I've been using kubectl in Cygwin on Windows 10 for quite a while, to communicate to our in-house k8s clusters. I often use "kubectl exec" to open a shell in a container or directly execute a shell command. This has worked perfectly fine for a long time.
A couple of days ago, I discovered that all of these attempts were failing with "Upgrade request required". I hadn't upgraded kubectl or Cygwin in quite a while. I doubt our clusters had a k8s upgrade, but it's entirely possible. A colleague of mine has a very similar desktop configuration (Windows 10, Cygwin), and he's not seeing this symptom. I noticed that when I ran "kubectl exec" with max verbosity, it shows the resulting "curl" command that it runs. I tried that resulting command, and it results in the same response. I then tried updating my Cygwin tools and retesting, no change. I then took the entire resulting "kubectl exec" command line and ran it in a "cmd" shell. No problem at all. No error. I know I haven't provided much useful information yet. I wanted to get an initial response before I started providing those diagnostics. Is there a clear issue here that I'm not aware of? -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
