Chikwata chekusimudzira cheKubernetes achangobva kuburitsa kuburikidza nechiziviso kuburitswa kwe iyo nyowani vhezheni "Kubernetes 1.18" mune iro timu yekusimudzira inotaura kuti iri 'fit uye rakapedzwa' vhezheni.
Mune iyi vhezheni itsva rakakosha basa rakaitwa kugadzirisa beta uye kugadzikana mashandiro kuvimbisa a zvirinani mushandisi ruzivo. Kuyedza kwakaenzana kwakaitwa kuwedzera zviitiko zvitsva uye zvinonakidza maficha anovimbisa kuwedzera kusimudzira ruzivo rwevashandisi.
Kune avo vasingazive Kubernetes, vanofanira kuziva izvozvo yakavhurika sosi sisitimu yekushandisa kuitwa, kuyerwa uye manejimendi containerized zvinoshandiswa.
Waive yakatanga kugadzirwa neGoogle, kunyangwe hazvo kukura kwayo kwakapihwa kuOpen Source Cloud Cloud Computing Foundation (CNCF), iyo nhasi yakabvumidza tekinoroji yeorchestration tekinoroji kuti ikure nekukurumidza, nekuda kwemipiro yezvigadzirwa zvehunyanzvi.
Chii chitsva muKubernetes 1.18?
Iyi vhezheni itsva inomira kuve neye kugona kushandisa tokeni account account senzira yakajairika yekusimbisa. Semuenzaniso, kana iwe uchida pod kugadzirisa mamwe maKubernetes zviwanikwa, senge kutumirwa kana sevhisi, inogona kuverengerwa neaccount account uye kugadzira iwo anodikanwa mabasa uye anosunga basa.
Kubernetes account account (KSAs) inotumira JSON web tokens (JWT) kuseva yeAPI kuratidza. Izvi zvinoita kuti server ye API ive yega sosi yechokwadi yeakaundi account.
Kubernetes 1.18pinopa mashandiro , que inobvumira sevha yeAPI kuti ipe gwaro rekutsvaga reOverID Connect Iyo ine kiyi dzeveruzhinji dzechiratidzo mukuwedzera kune imwe metadata.
Imwe shanduko inomira kubva Kubernetes 1.81 ndiyo kugona kumisikidza HPA Velocity yemamwe pods. Horizontal Pod Autoscaler (HPA) yakashandiswaa kubvumira iyo Kubernetes cluster kuti iite otomatiki kune yakakwira / yakaderera traffic. NeHPA, mushandisi anogona kubvunza mutungamiriri kuti agadzire mamwe ma module mukupindura ma CPU spikes, zvimwe zviyero, kana zviyero zvinopihwa nechishandiso.
Kubernetes 1.18 ine muongororwo wema profiles ekumhanyisa akawanda masisitimu yemurongi. Kazhinji, kune maviri marudzi emabasa ekuremara muKubernetes: marefu-esevhisi masevhisi (semuenzaniso, webhu server, APIs, nezvimwewo) uye mabasa anomhanyisa kunopedzisa (zviri nani kuzivikanwa sezita Mabasa).
Nekuda kwemisiyano iri pachena pakati pemhando dzebasa, vamwe vashandisi vanoshandira mukugadzira masumbu akazara ezvido zvakasiyana. Semuenzaniso, rimwe sumbu rekutarisira kucherwa kwedatha uye imwe yekushandisa iyo APIs yekushandisa.
Icho chikonzero ndechekuti ivo vanoda danho rekuti sarudzo isiyane. Semuenzaniso, iyo default scheduler marongero inokurudzira yakakwira kuwanikwa.
Kune rimwe divi, isu tinogona zvakare kuwana iyo kugona kutsanangura pod kutepfenyura mutemo padanho remasumbu, chii zvaita kuti zvikwanise kuve nechokwadi chekuti pods dzicharongwa muZviwanikwa Nzvimbo (chero iwe uri kushandisa yakawanda-nzvimbo sumbu) kuverengera zvakanyanya kuwanikwa uye zviwanikwa mashandisirwo.
Iko mashandiro anogonesa iyo topologySpreadConstraints kududzirwa, iyo inoratidza nzvimbo nekutsvaga maodhi ane imwecheteyo topologyKey tag. Nzvimbo dzine imwecheteyo TopologyKey tag ndeye yenzvimbo imwechete. Iko kumisikidzwa kwaive kugovera iwo pods zvakaenzana munzvimbo dzakasiyana. Zvisinei, chinokanganisa ndechekuti iyi seti inofanira kuiswa padanho repodhi. Pods idzo dzisina kumisikidzwa hadzizogovaniswa zvakaenzana munzvimbo dzinokanganisa.
Kugumisira asi kusiri kupedzisira, isu tinogona zvakare kuwana kugona kwekuregeredza shanduko muvhoriyamu chivakwa. Nekukanganisa, kana vhoriyamu ikaiswa mumudziyo pane iyo Kubernetes cluster, mafaera ese uye madhairekitori mukati meiyi vhoriyamu vane yavo midziyo yashandurwa kuita kukosha kwakapihwa kuburikidza neiyo fsGroup.
Zvese izvi kubvumira fsGroup kuverenga nekunyora vhoriyamu. Zvisinei, maitiro aya akaratidzirwa kuve asingadiwe mune dzimwe nguva.
Iyi vhezheni itsva ye Kubernetes inouya neshanduko dzinoverengeka, uye isu tangotaura mashoma ezvakanyanya kukosha. Kana iwe uchida kuziva iyo yakazara runyorwa iwe unogona kuzviita nekushanyira iyo inotevera chinongedzo.
