BackendGroups with namespace starts with digit doesn't proxy_passed to split_clients correctly #2606

eseiker · 2024-09-26T06:48:48Z

Describe the bug
BackendGroups with namespace starts with digit doesn't proxy_passed to split_clients correctly.
For example, we have a namespace named 9c-network and one of its routes has multiple backends.
So ngf creates a split_clients named $9c_network__some_route_name_rule0 and generates a line proxy_pass http://$9c_network__some_route_name_rule0$request_uri;
However, it seems nginx processes the proxy_pass parameter as $9, c_network__..., not $9c_network__....
nginx responds with 502 Bad Gateway and I found a log that says no resolver defined to resolve c_network__some_route_name_rule0.
I suspect nginx think it's regex capture group if a split_clients starts with number.

To Reproduce
Steps to reproduce the behavior:

create a namespace which its name starts with a digit
create a random HTTPRoute in the namespace with parentRef pointing nginx-gateway-fabric
http request to the route and see if it works

Expected behavior
responds with 2xx~4xx, not 502 Bad Gateway

Set $gw_api_compliant_host variable to the value of $http_host unless $http_host is empty, then set it to the value
of $host. We prefer $http_host because it contains the original value of the host header, which is required by the
Gateway API. However, in an HTTP/1.0 request, it's possible that $http_host can be empty. In this case, we will use
the value of $host. See http://nginx.org/en/docs/http/ngx_http_core_module.html#var_host.
map $http_host $gw_api_compliant_host {

'' $host;

default $http_host;

}
Set $connection_header variable to upgrade when the $http_upgrade header is set, otherwise, set it to close. This
allows support for websocket connections. See https://nginx.org/en/docs/http/websocket.html.

Additional context
I think it can be resolved by simply adding something before first %s

nginx-gateway-fabric/internal/mode/static/state/dataplane/types.go

Line 258 in 88269ac

    
           return fmt.Sprintf("%s__%s_rule%d", bg.Source.Namespace, bg.Source.Name, bg.RuleIdx)

configuration file /etc/nginx/conf.d/http.conf:

Set $gw_api_compliant_host variable to the value of $http_host unless $http_host is empty, then set it to the value

of $host. We prefer $http_host because it contains the original value of the host header, which is required by the

Gateway API. However, in an HTTP/1.0 request, it's possible that $http_host can be empty. In this case, we will use

the value of $host. See http://nginx.org/en/docs/http/ngx_http_core_module.html#var_host.

Set $connection_header variable to upgrade when the $http_upgrade header is set, otherwise, set it to close. This

allows support for websocket connections. See https://nginx.org/en/docs/http/websocket.html.

Returns just the path from the original request URI.
