DNS local con LocalDNSServer

LocalDNSServer es un servidor DNS UDP autoritativo con fallback opcional a upstream.

from wsbuilder import LocalDNSServer

dns = LocalDNSServer(
    host="127.0.0.1",

    ttl=60,
    records={
        "demo.local": {"A": "127.0.0.1"},
        "api.demo.local": {"CNAME": "demo.local"},
    },
)
dns.start()

• add_raw_record
• remove_record
• clear_records

Proxy HTTP con ProxyI

ProxyI es una capa de reverse proxy y balanceo sin dependencias externas.

from wsbuilder import ProxyI

proxy = ProxyI(name="edge")
proxy.vhost("api.test.local", name="api-vhost").location("/api").upstream(
    "http://127.0.0.1:9000",
    name="backend-1",
).build()

Construccion de reglas

ProxyRouteBuilder soporta filtros por:

• host exacto, multiples hosts, host parcial o regex.
• path exacto, prefijo, contains o regex.
• headers con equals, contains o regex.
• metodos y prioridad.

Tambien permite:

• balance(value)
• strip_prefix(value=True)
• preserve_host(value=True)
• hash_key(value)
• default(value=True)
• upstream(target, **kwargs)

Estrategias de balanceo

La API publica expone:

• round_robin
• weighted_round_robin
• random
• least_connections
• least_response_time
• least_requests
• least_bytes_in
• least_bytes_out
• ip_hash
• consistent_hash
• first_available
• power_of_two_choices
• best

Instalacion sobre App

proxy.install(
    app,
    metrics_path="/api/proxy/metrics",
    stream_path="/api/proxy/metrics/stream",
    dashboard_path="/proxy",
)

Eso publica:

• snapshot JSON de metricas del proxy
• stream de metricas
• dashboard HTML

Para despachar trafico real, una ruta HTTP de tu aplicacion debe invocar app.proxyi.dispatch(request).
