# Temp Kubernetes CI
A github action to create a kubernetes cluster in your CI VM for both linux & windows. Also has cmdline to copy and paste for other CI platforms.
## Usage
For linux you can reference [k3s environment variables](https://rancher.com/docs/k3s/latest/en/installation/install-options/how-to-flags/) on setting additional parameters
### GitHub Action
```yaml
- uses: knicknic/temp-kubernetes-ci@v1
```
### Other CI platform
Simply copy the below code snippet to get the latest version of the code
#### Linux
```bash
releaseVersion=$(curl --silent "https://api.github.com/repos/knicknic/temp-kubernetes-ci/releases/latest" | grep -Po '"tag_name": "\K.*?(?=")')
curl -sSL "https://github.com/KnicKnic/temp-kubernetes-ci/releases/download/$releaseVersion/linux.sh" | sh
```
#### Windows
```powershell
$request = [System.Net.WebRequest]::Create('https://github.com/KnicKnic/temp-kubernetes-ci/releases/latest')
$response = $request.GetResponse()
$tag = $response.ResponseUri.OriginalString.split('/')[-1]
$url = "https://github.com/KnicKnic/temp-kubernetes-ci/releases/download/$tag/windows.ps1"
$filePath = join-path $env:temp windows.ps1
Invoke-WebRequest -Uri $url -OutFile $filePath
& $filePath
```
## Why
When dealing with kubernetes you end up wanting to test against an actual kubernetes cluster.
1. Test your deployment files / helm charts actually deploy your app correctly
1. Test the controller you wrote against an actual kubernetes api server
## Source
| file | description |
|-------------|-------------------------------------------------------------------------------|
| index.js | determines what os and launches either linux.sh or windows.ps1 to install k3s |
| linux.sh | script to install k3s on linux |
| windows.ps1 | script to install k3s on windows |
## Tasks
1. ~~Figure out how to install k3s on linux and write a script to do so~~
1. ~~Figure out how to install k3s on windows and write a script to do so~~
1. ~~See https://github.com/rancher/k3s/issues/1618 for some info & a branch to start from~~
1. ~~Convert script to Github Action~~
1. ~~https://docs.github.com/en/actions/creating-actions/publishing-actions-in-github-marketplace~~
1. ~~Convert script to azure devops custom task - see https://docs.microsoft.com/en-us/azure/devops/extend/develop/integrate-build-task?view=azure-devops~~
1. ~~Find out if there is a market place for custom tasks like their is for github actions~~
1. Write a dynamic storage provisioner for windows folders (enables windows to fufill PVCs)
1. take https://github.com/KnicKnic/K8s-Storage-Plugins/tree/new_new and add a flexprovisioner & flexvolume that are just windows folders
1. take https://github.com/rancher/local-path-provisioner and get that to work with windows
1. This will also probably require csi proxy, which we could embed into k3s or run standalone
1. ~~Publish docs so generic CI platforms can use~~
1. ~~Write a load balancer for windows, equivalent of https://github.com/rancher/klipper-lb~~
1. Integrate linux with k3d to allow multiple linux nodes for a more realistic user scenario
