Docker chirongwa chakavhurika sosi iyo inoshandura kuendesa kwemaapplication mukati memidziyo yesoftware, ichipa iyo yekuwedzera dura rekushandisa virtualization kubvisa uye otomatiki pane akawanda mashandiro masystem.
Docker inoshandisa zviwanikwa kupatsanurwa maficha eLinux kernel, senge makgroup uye nzvimbo dzemazita kubvumidza yakazvimirira "midziyo".
Nenzira iyi, Docker inopa kuti midziyo iyi inomhanya mukati meimwe Linux muenzaniso, ichidzivirira pamusoro pekutanga nekuchengetedza chaiwo michina.
Linux kernel tsigiro yemazita nzvimbo inosarudzika maonero ekushandisa kwenzvimbo yayo yekushanda.
Kusanganisira maitiro emiti, network, maID mushandisi, uye akaisirwa mafaera masisitimu, nepo kernel cgroups inopa zviwanikwa kusarudzika, kusanganisira CPU, ndangariro, block I / O, uye network.
Nyowani vhezheni yeDocker 18.09
Iyo vhezheni yeiyo Docker Isolated Linux Container Management Toolkit 18.09 inoratidzwa, iyo inopa yakakwira-chikamu API yekugadzirisa midziyo padanho rekuzvipatsanura yemumwe mushandisi.
Docker inobvumidza iwe kuvhura zvekupokana maitiro mune yakasarudzika modhi uye wozotamisa uye kuumbiridza midziyo yakagadzirirwa izvi maitiro kune mamwe maseva, kutora iro rese basa kunze kwekugadzira, kugadzirisa, uye kugadzirisa midziyo.
Kubva paDocker 18.09, iyo yekusunungura nguva yekutsigira yabatsirwa sezvo vagadziri vakawedzera kubva pamwedzi mina kusvika kumwedzi minomwe nekuda kwekuvandudzwa kwenzira yekusimudzira yeDocker Nharaunda Edhisheni.
Imwe yemapoinzi akasimba ekusimbisa yeiyi nyowani Docker kuburitswa ndeyekuti iyo yekumhanyisa nguva yekumhanyisa yemidziyo yakagadziridzwa kune iyo ineererd 1.2 kuburitswa.
Izvi zvakadzikamisa kushandiswa kweiyo gRPC mudziyo manejimendi manejimendi uye nekuona kufambidzana neKubernetes 1.12 chikuva uye nekuvandudza kutsigirwa kwemifananidzo yepasirese yezvivakwa zvakasiyana (yakawanda-arch).
Kune rimwe divi, muDocker 18.09 mukana weiyo nyowani yekuvaka backend yakawedzerwa (inopa mashandiro eiyo "docker kuvaka" rairo). Kuti uite otomatiki mashandiro ekuunganidza marara anotsigirwa neyakavakirwa basa kuvhurwa uye asingade midzi midzi mushandisi mvumo panguva yekushanda.
VakaKit kugadzirisa
Docker 18.09 inosanganisirawo sarudzo yekumisikidza iyo BuildKit. Izvi ichi chivakwa chitsva chekuvaka chinovandudza mashandiro, kuchengetedza manejimendi, uye kuwedzeredza, uku uchiwedzera zvimwe zvakakosha.
Kugadziridza kwekuita: BuildKit inosanganisira yakagadziriswazve concurrency uye caching modhi inoita kuti iwedzere kukurumidza, kunyatsoita, uye kutakurike.
Neshanduko iyi uye kuenderana kwemapurani, futi Vagadziri veDocker ikozvino vanotendera kukwidziridzwa kubva kuCommunity vhezheni injini kuenda kune Injini yeinjini ine nyore rezenisi activation.
Kune vashandisi veazvino veiyo Docker Nharaunda vhezheni, danho iri rinoreva kuvhura akawanda emabhizinesi ekuchengetedza maficha uye kuwana mukana weDocker's bhizinesi-kirasi rutsigiro uye akawedzera maitiro ekuchengetedza.
Kuenzaniswa neshanduro yapfuura
Iyo kodhi yakagadziridzwa kuronga kuenzanirana kuitwa kwebasa uye iyo caching modhi yakachinjwa, izvo zvakaita kuti zvikwanisike kukurumidza kumhanyisa gungano.
Semuenzaniso, pakuyedza chirongwa cheDockerfile Moby seti kumhanyisa yakawedzera kubva pa2 kusvika pa9,5 nguva nekuda kwekuitwa panguva imwe chete kwematanho ekumisikidza akawanda, vachiregeredza matanho asina kushandiswa uye akawedzera mafaira mafaira pakati peseti mukutarisa mamiriro.
Wakawedzera kugona kupinza zvakavanzika muDockerfile uye zvidzivise zvakachengeteka mukati mekuita kwekuvaka, pasina kuzvichengeta mumifananidzo inoguma uye isina kuiswa mune yekuvaka cache.
Iko kugona kutumira ssh ssh-mumiriri zvigadziko, inoitwa, semuenzaniso, kubatanidza kune zvakavanzika zvinyorwa uchishandisa chinongedzo chiripo kuburikidza nessh-mumiriri.
Iye zvino gungano cache inogona kutarisirwa, zvakasiyana nemifananidzo.
Wakawedzera murairo mutsva "docker builder prune" kujekesa cache uye kugona kutsanangura kuchenesa mitemo uye zvimwe.
Kana iwe uchida kuziva zvishoma nezvazvo unogona kushanyira chinotevera chinongedzo.
