====================================================
Trim 📏 your KUBECONFIG automatically.
[](https://github.com/sponsors/alexellis) [](https://github.com/alexellis/kubetrim/actions/workflows/build.yml)
[](https://opensource.org/licenses/MIT)
kubetrim tidies up old and broken cluster and context entries from your kubeconfig file.
It works like this:
1) Loads the config specified by KUBECONFIG
2) Tries to connect to each
3) Writes a new file with only the ones that it could access
Q&A:
* What if I like doing things the long way?
You can combine `kubectl config get-clusters` with `kubectl config use-context` and `kubectl get nodes`, followed by `kubectl config delete-cluster` and `kubectl config delete-context` for each. `kubectx -d` will remove a context, but leaves the cluster in your kubeconfig file, so requires additional steps.
* Doesn't [my favourite tool] have an option to do this?
Feel free to use your favourite tool instead. kubetrim is a memorable name, and a simple tool that just does one job, similar to `kubectx`
* What if I want to keep a cluster that is unreachable?
You can add each context name to the keep file at `~/.local/kubetrim/keep.txt`. You can also use comments in this file by prefixing the comment with `# Needs work VPN etc`
* What if my cluster is valid, but kubetrim cannot detect it?
Open an issue, and we can look at adding support for your use-case.
* `kubetrim` is great, how can I support you?
Have a look at [arkade](https://github.com/alexellis/arkade) and [k3sup](https://github.com/alexellis/k3sup), you may like those too. You can also [sponsor me via GitHub](https://github.com/sponsors/alexellis).
* How can I run kubetrim daily?
Create a crontab with the following expression: `0 0 * * * kubetrim`
* Can I run kubetrim every time I open a terminal?
Yes, you can add `kubetrim &` to your `.bashrc`, `.bash_profile` or `.zshrc` file, which will run in the background, and not slow down your terminal session from starting up.
* What if my WiFi is down and I run this tool?
If all clusters show as unavailable, kubetrim will not delete any clusters, in this case add `--force` to the command.
## Usage
```bash
$ kubectx
default
do-lon1-openfaas-cluster
kind-2
kind-ingress
$ kubetrim
kubetrim (dev) by Alex Ellis
Loaded: /home/alex/.kube/config. Checking..
- kind-2: ✅
- kind-ingress: ❌ - (failed to connect to cluster: Get "https://127.0.0.1:40349/api/v1/nodes": dial tcp 127.0.0.1:40349: connect: connection refused)
- default: ✅
- do-lon1-openfaas-cluster: ❌ - (failed to connect to cluster: Get "https://da39a3ee5e6b4b0d3255bfef95601890afd80709.k8s.ondigitalocean.co.uk/api/v1/nodes": dial tcp: lookup da39a3ee5e6b4b0d3255bfef95601890afd80709.k8s.ondigitalocean.co.uk on 127.0.0.53:53: no such host)
Updated: /home/alex/.kube/config (in 364ms).
$ kubectx
default
kind-2
```
Try out kubetrim without writing changes to the kubeconfig file:
```bash
$ kubetrim --write=false
```
Use a different kubeconfig file:
```bash
$ KUBECONFIG=$HOME/.kube/config.bak kubetrim
```
What if the Internet is unavailable, and all clusters report as unavailable?
```bash
# Take down WiFi/Ethernet
$ kubetrim
No contexts are working, the Internet may be down, use --force to delete all contexts anyway.
# Force the deletion, even if all clusters are unavailable.
$ kubetrim --force
```
## Installation
Getting `kubetrim` with arkade:
```bash
curl -sfLS https://get.arkade.dev | sh
arkade get kubetrim
```
