Kompania Solo.io, q\u00eb zhvillon produkte p\u00ebr sigurimin e funksionimit t\u00eb sistemeve n\u00eb cloud, mikrosh\u00ebrbimeve, kontejner\u00ebve t\u00eb izoluar dhe llogaritjeve pa server, publikoi nj\u00eb toolkit t\u00eb hapur BumbleBee, i orientuar p\u00ebr thjeshtimin e p\u00ebrgatitjes, shp\u00ebrndarjes dhe nisjes s\u00eb programeve eBPF, q\u00eb ekzekutohen n\u00eb nj\u00eb makin\u00eb virtuale speciale brenda b\u00ebrtham\u00ebs Linux dhe lejojn\u00eb p\u00ebrpunimin e operacioneve rrjet\u00ebsore, kontrollin e aksesit dhe monitorimin e funksionimit t\u00eb sistemeve.

P\u00ebr menaxhimin e programeve eBPF, ofrohet nj\u00eb mjet me stil Docker t\u00eb quajtur «bee», me t\u00eb cilin mund t\u00eb ngarkohet menj\u00ebher\u00eb procesori eBPF q\u00eb ju intereson nga nj\u00eb depo e jashtme dhe t\u00eb ekzekutohet n\u00eb sistemin lokal.

Ndryshe nga BCC (BPF Compiler Collection), n\u00eb BumbleBee nuk kryhet rikonstruim i plot\u00eb i kodit t\u00eb p\u00ebrpunuesve p\u00ebr \u00e7do version t\u00eb kernel-it Linux (BCC p\u00ebrdor kompilimin n\u00eb koh\u00eb reale me Clang p\u00ebr \u00e7do hapje t\u00eb programit eBPF).

BumbleBee \u00ebsht\u00eb nj\u00eb shtres\u00eb mbi libbpf dhe ofron lloje shtes\u00eb p\u00ebr interpretimin dhe paraqitjen automatike t\u00eb t\u00eb dh\u00ebnave, t\u00eb vendosura n\u00eb struktura t\u00eb map-eve standarde p\u00ebr eBPF, si\u00e7 jan\u00eb RingBuffer dhe HashMap. <\/p>\n
P\u00ebr nd\u00ebrtimin e programit p\u00ebrfundimtar eBPF dhe ruajtjen e tij si nj\u00eb imazh OCI, mjafton t\u00eb ekzekutoni komand\u00ebn «bee build skedari_me_kod_emri:version», nd\u00ebrsa p\u00ebr ekzekutimin komand\u00ebn «bee run emri:version».
