Ithimba lokuthuthukiswa kweKubernetes usanda kukhipha ngesimemezelo ukukhishwa kwe- inguqulo entsha "Kubernetes 1.18" lapho iqembu lezentuthuko lisho khona ukuthi yinguqulo 'efanelekile futhi eqediwe'.
Kule nguqulo entsha kwenziwe umsebenzi obalulekile ukwenza ngcono ukusebenza kwe-beta nokusebenza okuzinzile ukuqinisekisa i isipiliyoni esingcono somsebenzisi. Kwenziwe umzamo ofanayo ukwengeza intuthuko entsha nezici ezintsha ezithokozisayo ezethembisa ukuqhubekisela phambili ulwazi lomsebenzisi.
Kulabo abangazi Kubernetes, kufanele bakwazi lokho uhlelo lomthombo ovulekile ukwenza i-automate ukuthunyelwa, ukukala nokuphathwa kwe- izinhlelo zokusebenza eziqukathiwe.
Fue yakhelwe ekuqaleni i-Google, yize ukuthuthuka kwayo kuphathiswe i-Open Source Cloud Computing Foundation (CNCF), namuhla evumele ubuchwepheshe be-orchestration technology ukuthi bukhule ngokushesha, ngenxa yeminikelo yezikhondlakhondla zobuchwepheshe.
Yini okusha kubernetes 1.18?
Le nguqulo entsha ivelele ngokuba ne- ikhono lokusebenzisa amathokheni we-akhawunti yesevisi njengendlela ejwayelekile yokufakazela ubuqiniso. Isibonelo, uma ufuna i-pod ukuphatha ezinye izinsizakusebenza ze-Kubernetes, njengokuthunyelwa noma insizakalo, ingahlotshaniswa ne-akhawunti yesevisi futhi yakhe izindima ezidingekayo kanye nokubophezeleka kwendima.
Ama-akhawunti wensizakalo ye-Kubernetes (KSAs) athumela amathokheni wewebhu we-JSON (JWT) kuseva ye-API ukuze aqinisekise. Lokhu kwenza iseva ye-API ukuphela komthombo wokufakazela ubuqiniso yama-akhawunti esevisi.
IKubernetes 1.18 pinikeza ukusebenza lokho ivumela isiphakeli se-API ukuthi sinikeze idokhumenti yokutholwa kwe-OpenID Connect Okuqukethe okhiye bomphakathi bethokheni ngokungeziwe kwenye imethadatha.
Olunye ushintsho olugqame kuKubernetes 1.81 yi- ikhono lokumisa i-HPA Velocity yama-pods athile. I-Horizontal Pod Autoscaler (HPA) isetshenzisiwea ukuvumela iqoqo le-Kubernetes ukuthi liphendule ngokuzenzakalela kuthrafikhi ephezulu / ephansi. Nge-HPA, umsebenzisi angacela isilawuli ukuthi sakhe amamojula amaningi ngokuphendula ama-CPU spikes, ezinye izilinganiso, noma izilinganiso ezinikezwe uhlelo lokusebenza.
I-Kubernetes 1.18 inokubuka konke kwamaphrofayli ukusebenzisa ukucushwa okuningi yomhleli. Ngokuvamile, kunezinhlobo ezimbili zemithwalo yemisebenzi eKubernetes: izinsizakalo zesikhathi eside (ngokwesibonelo, amaseva wewebhu, ama-API, njll.) Nemisebenzi eqala ukuqedwa (eyaziwa kangcono njengegama elithi Imisebenzi).
Ngenxa yomehluko osobala phakathi kwezinhlobo zomthwalo womsebenzi, abanye abasebenzisi baphendukela ekwakheni amaqoqo agcwele wezidingo ezahlukahlukene. Isibonelo, iqoqo elilodwa lokuphatha ukumba idatha kanye nokunye ukusebenzisa ama-API wohlelo lokusebenza.
Isizathu ukuthi badinga inqubo yesinqumo ukuze yehluke. Isibonelo, izilungiselelo zesihleli esizenzakalelayo zithuthukisa ukutholakala okuphezulu.
Ngakolunye uhlangothi, singathola futhi i- ikhono lokuchaza umthetho wokusakaza we-pod ezingeni leqoqo, yini kwenze kwaba nokwenzeka ukuqinisekisa ukuthi ama-pods azohlelwa ezindaweni zokutholakala (inqobo nje uma usebenzisa iqoqo lezindawo eziningi) ukuqinisekisa ukutholakala okuphezulu nokusetshenziswa kwemithombo.
Ukusebenza kuvumela ukucaciswa kwe-topologySpreadConstraints, okukhomba izindawo ngokusesha izindawo ezinomaki ofanayo we-topologyKey. AmaNode anomaki ofanayo weTopologyKey asendaweni efanayo. Ukucushwa bekungukusabalalisa ama-pod ngokulinganayo ezindaweni ezahlukahlukene. Noma kunjalo, okubi ukuthi lokhu kulungiselelwa kufanele kusetshenziswe ezingeni le-pod. Ama-pod angenakho ukumiswa ngeke asatshalaliswe ngokulinganayo ezizindeni ezinamaphutha.
Okokugcina, singathola futhi nekhono lokuziba ushintsho kumpahla yevolumu. Ngokuzenzakalelayo, lapho ivolumu ifakwa esitsheni kwiqoqo le-Kubernetes, wonke amafayela nezinkomba ezikule volomu impahla yawo ishintshelwe kunani elinikezwe nge-fsGroup.
Konke lokhu ukuvumela i-fsGroup ukuthi ifunde futhi ibhale ivolumu. Kodwa-ke, lokhu kuziphatha kukhonjisiwe njengokungathandeki kwezinye izimo.
Le nguqulo entsha ye I-Kubernetes iza nezinguquko eziningi futhi sishilo kuphela ezimbalwa ezibaluleke kakhulu. Uma ufuna ukwazi uhlu oluphelele ungakwenza ngokuvakashela ifayela le- isixhumanisi esilandelayo.
