Getting Started

In this section, we will walk you through the steps required to efficiently set up the environment for the EMQX Operator, install the Operator, and then use it to deploy EMQX. By following the guidelines outlined in this section, you will be able to effectively install and manage EMQX using the EMQX Operator.

Prepare the Environment

Before deploying EMQX Operator, please confirm that the following components have been ready:

• A running Kubernetes cluster, for a version of Kubernetes, please check How to selector Kubernetes version

• A kubectl tool that can access the Kubernetes cluster. You can check the status of the Kubernetes cluster using kubectl cluster-info command.

• Helm 3 or higher

Install EMQX Operator

1. Install and start cert-manager.

   TIP

   cert-manager version 1.1.6 or higher is required. Skip this step if the cert-manager is already installed and started.

   You can use Helm to install cert-manager.

   $ helm repo add jetstack https://charts.jetstack.io
   $ helm repo update
   $ helm upgrade --install cert-manager jetstack/cert-manager \
     --namespace cert-manager \
     --create-namespace \
     --set installCRDs=true

   Or you can follow the cert-manager installation guide to install it.

   WARNING

   If you install cert-manager on Google Kubernetes Engine (GKE) with default configuration may cause bootstrapping issues. Therefore, by adding the configuration of --set global.leaderElection.namespace=cert-manager, configure to use a different namespace in leader election. Please check cert-manager compatibility

2. Install the EMQX Operator with the command below:

   $ helm repo add emqx https://repos.emqx.io/charts
   $ helm repo update
   $ helm upgrade --install emqx-operator emqx/emqx-operator \
     --namespace emqx-operator-system \
     --create-namespace

3. Wait till EMQX Operator is ready:

   $ kubectl wait --for=condition=Ready pods -l "control-plane=controller-manager" -n emqx-operator-system
   
   pod/emqx-operator-controller-manager-57bd7b8bd4-h2mcr condition met

Now that you have successfully installed the operator, you are ready to proceed to the next step. In the Deploy EMQX section, you will learn how to use the EMQX Operator to deploy EMQX.

Alternatively, if you are interested in learning how to upgrade or uninstall EMQX using the operator, you can continue reading this section.

Deploy EMQX

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

   apiVersion: apps.emqx.io/v2beta1
   kind: EMQX
   metadata:
      name: emqx-ee
   spec:
      image: emqx/emqx-enterprise:5.6

   For more details about the EMQX CRD, please check the reference document.

2. Wait the EMQX cluster is running.

   $ kubectl get emqx
   
   NAME      IMAGE                        STATUS    AGE
   emqx-ee   emqx/emqx-enterprise:5.1.0   Running   2m55s

   Make sure the STATUS is Running, it maybe takes some time to wait for the EMQX cluster to be ready.

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

   apiVersion: apps.emqx.io/v2beta1
   kind: EMQX
   metadata:
      name: emqx
   spec:
      image: emqx:5

   For more details about the EMQX CRD, please check the reference document.

2. Wait the EMQX cluster is running.

   $ kubectl get emqx
   
   NAME   IMAGE      STATUS    AGE
   emqx   emqx:5.1   Running   2m55s

   Make sure the STATUS is Running, it maybe takes some time to wait for the EMQX cluster to be ready.

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

   apiVersion: apps.emqx.io/v1beta4
   kind: EmqxEnterprise
   metadata:
      name: emqx-ee
   spec:
      template:
        spec:
          emqxContainer:
            image:
              repository: emqx/emqx-ee
              version: 4.4.17

   For more details please check the reference document.

2. Wait the EMQX cluster is running

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

   Make sure the STATUS is Running, it maybe takes some time to wait for the EMQX cluster to be ready.

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

   apiVersion: apps.emqx.io/v1beta4
   kind: EmqxBroker
   metadata:
      name: emqx
   spec:
      template:
        spec:
          emqxContainer:
            image:
              repository: emqx
              version: "4.4.18"

   For more details please check the reference document.

2. Wait the EMQX cluster is running.

   $ kubectl get emqxbrokers
   
   NAME   STATUS   AGE
   emqx   Running  8m33s

   Make sure the STATUS is Running, it maybe takes some time to wait for the EMQX cluster to be ready.
