Latest versions are not working about k8s

@ozbillwang This is a issue, I just execed inside the container

and found iam-authenticator is broken.

It broke my CI :(

try now

Hmm could be, I thought the same too, I was thinking of trying alternative, directly from github like:

latest_aws_iam_auth=$(curl https://github.com/kubernetes-sigs/aws-iam-authenticator/releases/latest | sed -r 's/.*http.*v(.*)">.*/\1/')
AWS_IAM_AUTH_VERSION_URL=https://github.com/kubernetes-sigs/aws-iam-authenticator/releases/download/v${latest_aws_iam_auth}/aws-iam-authenticator_${latest_aws_iam_auth}_linux_amd64

I used to get the latest release from github, but I found they are different.

seems you run something in AWS EKS, please check your setting in it. it blocked your external access to github.com.

Second, check if you can connect to kubernetes cluster:

kubectl get nodes
kubectl get all --all-namespaces

This is not the image problem, you need figure it out by yourself. Otherwise ask for help by search google or stackoverflow.

Hey @ozbillwang, I think you could just rebuild it once again on travis, build.sh its working with new iam binary for me in local.

This job is weird though: https://travis-ci.org/github/alpine-docker/k8s/jobs/718664972

I wonder why build.sh pulled this url: https://amazon-eks.s3.us-west-2.amazonaws.com/1.17.9/2020-07-08/bin/linux/amd64/aws-iam-authenticator

New build worked from me @ozbillwang 👍

Edit:
Just an idea 🤔 ; would be better if these tools be verified at the end of Dockerfile with simple version command like:

[ozbillwang]

the aws-iam-auth url is coming from this document:

https://docs.aws.amazon.com/eks/latest/userguide/install-aws-iam-authenticator.html

AWS doesn't share us the go through permission that we can't know what's the latest version from above url

https://amazon-eks.s3.us-west-2.amazonaws.com/1.17.9/2020-08-04/bin/linux/amd64/aws-iam-authenticator

I used some scripts to catch the keyword about 1.17.9/2020-08-04, but seems aws developers are keep changing the html format. The build.sh is failed to get the latest version of "aws-iam-auth"
