Configuration options for HAProxy backend services

HAProxy Backend Configuration¶

This parameter defines configuration options for HAProxy backend sections, allowing per-service customization of load balancing, health checks, and other backend-specific settings.

For full documentation of all available directives, refer to the HAProxy Configuration Manual: https://www.haproxy.com/documentation/haproxy-configuration-manual/latest/#4.1

Requirements¶

Must use valid HAProxy backend configuration syntax
mode must match corresponding frontend service
Balance algorithm must be appropriate for the service type

Usage¶

Configure backend settings with mode, balance algorithm, and optional custom configuration:

haproxy/backend/config:
  http:
    mode: http
    balance: roundrobin
  postgres:
    mode: tcp
    balance: leastconn
    config: |
      option mysql-check user haproxy
  custom:
    mode: tcp
    config: |
      stick-table type ip size 200k expire 30m
      stick on src

The configuration supports: - mode: Connection mode (tcp/http/log) - balance: Load balancing algorithm - config: Custom configuration block for advanced settings

Common balance algorithms: - roundrobin: Each server is used in turns - leastconn: Server with least connections receives the connection - source: Based on source IP hash - uri: Based on URI hash for HTTP services
