Why is my docker run success and k8s fails to take the proxies
My Docker container runs by executing a docker run. Where as during my container boots it executes my rest api call under the Spring boot API instance before it get get started in a specfic port.
During the API call it requires a proxy to bypass and access the endpoint, and load all my property details.
Where as i am getting is happened when i run it using the docker run. But fails when the same is ran under kubernetes.

Am i missing out something here. Still wondering how my docker run is success and deployments fail in k8s
You have to untaint the master so you can run pods. Execute following command:
$ kubectl taint nodes kmaster node-role.kubernetes.io/master-
Take a look: single-node-kubernetes-setup.
