推荐Helm安装

1 Helm 环境搭建

需要golang和 Helm ， 下载二进制包解压：

导出环境变量： export PATH=$PATH:/softwares/go/bin export PATH=$PATH:/softwares/linux-amd64

2 安装

2.1 基于源码安装

下载源码到本地执行安装。 本方式方便更改源文件。

$ git clone https://github.com/emqx/emqx-chart

$ cd emqx-chart $ helm install --name myemqx --set deployment.image="emqx/emqx-edge:latest" .

2.2 repo安装

2.2.1 add repo

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

2.2.2 helm repo update

helm repo update

2.2.3 执行Helm (命名空间为：developer)

helm install my-emqx emqx/emqx -n developer

2.3 my-emqx svc 使用负载均衡

spec.type: LoadBalancer

$kubectl edit svc my-emqx -n developer

注： LoadBalancer 可以自己创建（在阿里云上，设备SVC spec.type: Balancer 会自动创建一个新的 LB）

使用已有的LoadBalancer 需要新增注解

annotations: service.beta.kubernetes.io/alicloud-loadbalancer-id: XXX service.beta.kubernetes.io/alicloud-loadbalancer-force-override-listeners: 'true' spec: type: LoadBalancer

如果在线编辑不生效，运行

helm upgrade my-emqx emqx/emqx -n developer

完整的SVC配置如下：其中：49.45.116.73 为 SLB 的公网

apiVersion: v1 kind: Service metadata: annotations: meta.helm.sh/release-name: my-emqx meta.helm.sh/release-namespace: developer service.beta.kubernetes.io/alicloud-loadbalancer-force-override-listeners: "true" service.beta.kubernetes.io/alicloud-loadbalancer-id: lb-bp1wrtjeumtikrw6yhx32 creationTimestamp: "2022-09-20T10:59:01Z" finalizers:

    • ip: 49.45.116.73

2.4 部署ingress

2.4.1 创建证书

准备key和pom格式的证书文件。 创建名为 my-emqx-ssl的k8s密钥。

kubectl create secret tls my-emqx-ssl --key=/home/jiangpeng25/cert/my-emqx.key --cert=/home/jiangpeng25/cert/my-emqx.pem -n developer

2.4.2 定义 Ingress

域名： my-emqx.XX.com ,

ingress.yaml 文件如下：spec.tls.hosts.secretName 使用my-emqx-ssl。

apiVersion: networking.k8s.io/v1 kind: Ingress metadata: annotations: nginx.ingress.kubernetes.io/proxy-read-timeout: "3600" nginx.ingress.kubernetes.io/proxy-send-timeout: "3600" name: my-emqx-ingress spec: tls:

  • hosts:
    • my-emqx.XX.com secretName: my-emqx-ssl rules:
  • host: my-emqx.XX.com http: paths: - path: / pathType: Prefix backend: service: name: my-emqx port: number: 18083 - path: /mqtt pathType: Prefix backend: service: name: my-emqx port: number: 8083 - path: / pathType: Prefix backend: service: name: my-emqx port: number: 1883

$ kubectl apply -f ingress.ymal -n developer

注意： Helm 的安装包在：~/.cache/helm/repository 文件夹中可以找到。
