But it also means that when writing code, the paths for reading the relevant interface files are different, so compatibility handling is required.微信公众号KubernetesUpgradeOperationscgroupLearningNodesResource IsolationTroubleshootingKubelethttps://www.chenshaowen.com/en/blog/add-windows-node-for-k8s.htmlSat, 13 Jun 2020 00:00:00 +0000Sat, 13 Jun 2020 00:00:00 +0000https://www.chenshaowen.com/en/blog/add-windows-node-for-k8s.htmlHere a Windows node is used mainly as a Worker, while the Master control plane stays on Linux. 1.
