I created cluster by using eksctl.

@yuwenhui Can you build this docker file on you workstation?

[maxvint]

This problem was caused by the EKS config. I was created my EKS cluster by eksctl firstly until i saw this: enable-docker-bridge, eksctl disable the docker bridge so the pods couldn't connect external network.

Finally i resolved this problem by recreated EKS cluster use Terrform, and use this module terraform-aws-eks.

By the way, i found that Terrform is an very awesome tool to manage cluster and do some other things.
