25 sano ka hor, Java waxa ay gashay qaybta guud ee barnaamijyada oo aakhirkii waxa ay noqotay mid ka mid ah curiyayaasha udub dhexaadka u ah taas oo xidhmooyin codsiyo ah lagu dhisay. Maanta, si kastaba ha ahaatee, dad badan iyo ururo badan oo daacad u ahaa Java sannado badan ayaa ku mashquulsan inay u guuraan ama u guuraan goobta. ama asalkiisa sida ama .
Nasiib darro, Kubernetes waxay leedahay qalooc waxbarasho oo qotodheer waxayna soo bandhigaysaa lakab kale oo hawlgelin ah oo ku saabsan habka horumarinta ee barnaamijyada Java-ga ay caadeysteen. Maanta waxaan kuu sheegi doonaa sida loo isticmaalo , si loo fududeeyo hawlgaladan dheeraadka ah ee la xidhiidha Kubernetes iyo weelasha, iyo in la hubiyo u guuritaanka aan xanuunka lahayn ee goobta daruuraha iyadoo la ilaalinayo nidaamka deegaanka Java ee la yaqaan. Intaa waxaa dheer, waxaan ku tusi doonaa sida loo geeyo codsiyada Java goobta OpenShift iyadoo la adeegsanayo plugin OpenShift Maven.
Habka Horumarinta Java ee Dhaqanka
Habka horumarinta dhaqanka (Jaantuska 1) waxay ku lug leedahay soo-saare kood qorista, ka dib abuurista cutubyo geynta qaabka JAR ama faylasha WAR, ka dibna geynta iyo socodsiinta faylashan shabakada ama server-ka codsiga. Habka ugu weyn ee tan loo sameeyo waa in la isticmaalo Maven oo ka socda khadka taliska ama isticmaal IDE sida IntelliJ ama Eclipse si aad u codeeeyso oo aad u xirto codsiyada. Horumariyayaashu waxa loo isticmaalaa in ay wax ka beddelaan koodka oo ay si fiican u tijaabiyaan wax kasta ka hor inta aanay samayn koodka oo ay u soo gudbiyaan xakamaynta nooca.
Bariis 1. Habka horumarinta Java ee dhaqanka.
Habka Horumarinta Java ee Cloud
Markaad u guurto codsiyada daruuraha, Kubernetes iyo . Sidaa darteed, hadda horumariyuhu wuxuu u baahan yahay inuu ku xidho codsiyada Java oo samee muuqaalada Kubernetes ee qeexaya sawiradan. Muujintan ayaa markaa lagu dabaqaa server-ka wax soo saarka ee ku shaqeeya Kubernetes. Dhanka kale, Kubernetes waxay sawiradan ka soo qaadaa diiwaanka waxayna geysaa codsiyada iyadoo loo eegayo qaabeynta aan ku qornay muujinta, kuwaas oo badanaa ah faylasha YAML.
Metamorphosis ee geedi socodka horumarinta Java ee soo jireenka ah ee u gudubka daruurta ayaa lagu muujiyay shaxanka. 2.

U haajiridda Kubernetes waxay ku darsataa lakab kale oo hawlgelineed geeddi-socodka horumarka, horumariyayaal badanina way ka walaacsan yihiin sababta oo ah waxay rabaan inay diiradda saaraan shaqadooda asaasiga ah - macquulka codsiga-halkii sidii loo geyn lahaa. Waana meesha ay ka soo gasho ciyaarta. , kaas oo u ogolaanaya horumariyayaasha inay isticmaalaan maktabadahooda iyo plugins ( wada jir ama ) in si dadaal la'aan ah loo sameeyo weel iyo hawlgallo la xiriira Kubernetes iyadoo la raacayo jaantuska Jaantuska. 2.
Inta ka hartay maqaalkan, waxaan ku tusi doonaa sida loo fududeeyo habka horumarinta Java ee deegaanka Kubernetes adigoo isticmaalaya Eclipse JKube oo wata Kubernetes Maven Plugin.

