我的Kubernetes上有一个Mosquitto经纪人。我可以连接到专用网络中的Mosquitto Broker。它运作良好。 但是,当我们使用公共域(我们使用Sophos UTM 9)时,客户端无法连接到Mosquitto Broker。
我是Kubernetes的新手。这是mosquitto.yaml文件:
apiVersion: apps/v1
kind: Deployment
metadata:
name: mosquitto
spec:
selector:
matchLabels:
app: mosquitto
replicas: 1
template:
metadata:
labels:
app: mosquitto
spec:
containers:
- name: mosquitto
image: eclipse-mosquitto:v1.16.10
resources:
limits:
cpu: "1"
memory: 2Gi
requests:
cpu: "1"
memory: 2Gi
imagePullPolicy: Always
ports:
- containerPort: 1883
---
apiVersion: v1
kind: Service
metadata:
name: mosquitto
spec:
externalIPs:
- xxx.xxx.xxx.xxx
type: ClusterIP
ports:
- name: mqtt
port: 1883
targetPort: 1883
protocol: TCP
selector:
app: mosquitto
我使用NodeJS来连接公共领域。此NodeJS代码为:
var mqtt = require('mqtt');
var client = mqtt.connect('mqtt://mydomain.com:1883');
client.on('connect', function () {
client.subscribe(topic)
console.log("Subscribed topic " + topic);
})
我想知道问题是kubernetes还是Sophos UTM9。我错过了什么吗?
我必须为Kubernetes上的Mosquitto使用公共域做什么?
我非常感谢。

在测试了yaml文件后,我得出的结论是您的配置几乎正确,这是因为:
eclipse-mosquitto:v1.16.10
图片不存在。您可以检查所有可用的标签here。因此,最可能的问题是您的pod可能未运行。您可以通过运行以下命令并检查列STATUS
来对其进行检查。
$ kubectl get pods -l=app=mosquitto
NAME READY STATUS RESTARTS AGE
mosquitto-c9dc57d59-98l8r 1/1 Running 0 5m53s
这对我有用。 注意:出于测试目的,我已从服务和部署中删除了externalIP
和resource limits
,并为eclipse-mosquitto:1.6.10
替换了图像:
apiVersion: apps/v1
kind: Deployment
metadata:
name: mosquitto
spec:
selector:
matchLabels:
app: mosquitto
replicas: 1
template:
metadata:
labels:
app: mosquitto
spec:
containers:
- name: mosquitto
image: eclipse-mosquitto:1.6.10
imagePullPolicy: Always
ports:
- containerPort: 1883
---
apiVersion: v1
kind: Service
metadata:
name: mosquitto
spec:
type: ClusterIP
ports:
- name: mqtt
port: 1883
targetPort: 1883
protocol: TCP
selector:
app: mosquitto
部署后,我已经使用dnsutil容器进行了测试(您可以找到规格here):
kubectl exec dnsutils -- sh -c 'apk update && apk add mosquitto-clients'
kubectl exec dnsutils -- mosquitto_pub -h mosquitto -t 'test/topic' -m 'upvoteIt'
检查蚊子荚中的日志:
kubectl logs mosquitto-xxxxx
1597829622: New client connected from 172.17.0.4 as mosqpub|88-dnsutils (p1, c1, k60).
1597829622: Client mosqpub|88-dnsutils disconnected.
如果要在测试前查看消息,请打开第二个终端并运行以下命令以查看mosquitto服务器正在接收的消息:
$ kubectl exec mosquitto-xxxxx -- mosquitto_sub -v -t 'test/topic'
test/topic upvoteIt
其中mosquitto-xxxxx是您的广告连播的名称。
