大佬教程收集整理的这篇文章主要介绍了node.js – Google容器引擎(Kubernetes)：Websocket(Socket.io)无法处理多个副本，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我的节点应用程序是用Hapi.js和Socket.io开发的,我的结构如下图所示.
我正在使用Glue编写Hapi服务器.下面是我的manifest.json
{ ... "connections": [ { "host": "app","address": "0.0.0.0","port": 8000,"labels": ["api"],"routes": { "cors": false,"security": { "hsts": false,"xframe": true,"xss": true,"noOpen": true,"noSniff": true } },"router": { "StripTrailingSlash": true },"load": { "maxHeapUsedBytes": 1073741824,"maxRSSBytes": 1610612736,"maxEventLoopDelay": 5000 } },{ "host": "app","port": 8099,"labels": ["web"],"routes": { "cors": true,"port": 8999,"labels": ["admin"],"maxEventLoopDelay": 5000 },"state": { "ttl": null,"isSecure": false,"ishttpOnly": true,"path": null,"domain": null,"encoding": "none","clearInvalid": false,"StrictHeader": true } } ],... }
还有我的Nginx.conf
worker_processes 5; ## Default: 1 worker_rlimit_nofile 8192; error_log /dev/stdout info; events { worker_connections 4096; ## Default: 1024 } http { access_log /dev/stdout; server { listen 80 default_server; listen [::]:80 default_server; # Redirect all http requests to httpS with a 301 Moved PeRMANently response. return 301 https://$host$request_uri; } server { listen 443 ssl default_server; listen [::]:443 ssl default_server; server_name _; # Configure ssl ssl_certificate /etc/secret/ssl/myapp.com.csr; ssl_certificate_key /etc/secret/ssl/myapp.com.key; include /etc/Nginx/ssl-params.conf; } server { listen 443 ssl; listen [::]:443 ssl; server_name api.myapp.com; LOCATIOn / { proxy_pass http://api_app/; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-ForWARDed-For $proxy_add_x_forWARDed_for; # Handle Web Socket connections proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } } server { listen 443 ssl; listen [::]:443 ssl; server_name myapp.com; LOCATIOn / { proxy_pass http://web_app/; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-ForWARDed-For $proxy_add_x_forWARDed_for; # Handle Web Socket connections proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } } server { listen 443 ssl; listen [::]:443 ssl; server_name admin.myapp.com; LOCATIOn / { proxy_pass http://admin_app/; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-ForWARDed-For $proxy_add_x_forWARDed_for; # Handle Web Socket connections proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } } # Define your "upstream" servers - the # servers request will be sent to upstream api_app { server localhost:8000; } upstream web_app { server localhost:8099; } upstream admin_app { server localhost:8999; } }
Kubernetes服务app-service.yaml

这是Nginx的日志：

当我在app-deployment.yaml中将副本更改为1时,它可以正常工作.但我认为这不是一个好的解决方案.我需要3个复制品.
apiVersion: extensions/v1beta1
kind: Deployment
Metadata:
name: app-Nginx
spec:
replicas: 1
template:
Metadata:
labels:
app: app-Nginx
如何使它与3个副本一起使用？
Error during WebSocket handshake: Unexpected response code: 400
但是,我仍然从服务器获取数据.所以我觉得没关系.
更新了服务模板
apiVersion: v1 kind: service Metadata: name: app-Nginx labels: app: app-Nginx spec: sessionAffinity: ClientIP type: LoadBalancer ports: # The port that this service should serve on. - port: 80 targetPort: 80 protocol: TCP name: http - port: 443 targetPort: 443 protocol: TCP name: https # Label keys and values that must match in order # to receive traffic for this service. SELEctor: app: app-Nginx
