Manage License

Objective

• Configure the EMQX Enterprise license.
• Update EMQX Enterprise license.

Configure License

You can apply for an EMQX Enterprise license for free on the EMQX official website: Apply for EMQX Enterprise License.

Configure EMQX Cluster

EMQX CRD apps.emqx.io/v2beta1 supports configuring the EMQX cluster license through the .spec.config.data field. Refer to the Configuration Manual for complete configuration reference.

1. Save the following as a YAML file and deploy it using kubectl apply.

apiVersion: apps.emqx.io/v2beta1
kind: EMQX
metadata:
  name: emqx-ee
spec:
  config:
    data: |
      license {
        key = "..."
      }
  image: emqx/emqx:6.0.1
  dashboardServiceTemplate:
    spec:
      type: LoadBalancer

TIP

The license.key in the .spec.config.data field represents the license content. In this example, the license content is omitted. Please fill it in with your own license key.

2. Wait for the EMQX cluster to become ready.

Check the status of the EMQX cluster with kubectl get and ensure that STATUS is Ready. This may take some time.

$ kubectl get emqx emqx-ee
NAME   STATUS   AGE
emqx   Ready    10m

Update License

1. View the license information.

$ kubectl exec -it service/emqx-ee-headless -c emqx -- emqx ctl license info
customer        : Evaluation
email           : contact@emqx.io
deployment      : default
max_connections : 100
start_at        : 2023-01-09
expiry_at       : 2028-01-08
type            : trial
customer_type   : 10
expiry          : false

The output shows basic license information, including the applicant's information, the maximum number of connections supported by the license, and the expiration time.

2. Modify the EMQX CR to update the license.

$ kubectl edit emqx emqx-ee
...
spec:
  image: emqx/emqx:6.0.1
  config:
    data: |
      license {
        key = "${new_license_key}"
      }
...

3. Verify that the license has been updated.

$ kubectl exec -it service/emqx-ee-headless -c emqx -- emqx ctl license info
customer        : Evaluation
email           : contact@emqx.io
deployment      : default
max_connections : 100000
start_at        : 2023-01-09
expiry_at       : 2028-01-08
type            : trial
customer_type   : 10
expiry          : false

The updated max_connections field clearly indicates that the EMQX Enterprise license has been updated successfully. Keep in mind that the license update may take time, so you may need to retry the command.
