Cov kev pabcuam tuaj yeem nthuav tawm ntau txoj hauv kev los ntawm kev qhia ib hom hauv ServiceSpec:
- ClusterIP (default) - Exposes lub Kev pabcuam ntawm tus IP sab hauv hauv pawg.
- NodePort - Exposes lub Kev pabcuam ntawm tib qhov chaw nres nkoj ntawm txhua qhov xaiv Node hauv pawg siv NAT.
Xav txog qhov no, qhov kev pabcuam nrhiav tau ua haujlwm li cas hauv Kubernetes?
Kubernetes kev pabcuam nrhiav pom yog tsim los rau cov thawv khiav hauv lub Kubernetes pawg. Yog li ntawd rau software khiav sab nraum ib Kubernetes pawg (xws li web browsers) kom nkag mus rau qhov kev pabcuam thiab web applications koj yuav tsum tau nthuav tawm cov kev pabcuam sab nrauv.
Tsis tas li ntawd, kuv yuav nkag mus rau ClusterIP li cas? Mus txog qhov ClusterIp los ntawm lub khoos phis tawj sab nraud, koj tuaj yeem qhib Kubernetes npe ntawm lub khoos phis tawj sab nraud thiab pawg. Koj tuaj yeem siv kubectl los tsim cov npe zoo li no. Thaum lub npe sawv cev, koj txuas ncaj qha rau pawg, thiab koj tuaj yeem siv tus IP sab hauv ( ClusterIp ) rau qhov Service.
Ib sab saum toj, dab tsi yog cov kev pabcuam hauv Kubernetes?
Ib qho kev pabcuam yog ib pawg ntawm cov pods uas khiav ntawm pawg. Kev pabcuam yog "pheej yig" thiab koj tuaj yeem muaj ntau yam kev pabcuam hauv pawg. Kubernetes cov kev pabcuam tuaj yeem ua haujlwm tau zoo ntawm microservice architecture. Txhua qhov kev pabcuam muaj cov lus nug pods uas txhais cov pods uas yuav ua cov ntaub ntawv rau qhov kev pabcuam.
Kubernetes ClusterIP ua haujlwm li cas?
A ClusterIP yog tus IP nkag mus tau rau sab hauv Kubernetes pawg thiab tag nrho cov kev pabcuam hauv nws. Rau NodePort, a ClusterIP yog tsim ua ntej thiab tom qab ntawd tag nrho cov tsheb thauj khoom sib npaug ntawm qhov chaw nres nkoj. Qhov kev thov raug xa mus rau ib qho ntawm Pods ntawm TCP chaw nres nkoj teev los ntawm lub hom phiajPort teb.

Peb txhua tus raug tshaj 2000 kev tshaj tawm hnub no, suav nrog tej zaum qhov kev kawm muaj zog tshaj plaws hauv zej zog
Nws yuav siv sij hawm ntev npaum li cas rau qhov kev ntiab tawm kom pom ntawm koj qhov kev txheeb xyuas keeb kwm yav dhau?
Cov qiv nyiaj yuav pom nws thaum ntsuas koj cov keeb kwm qiv nyiaj rau kev qiv tsev lossis lwm yam qiv. Kev ntiab tawm feem ntau sau npe ntawm cov ntawv ceeb toom tsis pub dhau 30 hnub ntawm lub tsev hais plaub txiav txim siab tawm tsam koj kom tawm hauv lub tsev, tab sis nws yuav siv sijhawm txog 60 hnub
Tus thawj xibfwb uas tsis tau qhia tawm yog dab tsi thaum tus thawj xibfwb yuav tsum tau nthuav tawm?
Nyob rau hauv rooj plaub ntawm tus thawj tswj hwm tsis tau qhia tawm, lawv lub neej thiab tus kheej tsis tau qhia rau tus neeg thib peb los ntawm cov lus lossis kev ua haujlwm ntawm ib qho kev tso cai. Tus thawj xibfwb uas tsis tau qhia tawm yog qhov xwm txheej thaum tus neeg thib peb tsis muaj ntawv ceeb toom tus neeg sawv cev ua haujlwm rau tus thawj xibfwb
