kubeconfig-cleanup's Introduction

kubeconfig-cleanup

About

Description

A kubectl plugin to clean up your kubeconfig file

Installation

Add kubeconfig-cleanup to your kubectl plugins directory. For more information about how plugins are loaded, please see the official documentation.

See Releases for the latest release matching your OS.

# Pick the right release, e.g. "v1.0.1 Linux x64"
$ export BINARY=kubeconfig-cleanup_1.0.1_Linux_x86_64.tar.gz

Then run install.sh by either cloning this repository or directly downloading the script.

Note: The script and plugin configuration is configured to use ~/.kube/plugins/kubeconfig-cleanup as the plugin and installation folder.

$ git clone https://github.com/ashleyschuett/kubeconfig-cleanup
$ cd kubeconfig-cleanup

# make sure the script it's executable
$ chmod +x install.sh
$ ./install.sh

Alternatively with curl:

$ curl -LO https://raw.githubusercontent.com/ashleyschuett/kubeconfig-cleanup/master/install.sh

# make sure the script it's executable
$ chmod +x install.sh
$ ./install.sh

Usage

Parse through kubeconfig in default directory

kubectl plugin kubeconfig-cleanup

Parse through kubeconfig at custom location

kubectl plugin kubeconfig-cleanup --kubeconfig /custom/kubeconfig/location

kubeconfig-cleanup's Issues

Illegal option -o pipefail

Hi,

When I run ./install.sh
I got this error:
./install.sh: 3: set: Illegal option -o pipefail

Distribute via krew?

https://github.com/GoogleContainerTools/krew

Krew makes it easy to package and distribute plugins for kubectl. This plugin would be also a great addition there.

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

Any suggestions? :-)

Support for kubectl v1.12.x+

Plugins were fundamentally changed in Kubernetes v1.12.x. This should be updated to work with the new plugin mechanism.

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

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)
The binary then has to be executable (chmod +x), otherwise error: fork/exec ./cleanup: permission denied
curl -LO -o does not work because -o has no effect here (just remove -O to fix)
mkdir should use option -p to not error out when plugins does not exist or when kubeconfig-cleanup already exists (e.g. upgrade)
the mv needs a target folder, i.e. mv cleanup plugin.yaml ~/.kube/plugins/kubeconfig-cleanup

Will file PR :)

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

I get this when trying to run:
