Non HTTP Services / TCP Ingress

Accessing a TCP or UDP service without using the provided OpenShift router via the route object is possible via a Load Balancer type service.

To use it just create a service with the type LoadBalancer. Example:

apiVersion: v1
kind: Service
metadata:
  name: myapp
spec:
  ports:
  - name: mytcpapp
    port: 5000
  type: LoadBalancer
  selector:
    app: myapp

The cluster automatically assigns a unique external IPv4 address to this service. To see which IPv4 address has been assigned, go to the webconsole and navigate to "Applications -> Services". The IP is displayed in the field "External IP". Using the CLI is also possible: oc describe svc myapp.

Note

• Only IPv4 is supported, IPv6 is not available for this service yet
• Additional costs will apply for each external IP
