Summary

How to configure

Core

YAML/JSON setting	Type	Usage	Schemes
to	URL	optional	http, https, tcp

Enterprise

Set To in the Console:

Kubernetes

See Kubernetes Ingress for more information.

Target multiple upstream resources

Multiple upstream resources can be targeted by using a list instead of a single URL:

- from: https://example.com
  to:
    - https://a.example.com
    - https://b.example.com

Set load balancing weight

A load balancing weight may be associated with a particular upstream by appending ,[weight] to the URL. The exact behavior depends on your lb_policy setting. See Load Balancing for example configurations.

- from: https://example.com
  to: ['http://a', 'http://b']

- from: https://example.com
  to: ['http://a,10', 'http://b,20']

Must be tcp if from is tcp+https.

Examples

- from: https://example.com
  to: http://verify

- from: https://example.com
  to: https://192.1.20.12:8080

- from: https://example.com
  to: http://neverssl.com

- from: https://example.com
  to: https://verify.pomerium.com/anything/

danger

Be careful with trailing slash.

With rule:

- from: https://verify.corp.example.com
  to: https://verify.pomerium.com/anything

Requests to https://verify.corp.example.com will be forwarded to https://verify.pomerium.com/anything, while requests to https://verify.corp.example.com/foo will be forwarded to https://verify.pomerium.com/anythingfoo.To make the request forwarded to https://httbin.org/anything/foo, you can use double slashes in your request https://httbin.corp.example.com//foo.

While the rule:

- from: https://verify.corp.example.com
  to: https://verify.pomerium.com/anything/

All requests to https://verify.corp.example.com/* will be forwarded to https://verify.pomerium.com/anything/*. That means accessing to https://verify.corp.example.com will be forwarded to https://verify.pomerium.com/anything/. That said, if your application does not handle trailing slash, the request will end up with 404 not found.

Either redirect or to must be set.
