Qhov thib plaub version ntawm OpenShift tau tso tawm tsis ntev los no. Qhov tam sim no version 4.3 tau muaj txij li thaum kawg ntawm Lub Ib Hlis thiab tag nrho cov kev hloov pauv hauv nws yog ib yam tshiab uas tsis yog nyob rau hauv peb version, lossis qhov hloov tshiab loj ntawm qhov tshwm sim hauv version 4.1. Txhua yam uas peb yuav qhia rau koj tam sim no yuav tsum paub, nkag siab thiab coj mus rau hauv tus account los ntawm cov neeg ua haujlwm nrog OpenShift thiab npaj hloov mus rau qhov tshiab.
Nrog kev tso tawm ntawm OpenShift 4.2, Red Hat tau ua haujlwm nrog Kubernetes yooj yim dua. Cov cuab yeej tshiab thiab cov plugins tau tshwm sim rau kev tsim cov ntim khoom, CI / CD cov kav dej thiab kev xa tawm tsis muaj server. Kev tsim kho tshiab muab sijhawm rau cov neeg tsim khoom los tsom rau kev sau cov lej, thiab tsis yog cuam tshuam nrog Kubernetes.
Qhov tseeb, dab tsi tshiab hauv versions ntawm OpenShift 4.2 thiab 4.3?
Txav mus rau hybrid huab
Thaum npaj ib qho tshiab IT infrastructure lossis thaum txhim kho thaj chaw IT uas twb muaj lawm, cov tuam txhab tau xav txog huab cua mus kom ze rau kev muab cov peev txheej IT, uas lawv siv cov kev daws teeb meem huab cua ntiag tug lossis siv lub zog ntawm cov neeg muab kev pabcuam huab huab. Yog li, niaj hnub IT infrastructures tau nce zuj zus los ua raws li "hybrid" huab qauv, thaum ob qho tib si ntawm cov peev txheej thiab cov huab cua pej xeem nrog cov kev tswj hwm ib txwm siv. Red Hat OpenShift 4.2 yog tsim tshwj xeeb los ua kom yooj yim rau kev hloov pauv mus rau cov qauv huab huab thiab ua kom yooj yim rau kev sib txuas cov peev txheej los ntawm cov chaw muab kev pabcuam xws li AWS, Azure thiab Google Cloud Platform rau pawg, nrog rau kev siv huab ntiag tug ntawm VMware thiab OpenStack.
Txoj kev tshiab rau kev teeb tsa
Hauv version 4, txoj hauv kev rau kev txhim kho OpenShift tau hloov pauv. Red Hat muab cov khoom siv tshwj xeeb rau kev xa tawm OpenShift pawg - openshift-install. Cov khoom siv hluav taws xob yog ib cov ntaub ntawv binary sau hauv Go. Openshit-installer npaj cov ntaub ntawv yaml nrog rau kev teeb tsa xav tau rau kev xa tawm.
Nyob rau hauv rooj plaub ntawm kev teeb tsa siv cov kev pab huab, koj yuav tsum tau qhia me ntsis txog cov ntaub ntawv yav tom ntej: DNS cheeb tsam, tus naj npawb ntawm cov neeg ua haujlwm, cov chaw tshwj xeeb rau cov chaw muab kev pabcuam huab, cov ntaub ntawv nyiaj txiag rau kev nkag mus rau huab muab kev pabcuam. Tom qab npaj cov ntaub ntawv teeb tsa, pawg tuaj yeem siv tau nrog ib qho lus txib.
Nyob rau hauv rooj plaub ntawm kev teeb tsa ntawm koj tus kheej cov khoom siv suav nrog, piv txwv li, thaum siv huab ntiag tug (vSphere thiab OpenStack tau txais kev txhawb nqa) lossis thaum txhim kho ntawm cov hlau tsis huv, koj yuav tsum tau teeb tsa cov txheej txheem manually - npaj tsawg kawg ntawm cov tshuab virtual lossis lub cev servers yuav tsum tsim kom muaj Control Plane pawg, teeb tsa cov kev pabcuam network. Tom qab qhov kev teeb tsa no, OpenShift pawg tuaj yeem tsim tau zoo sib xws nrog ib qho kev hais kom ua ntawm openshift-installer utility.
Cov kev hloov tshiab ntawm kev tsim kho vaj tse
Kev sib koom ua ke ntawm CoreOS
Qhov hloov tshiab tseem ceeb yog kev koom ua ke nrog Red Hat CoreOS. Red Hat OpenShift master nodes tuaj yeem ua haujlwm tam sim no tsuas nyob rau hauv lub tshiab OS. Qhov no yog ib qho kev khiav hauj lwm pub dawb los ntawm Red Hat uas yog tsim los tshwj xeeb rau cov thawv daws teeb meem. Red Hat CoreOS yog lub teeb yuag Linux zoo rau kev khiav ntim.
