作者主要從事數(shù)據(jù)中心網(wǎng)絡(luò)解決方案的研發(fā)與部署，技術(shù)方向包括云計算、軟件定義網(wǎng)絡(luò)（SDN）、網(wǎng)絡(luò)安全等，是國內(nèi)較早從事 SDN 和網(wǎng)絡(luò)虛擬化相關(guān)技術(shù)的推廣者，同時也是 Docke開源社區(qū)的發(fā)起人之一。
本書作者一直在Google和其他公司從事Kubernetes方面的工作，為我們解釋了該系統(tǒng)如何融入分布式應(yīng)用程序的生命周期之中的。你將學(xué)習(xí)如何使用各種工具和API來實現(xiàn)可擴展分布式系統(tǒng)管理的自動化，無論該系統(tǒng)用于在線服務(wù)、機器學(xué)習(xí)應(yīng)用程序，還是Raspberry Pi計算機群集。本書的主要內(nèi)容有：探索Kubernetes所面臨的分布式系統(tǒng)挑戰(zhàn)。使用Docker等容器進行容器化應(yīng)用開發(fā)。使用docker鏡像格式和容器運行時在Kubernetes上創(chuàng)建和運行容器。探索在生產(chǎn)中運行應(yīng)用程序所必需的專門對象。在無需停機或無差錯情況下可靠地推出新的軟件版本。舉例說明如何在Kubernetes中開發(fā)和部署真實應(yīng)用程序。
