Define a single origin rule using Terraform

Create an origin rule using Terraform to override the Host header, the resolved hostname, and the destination port of API requests.

The following example defines a single origin rule for a zone using Terraform. The rule overrides the Host header, the resolved hostname, and the destination port of API requests.

# Change origin for API requests
resource "cloudflare_ruleset" "http_origin_example" {
zone_id = "<ZONE_ID>"
name = "Change origin"
description = ""
kind = "zone"
phase = "http_request_origin"
rules {
action = "route"
action_parameters {
host_header = "example.net"
origin {
host = "example.net"
port = 8000
}
}
expression = "(http.request.uri.path matches \"^/api/\")"
description = "Change origin of API requests"
enabled = true
}
}