Hadda aan eegno tusaalooyinka isticmaalka Eclipse JKube iyo Kubernetes Maven Plugin marka la shaqeynayo codsiyada.
Gelitaanka Codsiga Java ee Kubernetes Isticmaalka Eclipse JKube
Tusaalahan waxa aanu ku shubi doonaa arji Java fudud koox iyadoo la isticmaalayo Eclipse JKube. Adigoo adeegsanayna Kubernetes Maven Plugin, waxaan dejin karnaa cabbirada geynta anagoon qorin wax qaabayn ah.

Tallaabada 1. Soo deji Kubernetes Maven Plugin
Kubernetes Maven Plugin waxa uu ku yaalaa kaydka . Si aad u isticmaasho Eclipse JKube waxaad u baahan tahay inaad kubernetes Maven Plugin ku darto pom.xml kaaga tiirsanaan ahaan:
<plugin>
<groupId>org.eclipse.jkube</groupId>
<artifactId>kubernetes-maven-plugin</artifactId>
<version>${jkube.version}</version>
</plugin>
Haddii OpenShift loo isticmaalo halkii laga isticmaali lahaa Kubernetes saafi ah, markaa pom.xml waxaa loo habeeyey sida soo socota:
<plugin>
<groupId>org.eclipse.jkube</groupId>
<artifactId>openshift-maven-plugin</artifactId>
<version>${jkube.version}</version>
</plugin>
Tallaabada 2. Dhis sawirka docker
Faylka codsiga ee JAR waxaa lagu dhisi karaa amarka xirmada mvn, ka dibna mvn goal task k8s:build waxaa loo isticmaali karaa in lagu dhiso sawirka docker ee codsiga. Ogsoonow in aanu ka gudubnay magaca sawirka caadiga ah ee hantidan:
<jkube.generator.name>docker.io/rohankanojia/random-generator:${project.version}</jkube.generator.name>
Kahor intaadan dhisin sawirka, waxaad u baahan tahay inaad hubiso in docker daemon si sax ah loo qaawiyo. Tan waxaa lagu samayn karaa amarka soo socda:
$ eval $(minikube docker-env)
Kadibna waxaan galeynaa mvn k8s: Build Command, waana tan waxa aan ku arki doonno shaashadda marka la dhisayo sawirka docker-ka iyadoo la adeegsanayo hawsha dhismaha Eclipse JKube:

Ka dib markaad dirto sawirka, waxaad u baahan tahay inaad hubiso inuu ku jiro diiwaanka. Xaaladeena, waxaan si fudud ugu aragnaa Docker Hub, sida ku cad Fig. 4.
Bariis 4. Sawirka loo diray diiwaanka ayaa ka soo muuqday Docker Hub.
Talaabada 4. Samee agabka Kubernetes ee codsiga
Markaa, waxaan soo aruurinay sawirka codsiga, hadda waxaan u baahanahay inaan qorno muujinta Kubernetes. Si tan loo sameeyo, Eclipse JKube waxay leedahay hawl soo saarta muuqaalo kheyraad adag oo ku saleysan qaabka Java ee hoose (, , Vert.x ama qaar kale). Waxa kale oo aad habayn kartaa muujinta adiga oo isticmaalaya faylka qaabaynta XML oo aad geliso jajabyo cayriin ah (jarjarrada caddaynta kheyraadka loo baahan yahay) galka codsiga src/main/jkube. Xaaladdan oo kale, qaabeyntaada waxaa lagu dhejin doonaa muujinta la soo saaray.
Tusaalahayaga, waxaan uga tagnay wax walba sida ay yihiin, oo sidaas darteed Eclipse JKube waxay soo saartaa caddaynta geynta caadiga ah iyo adeegga nooca ClusterIP. Kadibna kaliya ayaanu wax ka beddeleynaa adeegga muujinta si aan u beddelno nooca adeegga NodePort. Waxaad burin kartaa hab-dhaqanka aan caadiga ahayn adiga oo isticmaalaya hantida soo socota:
<jkube.enricher.jkube-service.type>NodePort</jkube.enricher.jkube-service.type>
Tani waa waxa soo-saarka shaashadda u eg yahay ka dib markii aan waydiisanno Eclipse JKube inuu qabto mvn k8s: hawsha kheyraadka.
