Yechina vhezheni yeOpenShift yakaburitswa nguva pfupi yadarika. Iyo yazvino vhezheni 4.3 yave iripo kubva mukupera kwaNdira uye zvese shanduko mairi ingave chinhu chitsva chose icho chaive chisiri muyechitatu vhezheni, kana huru update yezvakaonekwa muvhezheni 4.1. Zvese zvatichakuudza izvozvi zvinoda kuzivikanwa, kunzwisiswa uye kuverengerwa nevaya vanoshanda neOpenShift uye kuronga kuchinjira kune imwe vhezheni.
Nekuburitswa kweOpenShift 4.2, Red Hat yakaita kuti kushanda neKubernetes kuve nyore. Zvishandiso zvitsva nemapulagi akaonekwa ekugadzira midziyo, CI/CD mapaipi uye serverless deployments. Zvitsva zvinopa vanogadzira mukana wekutarisa kunyora kodhi, uye kwete kubata neKubernetes.
Chaizvoizvo, chii chitsva mumavhezheni eOpenShift 4.2 uye 4.3?
Kuenda kumakore akasanganiswa
Paunenge uchironga hurongwa hutsva hweIT kana paunenge uchigadzira iripo IT landscape, makambani ari kuwedzera kufunga nezvegore nzira yekupa IT zviwanikwa, izvo zvavanoshandisa yakavanzika gore mhinduro kana kushandisa simba reruzhinji vanopa makore. Nekudaro, zvemazuva ano zvivakwa zveIT zviri kuwedzera kuvakwa zvinoenderana ne "hybrid" yegore modhi, apo zvese zviri pa-nzvimbo zviwanikwa uye veruzhinji makore zviwanikwa zvine yakajairika manejimendi system inoshandiswa. Red Hat OpenShift 4.2 yakanyatsogadzirirwa kurerutsa shanduko kune yakasanganiswa gore modhi uye inoita kuti zvive nyore kubatanidza zviwanikwa kubva kune vanopa vakaita seAWS, Azure neGoogle Cloud Platform kune sumbu, pamwe nekushandisa akavanzika makore paVMware uye OpenStack.
Nzira itsva yekuisa
Mushanduro yechina, maitiro ekuisa OpenShift achinja. Red Hat inopa yakakosha yekushandisa yekushandisa OpenShift cluster - openshift-install. Izvo zvinoshandiswa ibhinari imwe faira yakanyorwa muGo. Openshit-installer inogadzirira yaml faira ine gadziriso inodiwa pakutumirwa.
Kana yekumisikidzwa uchishandisa gore zviwanikwa, iwe unozofanirwa kutsanangura kushoma ruzivo nezve remangwana cluster: DNS zone, nhamba yevashandi node, yakatarwa marongero emupi wegore, ruzivo rweakaunti yekuwana mupi wegore. Mushure mekugadzirira iyo faira yekumisikidza, iyo cluster inogona kuendeswa nemirairo imwe.
Kana yekumisikidzwa pane yako makomputa zviwanikwa, semuenzaniso, kana uchishandisa yakavanzika gore (vSphere uye OpenStack inotsigirwa) kana kana uchiisa pane isina simbi maseva, iwe unozofanirwa kugadzirisa nemaoko zvivakwa - gadzirira huwandu hushoma hwemakina chaiwo kana. maseva emuviri anodiwa kugadzira Kudzora Ndege sumbu, gadzirisa network masevhisi. Mushure mekugadzirisa uku, sumbu reOpenShift rinogona kugadzirwa nenzira imwechete nekuraira kweiyo openshift-installer utility.
Zvigadziriso zvezvivakwa
CoreOS kubatanidzwa
Iyo yakakosha yekuvandudza ndeyekubatanidzwa neRed Hat CoreOS. Red Hat OpenShift master node zvino anogona kushanda chete pa OS itsva. Iyi yemahara sisitimu yekushandisa kubva kuRed Hat iyo yakagadzirirwa yakanangana nemidziyo mhinduro. Red Hat CoreOS iLinux yakareruka yakagadziridzwa yekumhanyisa midziyo.
Kana muna 3.11 sisitimu yekushandisa uye OpenShift yaivepo zvakasiyana, zvino mu4.2 yakabatana zvisingaite neOpenShift. Zvino ichi chishandiso chimwe chete - isingachinjiki zvivakwa.
Kune masumbu anoshandisa RHCOS kune ese node, kusimudzira OpenShift Container Platform iri nyore uye rakanyanya kuita otomatiki maitiro.
Pakutanga, kuti uvandudze OpenShift, waifanira kutanga wagadzirisa iyo yepasi sisitimu yekushandisa iyo chigadzirwa chaishanda (panguva iyoyo, Red Hat Enterprise Linux). Ipapo chete ndipo paizogona OpenShift kuvandudzwa zvishoma nezvishoma, node nenode. Pakanga pasina kutaura nezve otomatiki yacho.
Zvino, sezvo OpenShift Container Platform inodzora zvizere masisitimu nemasevhisi pane imwe neimwe node, kusanganisira iyo OS, basa iri rinogadziriswa nekudzvanya bhatani kubva pawebhu interface. Mushure meizvi, anoshanda akakosha anotangwa mukati meiyo OpenShift cluster, iyo inodzora iyo yese yekuvandudza maitiro.
CSI itsva
Kechipiri, iyo CSI nyowani ndeye yekuchengetedza interface controller iyo inokutendera kuti ubatanidze akasiyana ekunze ekuchengetedza masisitimu kune OpenShift cluster. Huwandu hukuru hwekuchengetera vatyairi vanopa OpenShift vanotsigirwa zvichibva pakuchengetedza madhiraivha ayo akanyorwa nevagadziri vekuchengetedza system ivo pachavo. Rondedzero yakazara yevanotsigirwa CSI vatyairi vanogona kuwanikwa mugwaro iri: .
