Umbambiqhaza uza esifundweni noma esifundweni esijulile. Ubona imigqa ehlelekile yokusekelwa kwezobuchwepheshe, izintambo zikagesi ezihamba kahle, ibhodi lokuhlola lehholo lezinkulumo, izithombe ezikhanyayo nemidwebo yama-slide. Izikhulumi ezinamahlaya nokumamatheka zinikeza ulwazi ngendlela yokuthi ube nesikhathi sokukuqonda. Izitendi zimisiwe, imisebenzi yokuzijwayeza imane indize isuke eminweni yakho, ngaphandle kokuthi ngezinye izikhathi udinga usizo lwabasebenzi bezobuchwepheshe. ukusekela.
Futhi ikhefu lekhofi nabantu abanomqondo ofanayo, umoya ojabulisayo nonomdlandla, ukushintshana kokuhlangenwe nakho, imibuzo ebingalindelekile yezikhulumi. Kokubili izimpendulo nolwazi ongeke uluthole kumamanuwali, kodwa ngokusebenza.
Ucabanga ukuthi kwathatha isikhathi esingakanani, umzamo kanye nezinzwa ukuze kubukeke ngale ndlela?
Sibonga uVolodya Guryanov, umlawuli we-Kubernetes oqinisekisiwe kanye nonjiniyela/ohola ithimba e-Southbridge, oye wazibonela waphinde wabamba iqhaza ekwakhiweni kwezifundo eziningi ze-Slurm kusukela ekuqaleni.
Wabona indalo engaphansi—izingqinamba kanye namarasha anameva, ukuqonda kanye nezixazululo ezingalindelekile. Futhi ama-Kubernetes asevele ajwayelekile, afana ne-Slurm Basic kanye ne-Slurm Mega. Nesifundo esisha, esibuyekezwe kakhulu , esisondela ngokungenakuvinjelwa futhi ezoqala ngo-August 19.
Kodwa, mhlawumbe, ngokwanele amazwi, ake siqhubekele endabeni ngokwayo. Kanjani kusuka ezihlokweni ezimbalwa ezijulile a ukuzimela ngokuphelele futhi multifaceted . Ngakho-ke ngizoqala indaba yokuthi izifundo zidalwa futhi zithuthukiswe kanjani - njengokuthi "Kudala emthaleni okude, kude..."
Yini engemuva?
Uma ubuza ukuthi senza kanjani izifundo nokuthi zonke ziqala kuphi, ngizovele ngiphendule "Konke kuqala ngombono."
Ngokuvamile umbono uvela ndawana thize - asihlali siboshwe izandla nezinyawo endaweni engaphansi size siqhamuke: "Yisiphi isihloko okufanele senze isifundo ngaso?" Imibono iphuma endaweni ethile iyodwa emithonjeni yangaphandle. Kwesinye isikhathi abantu baqala ukubuza ngenkuthalo ukuthi: “Wazini ngobuchwepheshe obunjalo nobuthize?” Noma kwenzeka kanjani ngo-Docker ukuthi kungenzeki ukumfaka esikhathini sesifundo esibucayi - kusobala ukuthi bekumele akhishelwe ngaphandle ukuze abe nesikhathi sokukhuluma okuthile ngesikhathi sokufunda.
Uvela kanje umbono.
Ngemva kokumenyezelwa, ngokombono wami, isikhathi esinzima kakhulu siqala - ukuqonda ngokuvamile ukuthi yini okufanele ifakwe kulesi sifundo - lokhu kuqhathaniswa kakhulu nendlela izikhulumi ezilungiselelwa ngayo noma yiziphi izingqungquthela.
