課程內容：各種k8s部署方式。包括minikube部署，kubeadm部署，kubeasz部署，rancher部署，k3s部署。包括開發測試環境部署k8s，和生產環境部署k8s。
介紹主要的k8s資源的使用配置和命令。包括configmap，pod，service，replicaset，namespace，deployment，daemonset，ingress，pv，pvc，sc，role，rolebinding，clusterrole，clusterrolebinding，secret，serviceaccount，statefulset，job，cronjob，poddisruptionbudget，podsecuritypolicy,networkpolicy,resourcequota，limitrange，endpoint，event，conponentstatus，node，apiservice，controllerrevision等。
詳細介紹helm命令，學習helm chart語法，編寫helm chart。深入分析各專案原始碼，學習編寫helm外掛程式
