Umthathi-nxaxheba uza kwikhosi okanye kwikhosi enzulu. Ubona imiqolo elungeleleneyo yenkxaso yobugcisa, iintambo zombane ezihamba kakuhle, ibhodi yokukhangela yeholo yokufundisa, imifanekiso eqaqambileyo kunye nemizobo yeslayidi. Izithethi ezihlekisayo kunye noncumo zinika ulwazi ngendlela yokuba ube nexesha lokuyiqonda. Izitendi zisekiwe, imisebenzi yokuziqhelanisa ibhabha nje isuka kwiminwe yakho, ngaphandle kokuba ngamanye amaxesha ufuna uncedo lwabasebenzi bezobugcisa. inkxaso.
Kwaye ikhefu lekofu kunye nabantu abanengqondo efanayo, umoya ovuyayo kunye namandla, ukutshintshiselana ngamava, eyona mibuzo ingalindelekanga kwizithethi. Zombini iimpendulo kunye nolwazi ongayi kufumana kwiincwadana, kodwa kuphela ekusebenzeni.
Ucinga ukuba lingakanani ixesha, umzamo kunye nemithambo-luvo ukuze ibukeke ngolu hlobo?
Enkosi kuVolodya Guryanov, umlawuli oqinisekisiweyo we-Kubernetes kunye nenjineli / iqela elikhokelayo e-Southbridge, oye wangqina kwaye wathatha inxaxheba ekudalweni kwezifundo ezininzi ze-Slurm kwasekuqaleni.
Wabona ubunzulu bekhondo lendalo-iintsonkotha kunye neerakhi ezinameva, ukuqonda kunye nezisombululo ebezingalindelekanga. Kwaye sele iqhelekile i-Kubernetes intensives, njenge-Slurm Basic kunye ne-Slurm Mega. Kwaye ikhosi entsha, ehlaziywe kakhulu , esondela ngokungenakuthintelwa neza kuqalisa ngoAgasti 19.
Kodwa, mhlawumbi, ngokwaneleyo amazwi, masiqhubele phambili kwibali ngokwalo. Njani ukusuka kwizihloko ezimbalwa ezinzulu ukuzimela ngokupheleleyo kunye nezinto ezininzi . Ke ndiza kuqalisa ibali lendlela iikhosi ezidalwa kwaye ziphuhliswa ngayo - nje "Kudala kumnyele kude, kude ..."
Yintoni esemva?
Ukuba ubuza ukuba sizenza njani izifundo kwaye ziqala phi zonke, ndiza kuphendula ngokulula "Konke kuqala ngombono."
Ngokwesiqhelo umbono uvela ndaweni ithile- asihlali sibotshwe izandla kwigumbi elingaphantsi de size: "Sisiphi isihloko ekufuneka senze kuso ikhosi?" Iingcamango zivela kwindawo ethile ngokwazo kwimithombo yangaphandle. Ngamanye amaxesha abantu baqala ukubuza ngenkuthalo: "Wazi ntoni malunga nobuchwephesha obuthile?" Okanye kwakunjani ngo-Docker ukuba akunakwenzeka ukuba amlingane kwixesha lekhosi enzulu - ngokucacileyo kwafuneka akhutshelwe ngaphandle ukuze abe nexesha lokuthetha into ngexesha lesifundo esinzulu.
Le yindlela evela ngayo ingcamango.
Emva kokuba kubhengezwe, ngokombono wam, umzuzu onzima kakhulu uqala-ukuqonda ngokubanzi ukuba kufakwe ntoni kule khosi - oku kuthelekiswa kakhulu nendlela izithethi ezilungiselelwe ngayo naziphi na iinkomfa.
Kukho enye intlungu ephambili xa ubonakala ukhethe isihloko kwaye ucinge: "Yintoni endinokuxelela ngayo? Oku kulula kakhulu, oku kucacile, wonke umntu uyayazi le nto. β
Kodwa enyanisweni oku akunjalo konke konke. Kwaye mna ngokwam nditsho kwiindawo ezininzi ukuba oko kubonakala kucacile kuwe, kwabo beza kukuphulaphula okanye ukuthatha ikhosi, akubonakali kwaphela. Kwaye nanku uluhlu olunjalo lomsebenzi kunye nokungquzulana kwangaphakathi kuvela, malunga nokuba yintoni enokubandakanya kwikhosi. Ngenxa yoko, sifumana uluhlu olunjalo lwezahluko ezinemivimbo emikhulu, ukuba iya kuba yintoni ikhosi.