Kunobuhlungu obubodwa obukhulu lapho ubonakala ukhethe isihloko bese ucabanga: “Yini engingayitshela ngayo? Lokhu kulula kakhulu, kusobala, wonke umuntu uyakwazi lokhu. ”
Kodwa empeleni akunjalo nhlobo. Futhi mina ngokwami ngithi ezindaweni eziningi lokho okubonakala kusobala kuwe, kulabo abeza ukuzokulalela noma ukuthatha isifundo, akubonakali nhlobo. Futhi lapha ungqimba olukhulu kangaka lomsebenzi kanye nokungqubuzana kwangaphakathi kuvela, mayelana nokuthi yini okufanele uyifake esifundweni. Ngenxa yalokho, sithola uhlu olunjalo lwezahluko ezinemivimbo emikhulu eshanelayo, ukuthi isifundo sizoba ngani.
Bese uqala umsebenzi olula ojwayelekile:
- Ukukhetha okubalulekile
- Funda ngokucophelela imibhalo yenguqulo yamanje, njengoba umhlaba we-IT manje uthuthuka ngohlobo oluthile lwejubane le-cosmic. Ngisho noma usebenza ngokuthile futhi wenze isifundo ngakho, kufanele uye kumadokhumenti futhi ubone ukuthi yini entsha lapho, yini ethokozisayo ukukhuluma ngakho, yini engase ibe wusizo ikakhulukazi ukuyisho.
- Futhi i-skeleton ethile yesifundo ibonakala, lapho izihloko eziningi, ngokuvamile, sezivele zihlanganisiwe futhi kubonakala sengathi noma yini ekhona - qopha amavidiyo futhi uwaqalise ekukhiqizeni.
- Kodwa empeleni, cha, khona-ke umsebenzi onzima uqala, kodwa hhayi kubalobi benkambo, kodwa kulabo abahlolayo. Ngokuvamile abahloli bethu be-alpha bawusekelo lobuchwepheshe, okokuqala, oluhlola amaphutha wezifundo zanoma yimaphi amaphutha okwenziwa kanye nohlelo lolimi. Okwesibili basishaya kabuhlungu ngezinduku nokuthuka inhlamba lapho kukhona izindawo ezingabonakali neze nezingaqondakali. Lapho eminye imisho engaphansi ehlanganiswe ngokuyinkimbinkimbi ehlala amakhasi ambalwa noma umbhedo osobala uyavela emibhalweni. Bayifunda yonke, bayibheke.
- Khona-ke isigaba sokuhlola umkhuba siqala, lapho ezinye izinto ezingabonakali ezingasebenzi nazo zibanjwa futhi amanye amaphuzu akhonjiswa angenziwa abe nzima kakhulu, ngoba akubangeli mnandi kakhulu - ukuhlala nje nokukopisha - futhi kukhonjwa izindawo lapho kukhulu kakhulu. kunzima futhi kuningi esifuna ukukwenza kubantu abazothatha lesi sifundo. Bese kufika izincomo: “Bafo, yenzani kube lula lapha, kuzoba lula ukukubona futhi kuzoba nenzuzo eyengeziwe kukho.”
- Ngemva kokuba lesi samba somsebenzi senziwe, ingxenye ehlobene nevidiyo ibhaliwe, konke kubonakala kuhamba kahle. Futhi usungakwazi ukunikela ngakho ukuze kwenziwe, ukuze kukhangiswe lesi sifundo. Kodwa futhi, cha, kusesekuseni kakhulu - ngoba muva nje siyekile ukuzethemba kancane futhi, empeleni, sesiqale ukusebenza kakhulu ngempendulo. Kukhona into efana nokuhlolwa kwe-beta - yilapho abantu bemenywa kubantu bangaphandle, abangaxhumene nenkampani yethu nganoma iyiphi indlela, futhi kwezinye izinto ezinhle baboniswa zonke izingxenye zesifundo, amavidiyo, umbhalo, imisebenzi esebenzayo, ukuze hlaziya ikhwalithi yezinto ezisetshenziswayo, ukufinyeleleka kokuqukethwe futhi usisize senze isifundo sibe muhle ngangokunokwenzeka.
