Kind: zsh: command not found: kubectl

[darshanparab]

What happened:
kubectl throws command not found error post cluster creation using kind create cluster

What you expected to happen:
Should be able to run kubectl

How to reproduce it (as minimally and precisely as possible):
Download and add kind to path as mentioned below

curl -Lo ./kind "https://github.com/kubernetes-sigs/kind/releases/download/v0.7.0/kind-$(uname)-amd64"
chmod +x ./kind
mv ./kind /some-dir-in-your-PATH/kind

Anything else we need to know?:
This is how I created the cluster

➜  ~ kind create cluster --name hello-world --config=.kube/config
Creating cluster "hello-world" ...
 ✓ Ensuring node image (kindest/node:v1.16.4) 🖼 
 ✓ Ensuring node image (kindest/node:v1.17.0) 🖼
 ✓ Preparing nodes 📦 📦  
 ✓ Writing configuration 📜 
 ✓ Starting control-plane 🕹️ 
 ✓ Installing CNI 🔌 
 ✓ Installing StorageClass 💾 
 ✓ Joining worker nodes 🚜 
Set kubectl context to "kind-hello-world"
You can now use your cluster with:

kubectl cluster-info --context kind-hello-world

Thanks for using kind! 😊
➜  ~ kubectl
zsh: command not found: kubectl

ah, you're going to need to install kubectl.

https://kubernetes.io/docs/tasks/tools/install-kubectl/

[darshanparab]

Thanks a lot @BenTheElder for pointing that out. That was silly of me. I thought, like minikube, this will also make kubectl available.

[BenTheElder]

imho it's bad that our documentation assumes kubectl is available though, we should update it with a reference to this.

@bentheelder Created an PR for this.

➜  ~ kubectl get nodes
The connection to the server localhost:8080 was refused - did you specify the right host or port?
➜  ~ kind             
/usr/local/bin/kind: 1: /usr/local/bin/kind: Not: not found

I installed kubectl and kind using the below instructions in documentation, I still get this error.

curl -Lo ./kind https://github.com/kubernetes-sigs/kind/releases/download/v0.7.0/kind-$(uname)-amd64
chmod +x ./kind
mv ./kind /some-dir-in-your-PATH/kind

Make sure that $(uname) actually evaluates to the operating system name.

I am using Windows with WSL 2. For me uname was resolving to "Linux" so the contents of the file kind was "Not Found"

❯ uname
Linux
❯ cat kind
Not Found%

So I used the following command to download kind:

curl -Lo ./kind https://github.com/kubernetes-sigs/kind/releases/download/v0.9.0/kind-linux-amd64

[BenTheElder]

we may need to upgrade the guide.
when it was written, github served files case-insensitively

Not sure if all the releases are lowercase, but a simple fix would be:

curl -Lo ./kind https://github.com/kubernetes-sigs/kind/releases/download/v0.7.0/kind-$(uname | tr '[:upper:]' '[:lower:]')-amd64
