利用 EMQX Operator 部署 EMQX 集群

EMQX Operator 最新信息, 请访问 github (opens new window).

1. 使用 cert-manager (opens new window) 给 webhook 服务提供证书，可以参考 cert-manager 文档 (opens new window) 安装

2. 可以通过如下两种方式之一来安装 Operator Controller：

   • 使用静态文件安装

   curl -f -L "https://github.com/emqx/emqx-operator/releases/download/1.2.2/emqx-operator-controller.yaml" | kubectl apply -f -

   • 使用 Helm 安装

     • 添加 EMQX Helm 仓库

     helm repo add emqx https://repos.emqx.io/charts
     helm repo update

     • 用 Helm 安装 EMQX Operator 控制器

     $ helm install emqx-operator emqx/emqx-operator \
       --set installCRDs=true \
       --namespace emqx-operator-system \
       --create-namespace

3. 检查 EMQX Operator 控制器状态

   $ kubectl get pods -l "control-plane=controller-manager" -n emqx-operator-system
   NAME READY STATUS RESTARTS AGE
   emqx-operator-controller-manager-68b866c8bf-kd4g6 1/1 Running 0 15s

4. 部署 EMQX Enterprise

• 部署 EMQX Custom Resource

  cat << "EOF" | kubectl apply -f -
  apiVersion: apps.emqx.io/v1beta3
  kind: EmqxEnterprise
  metadata:
    name: emqx-ee
    labels:
      "foo": "bar"
  spec:
    emqxTemplate:
      image: emqx/emqx-ee:4.4.5
  EOF

• 检查 EMQX 状态

  $ kubectl get pods
  NAME READY STATUS RESTARTS AGE
  emqx-ee-0 2/2 Running 0 22s
  emqx-ee-1 2/2 Running 0 22s
  emqx-ee-2 2/2 Running 0 22s
  $ kubectl exec -it emqx-ee-0 -c emqx -- emqx_ctl status
  Node 'emqx-ee@emqx-ee-0.emqx-ee-headless.default.svc.cluster.local' 4.4.5 is started
  $ kubectl exec -it emqx-ee-0 -c emqx -- emqx_ctl cluster status
  Cluster status: #{running_nodes =>
                     ['emqx-ee@emqx-ee-0.emqx-ee-headless.default.svc.cluster.local',
                      'emqx-ee@emqx-ee-1.emqx-ee-headless.default.svc.cluster.local',
                      'emqx-ee@emqx-ee-2.emqx-ee-headless.default.svc.cluster.local'],
                 stopped_nodes => []}