- Futhi uma ukuphindaphinda okunjalo kudlula, izipikha, ukuhlolwa kwe-alpha ngendlela yosekelo lobuchwepheshe, ukuhlolwa kwe-beta, ukuthuthukiswa. Bese yonke into iqala kabusha - ukwesekwa kobuchwepheshe, ukuhlolwa kwe-beta, ukuthuthukiswa.
- Futhi ngesikhathi esithile, ukuqonda kufika ukuthi noma senziwe ngokuguqulwa, ngoba akunangqondo ngokuphelele ukwenza isiqiniseko sokuthi wonke umuntu uyayithanda, noma izinqumo ezinqala zenziwe. Uma ukuphawula okuningi ezindaweni ezithile kubucayi, kwenze kabusha emhlabeni wonke, ngoba kukhona okungahambanga kahle.
- Bese kufika isikhathi sokuhlela okuncane - endaweni ethile umusho ungakhiwanga kahle kakhulu, endaweni ethile othile angayithandi ifonti, 14,5, kodwa angathanda u-15,7.
- Uma lolu hlobo lwamazwana luhlala, yilapho-ke, inkambo ivuleka kancane, ukuthengiswa okusemthethweni kuyaqala.
Futhi ekuboneni kuqala, umsebenzi omfushane futhi olula wokwenza isifundo uphenduka ungelula neze futhi uthatha isikhathi eside kakhulu.
Futhi kukhona elinye iphuzu elibalulekile ukuthi ukusebenza nesifundo akupheli lapho isifundo sikhishwa. Okokuqala, sifunda ngokucophelela ukuphawula okushiywe ezingxenyeni ezithile. Futhi naphezu kwayo yonke imizamo esiyenzile, amanye amaphutha asabonwa, amanye amaphutha ayalungiswa futhi athuthukiswe endleleni, ngesikhathi sangempela, ukuze umsebenzisi ngamunye olandelayo athole isevisi engcono.
Inkambo ngayinye inomnikazi wayo womkhiqizo, okuthi, ngaphezu kokuchaza umqondo ojwayelekile, ahlole izikhathi zokugcina, abhale emaphethelweni ukuthi lapho kufika isikhathi sokubhala kabusha ngokuphelele isifundo, futhi kuzofika nakanjani, ngoba eminyakeni emibili, noma ngisho nangemva konyaka, okunye esikushoyo kuyobe kungasasebenzi ngenxa nje yokuthi kuyobe kungasekho ngokokuziphatha. Umnikazi womkhiqizo wenza amanothi emaphethelweni abantu abavame ukubuza ukuthi yimaphi amaphuzu ayengacacile, yimiphi imisebenzi ebonakala inzima kakhulu, futhi okwakubonakala sengathi, ngokuphambene nalokho, ilula kakhulu. Futhi konke lokhu kuyacatshangelwa lapho kuqoshwa kabusha inkambo, phakathi nohlobo oluthile lokuphindaphinda, ukuze ukuphindaphinda ngakunye kwesifundo somhlaba wonke kube ngcono, kube lula futhi kukhululeke.
Zivela kanje izifundo.
Isifundo se-Docker sazalwa kanjani
Lesi isihloko esihlukile futhi esingajwayelekile kithi. Ngoba ngakolunye uhlangothi, asihlelanga ukukwenza, ngoba izikole eziningi eziku-inthanethi ziyakunikeza. Ngakolunye uhlangothi, ucele ukukhululwa futhi wathola indawo enengqondo kumqondo wethu wokuqeqesha ochwepheshe be-IT e-Kubernetes.
Ngikhuluma emhlabeni wonke, ekuqaleni konke kwaqala ngesifundo ku-Kubernetes, lapho isanda kuqala, ngokubona kwami, ngemva kwe-Slurm yokuqala. Siqoqe impendulo futhi sabona ukuthi abantu abaningi bafuna ukufunda okuthile okwengeziwe nge-Docker kwenye indawo, futhi ngokuvamile abaningi beza esifundweni esiyisisekelo se-Kubernetes bengazi ukuthi siyini. .
