There are existing Kubernetes concepts which allows you to expose a single service. However, you can do so through an AppsCode Ingress as well, simply by specifying a default backend with no rules.
apiVersion: voyager.appscode.com/v1beta1 kind: Ingress metadata: name: test-ingress namespace: default spec: backend: serviceName: test-service servicePort: '80'
This will create a load balancer forwarding all traffic to
test-server service, unconditionally. The
loadbalancer ip can be found inside
Status Field of the loadbalancer described response. If there are other
rules defined in Ingress then the loadbalancer will forward traffic to the
test-server when no other
apiVersion: voyager.appscode.com/v1beta1 kind: Ingress metadata: name: test-ingress namespace: default spec: backend: serviceName: test-service servicePort: '80' rules: - host: appscode.example.com http: paths: - backend: serviceName: test-service servicePort: '80'
Default Backend: An Ingress with no rules, like the one shown in the previous section, sends all traffic to a single default backend. You can use the same technique to tell a loadbalancer where to find your website’s 404 page, by specifying a set of rules and a default backend. Traffic is routed to your default backend if none of the Hosts in your Ingress matches the Host in request header, and/or none of the paths match url of request.
This Ingress will forward traffic to
test-service if request comes from the host
Other requests will be forwarded to default backend.
Default Backend also supports
