Question / Where do you need Help?

Scope of your Question

• Is your question related to a specific version of k3d (or k3s)?
  • Please paste the output of k3d version
    k3d version v5.4.6
    k3s version v1.24.4-k3s1 (default)
    

install was successful but there is there is some port issue can any help[ to figure this?

[iwilltry42]

How did you install the cluster?
/path/to/kubeconfig/file looks like a placeholder? Or is that the real value of your KUBECONFIG environment variable?

But also 8080 would be an uncommon choice of port-mapping for the API and definitely not automatically chosen by k3d.

[souravsk]

Previously I was using minikube and it's still installed but it was too have for my laptop it's an old laptop.
So it gets to know about k3d I visited the website and follow the instructions.
Step 1:- wget -q -O - https://raw.githubusercontent.com/k3d-io/k3d/main/install.sh | bash
Step 2:- k3d cluster create mycluster
Step 3:- kubectl get nodes
but in this step i get that error

[iwilltry42]

That's very weird.
What's the value of your KUBECONFIG environment variable?
Also, can you maybe repeat Step 2 with the --trace flag and paste the output here?

[souravsk]

when i use the command env

sovu@sourav-pc:~$ k3d cluster create mycluster --trace

[iwilltry42]

There you go:

WARN[0064] failed to create output directory '/path/to/kubeconfig': mkdir /path: permission denied

When did you set the KUBECONFIG variable to that invalid path though? 🤔
Maybe unset that variable or set it to an actual path. The kubectl default is $HOME/.kube/config.

[souravsk]

so how do i set the path in the right place

[iwilltry42]

Well.. unset the environment variable or set it to some path that actually exists, e.g. unset KUBECONFIG or export KUBECONFIG=$HOME/.kube/config.
But it would be good for you to find out what/why this was set to an artificial non-existent path.
