https://docs.rancherdesktop.io/how-to-guides/hello-world-example/ I followed the above document and got stuck at "Deploy to Kubernetes". There seems to be a connection error, how do I solve it?

kubectl version

If you set

--image-pull-policy=Never

then how is the image going to be pulled to your kubernetes (Rancher Desktop) cluster?

✅ 1

Did you push the image into the cluster yourself?

may be yes. ^^;

How can I push the image to my cluster(rancher-desktop)?

Okay. Were you following the

nerdctl

or the

docker

instructions?

docker

Okay. Just doing the

docker build --tag...

should have made the image available to your cluster. Let me just replicate the process...

docker build --tag nginx-helloworld:latest .

Dockerfile FROM nginx:alpine COPY . /usr/share/nginx/html index.html <h1>Hello World from NGINX!!</h1>

I did as described, but why doesn't it work?

Can you do

kubectl config get-contexts

just to check your kubectl config is pointing to your local Rancher Desktop context.

Copy code

$ kubectl config get-contexts 
CURRENT   NAME                             CLUSTER            AUTHINFO           NAMESPACE
*         rancher-desktop                  rancher-desktop    rancher-desktop

The instructions work exactly as expected for me...

Copy code

$ kubectl get pods
NAME          READY   STATUS    RESTARTS   AGE
hello-world   1/1     Running   0          52s

Are you sure that Rancher Desktop is configured for

dockerd (moby)

Thanks a lot

I succeeded It worked when I deleted docker-desktop and tried again.

Thank you very much!!
