In my environment, autocompletion works for pods which have the longest name (253 characters). https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names

@whs-dot-hk Could you please try the above steps?

@superbrothers There is already auto-complete in linux? I was on a mac in my office (only choice). But, I use linux (ubuntu b4 now fedora) all of the time. Will have a try again soon.

[superbrothers]

Yes, there is. However autocompletion also works on macOS.

I am running into the same issue.
my environment is looks like:
```!bash

However, when I type
```!bash
$ kubectl get pods student-service
````
and then TAB, it doesn't autocomplete.

I am using a centos machine to run kubectl and executing the below instruction worked for me

yum install bash-completion

echo 'source <(kubectl completion bash)' >>~/.bashrc 
kubectl completion bash >/etc/bash_completion.d/kubectl 
echo "alias k=\'kubectl\'" >> ~/.bashrc 
echo 'complete -F __start_kubectl k' >>~/.bashrc 
source ~/.bashrc 

once it's completed, it should be able to get the response with TAB TAB
