Kwiintsuku ezimbalwa ezidlulileyo abaphuhlisi beDocker bakhuphe inguqulelo entsha yesoftware yabo ukuza kule inguqulelo 18.09 imele ukuqhubela phambili okubalulekileyo kwinjineli ekhokela ikhonteyina emhlabeni.
Ngale nto intsha ikhutshiweyo yeDocker abaphuhlisi bazise uyilo olutsha kunye neempawu eziphucula ukusebenza kwesikhongozeli kunye nokukhawulezisa ukwamkelwa kulo lonke uhlobo lomsebenzisi weDocker, nokuba ngumphuhlisi, umlawuli we-IT, osebenza ekuqaleni, okanye inkampani enkulu esekwe.
Ezona mpawu ziphambili zeDocker 18.09
I-Docker isanda kukhupha i-18.09 ye-CE kunye ne-EE ngezinto ezininzi ezinomdla kunye nokulungiswa kwe-bug.
Enye yezona zinto ziphambili zikhutshiweyo entsha yile Injini yokwakha ngoku ingasetyenziswa.
Oku injini entsha yokwakha nokupakisha isoftware kusetyenziswa izikhongozeli. Yikhowudi entsha yekhowudi ejonge ukubuyisela ngaphakathi abasebenzi beempawu ezikhoyo zokwakha kwiNjini yeMoby.
Iimpawu ezithile kuhlobo lwe-EE ye-Docker injini ibandakanya:
- Yongeze ukuthotyelwa kwe-FIPS yeWindows Server 2016 kunye neenguqulelo zamva
- Ukunyanzeliswa koMxholo weDocker kwiNjini yeShishini. Oku kuvumela i-Docker Injini- Ishishini ukuba liqhube izikhongozeli ezingatyikitywanga ngumbutho othile.
Kwakhona Kufuneka iqatshelwe into yokuba umthetho omtsha "#syntax" wazisiwe, ovumela ukubandakanywa kohlaziyo lweDockerfile.
Yongeze amandla okusebenzisa i-BuildKit ngaphandle kokubandakanya imo yovavanyo kunye ne-API ehlaziyiweyo kuhlobo lwe-1.39 ifunyenwe.
Ngakolunye uhlangothi, yongeze inkxaso yokufikelela kude usebenzisa i-SSH kunye nomyalelo omtsha "docker engine" ukulawula umjikelo wobomi beNjini yeDocker, ebaleka kwisikhongozeli esizimeleyo esikhethekileyo esisekwe kwisikhonkwane.
Umjikelo wophuhliso owandisiweyo
Nge-Docker 18.09, ixesha lokuxhasa likhulisiwe ukusuka kwi-4 ukuya kwiinyanga ezi-7 ngenxa yokuphuculwa komjikelo wophuhliso loHlelo loLuntu lwaseDocker (Ukukhutshwa okuzinzileyo ngoku akwenziwanga kanye ngekota, kodwa kube kanye kwiinyanga ezintandathu.)
Ukubakho kokudibanisa iimfihlo zexesha lokwakha
Enye yezinto ezintsonkothileyo zokusebenzisa iiDockerfiles ibisoloko ifikelela kwizibonelelo zabucala. Ngokwazi kwam ukuba ufuna ukufikelela kwindawo yokugcina izinto okanye kwinkonzo yabucala, bekungekho elungileyo ukuyiphumeza.
I-Docker 18.09 yomyalelo wokwakha iza nohlaziyo olutsha. Okona kubaluleke kakhulu, ukumiliselwa ngokutsha ngokutsha okubonelelwe yiprojekthi yeMoby BuildKit ngoku inokusetyenziswa.
I-backKit backend iza neqela lezinto ezintsha, enye yazo yinkxaso yokwakha iimfihlo kwiDockerfiles.
Ukuphunyezwa kweemfihlo zokwakha kusekwe kumanqaku amabini amatsha abonelelwe yi-BuildKit. Inye kukukwazi ukusebenzisa imifanekiso elayishwe ngumfanekiso engaphambili kwirejista, kwaye enye sisixhobo sokusebenzisa ii-mounts kwiRUNcommands yeeDockerfiles.
Uphuculo lweKhiKit
I-Docker 18.09 ikwabandakanya uyilo olutsha lokwakha ephucula ukusebenza, ukugcinwa kogcino, kunye nokwandiswa, ngelixa usongeza ezinye izinto ezibalulekileyo:
Ukuphuculwa kokusebenza kwe-BuildKit kubandakanya imodeli ehlelwe ngokutsha concurrency kunye ne-caching eyenza ukuba ikhawuleze, ichaneke ngakumbi kwaye iphathekayo.
Umzekelo, xa kuvavanywa iprojekthi yeDockerfile iseti ye-Moby isantya esonyukayo ukusuka kuma-2 ukuya kuma-9,5 amaxesha ngenxa yokumiliselwa ngaxeshanye kwamanqanaba okunyusa amaninzi, ukungahoyi amanyathelo angasetyenziswanga kunye neefayile zedatha ezonyukayo phakathi kweeseti kwimeko yokujonga.
Ukuphunyezwa okutsha kukwaxhasa ezi modeli zintsha zokusebenza:
- Amanqanaba afanayo okwakha
- Tsiba amanqanaba angasetyenziswanga kunye neefayile zomxholo ongasetyenziswanga
- Ukonyusa imeko yokuhambisa phakathi kolwakhiwo
Kwezinye iimpawu ezinokuqaqanjiswa, sifumana:
- Ukuhlaziya igalelo bash kunye ne-zsh iziseko zomyalelo.
- Kongezwe umqhubi omtsha wobhaliso lwasekhaya, evumela ukuba irejista igcinwe kwifayile yendawo. Ngokungafaniyo ne-jsonfilelog, isiphatho esitsha asibophelelekanga kwifomathi ethile yelog.
- Inkxaso eyongeziweyo yokusebenzisa iphuli yedilesi emiselweyo.
- Ngokusekwe kwi-Injini ye-Docker 18.09, imveliso yorhwebo ye-Docker Enterprise 2.1 yasekwa, ebandakanya ukuhanjiswa kweefowuni ezongezelelweyo, inkxaso ye-SLA (isiVumelwano seNqanaba leNkonzo) kunye neendlela zokuqinisekisa ngezisayino zedijithali.
