Configuration options for HAProxy backend services

HAProxy Backend Service Configuration¶

This parameter defines additional HAProxy configuration directives for individual service instances on backend nodes. It allows per-service customization of connection limits, health checks, and other server-specific options.

Requirements¶

Must be defined on backend nodes (haproxy/role = backend)
Must use valid HAProxy server configuration syntax
Service names must match those defined in haproxy/backend/services

Usage¶

Define configuration options for services:

haproxy/backend/services/config:
  http: "maxconn 64"
  https: "verify none check check-ssl inter 10s fall 2 rise 3"
  postgres: "check port 5432 inter 2s rise 2 fall 3"

Example configurations for different service types:

haproxy/backend/services/config:
  # Basic web service with connection limit
  http: "maxconn 100"

  # SSL service with health checks
  https: "verify none check check-ssl inter 10s fall 2 rise 3"

  # Backup server configuration
  http_backup: "check backup inter 1s"

  # Database with custom check
  postgres: "check port 5432 inter 2s"

Common configuration options: - maxconn: Maximum connections to this server - check: Enable health checking - backup: Mark server as backup - inter: Health check interval - rise/fall: Success/failure counts for health status
