host

Matches the Host the caller used. This is the predicate for a gateway serving several sites, or for the same application published under a customer name.

Parameters

Name	Type	Required	What it does
`hosts`	list of strings	yes	Exact names or `.suffix` wildcards, e.g. `shop.example.com`, `.example.com`. Several act as OR.

Example

predicates:
  - type: host
    args:
      hosts:
        - shop.example.com
        - '*.shop.example.com'
  - type: path
    args:
      patterns:
        - /**

Notes

The port is ignored: shop.example.com matches shop.example.com:8443.

A wildcard covers subdomains only: *.example.com matches app.example.com, and not example.com. Name the bare domain as well when you want both.
