From c2d10ed10fe2437547a7ad705ac9f76a736d27e3 Mon Sep 17 00:00:00 2001 From: garciadeblas Date: Fri, 21 Jan 2022 13:57:06 +0100 Subject: [PATCH] Fixed installation issue with kube-flannel.yml The installation of the local K8s cluster fails when kube-flannel.yml is not found in the temp folder. The error that we see in the installation is "error reading [/tmp/flannel.*****]: recognized file extensions are [.json .yaml .yml]" This commit updates the function deploy_cni_provider to remove the silent output when getting kube-flannel.yml. In addition, it adds several retries on error. Finally, the error message has been modified to be more explicit about the error.
