Canonical ichangobva kuburitsa iyo kuburitswa kweiyo vhezheni itsva yeUbuntu Core 22, compact vhezheni yekugovera Ubuntu yakagadzirirwa kushandiswa pamaindasitiri uye mutengi Internet yezvinhu (IoT) zvishandiso, midziyo, uye michina.
Ubuntu Core inoshanda sehwaro hwekumhanyisa zvimwe zvikamu uye maapplication, iyo yakarongedzwa se-ega-ine plugins mune snap fomati. Ubuntu Core components, zvinosanganisira base system, Linux kernel, uye system plugins, inopihwawo mune snap fomati uye inotungamirwa neiyo snapd toolkit. Snappy tekinoroji inoita kuti ikwanise kufananidza sisitimu yacho yese, pasina kuipatsanura mumapakeji akasiyana.
Panzvimbo pekuvandudzwa kwakarongwa pamwero wemadhibhi ega ega mapakeji, Ubuntu Core inoshandisa atomic update mechanism ye snap package uye iyo base system, yakafanana neAtomic, ChromeOS, Endless, CoreOS, uye Fedora Silverblue. Paunenge uchivandudza nzvimbo yepasi uye snap mapakeji, zvinokwanisika kudzokera kune yakapfuura vhezheni, kana matambudziko akaonekwa mushure mekusimudzira. Parizvino kune anopfuura mazana mana nemazana mashanu ezvimedu emapaketi muiyo SnapCraft katalogi.
Kuti uve nechokwadi chekuchengetedza, chikamu chega chega chehurongwa chinosimbiswa uchishandisa siginecha yedhijitari, iyo inokutendera iwe kuchengetedza kugovera kubva pakuita zvakavanzika zvigadziriso kana kuisa unverified snap package. Zvikamu zvinounzwa muSpan fomati zvakaparadzaniswa neAppArmor neSeccomp, zvichigadzira imwezve muganhu wekuchengetedzwa kwehurongwa kana maapplication emunhu akakanganiswa.
Iyo base system inosanganisira chete shoma shoma yezvikumbiro zvinodikanwa, izvo zvisina kungoderedza saizi yemamiriro ehurongwa, asi zvakare yakave nemhedzisiro yakanaka pakuchengetedza nekudzikisa zvinogona kurwisa mavector.
Iyo yepasi faira system yakaiswa kuverenga-chete. Zvinogoneka kushandisa data encryption pane drive uchishandisa TPM. Zvigadziriso zvinoburitswa nguva nenguva, zvinounzwa muOTA (pamusoro-pamhepo) modhi, uye inowiriraniswa neiyo Ubuntu 22.04 kuvaka.
Main nhau dzeUbuntu Core 22
Mune iyi vhezheni itsva inounzwa, inosimbiswa kuti iyo pfungwa yeakasimbiswa packet seti inokurudzirwa (Validation sets), izvo inobvumira kutsanangura seti ye snaps mapakeji uye neshanduro dzawo zvakadaro chete inogona kuiswa uye kukwidziridzwa pamwe chete. Maseti akaedzwa anogona kushandiswa kumanikidza zvirambidzo kungoisa chaiwo snap mapakeji, kugoverazve ako epakeji akaedzwa uye akasimbiswa, kana kurerutsa manejimendi ekuvimba.
Imwe shanduko yakakosha mune iyi vhezheni itsva yeUbuntu Core 22 ndeyekuti yakawedzera maturusi ekuvandudza Ubuntu Core 20 nharaunda kuti ishandure 22 pasina kudzoreredzwa, pamwe nekukwanisa kuseta zvakare marongero kumamiriro avo ekutanga (factory reset) yakaitwa.
Nekune rimwe divi, isu tinogona zvakare kuwana kuti rutsigiro rwemapoka ezvibodzwa rwakawedzerwa kudzikamisa iyo CPU uye zviwanikwa zvekurangarira zvine chekuita neakamwe snapshot sevhisi mapoka.
Izvo zvinoonekwawo kuti iyo rutsigiro rweMicroK8s toolkit, iyo inopa yakareruka vhezheni yeKubernetes mudziyo orchestration papuratifomu, mukuwedzera kukupawo mutsauko wepakeji ne iyo Linux kernel, kusanganisira PREEMPT_RT zvigamba uye yakanangana nekushandiswa kwayo mune chaiyo-nguva masisitimu.
Yeimwe shanduko izvo zvinomira kunze kweiyi vhezheni itsva yeUbuntu Core 22:
- Yakawedzera tsigiro yeMAAS (Metal-as-a-Service) turusi yekukurumidza kutumira zvigadziriso mumasystem akawanda.
- Yakawedzera rutsigiro rwegore-init kugadzirisa sisitimu padanho rekutanga.
Finalmente kana iwe uchifarira kuziva zvakawanda nezvazvo nezve iyi vhezheni nyowani, iwe unogona kutarisa iyo ruzivo Mune inotevera chinongedzo.
Dhawunirodha uye tora
Ubuntu Core inouya muchimiro cheisingaonekwi monolithic base system mufananidzo, usingashandisi kupatsanura kuita akasiyana dhibhi mapakeji. Ubuntu Core 22 mifananidzo, ayo anowiriraniswa neiyo Ubuntu 22.04 package base, akagadzirirwa x86_64, ARMv7 uye ARMv8 masisitimu. Iyo yekuburitswa yekutevera nguva ndeye 10 makore.
