service

service is Turna's reverse proxy middleware. It can proxy to one or more upstream servers with round-robin balancing, or select upstreams by request path prefix.

server:
  http:
    middlewares:
      backend:
        service:
          insecure_skip_verify: false
          pass_host_header: true
          loadbalancer:
            servers:
              - url: http://localhost:3000
              - url: http://localhost:3001

Fields

Field	Default	Description
insecure_skip_verify	false	Skip upstream TLS certificate verification.
pass_host_header		When explicitly false, clear r.Host before proxying.
loadbalancer.servers		Round-robin upstream list.
prefixbalancer.prefixes		Path-prefix-specific upstream lists.
prefixbalancer.default_servers		Default upstreams when no prefix matches.

Prefix Balancer

service:
  prefixbalancer:
    prefixes:
      - prefix: /api
        servers:
          - url: http://api:3000
      - prefix: /admin
        servers:
          - url: http://admin:3000
    default_servers:
      - url: http://web:3000

If the prefix balancer is configured, it is used instead of the plain loadbalancer.
