similar to INFO - Using valid XYZ license, the license is successfully applied.
If the license is not correctly applied, you will see the following in logs
