Iviki eledlule ukwethulwa kwenguqulo entsha ye ipulatifomu ye-orchestration yesitsha IKubernetes 1.18, inguqulo leyo kufaka phakathi izinguquko ezingama-38 nokuthuthuka, kubo abangu-15 basesimweni esizinzile kanti abangu-11 basesimweni se-beta, ngaphezu kwe Kuphakanyiswa izinguquko ezintsha ze-alpha state eziyi-12. Ekulungiseleleni le nguqulo entsha, imizamo yokulingana ibhekiswe ekucwengweni kwemisebenzi ehlukahlukene nasekuqiniseni amakhono wokuhlola, kanye nasekuhlanganisweni kwentuthuko entsha.
Kulabo abangajwayelene neKubernetes, kufanele ukwazi lokho le yi-rig ye-orchestration rig lokho ikuvumela ukuphatha iqoqo leziqukathi ezikude ngokuphelele futhi unikeze izindlela zokuphaka, ukugcina kanye nokukala izinhlelo zokusebenza ezisebenza eziqukathi.
Le phrojekthi yadalwa i-Google ekuqaleni, kepha kamuva yadluliselwa kupulatifomu ehlukile, ikhethwe yiLinux Foundation. Ipulatifomu ibekwe njengesixazululo sendawo yonke esakhiwe ngumphakathi, esingaxhunyanisiwe nezinhlelo ngazinye futhi sikwazi ukusebenza nganoma yisiphi isicelo kunoma iyiphi imvelo yefu. Ikhodi yeKubernetes ibhalwe kuGo futhi isatshalaliswa ngaphansi kwelayisense le-Apache 2.0.
Yini okusha kubernetes 1.18?
Le nguqulo entsha ye IKubernetes iza nezithuthukisi ezahlukahlukene zeKubectl, okukhulunywa ngayo esikhangisweni ukuthi ungeze inguqulo ye-alpha yomyalo we- "kubectl debug", okwenza kube lula ukulungisa iphutha kumaphodi lapho usebenzisa iziqukathi ezinamathuluzi wokulungisa amaphutha.
Ngenkathi umyalo "Kubectl diff" kumenyezelwe njengokuzinza, ekuvumela ukuthi ubone okuzoshintsha kuqoqo uma usebenzisa i-expression.
Futhi wonke ama-generator "kubectl run" asusiwe, ngaphandle kwesiqalo esisodwa se-pod generator, kanye nenkomba -Dry-run Ishintshiwe, ngokuya ngenani lalo (iklayenti, iseva futhi alikho), ukwenziwa kokuhlolwa komyalo kwenziwa ohlangothini lweklayenti noma leseva.
Ikhodi i-kubectl inikezwe endaweni ehlukile yokugcina izinto. Lokhu kusivumele ukuthi sehlukanise i-kubectl kokuncika kwangaphakathi kwe-kubernetes futhi kwenze kwaba lula ukungenisa ikhodi kumaphrojekthi wezinkampani zangaphandle.
Kepha izinguquko zenethiwekhi, kuyaziwa ukuthi ukwesekwa kwe-IPv6 manje sekuku-beta, ingezwe i-PVC cloning, kungenzeka ukuthi inethiwekhi ivimbe amadivayisi aluhlaza njengamadiski waphakade, ukusekelwa kokuvimba amadivayisi aluhlaza ku-CSI, ukudluliswa kolwazi mayelana nedrayivu ecela ukuxhuma idiski kusilawuli se-CSI, ukuthi inkambu entsha "engaphenduki" ingezwe ku-ConfigMap nasezintweni eziyimfihlo.
Kwezinye izinguquko ezigqamile:
- Amandla wokusebenzisa izinhlelo ze-API ezehlisiwe / v1beta1 kanye / nezandiso ze-v1beta1 ekugcineni kususiwe.
- I-ServerSide Sebenzisa ibuyekezelwe isimo se-beta2. Lokhu kuthuthukiswa kuletha ukukhwabanisa kwento ye-kubectl kuseva ye-API.
- IsitifiketiSigningRequest API simenyezelwe sizinzile.
- Ukusekelwa kwesikhulumi seWindows.
- Ukuxhaswa kweWindows node kuyaqhubeka nokwanda
- Ukusekelwa kwe-CRI-ContainerD
- Ukuqaliswa kwe-RuntimeClass
- Ummeleli we-CSI
- Ukusekelwa okudlulisiwe kuzinzile
- I-akhawunti yesevisi ephethwe yiqembu
- I-RunAsUserName
- Umphathi weTopology uthole isimo se-beta. Isici sifaka ukusatshalaliswa kwe-NUMA, okuvimbela ukwehliswa kokusebenza kuma-socket system amaningi.
- Isimo se-beta sitholwe kusetshenziswa umsebenzi wePodOverhead, okuvumela ukuthi ucacise ku-RuntimeClass inani elengeziwe lezinsizakusebenza ezidingekayo ukuqala ikhaya.
- Ukuxhaswa kwamakhasi amakhulu kunwetshiwe, isimo sokuhlukaniswa kwe-alpha sengeziwe esitsheni nasekusekelweni kwamasayizi amakhulu wamazinga amakhulu.
- Kungezwe inkambu ye-AppProtocol lapho ungacacisa ukuthi iyiphi uhlelo lokusebenza olusetshenziswayo
- Kuhunyushelwe kusimo se-beta futhi kunikwe amandla yi-EndpointSlicesAPI ezenzakalelayo, engena esikhundleni esisebenza ngokwengeziwe sama-Endpoints ajwayelekile.
- Kungezwe into ye-IngressClass, ekhombisa igama lesilawuli sokufaka, imingcele yaso eyengeziwe, nesibonakaliso sokuyisebenzisa ngokuzenzakalela.
- Kungezwe amandla okucacisa ku-HPA kuveza izinga lobudlova lapho kuguqulwa inani lamakhaya asebenzayo, okungukuthi, lapho umthwalo unyuka, uqala ngokushesha amakhophi angama-N amaningi.
