kubeconfig-cleanup's Issues

Error on Ubuntu 16.04

I just discovered this project and am keen to give it a try. I followed the instructions in the README to clone the repo into the .kube/plugins/kubeconfig-cleanup folder but I get the following error when I try to run it:

 $ kubectl plugin kubeconfig-cleanup
error: fork/exec ./cleanup: exec format error

I also tried to grab the source with go get but get an error with that too:

# github.com/ashleyschuett/kubeconfig-cleanup/pkg/config
pkg/config/config.go:164:52: cannot use m.getContextsUser(context) (type *"k8s.io/client-go/tools/clientcmd/api".AuthInfo) as type *"k8s.io/kubernetes/vendor/k8s.io/client-go/tools/clientcmd/api".AuthInfo in assignment
pkg/config/config.go:166:118: cannot use "k8s.io/apimachinery/pkg/apis/meta/v1".GetOptions literal (type "k8s.io/apimachinery/pkg/apis/meta/v1".GetOptions) as type "k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/apis/meta/v1".GetOptions in argument to client.CoreV1().ConfigMaps("k8s.io/apimachinery/pkg/apis/meta/v1".NamespacePublic).Get

Any suggestions? :-)

Doesn't work with GCP auth provider (GKE contexts)

I get this when trying to run:

Testing context's 'gke-skeenan-eaa3d8e68f' cluster...
error converting to clientset: failed to create API client: No Auth Provider found for name "gcp"
Remove 'gke-skeenan-eaa3d8e68f' from context (Y/n)? panic: reflect: call of reflect.Value.Type on zero Value

Panic: runtime error: invalid memory address or nil pointer dereference

Hi,

Getting a panic directly after involvement.

$ k plugin kubeconfig-cleanup

New Installation breaks tool

Hi Ashley,

Thx for switching to goreleaser :)

I found some issues with the new installation procedure:

export BINARY=kubeconfig-cleanup_1.0.1_Linux_x86_64.tar.gz
curl -LO -o cleanup https://github.com/ashleyschuett/kubeconfig-cleanup/releases/download/v1.0.1/$BINARY && \
curl -LO https://raw.githubusercontent.com/ashleyschuett/kubeconfig-cleanup/v1.0.1/plugin.yaml && \
mkdir ~/.kube/plugins/kubeconfig-cleanup && mv cleanup plugin.yaml
  1. The BINARY is a tgz, meaning that it must be extracted first and not just moved (will error out with error: fork/exec ./cleanup: exec format error)
  2. The binary then has to be executable (chmod +x), otherwise error: fork/exec ./cleanup: permission denied
  3. curl -LO -o does not work because -o has no effect here (just remove -O to fix)
  4. mkdir should use option -p to not error out when plugins does not exist or when kubeconfig-cleanup already exists (e.g. upgrade)
  5. the mv needs a target folder, i.e. mv cleanup plugin.yaml ~/.kube/plugins/kubeconfig-cleanup

Will file PR :)
