本論文提出基於Kubernetes所開發之高可用飲水機平台服務，以解決現有使用Openstack架構平台所遇到的問題。現有Openstack平台是建構於單一伺服器上，並且在虛擬機上運行智慧飲水機服務，單一主節點雖然建置過程簡單，但故障時會造成整個服務中斷，需要數小時由人工修復;此外目前服務使用單套式架構，一個小更動都需要重新佈署整套系統，會降低開發的敏捷度。為解決以上問題，本論文利用Kuberntes高可用方案，在多個伺服器上同時建置多個主節點，在錯誤發生時自動恢復服務;本系統採取微服務架構，將服務拆解成專注於單一功能的微服務，佈署方面使用更輕量、攜帶性更高的Docker將服務容器化，將各個微服務獨立於容器上運行，增加開發的敏捷度。根據實測結果，新的系統在發現錯誤後可在數分鐘內自動恢復服務;新的系統中;軟體的更動只需重啟相對應的微服務即可。

This paper proposes a high availability water dispenser platform service based on Kubernetes in order to solve the problems encountered by the existing Openstack architecture platform. The existing Openstack platform is built on a single server. Run the smart water dispenser service on the virtual machine. The single master node is simple to build. When Failure ocur, it will cause the entire service to be interrupted. It takes hours to repair manually. In addition, the current service uses a monolithic architecture. A small change requires redeployment of the entire system, which reduces development agility. To solve the above problems, This paper utilizes Kuberntes high availability scheme to build multiple master nodes on multiple servers. when an error occurs, automatically recovery service. This system adopts microservice architecture. Applications are broken down into microservices focused on a single function. The deployment side uses lighter and more portable Docker to containerize the service. Run each microservice independently of the container, increasing development agility. According to the results, the new system can automatically recovery service within a few minutes after discovering errors. Software changes only need to restart the corresponding microservices.
