25 tau ki muri, ka uru atu a Java ki roto i te kaupapa o te kaupapa, a, ka mutu ko tetahi o nga kaupapa matua e hangaia ana nga puranga tono. I tenei ra, he maha nga taangata me nga whakahaere kua piripono ki a Java mo nga tau maha e pukumahi ana ki te heke, ki te whakaaro ranei ki te heke ki te turanga. ko ona huatanga penei ranei .
Ko te mea pouri, he kurupae ako a Kubernetes me te whakauru i tetahi atu paparanga mahi ki roto i te tukanga whanaketanga e waia ana e nga kaihōtaka Java. I tenei ra ka korero matou ki a koe me pehea te whakamahi , ki te whakangawari i enei mahi taapiri e hono ana ki nga Kubernetes me nga ipu, me te whakarite kia kore e mamae te heke ki te papaaa kapua i te wa e mau tonu ana te rauwiringa kaiao Java. Ano, ka whakaatu maatau me pehea te tuku tono Java i runga i te papaaho OpenShift ma te whakamahi i te mono OpenShift Maven.
Tukatuka Whakawhanake Java tuku iho
Te tukanga whanaketanga tuku iho (Whakaahua 1) ka uru ki te waehere tuhi kaiwhakawhanake, katahi ka hanga i nga waahanga whakaurunga ki te ahua o nga konae JAR, WAR ranei, katahi ka tohatoha me te whakahaere i enei konae ki runga i te paetukutuku, i te tūmau tono ranei. Ko te huarahi matua ki te mahi i tenei ko te whakamahi i te Maven mai i te raina whakahau, te whakamahi ranei i te IDE penei i a IntelliJ, Eclipse ranei hei tohu me te kiki i nga tono. Ka whakamahia nga kaihanga ki te whakarereke i nga waehere me te whakamatautau i nga mea katoa i mua i te tuku i te waehere me te tuku ki te mana putanga.
raihi. 1. Te tukanga whanaketanga Java tawhito.
Tukanga Whakawhanake Java mo te Kapua
Ina neke ki nga tono kapua, ko Kubernetes me . Na, inaianei me kii te kaiwhakawhanake i nga tono Java me te hanga whakaaturanga Kubernetes e whakaatu ana i enei whakaahua. Ka tukuna enei whakaaturanga ki te tūmau whakaputa e whakahaere ana i a Kubernetes. Ka huri, ka tangohia e Kubernetes enei whakaahua mai i te rehita me te tuku tono kia rite ki nga whirihoranga kua tuhia e matou ki nga whakaaturanga, he konae YAML te nuinga.
Ko te metamorphosis o te tukanga whanaketanga Java tawhito i roto i te whakawhiti ki te kapua e whakaatuhia ana i te Fig. 2.

Eclipse JKube
Ko te heke ki Kubernetes ka taapirihia he paparanga mahi ki te mahi whanaketanga, a he maha nga kaiwhakawhanake kei te mataku mo tera na te mea kei te pirangi ratou ki te aro ki a raatau mahi matua—te arorau tono—kaore i te pehea ki te tuku. A koinei te waahi ka uru mai. , ka taea e nga kaiwhakawhanake te whakamahi i o raatau whare pukapuka me o raatau taputapu ( me te ranei ) kia ngawari te mahi ipu me nga mahi e pa ana ki nga Kubernetes ma te whai i te hoahoa i te Whakaahua. 2.
I te toenga o tenei tuhinga, ka whakaatu matou ki a koe me pehea te whakangawari i te tukanga whanaketanga Java i roto i te taiao Kubernetes ma te whakamahi i te Eclipse JKube me te Kubernetes Maven Plugin.
Tukanga Whakawhanake Kapua Ma te Eclipse JKube
Kia whai whakaaro tatou ki tetahi kaupapa whanaketanga Java kua whakarerekehia mo te kapua mai i te Whakaahua 2, me te whakauru i te Eclipse JKube me te Kubernetes Maven Plugin ki roto, penei i te Whakaatu. 3.
raihi. 3. Te tukanga whanaketanga Java mo te kapua e whakamahi ana i te Eclipse JKube.
Ka kite tatou, i konei ko nga mahi katoa mo te taunekeneke me nga Kubernetes me nga ipu (kua tohua ki te whero i te hoahoa) ka whakakapihia e nga mahi taunoa Eclipse JKube, kua whakarārangihia ki te Ripanga. 1.

Inaianei me titiro ki nga tauira o te whakamahi i te Eclipse JKube me te Kubernetes Maven Plugin i te wa e mahi ana me nga tono.
Te tuku Taupānga Java ki nga Kubernetes Ma te Eclipse JKube
I tenei tauira ka tukuna e matou he tono Java ngawari ki runga i te tautau te whakamahi i Eclipse JKube. Ma te whakamahi i te Kubernetes Maven monomai, ka taea e tatou te whakarite i nga tawhā horahanga me te kore e tuhi i tetahi whirihoranga.
Hei tauira tauira ka whakamahia e matou , e whakaputa ana i te putanga JSON i te pito mutunga / tupurangi:
~/work/repos/eclipse-jkube-demo-project : $ curl localhost:8080/random | jq .

