在Docker中通过Nginx将mqtt.js客户端连接到Mosca Broker (相同的Docker-compose)
在Docker中通过Nginx将mqtt.js客户端连接到Mosca Broker (相同的Docker-compose)
提问于 2018-05-30 23:54:50
我有：
- 1 MongoDB
- 2 Mqtt Mosca Broker
- 2 NodeJS应用程序都带有mqtt.js cient
- 1 ngnix
<代码>F29
Nginx负载平衡和proxy_pass分别到NodeJS应用程序和mqtt Mosca Broker，
所以我有：
mqtt传感器-> nginx -> Mqtt Mosca Broker "flow“正常工作
浏览器-> nginx -> NodeJS应用“流程正常”
我不能做的是让NodeJS应用程序(mqtt.js客户端部分)通过nginx连接到Mqtt Mosca Broker，比如：
NodeJS (mqtt.js客户端) -> nginx -> Mqtt Mosca Broker。
奇怪的是，如果我尝试：
NodeJS (mqtt.js客户端) -> Mqtt Mosca代理流程正常工作
我有以下配置：
docker-compose.yml
nginx:
build: ./nginx
links:
- app1:app1
- app2:app2
- mqttbroker1:mqttbroker1
- mqttbroker2:mqttbroker2
ports:
- "80:80"
- "443:443"
- "1883:18833"
app1:
build: ./node_app
links:
- mongo:mongo
- mqttbroker1:mqttbroker1
- mqttbroker2:mqttbroker2
ports:
- "3000"
environment:
- NODE_ENV=production
- PORT=3000
app2:
build: ./node_app
links:
- mongo:mongo
- mqttbroker1:mqttbroker1
- mqttbroker2:mqttbroker2
ports:
- "3000"
environment:
- NODE_ENV=production
- PORT=3000
mqttbroker1:
build: ./node_broker
links:
- mongo:mongo
ports:
- "18831"
environment:
- NODE_ENV=production
mqttbroker2:
build: ./node_broker
links:
- mongo:mongo
ports:
- "18831"
environment:
- NODE_ENV=production
mongo:
container_name: mongo
restart: always
image: mongo
volumes:
- ./mongo/data:/data/db
ports:
- "27017:27017"nginx.conf (节选)
stream {
upstream mqtt_cluster{
server mqttbroker1:18831 max_fails=3 fail_timeout=30s;
server mqttbroker2:18831 max_fails=3 fail_timeout=30s;
}
server {
listen 18833; #mqtt continer prot mapped on std port (1883:18833)
proxy_pass mqtt_cluster;
}
}基本上，如果在我使用的NodeJS应用程序中：
const mqttClient = mqtt.connect('mqtt://mqttbroker1:18831', { clientId: clientId });它是有效的，但如果我试一下：
const mqttClient = mqtt.connect('mqtt://nginx:18833', { clientId: clientId });什么都不能用，有人能帮上忙吗？

我找到了一个使用docker-compose.yml的解决方案
我使用的不是link，而是depends_on和网络
YML文件是：
version: '3'
services:
nginx:
build: ./nginx
depends_on:
- app1
- app2
- mqttbroker1
- mqttbroker2
ports:
- "80:80"
- "443:443"
- "1883:1883"
networks:
main:
aliases:
- proxy
app1:
build: ./node_app
depends_on:
- mongo
- mqttbroker1
- mqttbroker2
ports:
- "3000"
environment:
- NODE_ENV=production
- PORT=3000
networks:
main:
aliases:
- app1
app2:
build: ./node_app
depends_on:
- mongo
- mqttbroker1
- mqttbroker2
ports:
- "3000"
environment:
- NODE_ENV=production
- PORT=3000
networks:
main:
aliases:
- app2
mqttbroker1:
build: ./node_broker
depends_on:
- mongo
ports:
- "18831"
environment:
- NODE_ENV=production
networks:
main:
aliases:
- mqttbroker1
mqttbroker2:
build: ./node_broker
depends_on:
- mongo
ports:
- "18831"
environment:
- NODE_ENV=production
networks:
main:
aliases:
- mqttbroker2
mongo:
container_name: mongo
restart: always
image: mongo
volumes:
- ./mongo/data:/data/db
ports:
- "27017:27017"
networks:
main:
aliases:
- mongo
networks:
main:我使用这个来通过mqtt连接：
const mqttClient = mqtt.connect('mqtt://proxy', { clientId: clientId });页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
