I-Docker yilokho okwaziwa njengeplatifomu yohlelo lokusebenza lwe-container. Njengesikhulumi, sinikeza abasebenzisi bayo konke okubandakanya ukuphathwa kweziqukathi, kusuka ezimfunekweni eziyisisekelo, njengokubeka izinqubo ezilula eziqukethe iziqukathi, kuzinqubo eziyinkimbinkimbi kakhulu, njengokuhlolwa kwedatha ngesikhathi. yemisebenzi ye-orchestrator.
Ngaleli thuba, iDocker ivuselelwa ngenguqulo yayo engu-1.12, efaka izici eziningi ezintsha, ngenxa yokusebenzisana kwabathuthukisi beplatifomu kanye neminikelo eyenziwe ngumphakathi.
Idokodo 1.12.
Iqembu lezici lifakiwe kuleli thuba lokuveza inketho eyaziwa njenge imodi ye-swarm. Lokhu kuvuleka njengesakhiwo esinama-node ahlanganiswe nohlelo olusabalalisiwe, lapho i-node ngayinye ngokuzimela iyisistimu engenelela ekuphathweni kohlelo jikelele, lokugcina izinsiza. I-node ngayinye ingahlelwa ukuze iqembu noma ezinye zazo zigxile ebuholini bemisebenzi ethile; Leli qembu lisebenza ekuphathweni kweqoqo kanye nemisebenzi efakwa yisiqukathi, kanye nensizakalo enikezwe i-API. nelinye iqembu lama-node ekusebenzeni okusele. Lezaziwa njengezindawo zomsebenzi,tBasebenza ekwenzeni imisebenzi elula nakho konke okubandakanya ukuhamba kwedatha esitsheni. Kubalulekile ukuthi wazi ukuthi njengengxenye yezokuphepha, lezi zinqubo "ezingaholi" zeziqukathi azikwazi ukufinyelela ngokugcwele kulwazi olunikezwa yi-API kanye nendawo yokugcina imininingwane. Kukhawulelwe kuphela ukufeza imisebenzi yabo eyisisekelo nokubika emsebenzini wabo ngamunye.
Kuyaphawuleka ukuthi ama-node anikezwe imisebenzi ethile awagcinwa njalo unomphela lapho, angabelwa kwezinye izindima ngokucushwa. Imvamisa ibizwa ngegama ukwesekwa umuntu ngamunye angakunikeza lapho omunye wabo engakwazi ukufeza indima ayabelwe.
Njengokwesekwa kokuxhumana phakathi kwezindawo, kusetshenziswa imenenja ebasekelayo kulo msebenzi wokuphatha imininingwane. Ama-node abawaqondisa akwenza ngokuvumelana, izenzo ezibandakanya izinsizakalo kanye nemisebenzi esixukwini. Ngamanye amagama, i-node ekhethwe njengomholi isebenza kanjalo ngesikhathi sokuphathwa nokuthathwa kwezinqumo zeziqukathi. Ngemuva kwalokho, le node ephatha futhi enikeze isimo se-node ngayinye ekubhekweni kwayo, iphinde inikeze imininingwane ngemisebenzi nezinsizakalo ezenziwa yibo. La ma-node aphethe ngokulandelana awadingi izimvume ezikhethekile zezinkinobho ezinikeza ukufinyelela kulwazi olushiwo, zisebenza ngaphandle kokuphikisana ngalolu daba, zishiya ukwesekwa okufanele zikunikeze abaholi bezindawo ezisele.
Endabeni yezindawo zokusebenzela, ukuxhumana nezindawo zokuphatha kwenziwa ngokusebenzisal Iphrothokholi ye-GRPC osebenza ngamanethiwekhi I-HTTP / 2. Ngale protocol, banikeza ama-akhawunti kuzindawo zokuphatha zesimo semisebenzi abayabelwe, kanye nesibonakaliso sempilo esibonisa ukuthi ngabe le node iyaqhubeka yini nokusebenzela isitsha.
Ihlokondiba lisebenza njengohlelo olugeleza ngamandla lwenqubo ngayinye, ngenxa yohlelo lwayo lwefayela olusatshalaliswa. Inenkumbulo ye- funda ngokushesha elungiselela lezi zinqubo zokufunda ngezikhathi lapho umthwalo wokufunda uphezulu ngokwedlulele futhi kudingeka ijubane lokufunda eliningi ngalezo zimo. Ngendlela efanayo, i- ukubhala imininingwane ekwakhiweni kwesixuku; ukuqoqa yonke imininingwane kunethiwekhi efanayo, into egcina isikhathi esiningi ngesikhathi sokucela into. Ngokusobala, ukusebenza kahle ekubhalweni nasekufundweni kwedatha kukhulisa kakhulu ijubane nokusebenza, ngaphandle kokubeka phansi ukugcinwa kanye nokugcinwa kwedatha ngesikhathi senqubo.
I-Docker 1.12 ilawula uhlelo lwe-swarm ukuhlinzeka ngokugcinwa kwedatha okusatshalaliswe kahle nokufinyelela okusheshayo kudatha eliqukethe. Ukwenza uhlelo lokufunda olunzulu olubhekela kuphela ukubhala idatha kudiski ngezikhathi ezidingeka kakhulu. Okuthile okunikeza ukusebenza okukhulu kule ndawo kohlelo futhi okungakushiyi eceleni ukuphepha, okutholakala ngaphakathi kweDocker kutholakala kakhulu kulabo abangezona izazi emkhakheni. Kufanele ube nolwazi oluthuthuke kakhulu ezimweni lapho udinga ukuphatha khona ukuphepha kwethrafikhi yembondela, okuvamise ukuthi kudinge ukunakekelwa mathupha noma ukumiswa.
Uma ufuna ukwazi i-Docker eyengeziwe nenguqulo yayo entsha lapha sikushiyela isixhumanisi sayo ibhulogi esemthethweni.
