License Configuration (EMQX Enterprise)

Task Target

• Configure EMQX Enterprise License.

Configure License

EMQX Enterprise License can be applied for free on EMQ official website: Apply for EMQX Enterprise License (opens new window).

The following is the relevant configuration of EMQX Custom Resource. You can choose the corresponding APIVersion according to the version of EMQX you want to deploy. For the specific compatibility relationship, please refer to EMQX Operator Compatibility:

Configure EMQX Cluster

• Create Secret based on License file

  A Secret is an object that contains a small amount of sensitive information such as a password, token, or key. For more detailed documentation on Secret, please refer to: Secret (opens new window). EMQX Operator supports using Secret to mount License information, so we need to create a Secret based on the License before creating an EMQX cluster.

  $ kubectl create secret generic ${your_license_name} --from-file=emqx.lic=${/path/to/license/file}
  

  ${your_license_name} represents the name of the created Secret.

  ${/path/to/license/file} represents the path of the EMQX Enterprise Edition License file, which can be an absolute path or a relative path. For more details on using kubectl to create a Secret, please refer to the document: Using kubectl to create a secret (opens new window).

• Save the following content as a YAML file and deploy it via the kubectl apply command

  apps.emqx.io/v1beta4 EmqxEnterprise supports configuring EMQX Enterprise License through .spec.license field. For more information, please refer to: license.

  apiVersion: apps.emqx.io/v1beta4
  kind: EmqxEnterprise
  metadata:
    name: emqx-ee
  spec:
    license:
      secretName: ${your_license_name}
    template:
      spec:
        emqxContainer:
          image:
            repository: emqx/emqx-ee
            version: 4.4.14
    serviceTemplate:
      spec:
        type: LoadBalancer
  

  secretName represents the name of the Secret created in the previous step.

• Wait for the EMQX cluster to be ready, you can check the status of the EMQX cluster through kubectl get command, please make sure STATUS is Running, this may take some time

  $ kubectl get emqxenterprises
  NAME      STATUS   AGE
  emqx-ee   Running  8m33s
  

• Obtain the External IP of EMQX cluster and access EMQX console

  $ kubectl get svc emqx-ee -o json | jq '.status.loadBalancer.ingress[0].ip'
  
  192.168.1.200
  

  Access http://192.168.1.200:18083 through a browser, and use the default username and password admin/public to login EMQX console.

apps.emqx.io/v2alpha1 EMQX supports configuring EMQX cluster license through .spec.bootstrapConfig. For bootstrapConfig configuration, please refer to the document: bootstrapConfig (opens new window). This field is only allowed to be configured when creating an EMQX cluster, and does not support updating.

After the EMQX cluster is created, if the license needs to be updated, please update it through the EMQX Dashboard.

• Save the following content as a YAML file and deploy it via the kubectl apply command

  apiVersion: apps.emqx.io/v2alpha1
  kind: EMQX
  metadata:
    name: emqx-ee
  spec:
    bootstrapConfig: |
      license {
        key = "..."
      }
    image: emqx/emqx-enterprise:5.0.0
    dashboardServiceTemplate:
      spec:
        type: LoadBalancer
  

  The license.key in the bootstrapConfig field represents the Licesne content. In this example, the License content is omitted, please fill it in by the user.

• Wait for the EMQX cluster to be ready, you can check the status of the EMQX cluster through kubectl get command, please make sure STATUS is Running, this may take some time

  $ kubectl get emqx emqx
  NAME   IMAGE      STATUS    AGE
  emqx   emqx:5.0   Running   10m
  

• Obtain the Dashboard External IP of EMQX cluster and access EMQX console

  EMQX Operator will create two EMQX Service resources, one is emqx-dashboard and the other is emqx-listeners, corresponding to EMQX console and EMQX listening port respectively.

  $ kubectl get svc emqx-dashboard -o json | jq '.status.loadBalancer.ingress[0].ip'
  
  192.168.1.200
  

  Access http://192.168.1.200:18083 through a browser, and use the default username and password admin/public to login EMQX console.

Update License

• View License Information

  $ kubectl exec -it emqx-ee-core-0 -c emqx -- emqx_ctl license info
  

  The following output can be obtained. From the output results, we can see the basic information of the license we applied for, including the applicant's information, the maximum number of connections supported by the license, and the expiration time of the license.

  customer        : EMQ
  email           : cloudnative@emqx.io
  deployment      : deployment-6159820
  max_connections : 10000
  start_at        : 2023-02-16
  expiry_at       : 2023-05-17
  type            : trial
  customer_type   : 0
  expiry          : false
  

• Update License

  • Update EMQX Enterprise License Secret

    $ kubectl create secret generic ${your_license_name} --from-file=emqx.lic=${/path/to/license/file} --dry-run -o yaml | kubectl apply -f -
    

  • Check whether the EMQX cluster license has been updated

    $ kubectl exec -it emqx-ee-0 -c emqx -- emqx_ctl license info
    

    You can get information similar to the following. From the max_connections field, you can see that the content of the License has been updated, which means that the EMQX Enterprise Edition License has been updated successfully. If the certificate information is not updated, you can wait for a while, the update of the license will be delayed.

    customer                 : cloudnative
    email                    : cloudnative@emqx.io
    max_connections          : 100000
    original_max_connections : 100000
