Create user defined "NodePort" services per pod
This feature will give the user the ability to create user defined "NodePort" services per pod, a part from the default SSH port created, by default, for each pod created. Example of Kubernetes yaml definition: apiVersion: v1 kind: Servicemeta data: name: pod-1-service-nodeport spec: type: NodePort ports: - name: web port: 80 targetPort: 8888 nodePort: 33333 clusterIP: 10.254.0.8 selector: app: pod-1 Example of Yardstick test case definition: context: type: Kubernetes servers: host: containers: - image: ... securityContext: allowPrivilegeEscalation: false - image: ... node_ports: - port: <port number> # Mandatory name: <port name> # Optional targetPort: <port name> # Optional, default: targetPort=port nodePort: <port number> # Optional, assigned by Kubernetes Kubernetes service, type "NodePort" [1] [1] https://kubernetes.io/docs/concepts/services-networking/service/#type-nodeport JIRA: YARDSTICK-1181 Change-Id: Ia7730e4569d5526d573402a98c27d55c5c82cdef Signed-off-by: Rodolfo Alonso Hernandez <rodolfo.alonso.hernandez@intel.com>
