Ukutyhilwa kweCanonical kutshanje ukukhutshwa kwenguqulelo entsha yomphathi wesikhongozeli I-LXD 5.0 kunye ne-LXCFS 5.0 inkqubo yefayile ebonakalayo, ukuba leli sebe elitsha 5.0 lihlelwe njengenguqu yenkxaso yexesha elide kwaye uhlaziyo luya kwenziwa kude kube nguJuni 2027.
I-LXC isetyenziswa njengexesha lokuqalisa ukuqaliswa njengezikhongozeli. equka ilayibrari ye-liblxc, iseti yezinto eziluncedo (i-lxc-dala, i-lxc-start, i-lxc-stop, i-lxc-ls, njl. njl.), iithempleyithi zokudala izikhongozeli, kunye neseti yezibophelelo kwiilwimi ezahlukeneyo zokucwangcisa. Ukwahlula kwenziwa kusetyenziswa iindlela eziqhelekileyo zeLinux kernel.
Indlela yesithuba segama isetyenziselwa ukwahlula iinkqubo, i-ipc, isitakhi sothungelwano se-uts, i-id yomsebenzisi, kunye neendawo zokukhwelisa zamaqela zisetyenziselwa ukunciphisa izibonelelo. Iimpawu zeKernel ezifana neeprofayili ze-Apparmor kunye ne-SELinux, imigaqo-nkqubo ye-Seccomp, i-Chroots (pivot_root), kunye nezakhono zisetyenziselwa ukunciphisa amalungelo kunye nokukhawulela ukufikelela.
Ukongeza kwi-LXC, I-LXD ikwasebenzisa amacandelo asuka kwiprojekthi ye-CRIU ne-QEMU. Ukuba i-LXC yi-toolkit yomgangatho ophantsi wokulawula izikhongozeli zomntu ngamnye kwinqanaba, i-LXD ibonelela ngezixhobo zolawulo oluphakathi kwezikhongozeli ezifakwe kwi-multi-server cluster.
I-LXD iphunyezwa njengenkqubo yangasemva eyamkela izicelo kuthungelwano nge-REST API kwaye ixhasa umva ohlukeneyo wokugcina (umthi we-directory, i-ZFS, i-Btrfs, i-LVM), i-snapshots ecacileyo, imfuduko ephilayo yezikhongozeli ezisebenzayo ukusuka kumatshini omnye ukuya komnye, kunye nezixhobo zokugcina umfanekiso. I-LXCFS isetyenziselwa ukulinganisa izikhongozeli ze-/proc kunye / sys pseudo-FS, kunye nembono ebonakalayo ye-cgroupfs ukwenza izikhongozeli zibukeke njengenkqubo eqhelekileyo yokuma yodwa.
Iindaba eziphambili ze-LXD 5.0
Kolu guqulelo lutsha lwe-LXD 5.0 olubonisiweyo, i ukukwazi ukuplagi eshushu kwaye ukhuphe iidrive ze-USB kunye nezixhobo. Kumatshini obonakalayo, idiski entsha ifunyenwe sisixhobo esitsha esivela kwibhasi ye-SCSI, kwaye isixhobo se-USB sifunyenwe ngokuvelisa isiganeko se-USB hotplug.
Inkqubo ye- ukukwazi ukuqalisa i-LXD nokuba akunakwenzeka ukuseka uqhagamshelwano lwenethiwekhi, umzekelo, ngenxa yokungabikho kwesixhobo senethiwekhi esiyimfuneko. Endaweni yokubonisa imposiso ekuqaliseni, i-LXD ngoku iqalisa iimeko-bume ezininzi kangangoko inakho phantsi kweemeko zangoku, kunye nezinye iimeko-bume eziqala emva kokuba unxibelelwano lwenethiwekhi lusekiwe.
Kwi-LXD 5.0 entsha indima entsha yamalungu eqela: i-ovn-chassis, ejoliswe kumaqela asebenzisa i-Open Virtual Network (i-OVN) kwintsebenziswano yenethiwekhi (ngokwabela indima ye-ovn-chassis, abancedisi banokwabelwa ukuba basebenze njenge-OVN routers).
Olunye utshintsho olwahlukileyo kukuba indlela ephuculweyo yokuhlaziya umxholo wezahlulo zokugcina ziyacetywa. Kwiinguqulelo zangaphambili, uphuculo lubandakanya kuqala ukukhuphela umzekelo wesikhongozeli okanye ulwahlulo, umzekelo ukusebenzisa ukuthumela/ukufumana umsebenzi kwizfs okanye iibtrfs, emva kokuba ikopi eyenziweyo yadityaniswa ngokuqhuba inkqubo yersync.
Ukuphucula ukusebenza kakuhle yohlaziyo lomatshini wenyani, inguqulelo entsha isebenzisa ingqiqo yemfuduko ekwinqanaba eliphezulu, apho ukuba umthombo kunye nabancedisi bendawo basebenzisa iqela elifanayo lokugcinwa, izifinyezo kunye nokuthumela / ukufumana imisebenzi zisetyenziswa ngokuzenzekelayo endaweni ye-rsync.
Olunye utshintsho olwahlukileyo:
- Ingqiqo yokuchongwa kokusingqongileyo kwilifu-init yenziwe ngokutsha: i-UUID ngoku isetyenziswa njengee-ID zomzekelo endaweni yamagama okusingqongileyo.
- Inkxaso eyongeziweyo yokudibanisa umnxeba wenkqubo ye-sched_setscheduler ukuvumela izikhongozeli ezingenalungelo ukuba zitshintshe izinto eziphambili zenkqubo.
- Iphunyeziwe lvm.thinpool_metadata_size ukhetho lokulawula ubungakanani bemetadata kwi-thinpool.
- Uyilo ngokutsha lwefomathi yolwazi lwenethiwekhi ye-lxc. Inkxaso eyongeziweyo yokudibanisa ujongano, iibhulorho zenethiwekhi, ii-VLAN, kunye nee-OVN.
- Iimfuno ezongeziweyo zeenguqulelo zecandelo elincinci: Linux kernel 5.4, Go 1.18, LXC 4.0.x kunye ne-QEMU 6.0.
- I-LXCFS 5 yongezelela inkxaso yolawulo lweqela elidibeneyo (cgroup2), iphunyezwe /proc/slabinfo kunye /sys/devices/system/cpu, kwaye isetyenziswe i-meson toolkit yokuhlanganisa.
Okokugqibela, ukuba unomdla wokwazi okungakumbi ngayo, unokujonga iinkcukacha Kule khonkco ilandelayo.
