Udviklerne af Fedora-projektet at de kun havde to blokke tilbage \/8.<\/a><\/noindex> om starten testning<\/a><\/noindex> den f\u00f8rste pr\u00e6limin\u00e6re version af den nye udgave af distributionen Fedora CoreOS<\/a><\/noindex>, som erstatter produkter som Fedora Atomic Host og CoreOS Container Linux som en samlet l\u00f8sning til k\u00f8rsel af milj\u00f8er baseret p\u00e5 isolerede containere.<\/p>\n

Fra CoreOS Container Linux, som er g\u00e5et videre<\/a><\/noindex> kom til Red Hat efter opk\u00f8bet af CoreOS, er der overf\u00f8rt implementeringsv\u00e6rkt\u00f8jer (konfigurationssystem under opstart Ignition), mekanisme for atomare opdateringer og den overordnede filosofi for produktet til Fedora CoreOS. Fra Atomic Host er der overf\u00f8rt pakkeh\u00e5ndteringsteknologi, support for OCI-specifikationer (Open Container Initiative) og yderligere isolationsmekanismer for containere baseret p\u00e5 SELinux. Indholdet af Fedora CoreOS dannes p\u00e5 baggrund af Fedora-repositorier ved brug af rpm-ostree. Som underst\u00f8ttede runtime-milj\u00f8er for containere i Fedora CoreOS er Moby (Docker) og podman meldt. Der planl\u00e6gges support til Kubernetes for orkestrering af containere oven p\u00e5 Fedora CoreOS. <\/p>\n

Projektet har til form\u00e5l at levere et minimalt milj\u00f8, der atomisk opdateres automatisk uden administratorens indblanding og er ensartet til masseudrulning af serversystemer, der udelukkende er beregnet til at k\u00f8re containere. Fedora CoreOS indeholder kun det minimale s\u00e6t af komponenter, der er tilstr\u00e6kkelige til at k\u00f8re isolerede containere \u2014 Linux-kernen, systemadministratoren systemd og et s\u00e6t tjenesteprogrammer til SSH-forbindelse, konfiguration og installationsopdateringer. <\/p>\n

Systempartitionen monteres i skrivebeskyttet tilstand og \u00e6ndres ikke under drift. Konfiguration<\/a><\/noindex> overf\u00f8res ved opstart ved hj\u00e6lp af Ignition-v\u00e6rkt\u00f8jerne (alternativ til Cloud-Init).
\nN\u00e5r systemet f\u00f8rst er startet, er det ikke muligt at \u00e6ndre konfigurationen og indholdet i mappen \/etc, det er kun tilladt at \u00e6ndre indstillingsprofilen og bruge den til at erstatte milj\u00f8et. Generelt minder arbejdet med systemet om arbejdet med containerbilleder, som ikke opdateres p\u00e5 stedet, men genopbygges fra bunden og startes p\u00e5 ny.<\/p>\n

Systembilledet er ikke opdelt og dannes ved hj\u00e6lp af OSTree-teknologi (individuelle pakker kan ikke installeres i et s\u00e5dant milj\u00f8; det er kun muligt at rekonstruere hele systembilledet og udvide det med nye pakker ved hj\u00e6lp af rpm-ostree v\u00e6rkt\u00f8jet). Opdateringssystemet er baseret p\u00e5 brugen af to systempartitioner, hvor den ene er aktiv, mens den anden bruges til at kopiere opdateringen; efter installationen af opdateringen skifter partitionerne roller. <\/p>\n

Der tilbydes tre uafh\u00e6ngige grene af Fedora CoreOS:
\n testing med snapshots baseret p\u00e5 den aktuelle version af Fedora med opdateringer; stable \u2014 stabiliseret gren dannet efter to ugers test af testing-grenen; next \u2014 snapshot af den under udvikling kommende version. Der udarbejdes opdateringer til alle tre grene for at rette s\u00e5rbarheder og alvorlige fejl. P\u00e5 nuv\u00e6rende udviklingstrin i forbindelse med den tidlige version dannes der kun testing-grenen. Den f\u00f8rste stabile version forventes at blive udgivet om 6 m\u00e5neder. St\u00f8tten til distributionen CoreOS Container Linux vil blive afsluttet 6 m\u00e5neder efter stabiliseringen af Fedora CoreOS, og st\u00f8tten til Fedora Atomic Host forventes at oph\u00f8re i slutningen af november.<\/p>\n

N\u00e5r projektet er stabiliseret, vil sending af telemetri som standard blive aktiveret (i den tidlige version er telemetri endnu ikke aktiv) ved brug af tjenesten fedora-coreos-pinger, som periodisk indsamler og sender ikke-identificerbare oplysninger om systemet til Fedora-projektets servere, s\u00e5som OS version nummer, cloud platform, installations type. Blandt de overf\u00f8rte data er der ingen oplysninger, der kan f\u00f8re til identificering. Ved analyse af statistikken anvendes kun aggregerede oplysninger, der giver et generelt indtryk af brugscharacteren af Fedora CoreOS. Hvis \u00f8nskes kan brugeren deaktivere telemetrisendingen eller udvide de oplysninger, der standard sendes.<\/p>\n
