ICanonical isanda kukhipha incwadi ethi ukukhishwa kwenguqulo entsha ye-Ubuntu Core 22, inguqulo ehlangene yokusatshalaliswa kwe-Ubuntu eyenzelwe ukusetshenziswa emishinini yezimboni nabathengi ye-Inthanethi Yezinto (IoT), iziqukathi, nezinto zokusebenza.
I-Ubuntu Core isebenza njengesisekelo sokusebenzisa izingxenye ezengeziwe nezinhlelo zokusebenza, ezipakishwe njengama-plugin aziqukethwe ngokwawo ngefomethi ye-snap. Izingxenye ze-Ubuntu Core, okuhlanganisa isistimu eyisisekelo, i-Linux kernel, nama-plugin esistimu, nazo zinikezwa ngefomethi ye-snap futhi ziphathwa yikhithi yamathuluzi e-snapd. Ubuchwepheshe be-Snappy benza kube nokwenzeka ukuthwebula uhlelo lulonke, ngaphandle kokuluhlukanisa lube amaphakheji ahlukene.
Esikhundleni sokubuyekezwa okuhleliwe ezingeni lamaphakheji e-deb ngayinye, Ubuntu Core isebenzisa indlela yokuvuselela i-athomu kumaphakheji we-snap kanye nesistimu yesisekelo, efana ne-Atomic, ChromeOS, Endless, CoreOS, ne-Fedora Silverblue. Lapho uthuthukisa indawo eyisisekelo kanye namaphakheji we-snap, kungenzeka ukuthi ubuyele enguqulweni yangaphambilini, uma kwenzeka izinkinga zibonakala ngemva kokuthuthukiswa. Njengamanje kunamaphakethe we-snap angaphezu kuka-4500 kukhathalogi ye-SnapCraft.
Ukuqinisekisa ukuphepha, ingxenye yesistimu ngayinye iqinisekiswa kusetshenziswa isiginesha yedijithali, okuvumela ukuthi uvikele ukusatshalaliswa ekwenzeni izinguquko ezifihliwe noma ukufaka amaphakheji we-snap angaqinisekisiwe. Izingxenye ezilethwe ngefomethi ye-Span zihlukaniswa yi-AppArmor kanye ne-Seccomp, okudala umngcele owengeziwe wokuvikela uhlelo uma kwenzeka izicelo ezingazodwana zifakwa engcupheni.
Isistimu yesisekelo ihlanganisa kuphela isethi encane yezinhlelo zokusebenza ezidingekayo, ezinganciphisanga nje ubukhulu bendawo yesistimu, kodwa futhi zibe nomthelela omuhle ekuvikelekeni ngokunciphisa ama-vector okuhlasela okungenzeka.
Isistimu yefayela engaphansi ikhwezwe ukufunda kuphela. Kungenzeka ukusebenzisa ukubethela kwedatha kudrayivu usebenzisa i-TPM. Izibuyekezo zikhishwa njalo, zilethwa ngemodi ye-OTA (emoyeni), futhi zivumelaniswa nokwakhiwa kwe-Ubuntu 22.04.
Izindaba eziyinhloko ze-Ubuntu Core 22
Kule nguqulo entsha eyethulwa, kugqanyiswe ukuthi kuhlongozwa umqondo wamasethi ephakethe aqinisekisiwe (Amasethi okuqinisekisa), okuthi ivumela ukuchaza isethi yamaphakheji we-snaps nezinguqulo zawo kanjalo yedwa ingafakwa futhi ithuthukiswe ndawonye. Amasethi ahloliwe angasetshenziselwa ukuphoqelela imikhawulo ukuze ufake kuphela amaphakheji athile we-snap, ukusabalalisa kabusha amaphakheji akho ahloliwe futhi aqinisekisiwe, noma ukwenza lula ukuphatha ukuncika.
Olunye ushintsho olubalulekile kule nguqulo entsha ye-Ubuntu Core 22 ukuthi wengeze amathuluzi okuvuselela imvelo ye-Ubuntu Core 20 ukuze ibe yinguqulo engu-22 ngaphandle kokufakwa kabusha, kanye nekhono lokusetha kabusha izilungiselelo zibe esimweni sazo sangempela (ukusetha kabusha kwasefekthri) kwasetshenziswa.
Ngakolunye uhlangothi, singathola futhi ukuthi ukusekelwa kwamaqembu we-quota kungeziwe ukuze kukhawulwe i-CPU nezinsiza zenkumbulo ezihlotshaniswa namaqembu athile wesevisi wezifinyezo.
Kuyaziwa futhi ukuthi ukusekelwa kwekhithi yamathuluzi ye-MicroK8s, enikeza inguqulo eyenziwe lula yesikhulumi se-orchestration ye-Kubernetes, ngaphezu kokuphakamisa okuhlukile kwephakheji nge i-Linux kernel, kufaka phakathi amapeshi we-PREEMPT_RT futhi iqondiswe ekusetshenzisweni kwayo ezinhlelweni zesikhathi sangempela.
Kwezinye izinguquko ezigqamayo kule nguqulo entsha ye-Ubuntu Core 22:
- Ukwesekwa okwengeziwe kwekhithi yamathuluzi ye-MAAS (Metal-as-a-Service) ukuze kusetshenziswe ngokushesha izilungiselelo kuwo wonke amasistimu amaningi.
- Kungezwe usekelo lwe-cloud-init ukuze kulungiselelwe isistimu esigabeni sokuqalisa.
Okokugcina uma unentshisekelo yokwazi kabanzi ngakho mayelana nale nguqulo entsha, ungabheka imininingwane Kulesi sixhumanisi esilandelayo.
Landa bese uthola
I-Ubuntu Core iza ngendlela yesithombe sesistimu yesisekelo se-monolithic engahlukaniseki, esingasebenzisi ukuhlukaniswa kube amaphakheji e-deb ahlukene. Ubuntu Core 22 izithombe, ezivumelaniswe nesisekelo sephakheji ye-Ubuntu 22.04, zilungiselwe izinhlelo ze-x86_64, ARMv7 kanye ne-ARMv8. Isikhathi sokulandelela ukukhishwa yiminyaka eyi-10.