Kwaye ke umsebenzi olula wesiqhelo uqala:
- Ukukhethwa kwezinto
- Funda ngononophelo uxwebhu lwenguqulo yangoku, ekubeni ihlabathi le-IT ngoku liphuhlisa uhlobo oluthile lwesantya se-cosmic. Nangona usebenza nento kwaye wenze ikhosi malunga nayo, kufuneka uye kumaxwebhu kwaye ubone into entsha apho, yintoni enomdla ukuthetha ngayo, yintoni enokuba luncedo ngakumbi ukuyikhankanya.
- Kwaye i-skeleton ethile yekhosi ibonakala, apho uninzi lwezihloko, ngokubanzi, sele zigutyungelwe kwaye kubonakala ngathi nantoni na ekhoyo - ukurekhoda iividiyo kwaye uqalise kwimveliso.
- Kodwa ngokwenene, hayi, ngoko umsebenzi onzima uqala, kodwa kungekhona kubabhali bekhosi, kodwa kwabo bavavanyayo. Ngokwesiqhelo abavavanyi bethu be-alpha bayinkxaso yobugcisa, ethi, okokuqala, ivavanye iikhosi zazo naziphi na iimpazamo zolungelelwaniso kunye negrama. Okwesibini, basibetha kabuhlungu ngeentonga kwaye bashwabula xa kukho iindawo ezingacacanga ngokupheleleyo, ezingaqondakaliyo. Xa izivakalisi ezingaphantsi ezibunjwe ngokuntsokothileyo ezithatha amaphepha ambalwa okanye ubuvuvu obucacileyo buvela kwizicatshulwa. Bayifunda yonke, bayijonge.
- Emva koko inqanaba lovavanyo lokuziqhelanisa liqala, apho ezinye izinto ezingabonakaliyo ezingasebenziyo nazo zibanjwe kwaye ezinye iingongoma zibonisiwe ezinokuthi zenziwe zibe nzima ngakumbi, kuba ziba nzima kakhulu - ukuhlala nje kunye nokukopisha - kunye neendawo ezichongiweyo apho kakhulu. kunzima kwaye kuninzi ekufuneka sikwenzile sifuna kubantu abazakuthatha esi sifundo. Kwaye ke iingcebiso ziyeza: "Bafo, yenza kube lula apha, kuya kuba lula ukuyiqonda kwaye kuya kubakho inzuzo enkulu kuyo."
- Emva kokuba lo msebenzi ugqityiwe, inxalenye ehambelana nevidiyo ibhaliwe, yonke into ibonakala ilungile. Kwaye unako ukunikela ngayo kwimveliso, ukuthengisa le khosi. Kodwa kwakhona, hayi, kusekude kakhulu - kuba kutshanje siyekile ukuzithemba kancinci kwaye, ngokomgaqo, siqale ukusebenza ngakumbi ngempendulo. Kukho into efana novavanyo lwe-beta - oku kuxa abantu bemenywa kubantu bangaphandle, abangaqhagamshelwanga nenkampani yethu nangayiphi na indlela, kwaye kwezinye izinto ezintle baboniswa zonke iinxalenye zekhosi, iividiyo, umbhalo, imisebenzi ephathekayo, ukuze ukuvavanya umgangatho wezinto eziphathekayo, ukufikeleleka komxholo kwaye wasinceda ukuba senze ikhosi ibe mnandi kangangoko kunokwenzeka.
- Kwaye xa uphindaphindo olunjalo ludlula, izithethi, uvavanyo lwe-alpha ngohlobo lwenkxaso yobugcisa, uvavanyo lwe-beta, uphuculo. Kwaye ke yonke into iqala kwakhona - inkxaso yobugcisa, uvavanyo lwe-beta, ukuphuculwa.
- Kwaye kwinqanaba elithile, ukuqonda kuza ukuba mhlawumbi senziwe ngokuguqulwa, kuba akukho ngqiqweni ngokupheleleyo ukuqinisekisa ukuba wonke umntu uyayithanda, okanye ezinye izigqibo ezinzima zenziwe. Xa amagqabantshintshi amaninzi kwiindawo ezithile abalulekile, phinda uwaphinde kwihlabathi, kuba kukho into engahambi kakuhle.
