ECP provides a fast deployment method based on Kubernetes, which helps users quickly build the ECP cloud-edge integrated platform. In this chapter, users can experience the features and capabilities of ECP in just a few simple steps.
- First, install ECP. Users need a cloud-native Kubernetes environment and an ECP installation package (You can contact EMQ for the installation package).
- Then, log in to ECP to enter the System Management interface and initialize the environment.
- Finally, in ECP's Workspace interface, deploy EMQX cluster and edge services like Neuron and eKuiper with one click to start experiencing various services and functions of ECP.
To install ECP, please refer to Deploy ECP based on Kubernetes.
Initialize the ECP Environment
After installation, the following configurations need to be completed on ECP before you can leverage the centralized management power of ECP.
|Configure the license||Prepare and install the ECP license.|
|Configure Kubernetes connections||Connect ECP to Kubernetes, so ECP can manage, control, and authenticate Kubernetes resources.|
|Configure storage classes||A storage class is a Kubernetes resource type used to specify the PV volume of storage resources assigned to the cluster during creation.|
|Configure EMQX cluster image||Select the version of the EMQX cluster during installation and upgrade.|
|Configure EMQX cluster specifications||Specify the resources for the EMQX cluster during installation and upgrade.|
|Install the edge service image||Select the version of the edge service during installation and upgrade.|
|Configure edge service specifications||Specify the resources for the edge service during installation and upgrade.|
Configure the License

- Log in as superuser, switch to the Workspace interface, and click License Management on the left navigation menu.
- Click Update License and upload the license obtained in Step 1; you can see the license details on this page.
Configure Kubernetes Connections
Log in to the Kubernetes master node.
In Kubernetes command line tool, run the command below to locate the default configuration file. Download the file to your local machine.
In the Workspace interface, click System Settings > Resource Settings on the left navigation menu.
Then click on the Kubernetes Connect Settings and click Create Kubernetes Connect, upload the configuration file you downloaded in Step 2. ECP now can call the Kubernetes APIs and resources.
Configure Storage Class
Configuring storage classes is an important step when setting up resource specifications for cloud clusters and edge services. This section takes EMQX cluster as an example to illustrate.
Log in to the Kubernetes environment via the command line.
Use the following command to view the list of storage classes, including system-provided storage classes or self-built ones:
kubectl get sc NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE alicloud-disk-ssd diskplugin.csi.alibabacloud.com Delete Immediate true 170d alicloud-disk-topology diskplugin.csi.alibabacloud.com Delete WaitForFirstConsumer true 170d local-path rancher.io/local-path Delete WaitForFirstConsumer false 169d
Go back to ECP and select one Storage Class for EMQX clusters (Administration -> System Settings -> Resource Settings -> Cluster Setting -> EMQX Quota List). Note: The Storage Class name should be identical to that on Kuberneets, set the storage size and whether to set it as a default option.
Save the settings, and the newly created storage class will take effect immediately.

For a detailed explanation of each field, see Resource Setting - EMQX Cluster Quota
Use ECP to Create Services
Once you have set up the underlying Kubernetes environment, you can start experiencing the various features of ECP.
|Create Organization/Project||ECP follows a multi-tenant, multi-project management approach, before officially starting with ECP to manage your EMQX Clusters and edge services, the first step is to create an organization and a project.|
|Install and Manage EMQX Clusters||Experience creating and managing EMQX clusters using ECP.|
|Install and Manage Edge Service Instance||Experience creating and managing edge services using ECP.|
Create Organization and Project
ECP follows a multi-tenant, multi-project management approach, where building EMQX clusters and installing Neuron and eKuiper services are based on specific projects. Therefore, the first step is to create an organization and a project.
Log in as a system admin and click to switch to the Administration page.
Click on Organizations in the left sidebar.
On the Organizations page, click Create Organization.
In the popup dialog box, set as follows:
- Enter the Organization Name, for example, EMQ.
- Click to select the organization members in the Candidates panel, and assign one or multiple organization members as organization admin in the Member panel.
Click Create to save the input.
Then on the Projects page, repeat the same step to create your project.
After you have created your organization and project, you can click the Workspace icon to switch to the Workspace page and start using EMQX to manage your EMQX clusters and edge services.
Install and Manage EMQX Clusters
Once the organization and project are ready, you can proceed to create EMQX clusters using ECP. Switch to the Workspace interface and select the EMQ organization and ECP project you just created. You will be directed to the Cluster page.
On the Clusters page, click Add Cluster to open the cluster creation page, and set it as follows:
- Select New Cluster as Cluster Type.
- Enter a desired Cluster Name, such as emqx-test.
- Keep the default Connection Limit of 10.
- Choose the default 1C2G specification.
- Under Replicas, select 1 for the number of nodes.
- Use the default image version.
- Click Confirm to create the cluster.
The newly-created clusters will be listed in the Cluster List panel with the status Creating. Wait till the status changes to Running, indicating the cluster is ready for production use.
