Adding pod dependency to kubernetes.For example if a web server needs to a database it should watch and if database shut , down also web service must shut down because of not wasting resources.
For installing you should first build docker image
docker build -t anilkuscu/dependon .
docker push anilkuscu/dependon
After push apply the yaml file on kubernetes.
kubectl apply -f dependon.yaml
You should edit dependon.yaml file as your will.It includes a example dependon crd on the last section.
