Tennis Games Duo's

Lists all possible game combinations for the specified men and women.

Takes into account that each team should play every other team and no duplicate matches should occur

Only supports max 4 players per side.

Future versions may do this lazily based on amount of games requested and allow for larger max size

Examples

http://localhost:8080/games?games=10&courts=2&interval=WEEKS&men=1&men=2&men=3&men=4&women=A&women=B&women=C&women=D

Install nginx-ingress

Verify installation

k get all --namespace ingress-nginx --watch

Configure static IP for nginx controller

Without loadBalancerIp specified (type=LoadBalancer will reserve address):

k apply -f nginx-service.yaml
k get svc ingress-nginx --namespace ingress-nginx --watch

When assigned, promote to static:

kubectl patch svc ingress-nginx -p '{"spec": {"loadBalancerIP": "35.205.70.155"}}' --namespace ingress-nginx
gcloud compute addresses create ingress-nginx-ip --addresses 35.205.70.155 --region europe-west1  
gcloud compute addresses describe ingress-nginx-ip --region europe-west1 --format 'value(address)'

Update swagger.yaml with IP so cloud endpoints dns know about it

cd app/src/main/resources && gcloud endpoints services deploy swagger.yaml

Install Tennis games service on cluster

k apply -f kubernetes.yaml

Wait for ingress

k get ing tennis-games-ingress --watch
k describe ing tennis-games-ingress