Yog hais tias nyob rau hauv 3.11 lub operating system thiab OpenShift muaj nyias, ces nyob rau hauv 4.2 nws yog inextricably txuas nrog OpenShift. Tam sim no qhov no yog ib qho khoom siv - hloov tsis tau kev tsim kho.

Yav dhau los, txhawm rau hloov kho OpenShift, koj thawj zaug yuav tsum tau hloov kho lub hauv paus kev ua haujlwm uas cov khoom tau ua haujlwm (thaum lub sijhawm, Red Hat Enterprise Linux). Tsuas yog tom qab ntawd tuaj yeem hloov kho OpenShift maj mam, ntawm node ntawm node. Tsis muaj lus hais txog kev ua haujlwm ntawm cov txheej txheem.
Tam sim no, txij li OpenShift Container Platform tag nrho tswj cov tshuab thiab cov kev pabcuam ntawm txhua lub ntawm, suav nrog OS, txoj haujlwm no tau daws los ntawm nias lub pob los ntawm lub vev xaib interface. Tom qab no, tus neeg teb xov tooj tshwj xeeb tau pib ua haujlwm hauv OpenShift pawg, uas tswj hwm tag nrho cov txheej txheem hloov tshiab.
New CSI
Qhov thib ob, CSI tshiab yog qhov chaw cia khoom interface uas tso cai rau koj los txuas ntau yam kev cia sab nraud rau OpenShift pawg. Ntau tus neeg tsav tsheb cia rau OpenShift tau txais kev txhawb nqa raws li cov tsav tsheb cia uas tau sau los ntawm cov chaw tsim khoom cia lawv tus kheej. Ib daim ntawv teev tag nrho ntawm cov neeg tsav tsheb uas txhawb CSI tuaj yeem pom hauv daim ntawv no: . Hauv daim ntawv teev npe no koj tuaj yeem pom tag nrho cov qauv tseem ceeb ntawm disk arrays los ntawm cov tuam txhab ua lag luam (Dell/EMC, IBM, NetApp, Hitachi, HPE, PureStorage), SDS daws (Ceph) thiab huab cia (AWS, Azure, Google). OpenShift 4.2 txhawb CSI tsav tsheb ntawm CSI specification version 1.1.
RedHat OpenShift Service Mesh
Raws li Istio, Kiali thiab Jaeger tej yaam num, Red Hat OpenShift Service Mesh, ntxiv rau cov dej num ib txwm ua ntawm kev thov ntawm cov kev pabcuam, tso cai rau lawv taug qab thiab pom qhov pom. Qhov no pab cov neeg tsim khoom sib txuas lus yooj yim, saib xyuas, thiab tswj cov ntawv thov siv hauv Red Hat OpenShift.
Kev pom ntawm daim ntawv thov muaj microservice architecture siv Kiali
Txhawm rau kom yooj yim rau kev teeb tsa, kev saib xyuas, thiab kev tswj hwm lub neej ntawm Service Mesh kom ntau li ntau tau, Red Hat OpenShift muab cov thawj coj nrog tus neeg ua haujlwm tshwj xeeb, Tus Neeg Ua Haujlwm Mesh. Qhov no yog tus neeg teb xov tooj Kubernetes uas tso cai rau koj siv Istio, Kiali thiab Jaeger reconfigured tej pob khoom ntawm ib pawg, ua kom lub nra hnyav ntawm kev tswj cov ntawv thov.
CRI-O hloov Docker
Lub thawv ntim lub sijhawm ua haujlwm Docker tau hloov pauv los ntawm CRI-O. Nws muaj peev xwm siv CRI-O twb nyob rau hauv version 3.11, tab sis nyob rau hauv 4.2 nws tau los ua lub ntsiab. Tsis zoo los yog phem, tab sis ib yam dab tsi yuav tsum nco ntsoov thaum siv cov khoom.
Cov neeg ua haujlwm thiab kev siv cov ntawv thov
Cov neeg ua haujlwm yog lub chaw tshiab rau RedHat OpenShift, uas tau tshwm sim hauv plaub version. Nws yog ib txoj hauv kev ntim khoom, xa tawm, thiab tswj cov ntawv thov Kubernetes. Nws tuaj yeem xav tias yog lub plugin rau cov ntawv thov siv hauv cov thawv, uas tau tsav los ntawm Kubernetes API thiab kubectl cov cuab yeej.
