I just installed Kubernetes and configure Master and Node, the basic things is okay.

I can deploy deployments, pods, services, But, there is an issue.

1 - After few Minutes Docker Containers Exit and restart, So I can not access this deployments from External

2 - Master Does not assign Node IP to Services.

I do not what codes should I share here.

this is Sample Log of pod :
