Zaka 25 zapitazo, Java idalowa m'mapulogalamu ambiri ndipo pamapeto pake idakhala imodzi mwamagawo omwe amamangidwira ma pulogalamu. Masiku ano, anthu ambiri ndi mabungwe omwe akhala okhulupirika kwa Java kwa zaka zambiri ali otanganidwa kusamuka kapena akuganiza zosamukira ku pulatifomu. kapena zotuluka zake monga kapena .
Tsoka ilo, Kubernetes ali ndi njira yophunzirira ndipo amayambitsa gawo lina logwira ntchito munjira yachitukuko yomwe opanga mapulogalamu a Java amazolowera. Lero tidzakuuzani momwe mungagwiritsire ntchito , kuti muchepetse magwiridwe antchito owonjezerawa okhudzana ndi Kubernetes ndi makontena, ndikuwonetsetsa kusamuka kopanda ululu kupita papulatifomu yamtambo ndikusunga chilengedwe cha Java chodziwika bwino. Komanso, tiwonetsa momwe tingatumizire mapulogalamu a Java pa nsanja ya OpenShift pogwiritsa ntchito pulogalamu ya OpenShift Maven.
Traditional Java Development Process
Ndondomeko yachitukuko cha chikhalidwe (Chithunzi 1) chimaphatikizapo kachidindo kameneka kakulemba, kenaka kupanga magawo otumizira monga mafayilo a JAR kapena WAR, ndiyeno kutumiza ndi kuyendetsa mafayilowa pa intaneti kapena seva yogwiritsira ntchito. Njira yayikulu yochitira izi ndikugwiritsa ntchito Maven kuchokera pamzere wolamula kapena kugwiritsa ntchito IDE ngati IntelliJ kapena Eclipse kuti mulembe ndikuyika mapulogalamu. Madivelopa amagwiritsidwa ntchito posintha ma code ndikuyesa zonse mosamalitsa asanapereke khodiyo ndikuyipereka kuti iziwongolera.
