2022-12-29：nsq是go语言写的消息队列。请问k3s部署nsq，yaml如何写？

答案2022-12-29：

yaml如下：

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: nsq
  name: nsq
  namespace: moonfdd
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nsq
  template:
    metadata:
      labels:
        app: nsq
    spec:
      containers:
        - image: "nsqio/nsq"
          imagePullPolicy: IfNotPresent
          name: nsqlookupd
          args:
            - "/nsqlookupd"
        - image: "nsqio/nsq"
          imagePullPolicy: IfNotPresent
          name: nsqd
          args:
            - "/nsqd"
            - "--lookupd-tcp-address"
            - "localhost:4160"
          volumeMounts:
            - mountPath: /data
              name: volv2
        - image: "nsqio/nsq"
          imagePullPolicy: IfNotPresent
          name: nsqadmin
          args:
            - "/nsqadmin"
            - "--lookupd-http-address"
            - "localhost:4161"
      volumes:
        - hostPath:
            path: /root/k8s/moonfdd/nsq/data
            type: DirectoryOrCreate
          name: volv2
---
apiVersion: v1
kind: Service
metadata:
  labels:
    app: nsq
  name: nsq
  namespace: moonfdd
spec:
  ports:
    - name: nsqlookupd0
      port: 4160
      protocol: TCP
      targetPort: 4160
    - name: nsqlookupd1
      port: 4161
      protocol: TCP
      targetPort: 4161
    - name: nsqd0
      port: 4150
      protocol: TCP
      targetPort: 4150
    - name: nsqd1
      port: 4151
      protocol: TCP
      targetPort: 4151
    - name: nsqadmin
      port: 4171
      protocol: TCP
      targetPort: 4171
  selector:
    app: nsq
  type: NodePort

从service得知web端口和curl命令的端口

web端口是58395
curl命令端口是36055

进入web页面，可以看到topics里啥都没有

敲curl命令，给nsq增加topic，名称是test

刷新web页面，可以看到topics里有test名称
