Running kubectl returns "TLS handshake timeout"

I'm on a Mac and everything has gone well except I started getting the following error when executing various kubectl commands. After multiple attempts the command may execute successfully. But now I'm to the point after 10 minutes I can't get past this error. Any help is appreciated.

kubectl -n cass-operator describe cassdc dc1
Unable to connect to the server: net/http: TLS handshake timeout
kubectl -n cass-operator exec -it cluster1-dc1-default-sts-0 -- /bin/bash
Unable to connect to the server: net/http: TLS handshake timeout

Hi @sandy.davis_63587,

this is likely due to insufficient resources. Try to increase the resource limits in your Docker preferences.

See this Stackoverflow post for more info, where a user reported similar issues.

I hope this helps to overcome this issue.

To add to Bettina's answer, we have previously advised during the workshops that you will run into issues if you don't provision sufficient resources on your machine.

We recommend that you allocate the following to Docker:

  • 4 cores
  • 4GB of RAM (8GB preferred)

These minimum settings should allow you to complete the exercises for the workshops. Cheers!
