I-Docker yiphrojekthi yomthombo ovulekile eyenza ukuthunyelwa kwezinhlelo zokusebenza ngaphakathi kweziqukathi zesoftware, ukuhlinzeka ngesendlalelo esingeziwe sokukhishwa kokusebenza kokuzenzakalela nokuzenzakalelayo kuzinhlelo eziningi zokusebenza.
Docker isebenzisa izici zokuhlukaniswa kwemithombo ye-Linux kernel, njengamaqoqo kanye nezikhala zamagama ukuvumela "iziqukathi" ezizimele.
Ngale ndlela, i-Docker ihlinzeka ukuthi lezi ziqukathi zihamba ngaphakathi kwesimo esisodwa se-Linux, zivikela ngaphezulu kokuqala nokugcina imishini ebonakalayo.
Ukusekelwa kwe-Linux kernel yezikhala zamagama kwehlukanisa ukubuka kohlelo lokusebenza ngemvelo yokusebenza kwayo.
Kubandakanya izihlahla zenqubo, inethiwekhi, ama-ID omsebenzisi, nezinhlelo zamafayela afakiwe, kuyilapho ama-kernel cgroups enikezela ukuhlukaniswa kwemithombo, kufaka phakathi i-CPU, inkumbulo, i-block I / O, nenethiwekhi.
Uhlobo olusha lwe-Docker 18.09
Kuthulwe inguqulo ye-Docker Isolated Linux Container Management Toolkit 18.09, okuyi inikeza i-API esezingeni eliphakeme yokuphatha iziqukathi ezingeni lokuhlukaniswa kwezicelo ngazinye.
I-Docker ikuvumela ukuthi uqalise izinqubo zokuphikisana nemodi yokuhlukanisa bese udlulisa futhi uhlanganise iziqukathi ezenzelwe lezi zinqubo kwamanye amaseva, ukhipha wonke umsebenzi ekwakheni, ekugcineni nasekugcineni iziqukathi.
Kusukela ngo-Docker 18.09, isikhathi sokuxhaswa sokukhishwa siye sazuza njengoba abathuthukisi bekhuphuke besuka ezinyangeni ezi-4 zaya kwezingu-7 ngenxa yesimanje umjikelezo wokuthuthuka we-Docker Community Edition.
Amanye amaphuzu aqinile wokugqamisa lokhu kukhishwa kwe-Docker entsha ukuthi isikhathi sokusebenza esiyisisekelo sokuphathwa kweziqukathi sibuyekeziwe ekukhishweni kwe-container engu-1.2.
Lokhu kuzinzise ukusetshenziswa kwendlela yokuphathwa kweziqukathi ye-gRPC futhi kwaqinisekisa ukuhambisana nesikhulumi seKubernetes 1.12 nokusekelwa okuthuthukisiwe kwezithombe zomhlaba wonke zezakhiwo ezahlukahlukene (i-multi-arch).
Ngakolunye uhlangothi, ku-Docker 18.09 kungenzeka ukuthi kube nokwakhiwa okusha okwengezelelwe okusha (inikeza ukusebenza komyalo we- "docker build"). Ukwenza ngokuzenzakalela imisebenzi yokuqoqwa kukadoti esekelwa ukwethulwa komsebenzi okwakhiwe futhi engadingi igunya lomsebenzisi wezimpande ngesikhathi sokusebenza.
Ukuthuthuka kwe-BuildKit
I-Docker 18.09 ifaka nenketho yokuhlehlisa i-BuildKit. Lokhu ukwakhiwa okusha okwakha ukusebenza, ukuphathwa kwesitoreji, nokwelula, ngenkathi kungezwa ezinye izici ezintsha ezibalulekile.
Ukuthuthuka kokwenza
Ngalolu shintsho nokuqondaniswa kwezakhiwo, futhi Abathuthukisi be-Docker manje bavumela ukuthuthuka kusuka kunjini yenguqulo yoMphakathi kuya enjinini ye-Enterprise ngokusebenza kwelayisense okulula.
Kubasebenzisi bamanje benguqulo ye-Docker Community, lokhu kuhamba kusho ukuvula izici eziningi zokuphepha kwamabhizinisi nokuthola ukufinyelela ekusekelweni kwebhizinisi lakwa-Docker kanye nezinqubomgomo ezinwetshiwe zokulungisa.
Uma kuqhathaniswa nenguqulo yangaphambilini
Ikhodi yaguqulwa ukuhlelela ukwenziwa okufanayo komsebenzi futhi imodeli yokulondolozwa kwesikhashana yashintshwa, okwenze ukuthi kusheshe kakhulu ukusheshisa umhlangano.
Isibonelo, lapho kuvivinywa iphrojekthi ye-Dockerfile Moby isethi yejubane inyuke isuka ezikhathini ezi-2 zaya ku-9,5 ngenxa yokwenziwa ngasikhathi sinye kwezigaba eziningi zokukhuphuka, ukungazinaki izinyathelo ezingasetshenziswanga namafayela wedatha anyukayo phakathi kwamasethi abukwayo umongo.
Kungezwe amandla okushumeka izimfihlo ku-Dockerfile futhi zidlulise ngokuphepha ngesikhathi senqubo yokwakha, ngaphandle kokuzigcina ezithombeni eziholelwayo nangaphandle kokufakwa kunqolobane yokwakha.
Amandla okudlulisa amasokisi we-ssh ssh-agent, kuyenziwa, ngokwesibonelo, ukuxhuma kumakhosombe wangasese usebenzisa ukuxhumana okukhona nge-ssh-agent.
Manje isilondolozi somhlangano singaphathwa, ngokuhlukile kwizithombe.
Kungezwe umyalo omusha "we-docker builder prune" ukusula i-cache kanye nekhono lokuchaza imithetho yokuhlanza nokuningi.
Uma ufuna ukwazi okwengeziwe ngakho ungavakashela isixhumanisi esilandelayo.