- Emva koko kufika ixesha lokuhlelwa okuncinci - kwenye indawo isivakalisi asiqulunqwanga kakuhle kakhulu, kwindawo ethile umntu akayithandi ifonti, 14,5, kodwa angathanda 15,7.
- Xa olu hlobo lwezimvo luhlala, ke yiloo nto, ikhosi engaphezulu okanye engaphantsi ivula, ukuthengisa okusemthethweni kuqala.
Kwaye ekuqaleni, umsebenzi omfutshane kunye olula wokwenza ikhosi ujika ungabi lula kwaye uthatha ixesha elide kakhulu.
Kwaye kukho enye ingongoma ebalulekileyo yokuba ukusebenza kunye nekhosi akupheli xa ikhosi ikhutshwa. Okokuqala, siwafunda ngenyameko amagqabaza ashiywe kwiindawo ezithile. Kwaye nangona zonke iinzame esizenzileyo, ezinye iimpazamo zisachongwa, ezinye iimpazamo ziyalungiswa kwaye ziphuculwe endleleni, ngexesha lokwenyani, ukuze umsebenzisi ngamnye olandelayo afumane inkonzo engcono.
Ikhosi nganye inomnikazi wayo wemveliso, owathi, ukongeza ekuchazeni ingcamango jikelele, uhlola imihla ebekiweyo, wenza amanqaku emideni ukuba xa kufika ixesha lokubhala kwakhona ikhosi ngokupheleleyo, kwaye ngokuqinisekileyo kuya kufika, kuba kwiminyaka emibini, okanye emva konyaka, ezinye zezinto esizixelelayo aziyi kuba namsebenzi ngenxa nje yokuba ziya kuphelelwa. Umnini wemveliso wenza amanqaku emideni ukuba abantu abaninzi badla ngokubuza ukuba zeziphi iingongoma ezingacacanga, yiyiphi imisebenzi ebonakala inzima kakhulu, kwaye ebonakala ngathi, ngokuchaseneyo, ilula kakhulu. Kwaye konke oku kuthathelwa ingqalelo xa urekhoda kwakhona ikhosi, ngexesha lohlobo oluthile lokuhlaziya, ukuze ukuphindaphindwa kwekhosi yehlabathi kube ngcono, kulunge ngakumbi kwaye kukhululeke.
Zivela ngolu hlobo izifundo.
Yazalwa njani ikhosi yeDocker
Esi sisihloko esahlukileyo kwaye esingaqhelekanga kuthi. Kuba kwelinye icala, asizange sicwangcise ukuyenza, kuba uninzi lwezikolo ezikwi-Intanethi ziyabonelela. Ngakolunye uhlangothi, yena ngokwakhe wacela inkululeko kwaye wafumana indawo enengqiqo kwingcamango yethu yokuqeqesha iingcali ze-IT eKubernetes.
Ukuthetha kakhulu kwihlabathi jikelele, ekuqaleni konke kwaqala ngekhosi kwi-Kubernetes, xa yayiqala nje, ngokombono wam, emva kwe-Slurm yokuqala. Siqokelele ingxelo kwaye sabona ukuba abantu abaninzi bafuna ukufunda into eyongezelelweyo malunga neDocker kwenye indawo, kwaye ngokubanzi abaninzi beza kwikhosi esisiseko kwiKubernetes bengazi ukuba yintoni na. .
Ke ngoko, kwi-Slurm yesibini benza ikhosi-okanye kunoko, hayi nekhosi, kodwa benza izahluko ezimbalwa kwiDockers. Apho baxelele ezinye zezinto ezisisiseko, ukuze abantu abeza kwi-intensive bangaziva bevinjwa kwaye baqonde ngokubanzi okwenzekayo.
Kwaye ke iziganeko zaphuhliswa ngoluhlobo. Ubungakanani bezinto eziphathekayo bukhule kwaye bayeka ukufaneleka ngeentsuku ezi-3. Kwaye kwavela umbono osengqiqweni nocacileyo: kutheni singajiki into esiyigubungelayo kwi-Slurm Basic ibe luhlobo oluthile lwekhosi encinci onokuthi uthumele kuyo abantu abafuna ukubukela into ethile malunga neDocker ngaphambi kokuthatha ikhosi enzulu eKubernetes.
