kubectl exec into pod resulting in Unable to use a TTY error every time if run through automation

Question

i have a simple automation to exec into a kubernetes pod but it always results in the below error :-

kubectl exec -it my         


        

Answer 1

I got same error while creating a pod during Jenkins build:

$ oc run netshoot-pod --attach=true --restart=Never --rm -i --tty --image nicolaka/netshoot -- curl $IP

Unable to use a TTY - input is not a terminal or the right kind of file 
If you don't see a command prompt, try pressing enter. 
Error attaching, falling back to logs

Removing --tty / -t flag has fixed it.

Answer 2

I got it working using the below approach :-

kubectl exec -ti my-pod -c my-container -n my-namespace -- ls
