Abathuthukisi beFedora umemezele ukukhishwa kwenguqulo yokuqala ezinzile ye- ukusatshalaliswa I-Fedora CoreOS ukusetshenziswa okujwayelekile. IFedora CoreOS inyuswa njenge Isixazululo esiyingqayizivele sezikhathi zokuqalisa ezisuselwa esitsheni, esikhundleni semikhiqizo yeFedora Atomic Host kanye nemikhiqizo yeCoreOS Container Linux.
I-Fedora CoreOS ihlose ukuhlinzeka ngemvelo encane, evuselelwe i-athomu ngaphandle kokubamba iqhaza komlawuli futhi okuhlanganisiwe ekusetshenzisweni okukhulu kwezinhlelo zeseva ezenzelwe kuphela ukuqhuba iziqukathi.
Mayelana neFedora CoreOS
Iphakheji yokusabalalisa inikeza kuphela isethi ephansi yezinto eyanele ukusebenzisa iziqukathi ezingazodwa: i-Linux kernel, imenenja yohlelo ehleliwe, kanye neqoqo lezinsizakalo zokuxhuma nge-SSH, ukuphatha izilungiselelo, nokufaka izibuyekezo.
Ukwahlukanisa kwesistimu kufakwe kumodi yokufunda kuphela futhi ayiguquki ngesikhathi sokusebenza. Ukucushwa kudluliselwa esigabeni sebhuthi kusetshenziswa i-Ignition Toolkit (enye indlela ye-Cloud-Init).
Lapho uhlelo seluqalile, akunakwenzeka ukushintsha izilungiselelo futhi sigcwalise isiqondisi / njll, kuvunyelwe kuphela ukuguqula iphrofayili yokumisa futhi siyisebenzise ukufaka indawo yemvelo. Ngokuvamile, ukusebenza nohlelo kufana nokusebenza nemifanekiso yesitsha engabuyekezwa endaweni, kodwa eyakhiwe kabusha kusuka ekuqaleni futhi yaqala kabusha.
Isithombe sesistimu asihlukaniseki futhi sakhiwa kusetshenziswa ubuchwepheshe be-OSTree (Awukwazi ukufaka amaphakheji ngamanye endaweni enjalo, ungakha kuphela sonke isithombe sesistimu, usikhulise ngamaphakeji amasha usebenzisa amathuluzi we-rpm-ostree).
Uhlelo lokuthuthukisa lususelwa ekusetshenzisweni kwezingxenye ezimbili zohlelo, okukodwa okusebenzayo futhi okwesibili kusetshenziselwa ukukopisha isibuyekezo, ngemuva kokufaka isibuyekezo, izigaba zishintsha izindima.
Kusuka ku-Atomic Host, ubuchwepheshe bokusebenza namaphakeji budlulisiwe, ukusekelwa kokucaciswa kwe-OCI (Open Container Initiative) kanye nezinqubo ezengeziwe zokuhlukaniswa kweziqukathi ze-SELinux. Ngokuzayo, kuhlelwe ukuhlinzeka ukuhlanganiswa namaKubernetes (noma asuselwa ku-OKD) ukuhlela iziqukathi kuFedora CoreOS.
Yini okusha kunguqulo ezinzile
Uhlobo lokuqala oluzinzile lweFedora CoreOS kusekelwe ezinqolobaneni zeFedora 31 usebenzisa iphakethe le-rpm-ostree, kufaka phakathi i-Linux 5.4 kernel, umphathi wesistimu uhlelo lwe-243 nekhithi yamathuluzi I -gnization 2.1.
Kusuka esikhathini sokuqalisa iziqukathi ziyahambisana neMoby 18.09 (Docker) kanye ne-podman 1.7. Ngephutha, cgroups v1 ukwesekwa kunikwe amandla ukuhambisana, kepha ama-cgroups v2 anikwe amandla ngokuzikhethela.
Ikhono lokufaka kuzingxenyekazi ezahlukahlukene lisetshenzisiwe, kufaka phakathi amaseva ajwayelekile, i-QEMU, i-OpenStack, i-VMware, i-AWS, i-Alibaba, i-Azure, ne-GCP.
Kunikezwa izakhiwo ezintathu ezimele zeFedora CoreOS, okwenziwa izibuyekezo ngokususwa kobuthakathaka namaphutha amakhulu:
- ukuhlola ngezifinyezo kususelwa enguqulweni yamanje yeFedora ngezibuyekezo.
- Isitebele: igatsha elizinzile elakhiwe ngemuva kwamasonto amabili lokuhlola igatsha lesivivinyo.
- Okulandelayo - Isifinyezo sokukhishwa kwesikhathi esizayo entuthukweni (kuze kube manje kuphela ezinhlelweni).
Kuzinhlelo zesikhathi esizayo, ukufakwa kokuthunyelwa kwe-telemetry kuyashiwo ku-Fedora CoreOS usebenzisa insiza ye-fedora-coreos-pinger, eqoqa njalo futhi ithumele imininingwane yohlelo engakhombi kumaseva wephrojekthi weFedora, njengenombolo yenguqulo yohlelo lokusebenza, ipulatifomu lamafu, uhlobo lokufakwa.
Phakathi kwemininingwane ethunyelwayo ayikho imininingwane engaholela ekuhlonzweni. Lapho uhlaziya izibalo, kusetshenziswa imininingwane ehlanganisiwe kuphela, esivumela ukuthi senze isinqumo esijwayelekile mayelana nokusetshenziswa kweFedora CoreOS.
Uma ufisa, umsebenzisi angakhubaza ukuthumela i-telemetry noma anwebe imininingwane ezenzakalelayo.
Landa bese uthola i-Fedora CoreOS
Ekugcineni, kulabo abanentshisekelo yokuhlola uhlelo, kufanele bazi ukuthi isithombe se-ISO esinikeziwe singasebenza kwimodi ebukhoma nomthwalo ku-RAM nokuthi kusekelwa nenethiwekhi ebhuthini ngePXE.
Isithombe singatholakala kusuka kusixhumanisi esingezansi.