I-Slurm Junior, enyanisweni, yindibaniselwano yezifundo ezininzi ezisisiseko. Ngenxa yoko, ikhosi yeDocker yaba sisiqwenga seSlurm Junior. Oko kukuthi, eli linyathelo elingu-zero ngaphambili ΠΈ . Kwaye ke kwabakho nje izithintelo ezisisiseko kakhulu.
Ngaxa lithile, abantu baqala ukubuza: βBafo, konke oku kuhle, kwanele ukuqonda ukuba uthetha ngantoni kwiikhosi ezinzulu. Ndingayifunda phi iinkcukacha ezithe vetshe malunga nokuba yintoni i-docker enokuyenza kunye nendlela yokusebenza ngayo, kwaye yintoni? " Ngoko kwavela ingcamango yokuyenza iqonde , ukuze, okokuqala, abantu abeza kwi-Slurm besebenzisa i-Kubernetes banokuthunyelwa kuyo, kwaye ngakolunye uhlangothi, kwabo bangenamdla kwi-Kubernetes kweli nqanaba lophuhliso. Ukuze ingcali ye-IT ize kubukela ikhosi yethu kwi-Docker kwaye iqale indlela yayo yendaleko ngokulula ngeDocker esulungekileyo. Ke ukuze sibe nekhosi epheleleyo, epheleleyo-kwaye ke abaninzi, beyibukele le khosi, besebenze ixesha elithile kunye ne-Docker ecocekileyo, bakhule ukuya kwinqanaba apho bafuna i-Kubernetes okanye enye inkqubo ye-orchestration. Kwaye beza kuthi ngokukodwa.
Ngamanye amaxesha umbuzo uyabuzwa: "Luhlobo luni lwabantu ngoku olunokungadingi uKubernetes?" Kodwa lo mbuzo awukho malunga nabantu, kodwa ngumbuzo malunga neenkampani. Apha kufuneka uqonde ukuba i-Kubernetes ineemeko ezithile apho ifaneleka kakuhle kunye nemisebenzi eyisombulula kakuhle, kodwa ngokuchaseneyo, kukho iimeko ezithile zokusebenzisa i-Kubernetes xa ibangela intlungu eyongezelelweyo kunye nokubandezeleka okongezelelweyo. Ke ngoko, ayixhomekekanga nakubantu, kodwa ukuba zeziphi iinkampani eziphuhlisayo kwaye ixesha elingakanani.
Umzekelo, enye i-monolith yeLifa eyoyikisayo - awufanelanga uyityhale kwi-Kubernetes, kuba iya kubangela iingxaki ezininzi kunezibonelelo. Okanye, umzekelo, ukuba le projekthi encinci, inomthwalo omncinci okanye, ngokomgaqo, ayikho imali eninzi kunye nezibonelelo. Akukho sizathu sokuyitsalela kwi-Kubernetes.
Kwaye ngokubanzi, mhlawumbi, ngokubanzi, njengoko abantu abaninzi sele betshilo, ukuba ubuza umbuzo: "Ngaba ndiyayidinga i-Kubernetes?", ngoko kunokwenzeka ukuba awuyidingi. Andikhumbuli ukuba ngubani owaqala ukuza nayo, ngokombono wam, uPasha Selivanov. Ndiyavumelana noku 100%. Kwaye kufuneka ukhule ukuya ku-Kubernetes - kwaye xa sele sele icacile ukuba ndifuna i-Kubernetes kunye nenkampani yethu iyayidinga, kwaye iya kunceda ukusombulula imiba enjalo kunye nenjalo, ngoko kuya kuba sengqiqweni ukuya kufunda kwaye ufumanise indlela yokuseta. it up kakuhle, ukwenzela ukuba inkqubo yokutshintshela kwi-Kubernetes ayibuhlungu kakhulu.
Ezinye izigulo zabantwana kunye nezinye izinto ezilula, kwaye ezingezizo ezilula kakhulu, zinokufunyanwa ngokukodwa kuthi, kwaye ungahambi ngerake kunye neentlungu zakho.
