Virksomheden Solo.io, der udvikler produkter til drift af cloud-systemer, mikroservices, isolerede containere og serverl\u00f8se beregninger, har offentliggjort det \u00e5bne v\u00e6rkt\u00f8j BumbleBee, der sigter mod at forenkle forberedelse, distribution og k\u00f8rsel af eBPF-programmer, der udf\u00f8res i en speciel virtuel maskine inden i Linux-kernen og g\u00f8r det muligt at behandle netv\u00e6rksoperationer, kontrollere adgang og overv\u00e5ge systemfunktioner. Koden er skrevet i Go og distribueres under Apache 2.0-licensen. <\/p>\n
BumbleBee giver mulighed for at pakke eBPF-programmet som et OCI (Open Container Initiative) containerbillede, som kan k\u00f8res p\u00e5 enhver system uden recompilation og brug af ekstra komponenter i brugeromr\u00e5det. Interaktionen med eBPF-koden i kernen, inklusive behandlingen af indg\u00e5ende data fra eBPF-behandlerne, varetages af BumbleBee, som automatisk eksporterer disse data i form af metrikker, histogrammer eller logs, som kan tilg\u00e5s for eksempel ved hj\u00e6lp af curl-v\u00e6rkt\u00f8jet. Den foresl\u00e5ede tilgang g\u00f8r det muligt for udvikleren at fokusere p\u00e5 at skrive eBPF-kode uden at blive distraheret af at organisere interaktionen med denne kode fra brugeromr\u00e5det, kompiliering og indl\u00e6sning i kernen. <\/p>\n
For managing eBPF programs, a Docker-style utility called «bee» is offered, which allows you to load the desired eBPF handler from an external repository and run it on your local system. The toolset enables the generation of a code skeleton in C for eBPF handlers of a selected topic (currently, only handlers for network and file operations are supported, intercepting calls to the network stack and file systems). Based on the generated skeleton, the developer can quickly implement the functionality they are interested in. <\/p>\n
I mods\u00e6tning til BCC (BPF Compiler Collection) kr\u00e6ver BumbleBee ikke en fuldst\u00e6ndig genbygning af behandlerkoden for hver version af Linux-kernen (BCC bruger runtime-kompilation ved hj\u00e6lp af Clang ved hver k\u00f8rsel af eBPF-programmet). For at l\u00f8se problemer med portabilitet udvikles v\u00e6rkt\u00f8jer som CO-RE og libbpf, som g\u00f8r det muligt at kompilere koden \u00e9n gang og bruge en speciel universel loader til at tilpasse det indl\u00e6ste program til den nuv\u00e6rende kerne og BTF-typer (BPF Type Format). BumbleBee er et lag ovenp\u00e5 libbpf og tilbyder ekstra typer til automatisk fortolkning og visning af data, der er placeret i de standard eBPF map-strukturer RingBuffer og HashMap. <\/p>\n
To build the final eBPF program and save it as an OCI image, you just need to execute the command «bee build file_with_code name:version», and to run it, the command «bee run name:version». By default, the events received from the handler will be displayed in the terminal window, but if necessary, you can retrieve data by using curl or wget to connect to the network port associated with the handler. Handlers can be distributed through OCI-compatible repositories; for example, to run an external handler from the ghcr.io repository (GitHub Container Registry), you can execute the command «bee run ghcr.io\/solo-io\/bumblebee\/tcpconnect:$(bee version)». To place the handler in the repository, the command «bee push» is suggested, and for version tagging \u2014 «bee tag». \n Kilde: opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