}
Hipanga 1. Tikiake Kubernetes Maven monomai
Ko Kubernetes Maven monomai kei roto i te putunga . Hei whakamahi i te Eclipse JKube me taapiri koe i te Kubernetes Maven monomai ki to pom.xml hei whakawhirinakitanga:
<plugin>
<groupId>org.eclipse.jkube</groupId>
<artifactId>kubernetes-maven-plugin</artifactId>
<version>${jkube.version}</version>
</plugin>
Mena ka whakamahia te OpenShift hei utu mo nga Kubernetes parakore, ka whakarereketia te pom.xml penei:
<plugin>
<groupId>org.eclipse.jkube</groupId>
<artifactId>openshift-maven-plugin</artifactId>
<version>${jkube.version}</version>
</plugin>
Hipanga 2. Hangaia te ahua docker
Ka taea te hanga i te konae JAR o te tono me te tono mokihi mvn, katahi ka taea te mahi mvn goal k8s:build ki te hanga whakaahua docker o te tono. Kia mahara kua whakakorehia e matou te ingoa whakaahua taunoa me tenei taonga:
<jkube.generator.name>docker.io/rohankanojia/random-generator:${project.version}</jkube.generator.name>
I mua i te hanga i te ahua, me mohio koe kei te whakaatu tika te daemon docker. Ka taea tenei ma te whakahau e whai ake nei:
$ eval $(minikube docker-env)
Na ka uru matou ki te mvn k8s: hanga whakahau, a koinei te mea ka kitea e matou i runga i te mata i te wa e hanga ana te ahua docker ma te whakamahi i te mahi hanga Eclipse JKube:

raihi. 4. Ko te ahua i tukuna ki te rehita i puta i Docker Hub.
Hipanga 4. Hangaia nga whakaaturanga rauemi Kubernetes mo te tono
Na, kua kohia e matou te ahua tono, inaianei me tuhi nga whakaaturanga Kubernetes. Hei mahi i tenei, he mahi ta Eclipse JKube e whakaputa ana i nga whakaaturanga rauemi pakari i runga i te anga Java kei raro (, , Vert.x etahi atu ranei). Ka taea hoki e koe te whakarite i te whakaaturanga ma te whakamahi i te konae whirihoranga XML me te whakatakoto i nga kongakonga mata (nga kongakonga o te whakaaturanga rauemi e hiahiatia ana) ki te kōpaki tono src/main/jkube. I tenei keehi, ka tukuna to whirihoranga ki nga whakaaturanga kua mahia.
I roto i ta maatau tauira, ka waiho e matou nga mea katoa, na reira ka hangaia e Eclipse JKube he whakaaturanga mo te tukunga taunoa me te ratonga me te momo ClusterIP. Na ka whakarerekēhia te whakaaturanga ratonga hei huri i te momo ratonga ki NodePort. Ka taea e koe te whakakore i te whanonga taunoa ma te whakamahi i nga taonga e whai ake nei:
<jkube.enricher.jkube-service.type>NodePort</jkube.enricher.jkube-service.type>
Koinei te ahua o te putanga mata i muri i to tono ki a Eclipse JKube kia mahia te mvn k8s: mahi rauemi rauemi.

He aha atu ka taea e koe me Eclipse JKube
Na, i titiro matou ki nga mahi whainga matua a Eclipse JKube me Kubernetes Maven Plugin, e whakahaere ana i te whakawhanaketanga o nga tono Java mo te papaaho Kubernetes. Mena kaore koe e hiahia ki te whakauru tonu i enei mahi mai i te papapātuhi, ka taea e koe te tuhi i roto i te whirihoranga mono, hei tauira, penei:

Te tuku tono Java i runga i te Red Hat OpenShift Ma te whakamahi i te OpenShift Maven monomai
Hei tuku i te tono mai i ta maatau tauira i runga i te papanga Red Hat OpenShift, ka whakamahia e matou te mono . Ko te rereke anake ko te hurihanga o te mahi prefix mai i te k8s ki te oc. Ma te taunoa ka mahia e te monomai Kubernetes Maven -huihuinga, me te mono OpenShift Maven - huihuinga . Kaore matou e whakarereke i to maatau kaupapa i tua atu i te tango i te taonga jkube.generator.name na te mea kaore e hiahiatia ana i te wa e pana ana ki te rehitatanga (Ka tuu e OpenShift te ahua ki roto i tana rehitatanga o roto i te waa hanga). A koinei te mea ka puta mai i runga i te mata i te wa e whakahaere ana tatou i ta tatou tauira, na te ara, ka mahia e tatou nga mahi whainga kaore i te wa kotahi, engari i te wa kotahi:
