ICanonical isanda kwethula ukukhishwa kwe-Ubuntu Core 20, ukusatshalaliswa okuhlangene kwe-Ubuntu okwenzelwe ukusetshenziswa kumadivayisi we-Inthanethi Yezinto (IoT), iziqukathi, imishini yezimboni neyabathengi.
Kulabo abangajwayelene ne-Ubuntu Core, kufanele ukwazi lokho lokhu kusatshalaliswa kusebenza njengesisekelo sokuqalisa izinto ezingeziwe nezinhlelo zokusebenza, aklanyelwe njengama-plug-standalone ngefomethi ye-snap.
Izingxenye ze-Ubuntu Core, kufaka phakathi i-base system, i-Linux kernel, nama-plugins wesistimu, futhi kuhlinzekwe ngefomethi ye-snap futhi ziphethwe yithuluzi lamathuluzi le-snapd, lapho ubuchwepheshe be-Snappy buvumela khona ukwakha isithombe sohlelo lonke, ngaphandle kokuhlukaniswa ngamaphakeji ahlukile.
Mayelana Ubuntu Core
Ku-Ubuntu Core esikhundleni sezibuyekezo ezengeziwe ezingeni lamaphakheji wesikweletu ngamanye, Ubuntu Core isebenzisa indlela yokuvuselela i-athomu amaphakheji we-snap kanye nohlelo lwesisekelo, ifana ne-Atomic, i-Chrome OS, Okungapheli, iCoreOS, neFedora Silverblue.
Lapho uvuselela imvelo eyisisekelo futhi uqhafaza, kungenzeka ukuthi ubuyele enguqulweni yangaphambilini uma kunezinkinga ezikhonjwe ngemuva kokuvuselelwa. Okwamanje kunamaphakeji we-snap angaphezu kuka-6000 kukhathalogi ye-SnapCraft.
Ukuqinisekisa ukuphepha, ingxenye ngayinye yohlelo iqinisekiswa ngesiginesha yedijithali, ekuvumela ukuthi uvikele ukusatshalaliswa ekwenzeni ukulungiswa okufihliwe noma ukufaka amaphakheji we-snap angaqinisekisiwe.
Izinto ezilethwe ngefomethi ye-snap ehlukanisiwe kusetshenziswa i-AppArmor ne-Seccomp, ukudala umugqa owengeziwe wokuvikela uhlelo uma ngabe izinhlelo ngazinye zengozini.
Isistimu eyisisekelo ifaka kuphela isethi ephansi yezicelo ezidingekayo, ezingagcini nje ngokunciphisa usayizi wemvelo yohlelo, kepha futhi zibe nomthelela omuhle kwezokuphepha ngokunciphisa ama-vectors ahlaselayo.
Isistimu yefayela eyisisekelo ifakwa kuphela ukufundwa. Ukuvuselelwa kukhishwa njalo, kulethwe kumodi ye-OTA (over-the-air), futhi kuvumelaniswe ne-Ubuntu 20.04.
Ukunciphisa ithrafikhi, izibuyekezo zilethwa ngendlela ecindezelwe futhi zifaka kuphela izinguquko ezihlobene nokuvuselelwa kwangaphambilini (izibuyekezo ze-delta). Ukufaka izibuyekezo ezizenzakalelayo kuxazulula izingqinamba zokulondeka kohlelo lapho kusetshenziswa kumadivayisi ashumekiwe.
Ngokuhlukanisa ngokunengqondo uhlelo oluyisisekelo kuzinhlelo zokusebenza, abathuthukisi be-Ubuntu bagcina i-Ubuntu Core base base-to-date futhi abathuthukisi babo banakekela ukubaluleka kwezinhlelo ezengeziwe.
Le ndlela ivumela ukunciphisa izindleko zokugcinwa kwemikhiqizo, imvelo yayo yesoftware eyakhelwe ngesisekelo se-Ubuntu Core, ngoba abenzi bayo abadingi ukubhekana nokukhishwa kanye nokulethwa kwezibuyekezo zohlelo futhi bagxile kuphela kuzinto zabo ezithile.
Izindaba eziyinhloko ze-Ubuntu Core 20
Kule nguqulo entsha ekhishiwe, enye yezinto ezintsha ezisemqoka Okugqamayo yilokho ukusekelwa okusemthethweni sekuqalisiwe yamapuleti ahlukahlukene I-Raspberry Pi isuselwa kuma-chip angama-32-bit no-64-bit ARM.
Futhi, ingeze amandla okusebenzisa ukubethela okugcwele kwediski ngokuhlanganiswa kwe-TPM (Module Platform Module). Ukubethela okwamanje kutholakala kuphela ezinhlelweni ze-x86 (ze-ARM kuzovela ngokuhamba kwesikhathi).
Futhi kuvela nokuthi izindlela zokuthola nokufaka kabusha zingeziwe ohlelweni (ukuqaliswa kwedivayisi kusetshenziswa uhlobo olukhethiwe).
Kwezinye izinguquko okuvelele kunguqulo entsha:
- Imenyu yebhuthi inikezwa ukukhetha inketho yebhuthi bese iya kumodi yokutakula. Imenyu iboniswa ngokubamba inkinobho ethi «1» kusigaba sokuqala sokulayisha.
- Kungezwe ukusekelwa kokuqala kwe-Metal-as-a-Service (MAAS) Toolkit ukwenza ngokushesha ukucushwa kuzinhlelo eziningi.
- Kungezwe ukusekelwa kokuqala kwe-cloud-init yokumiswa kwesistimu esigabeni sokuqalisa.
Okokugcina uma unesifiso sokwazi okwengeziwe ngakho yenguqulo entsha ye-Ubuntu Core 20, ungabheka ifayela le- isixhumanisi esilandelayo.
Landa bese uthola Ubuntu Core 20
Izithombe ze-Ubuntu Core 20, ezivumelaniswa ne-Ubuntu 20.04 base base, zilungiselelwe ama-x86_64, ARMv7, kanye nezinhlelo ze-ARMv8.
Ukuthola isithombe sesistimu, unga kusuka kusixhumanisi esingezansi.
