haproxy 似乎没有看到所有后端/副本

  • 772

我正在尝试haproxy向多个副本发出代理请求：

docker-compose.yml：

services:
  haproxy:
    image: haproxy:2.3-alpine
    volumes:
      - ./haproxy.cfg:/usr/local/etc/haproxy/haproxy.cfg
    ports:
      - 8888:80
  app:
    build: .
    command: perl app.pl
    init: true
    deploy:
      replicas: 10

haproxy.cfg：

global
    maxconn  1024
listen in
    bind :80
    server-template srv 10 app:8080 check
    timeout connect 5000ms
    timeout client 50000ms
    timeout server 50000ms

但似乎只看到了一些复制品：

$ docker compose up
...
app-3      | MyWebServer: You can connect to your server at http://localhost:8080/
haproxy-1  | [NOTICE] 094/155107 (1) : New worker #1 (8) forked

    我不确定我是否理解原因，但depends_on据说可以解决问题（haproxy取决于apps）。我的猜测是haproxy缓存app启动时解析的内容。app如果此时并非所有s 都在运行，则它仅缓存正在运行的 IP。
