Dezvoltatorii proiectului Fedora au anun\u021bat<\/a><\/noindex> despre \u00eenceput testare<\/a><\/noindex> prima versiune preliminar\u0103 a noii edi\u021bii a distribu\u021biei Fedora CoreOS<\/a><\/noindex>, care a \u00eenlocuit produsele Fedora Atomic Host \u0219i CoreOS Container Linux ca o solu\u021bie unic\u0103 pentru lansarea mediilor bazate pe containere izolate.<\/p>\n

Din CoreOS Container Linux, care a trecut<\/a><\/noindex> a ajuns \u00een m\u00e2inile Red Hat dup\u0103 achizi\u021bia companiei CoreOS, \u00een Fedora CoreOS au fost migrate instrumentele de desf\u0103\u0219urare (sistem de configurare la etapa de bootare Ignition), mecanismul de actualiz\u0103ri atomice \u0219i filosofia general\u0103 a produsului. Din Atomic Host au fost transferate tehnologia de lucru cu pachete, suportul pentru specifica\u021biile OCI (Open Container Initiative) \u0219i mecanisme suplimentare de izolare a containerelor bazate pe SELinux. Con\u021binutul Fedora CoreOS este format pe baza repository-urilor Fedora utiliz\u00e2nd rpm-ostree. Ca runtime-uri suportate \u00een Fedora CoreOS pentru containere sunt declarate Moby (Docker) \u0219i podman. Pentru orchestrarea containerelor deasupra Fedora CoreOS se preconizeaz\u0103 asigurarea suportului pentru Kubernetes. <\/p>\n

Proiectul vizeaz\u0103 oferirea unui mediu minim, actualizat automat f\u0103r\u0103 interven\u021bia administratorului \u0219i unificat pentru desf\u0103\u0219urarea \u00een mas\u0103 a sistemelor server, destinate exclusiv pentru rularea containerelor. Fedora CoreOS con\u021bine doar un set minim de componente, suficient pentru a rula containere izolate \u2014 nucleul Linux, managerul de sistem systemd \u0219i un set de servicii auxiliare pentru conectarea prin SSH, gestionarea configura\u021biei \u0219i instalarea actualiz\u0103rilor. <\/p>\n

Parti\u021bia de sistem este montat\u0103 \u00een modul doar pentru citire \u0219i nu se schimb\u0103 \u00een timpul func\u021bion\u0103rii. Configura\u021bie<\/a><\/noindex> este transmis\u0103 \u00een etapa de bootare cu ajutorul instrumentului Ignition (alternativa Cloud-Init).
\nDup\u0103 ce sistemul a fost lansat, modificarea configura\u021biei \u0219i con\u021binutului directorului \/etc nu este posibil\u0103, este permis\u0103 doar schimbarea profilului de set\u0103ri \u0219i utilizarea acestuia pentru \u00eenlocuirea mediului. \u00cen general, lucrul cu sistemul seam\u0103n\u0103 cu lucrul cu imaginile containerelor, care nu sunt actualizate pe loc, ci reconstruite de la zero \u0219i lansate din nou.<\/p>\n

Imaginea de sistem nu poate fi \u00eemp\u0103r\u021bit\u0103 \u0219i este creat\u0103 folosind tehnologia OSTree (pachetele separate nu pot fi instalate \u00eentr-un astfel de mediu, este posibil doar s\u0103 reconstruie\u0219ti \u00eentreaga imagine a sistemului, extinz\u00e2nd-o cu noi pachete prin intermediul instrumentului rpm-ostree). Sistemul de actualiz\u0103ri se bazeaz\u0103 pe utilizarea a dou\u0103 parti\u021bii de sistem, una fiind activ\u0103 iar cealalt\u0103 folosit\u0103 pentru copierea actualiz\u0103rilor; dup\u0103 instalarea actualiz\u0103rilor, parti\u021biile \u00ee\u0219i schimb\u0103 rolurile. <\/p>\n

Sunt oferite trei ramuri independente Fedora CoreOS:
\n testing cu snapshot-uri bazate pe versiunea curent\u0103 Fedora cu actualiz\u0103ri; stable \u2014 ramura stabilizat\u0103, format\u0103 dup\u0103 dou\u0103 s\u0103pt\u0103m\u00e2ni de testare a ramurii testing; next \u2014 snapshot-ul versiunii viitoare aflate \u00een dezvoltare. Pentru toate cele trei ramuri se creeaz\u0103 actualiz\u0103ri pentru eliminarea vulnerabilit\u0103\u021bilor \u0219i a erorilor grave. \u00cen aceast\u0103 etap\u0103 de dezvoltare, \u00een cadrul lans\u0103rii preliminare, se formeaz\u0103 doar ramura testing. Prima lansare stabil\u0103 este planificat\u0103 s\u0103 aib\u0103 loc \u00een 6 luni. Suportul pentru distribu\u021bia CoreOS Container Linux va fi \u00eencheiat cu 6 luni dup\u0103 stabilizarea Fedora CoreOS, iar \u00eencheierea suportului pentru Fedora Atomic Host este a\u0219teptat\u0103 la sf\u00e2r\u0219itul lunii noiembrie.<\/p>\n

Dup\u0103 stabilizarea proiectului, trimiterea de telemetrie va fi activat\u0103 implicit (\u00een versiunea preliminar\u0103, telemetria este \u00eenc\u0103 inactiv\u0103) prin utilizarea serviciului fedora-coreos-pinger, care colecteaz\u0103 periodic \u0219i trimite c\u0103tre serverele proiectului Fedora informa\u021bii despre sistem care nu pot duce la identificare, cum ar fi num\u0103rul versiunii OS, tipul de platform\u0103 cloud, metoda de instalare. \u00cen datele transmise nu sunt incluse informa\u021bii care pot duce la identificare. Statisticile sunt analizate folosind doar date agregate, care permit evaluarea general\u0103 a modului \u00een care este utilizat Fedora CoreOS. Utilizatorul poate dezactiva trimiterea de telemetrie sau extinde informa\u021biile transmise implicit.<\/p>\n
