Make WSL use Rancher Desktop kubeconfig

 

✅ 1. First: Check the kubeconfig Rancher Desktop injects into Windows

Rancher Desktop ALWAYS writes a kubeconfig to this standard location:

👉 C:\Users\<your-user>\.kube\config

Check it:

PowerShell:

dir $HOME\.kube

If you see a file named config, then that is the correct kubeconfig.

eg: 

Directory: C:\Users\admin\.kube

Mode                 LastWriteTime         Length Name

----                 -------------         ------ ----

d-----        22/11/2024  10:12 AM                cache
-a----        06/12/2025   8:58 AM           6054 config

Inside WSL run:

mkdir -p ~/.kube
ln -s /mnt/c/Users/admin/.kube/config ~/.kube/config

Now WSL and PowerShell use the same Kubernetes context.

Create aliases for convenience

Inside WSL, so you don’t have to type .exe:

echo "alias kubectl='kubectl.exe'" >> ~/.bashrc
echo "alias helm='helm.exe'" >> ~/.bashrc
source ~/.bashrc

Now in WSL you can run:

kubectl get nodes
helm list -A

Exactly like in PowerShell.

Push containe to GHCR

Command for push to GHCR

1. Log in to GHCR

Use Docker CLI to authenticate to GitHub Container Registry:

echo YOUR_GITHUB_PERSONAL_ACCESS_TOKEN | docker login ghcr.io -u YOUR_GITHUB_USERNAME --password-stdin

 

Make sure your PAT (Personal Access Token) has the write:packages and read:packages scopes.

2. Tag your Docker image

Assuming your image is named my-app:latest, tag it for GHCR:

docker tag my-app:latest ghcr.io/YOUR_GITHUB_USERNAME/my-app:latest

Replace YOUR_GITHUB_USERNAME with your actual GitHub username (or org name).

You can also add versions/tags as needed.

3. Push the image

Push the tagged image to GHCR:

docker push ghcr.io/YOUR_GITHUB_USERNAME/my-app:latest

4. Verify on GitHub

Go to your GitHub profile or organization, then:

• Navigate to Packages.

• You should see your pushed Docker image there.

Docker error : The network name cannot be found.

 If u get this error

deploying WSL2 distributions ensuring main distro is deployed: checking if main distro is up to date: checking main distro bootstrap version: getting main distro bootstrap version: open \\wsl$\docker-desktop\etc\wsl_bootstrap_version: The network name cannot be found. checking if isocache exists: CreateFile \\wsl$\docker-desktop-data\isocache\: The network name cannot be found.

 

Try the following to troubleshoot:

1. Stop Docker Desktop
2. Run the following command in your terminal wsl --unregister docker-desktop
3. Run Docker Desktop again (Will recreate the distro)

Note: I also start my Docker Desktop as Administrator each time, so you probably need to run your terminal/Powershell as Administrator like I did.

Enable ingress

https://blog.raulnq.com/testing-the-nginx-ingress-controller-locally-docker-desktop

 

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update
helm install nginx-ingress ingress-nginx/ingress-nginx

Run kubectl get ingressclass and kubectl get services to check the installation:

First Deployment 

kubectl create deployment web --image=gcr.io/google-samples/hello-app:1.0

kubectl expose deployment web --type=NodePort --port=8080 

 

Second Deployment  

kubectl create deployment web2 --image=gcr.io/google-samples/hello-app:2.0
kubectl expose deployment web2 --port=8080 --type=NodePort

                port:
                  number: 8080

kubectl apply -f example-ingress.yaml 

kubectl get ingress

minikube up cluster

 

Start your cluster

 

 

minikube start

kubectl get po -A

minikube kubectl -- get po -A
 

minikube dashboard

start kube 

kubectl create deployment hello-minikube --image=kicbase/echo-server:1.0
kubectl expose deployment hello-minikube --type=NodePort --port=8080
 

kubectl get services hello-minikube

minikube service hello-minikube

kubectl port-forward service/hello-minikube 7080:8080


 

Install swoole on window

 

Not directly, but with Docker and WSL (Windows Subsystem for Linux).

1. Install Docker (https://www.docker.com/products/docker-desktop)
2. Setup WSL

Open PowerShell as Administrator and run

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

Updating/Install the WSL 2 Linux kernel (https://docs.microsoft.com/en-us/windows/wsl/wsl2-kernel)

3. Enable "Enable the experimental WSL 2 based engine" in Docker (General)
4. Build the Docker container

IMPORTANT! Don't use a path with spacebars like:

• C:\Users\ {FIRSTNAME}[SPACEBAR]{LASTNAME}\Desktop\docker)

Create a folder (D:\docker) and create with an Editor the Dockerfile (D:\docker\Dockerfile)

FROM php:7.4.2-cli

RUN apt-get update && apt-get install vim -y && \
    apt-get install openssl -y && \
    apt-get install libssl-dev -y && \
    apt-get install wget -y && \
    apt-get install git -y && \
    apt-get install procps -y && \
    apt-get install htop -y

RUN cd /tmp && git clone https://github.com/swoole/swoole-src.git && \
    cd swoole-src && \
    git checkout v4.4.15 && \
    phpize  && \
    ./configure  --enable-openssl && \
    make && make install

RUN touch /usr/local/etc/php/conf.d/swoole.ini && \
    echo 'extension=swoole.so' > /usr/local/etc/php/conf.d/swoole.ini

RUN wget -O /usr/local/bin/dumb-init https://github.com/Yelp/dumb-init/releases/download/v1.2.2/dumb-init_1.2.2_amd64
RUN chmod +x /usr/local/bin/dumb-init

RUN apt-get autoremove -y && rm -rf /var/lib/apt/lists/*

ENTRYPOINT ["/usr/local/bin/dumb-init", "--", "php"]

Open PowerShell navigate to your folder (D:\docker) to build the DockerImage

docker build -f ./Dockerfile -t swoole-php .

5. Add your swoole source code

As an example (D:\docker\server.php)

<?php
$http = new Swoole\HTTP\Server("0.0.0.0", 9501);

$http->on('start', function ($server) {
    echo "Swoole http server is started at http://127.0.0.1:9501\n";
});

$http->on('request', function ($request, $response) {
    $response->header("Content-Type", "text/plain");
    $response->end("Hello World\n");
});

$http->start();
?>

6. Start your swoole http server with the PowerShell

docker run --rm -p 9501:9501 -v D:/docker/:/app -w /app swoole-php server.php

Gradle does not have execution permission.

How to solve the problem

run this command in flutter android directory

chmod a+rx gradlew