Iinkampani ezininzi zihambe kanye ngale ndlela ekuqaleni bekukho uhlobo oluthile lweziseko ngaphandle kokufakwa kwezinto. Emva koko bafikelela kwinqanaba lokuba kube nzima ukuyilawula yonke, batshintshela kwi-Docker kwaye ngaxa lithile bakhula bada bafika kwindawo apho yaxinana ngaphakathi kwesakhelo se-Docker kunye nento ayinikezelayo. Kwaye baqala ukujonga into eyayijikeleze, zeziphi iinkqubo ezisombulula ezi ngxaki, kwaye ngokukodwa i-Kubernetes - le yenye yezo nkqubo ezikuvumela ukuba ucombulule iingxaki xa i-Docker ecocekileyo iba yingxushungxushu kwaye ingasebenzi, le yimeko entle ngokwenene xa abantu. Bahamba ngesinyathelo ngesinyathelo ukusuka ezantsi ukuya phezulu, baqonde ukuba le teknoloji ayanele kwaye ihambela kwinqanaba elilandelayo. Basebenzisa into ethile, yaphinda yanqaba, kwaye baqhubela phambili.
Olu khetho lunengqondo-kwaye lupholile kakhulu.
Ngokubanzi, ndiyabona ukuba inkqubo yethu yakhiwe kakuhle kakhulu, umzekelo, , nangeekhosi zevidiyo. Emva koko emva kwe-docker iyahamba ngoko ngoko . Yonke into ihambelana nengqiqo-umntu uyapasa kwaye kuvela umsebenzi oqinileyo.
Ngokomgaqo, iseti yeekhosi ikuvumela ukuba uhlawule amatyala amaninzi, kunye nanamhlanje. Kusekho iindawo ezisasele ziyi-grey, ndiyathemba ukuba kungekudala siza kudala ezinye iikhosi eziza kusivumela ukuba sivale ezi grey, ngakumbi, siza kuza nento malunga nokhuseleko. Ngenxa yokuba oku kuya kuba yimfuneko kakhulu.
Ngamafutshane, sineendawo ezingwevu eziya kuba mnandi kakhulu ukuvala, ukuze kube ngumfanekiso opheleleyo, opheleleyo - kwaye abantu banokuza, kwaye njengeKubernetes ngokwayo ifana nomakhi weLego, unokwenza izinto ezahlukeneyo ukusuka. kuqokelela, ukuba kusekho okwaneleyo - ukongeza, okufanayo kunye nezifundo zethu, ukuze abantu baqonde into abayifunayo kule nto; kufuneka bahlanganise uhlobo lwephazili, uhlobo lolwakhiwo oluseti kwiikhosi zethu.
Ukuba uzibuza umbuzo ochanekileyo kunye nonyanisekileyo: "Ngubani onokusebenzisa ikhosi ye-Docker esebenzayo ngoku?", emva koko:
- Kubafundi abaqalayo ukungena kuyo.
- Ukuvavanya abasebenzi besebe.
- Ngapha koko, kukho iinkampani ezininzi ezingekasebenzisi nje kuphela i-Docker, kodwa akukho mntu ukhe weva ngetekhnoloji enjalo kwaye, ngokusisiseko, akayazi indlela yokuyisebenzisa. Kwaye ndiyazi iinkampani ezininzi ezinkulu eSt. Ngokukodwa, kwiinkampani ezinjalo, kwiinjineli kwiinkampani ezinjalo, le khosi inokuba nomdla kakhulu, kuba, okokuqala, iya kukuvumela ukuba ugxininise ngokukhawuleza kule teknoloji, kwaye okwesibini, ngokukhawuleza nje ukuba kuvele iinjineli ezininzi eziqonda ukuba zonke isebenza, banokuyizisa kwinkampani kwaye baphuhlise le nkcubeko kunye nale mikhombandlela ngaphakathi kwinkampani.
- Ngokoluvo lwam, le khosi isenokuba luncedo kwabo sele besebenze nedocker, kodwa kuncinci kakhulu nangaphezulu kwisitayile esithi "yenza kube kanye, yenza kabini" - kwaye ngoku baya kusebenzisana ngandlela thile neKubernetes efanayo, kwaye oku. ibeka izibophelelo ezithile kubo, ukuba unolwazi oluthe kratya malunga nokuba yintoni i-docker, indlela yokuyiqhuba, kodwa kwangaxeshanye awuyazi ukuba isebenza njani na ngaphakathi, awuyazi into onokuyenza ngayo. yona kwaye yintoni engcono ukuba ungayenzi, Ke le khosi ifaneleke kakuhle ukucwangcisa kunye nolwazi olunzulu.
