Samuel Karp, ingeni\u00f8r hos Amazon, der besk\u00e6ftiger sig med udviklingen af Linux-distributionen Bottlerocket og containerisoleringsteknologier til AWS, udvikler baseret p\u00e5 jail-omgivelserne i FreeBSD et nyt runtime, runj, til at sikre isoleret k\u00f8rsel af containere, der er tilpasset specifikationen fra OCI (Open Container Initiative). Projektet positioneres som eksperimentelt, udviklet i fritiden fra hovedarbejdet, og befinder sig stadig i prototypefasen. Koden er skrevet i Go og distribueres under BSD-licensen. <\/p>\n

N\u00e5r udviklingen er n\u00e5et til det \u00f8nskede niveau, kan projektet potentielt vokse til at v\u00e6re i stand til at anvende runj som erstatning for det standard runtime i Docker- og Kubernetes-systemer, ved at bruge FreeBSD til at k\u00f8re containere i stedet for Linux. Fra OCI runtime er der i \u00f8jeblikket implementeret kommandoer til oprettelse, sletning, k\u00f8rsel, tvungen afslutning og evaluering af containerens tilstand. Indholdet af containeren er baseret p\u00e5 et standard eller reduceret FreeBSD-milj\u00f8. <\/p>\n

Da der i OCI-specifikationen stadig mangler st\u00f8tte for FreeBSD, er der i projektet udviklet en r\u00e6kke yderligere parametre relateret til konfigurationen af jail og FreeBSD, som planl\u00e6gges sendt til inkludering i den prim\u00e6re OCI-specifikation. For at styre jail bruges v\u00e6rkt\u00f8jerne jail, jls, jexec, kill og ps fra FreeBSD, uden direkte opkald til systemopkald. Fremover n\u00e6vnes tilf\u00f8jelsen af st\u00f8tte til administration af ressourcebegr\u00e6nsninger via RCTL-interfacet i kernen. <\/p>\n

Udover det eget runtime udvikles der i projektets repository ogs\u00e5 et eksperimentelt lag til brug sammen med containerd-runtime (bruges i Docker), modificeret til at underst\u00f8tte FreeBSD. For at konvertere rootfs FreeBSD til et OCI-kompatibelt containerbillede tilbydes et specielt v\u00e6rkt\u00f8j. Det f\u00e6rdige billede kan senere importeres til containerd.
