Vhiki rapfuura kuvhurwa kweshanduro nyowani ye iyo chikuva orchestration chikuva Kubernetes 1.18, vhezheni iyo inosanganisira 38 shanduko uye kugadzirisa, ayo gumi nemashanu ari akatsiga mamiriro uye gumi nemaviri ari beta nyika, kuwedzera kune 12 nyowani alpha yenyika shanduko dzinokurudzirwa. Mukugadzirira iyo vhezheni nyowani, kuyedza kwakaenzana kwakanangiswa zvese kunatsiridzwa kwemabasa akasiyana siyana uye kugadzikana kwesimba rekuyedza, pamwe nekubatanidzwa kwezvinoitika zvitsva.
Kune avo vasina kujairira Kubernetes, iwe unofanirwa kuziva izvo ichi chigadziko orchestration rig , que inobvumidza iwe kubata sumbu remidziyo yakasarudzika seyakazara uye zvinopa nzira dzekuisa, kuchengetedza uye kuyera zvishandiso zvinomhanya mumidziyo.
Iyo purojekiti yakatanga kugadzirwa neGoogle asi yakazoendeswa kune yakasarudzika chikuva, Yakarongedzwa neLinux Foundation. Ipuratifomu yakaiswa semhinduro yepasirese yakagadzirirwa nharaunda, isina kubatana nehurongwa hwemunhu uye inokwanisa kushanda nechero application mune chero gore renharaunda. Iyo Kubernetes kodhi yakanyorwa muGo uye inoparadzirwa pasi peApache 2.0 rezinesi.
Chii chitsva muKubernetes 1.18?
Iyi vhezheni itsva ye Kubernetes inouya nezvakasiyana zvinowedzera zveKubectl, yazvinotaurwa mune kushambadza iyo akawedzera iyo alpha vhezheni ye "kubectl debug" rairo, izvo zvinoita kuti zvive nyore kugadzirisa mune pods kana uchimhanyisa midziyo ine ekugadzirisa maturu.
Nepo iwo murairo "Kubectl diff" yakaziviswa kugadzikana, iyo inobvumidza iwe kuti uone izvo zvichachinja musumbu kana iwe ukaisa iyo expression.
Uyewo ese "kubectl run" jenareta emagetsi abviswa, kunze kwekutanga chete pod jenareta kutanga, pamwe nechiratidzo -Kumhanya-mhanya kwakachinjwa, zvinoenderana nekukosha kwayo (mutengi, sevha, uye hapana), iko kuyedzwa kuitiswa kwemirairo kunoitwa kune mutengi kana server server.
Iyo kodhi kubectl inopihwa kune yakasarudzika nzvimbo. Izvi zvakatibvumidza isu kupatsanura kubectl kubva mukati memabernetes kutsamira uye zvakaita kuti zvive nyore kupinza kodhi muzvikamu zvechitatu-bato.
Kana zvakadaro shanduko yenetiweki, zvinoonekwa kuti IPv6 rutsigiro rwuri mubeta, yakawedzera PVC kuumbana, mukana wekuvharira michina mbishi senge diski dzisingaperi, rutsigiro rwekuvharira michina mbishi muCSI, kuendesa ruzivo pamusoro pekutyaira kukumbira kubatanidza diski kumutungamiriri weCSI, pamwe kuti iyo nyowani "isingachinjiki" munda wawedzerwa kune iyo ConfigMap uye Chakavanzika zvinhu.
Pane dzimwe shanduko dzinobuda pachena:
- Iko kugona kushandisa kwakadzoserwa API boka / v1beta1 maapplication uye / v1beta1 yekuwedzera kwakazobviswa.
- ServerSide Nyorera yakagadziridzwa kune beta2 nyika. Uku kusimudzira kunounza kubectl chinhu chinonyengera kune iyo API server.
- CertificateSigningRequest API yakaziviswa kugadzikana.
- Tsigiro yeiyo Windows chikuva.
- Windows node rutsigiro inoenderera ichiwedzera
- CRI-ContainerD kutsigira
- RuntimeClass kuitiswa
- CSI Marshal
- Kutamisirwa rutsigiro kwave kugadzikana
- Akaundi yakachengetedzwa account account
- RunAsUserName
- Mutungamiriri weTopology akagamuchira chinzvimbo chebeta. Icho chimiro chinosanganisira kugoverwa kweNUMA, iyo inodzivirira kudzikisira kwekuita pane akawanda masokisi masisitimu.
- Chimiro cheBeta chakawanikwa uchishandisa iyo PodOverhead basa, iro rinokutendera kuti utaure muRuntimeClass iyo yakawedzera huwandu hwezvinhu zvinodiwa kutanga imba.
- Yakawedzerwa hugepages rutsigiro, alpha yekuzvimiririra chinzvimbo chakawedzerwa mumudziyo uye rutsigiro rwemazhinji-chikamu chikamu makuru makuru
- Yakawedzera AppProtocol munda umo iwe unogona kudoma kuti ndeipi protocol inoshandiswa neapp
- Inoshandurwa kune beta mamiriro uye inogoneswa neyakagadzika EndpointSlicesAPI, inova iyo inoshanda inoshanda kutsiva kweyakajairwa Endpoints.
- Chinhu cheIngressClass chakawedzerwa, zvichiratidza zita remutyairi wekuisa, mamwe maparameter, uye chiratidzo chekuchishandisa nekukanganisa.
- Wakawedzera kugona kudoma muHPA kuratidza mwero wehasha kana uchichinja huwandu hwedzimba dziri kushanda, ndiko kuti, kana mutoro uchiwedzera, zvinobva zvangotanga N times mamwe makopi.
