haproxy não parece ver todos os backends/réplicas

  • 772

Estou tentando fazer haproxysolicitações de proxy para várias réplicas:

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

Mas parece ver apenas algumas das réplicas:

$ 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
app-4      | MyWebServer: You can connect to your server at http://localhost:8080/

    Não tenho certeza se entendi o motivo, mas depends_onsupostamente resolve o problema ( haproxydepende do apps). Meu palpite é que haproxyarmazena em cache o que appé resolvido quando é iniciado. Se nem todos os appprogramas estiverem em execução naquele momento, ele armazena em cache apenas os IPs em execução.
