From b6498a0ce5468f00e08da521cdfa082470699906 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Fabiano=20Fid=C3=AAncio?= Date: Thu, 10 Nov 2022 11:10:19 +0100 Subject: [PATCH] quickstart: Add a note about QEMU limitation with Kind / Minikube MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It's a known limitation that QEMU based runtime classes will not work with Kind or Minikube, leading to: ``` Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal Scheduled 42s default-scheduler Successfully assigned default/nginx-kata-qemu to minikube Warning FailedCreatePodSandBox 9s kubelet Failed to create pod sandbox: rpc error: code = Unknown desc = failed to create containerd task: failed to create shim task: Failed to Check if grpc server is working: rpc error: code = DeadlineExceeded desc = timed out connecting to vsock 3189232285:1024: unknown ``` This needs further debug in order to get to the root cause of the issue, and potentially to a fix. However, for now, we should make sure that we document such limitation. One issue already reported about this is https://github.com/confidential-containers/operator/issues/124, and that's also been observed by Pradipta during the early tests of v0.1.0.