Kodwa ukuba unolwazi kwinqanaba: "Andazi ukuba zibhalwa njani iifayile zeDocker ngokuchanekileyo, ndinokucinga ukuba zeziphi iindawo zamagama, zisebenza njani izikhongozeli, ziphunyezwa njani kwinqanaba lenkqubo yokusebenza" - emva koko kukho ngokuqinisekileyo akukho sizathu sokuya kuthi, awuyi kufunda nantoni na entsha kwaye uya kuba lusizi kancinci ngemali kunye nexesha elichithiweyo.
Ukuba siqulunqa ukuba yeyiphi inzuzo ikhosi yethu enayo, ke:
- Sizamile ukwenza le khosi kunye nenani elaneleyo leemeko ezisebenzayo eziya kukuvumela ukuba ungaqondi kuphela inxalenye yethiyori ekhoyo, kodwa nokuqonda ukuba kutheni uyidinga kwaye uya kuyisebenzisa njani kwixesha elizayo;
- kukho amacandelo amaninzi angafane afumaneke naphina - kwaye ngokubanzi akukho mathiriyeli ingako kuwo. Ziyahambelana nokunxibelelana kweDocker kunye nenkqubo yokusebenza, nokuba yahluke kancinci. Zeziphi iindlela uDocker azithathayo kwinkqubo yokusebenza ukuze aphumeze inkqubo yokufaka isikhongozeli - kwaye oku kunika ukuqonda okunzulu malunga nomba wonke wokuqhuba izikhongozeli ngaphakathi kwenkqubo yokusebenza yeLinux. Isebenza njani, inxibelelana njani enye kwenye ngaphakathi kwinkqubo yokusebenza, ngaphandle, njalo njalo.
Le yinkangeleko enzulu ngokwenene kangangokuba iyenzeka kunqabile, kwaye kwangaxeshanye, ngokoluvo lwam, ibaluleke kakhulu. Ukuba ufuna ukuyiqonda kakuhle nayiphi na itekhnoloji kwaye uqonde ukuba ulindele ntoni kuyo, kuya kufuneka ube nombono oqhelekileyo wendlela esebenza ngayo kwinqanaba eliphantsi.
Ikhosi yethu ibonisa kwaye ixela ukuba oku kusebenza njani ngokwembono yenkqubo yokusebenza. Kwelinye icala, zonke iisistim zokufaka isikhongozeli zisebenzisa iindlela zokusebenza ezifanayo. Kwelinye icala, bathatha into ekwinkqubo yokusebenza yeLinux, njengedocker. Ezinye iinkqubo zokufaka isikhongozeli azizange zize nayo nantoni na entsha-bathathe into esele ikwiLinux kwaye babhala nje isiqwenga esifanelekileyo esikuvumela ukuba uyibize ngokukhawuleza, uyiqhube, okanye unxibelelane nayo ngandlela thile. I-Docker efanayo ayiloluhlu olukhulu kakhulu phakathi kwenkqubo yokusebenza kunye nomgca womyalelo, luhlobo oluluncedo oluvumela ukuba ungabhali iikiloton zemiyalelo okanye uhlobo oluthile lwekhowudi ye-C ukwenza isitya, kodwa ukwenza oku ngokungena. imigca emibini kwitheminali.
Kwaye enye into, ukuba sithetha ngokuthe ngqo ngeDocker, yintoni iDocker eyizise ngokwenene kwihlabathi le-IT yimigangatho. Isicelo kufuneka siqaliswe njani, kufuneka sisebenze njani, ziphi iimfuneko zelogi, zithini iimfuno zokulinganisa, ukuqwalasela isicelo ngokwaso.
Ngeendlela ezininzi, i-docker imalunga nemigangatho.
Imigangatho ikwaya kuKubernetes-kwaye kukho imigangatho efanayo kanye; ukuba uyayazi indlela yokuqhuba isicelo sakho kakuhle kwiDocker, ke i-99% yexesha iya kusebenza kanye ngaphakathi kweKubernetes.
Ukuba ufumene unomdla kungekuphela kwindlela eyakhiwe ngayo ikhosi yeDocker, kodwa nakwezinye iikhosi, kodwa unomdla kwikhosi ngokwayo ngokwembono ebonakalayo, ngoko ke.
Siya kuvuya ukukubona!
