alpaca-prod 10.1.0.29:8080,10.1.0.30:8080,10.1.0.31:8080 59m

alpaca-prod の Deployment を削除

code:shell

$ kubectl delete deployments alpaca-prod

deployment.extensions "alpaca-prod" deleted

code:shell

$ kubectl get endpoints alpaca-prod --watch

alpaca-prod 10.1.0.31:8080 60m

alpaca-prod <none> 60m

再作成

code:shell

$ kubectl run alpaca-prod --image=kuard-amd64:1 --replicas=3 --port=8080 --labels="ver=1,app=alpaca,env=prod"

code:shell

$ kubectl get endpoints alpaca-prod --watch
