Instruction to check service external IP  feature/capability

1. 'Pool' mode

             1.1 Set ‘external_svc_subnet’ in /etc/kuryr/kuryr.conf ,

[neutron_defaults]
external_svc_subnet=  external_subnet_id

 In devstack environment can be set to ‘public-subnet’ id.


            1.2 Create k8s service/deployment  as follows :
"
kubectl run --image=celebdor/kuryr-demo kuryr-demo901
 kubectl scale deploy/kuryr-demo901   --replicas=2
 kubectl expose deploy/kuryr-demo901 --port 80 --target-port 8080 --type=LoadBalancer
"

            1.3 Expected results
            1.3.1 K8s service status :

               EXTERNAL-IP field set for the relevant service

[stack@yossib devstack]$ kubectl get svc
NAME            CLUSTER-IP   EXTERNAL-IP   PORT(S)        AGE
kubernetes      10.0.0.129          <none>        443/TCP        1d
kuryr-demo901   10.0.0.142      172.24.4.2    80:31644/TCP   58m

            1.3.2 LbaaS can be accessed using EXTERNAL-IP

[stack@yossib devstack]$ curl 172.24.4.2
kuryr-demo901-2349527529-m2q5p: HELLO, I AM ALIVE!!!
[stack@yossib devstack]$


2. User specified external IP
    2.1 create floating IP  (let’s say floating IP is 172.24.4.13)
    2.2  Create k8s service/deployment  as follows :
"
kubectl run --image=celebdor/kuryr-demo kuryr-demo551
 kubectl scale deploy/kuryr-demo551   --replicas=2
 kubectl expose deploy/kuryr-demo551 --port 80 --target-port 8080 --type=LoadBalancer --load-balancer-ip=172.24.4.13
"

2.3 Expected results

 2.3.1 K8s service status :
               EXTERNAL-IP field set for the relevant service
[stack@yossib devstack]$ kubectl get svc
NAME            CLUSTER-IP   EXTERNAL-IP   PORT(S)        AGE
kubernetes      10.0.0.129   <none>        443/TCP        1d
kuryr-demo551   10.0.0.177   172.24.4.13   80:31353/TCP   25s
[stack@yossib devstack]$

2.3.2 LbaaS can be accessed using EXTERNAL-IP

[stack@yossib devstack]$ curl 172.24.4.13
kuryr-demo551-2553868779-rqckp: HELLO, I AM ALIVE!!!
[stack@yossib devstack]$