Ngakho-ke, okwesibili i-Slurm benza isifundo - noma kunalokho, hhayi ngisho nesifundo, kodwa benza izahluko ezimbalwa ku-Dockers. Lapho babetshela khona ezinye zezinto eziyisisekelo, ukuze abantu abeza e-intensive bangazizwa bencishwa futhi bazoqonda ngokujwayelekile ukuthi kwenzekani.
Futhi-ke izenzakalo zathuthuka cishe kanje. Inani lempahla lakhula futhi layeka ukufaneleka ezinsukwini ezi-3. Futhi kwavela umqondo ophusile nosobala: kungani singaguquleli esikufunda e-Slurm Basic kube uhlobo oluthile lwesifundo esincane ongathumela kuso abantu abafuna ukubuka okuthile nge-Docker ngaphambi kokuthatha izifundo ezijulile ku-Kubernetes.
I-Slurm Junior, empeleni, iyinhlanganisela yezifundo ezimbalwa ezinjalo eziyisisekelo. Ngenxa yalokho, izifundo ze-Docker zaba ucezu lwe-Slurm Junior. Okusho ukuthi, lesi yisinyathelo esinjalo se-zero ngaphambili и . Futhi-ke kwakukhona nje izifinyezo eziyisisekelo kakhulu.
Ngesinye isikhathi, abantu baqala ukubuza: “Bafo, konke lokhu kuhle, lokhu kwanele ukuqonda ukuthi ukhuluma ngani ezifundweni ezijulile. Ngingayifunda kuphi imininingwane eyengeziwe mayelana nokuthi i-docker ingayenza kanjani nokuthi isebenza kanjani ngayo, nokuthi iyini? ” Ngakho kwavela umqondo wokuwenza aqonde , ukuze, okokuqala, abantu abeza ku-Slurm besebenzisa i-Kubernetes basengakwazi ukuthunyelwa kuyo, futhi ngakolunye uhlangothi, kulabo abangenasithakazelo ku-Kubernetes kulesi sigaba sokuthuthukiswa. Ukuze uchwepheshe we-IT eze azobuka isifundo sethu ku-Docker futhi aqale indlela yakhe yokuziphendukela kwemvelo kalula nje nge-Docker emsulwa. Ukuze sibe nesifundo esigcwele esiphelele, esiphelele - bese abaningi, sebebukele lesi sifundo, sebesebenze isikhathi esithile ne-Docker ehlanzekile, bakhule baze bafika ezingeni lapho bedinga khona i-Kubernetes noma olunye uhlelo lwe-orchestration. Futhi beza kithi ngokukhethekile.
Kwesinye isikhathi umbuzo uyabuzwa: "Hlobo luni lwabantu manje olungadingi uKubernetes?" Kodwa lo mbuzo awuphathelene nabantu, kunalokho umbuzo mayelana nezinkampani. Lapha udinga ukuqonda ukuthi i-Kubernetes inezimo ezithile lapho ifaneleka khona kanye nemisebenzi eyixazulula kahle, kodwa ngokuphambene nalokho, kunezinye izimo zokusebenzisa i-Kubernetes lapho kubangela ubuhlungu obengeziwe nokuhlupheka okwengeziwe. Ngakho-ke, akuncikile ngisho nakubantu, kodwa ukuthi yiziphi izinkampani ezithuthukile nokuthi isikhathi eside kangakanani.
Isibonelo, enye i-Legacy monolith embi - cishe akufanele uyiphushele ku-Kubernetes, ngoba izodala izinkinga eziningi kunezinzuzo. Noma, isibonelo, uma lokhu kuyiphrojekthi encane, inomthwalo omncane noma, ngokuyisisekelo, hhayi imali eningi nezinsiza. Asikho isidingo sokuyihudulela ku-Kubernetes.
Futhi ngokuvamile, cishe, ngokuvamile, njengoba abantu abaningi sebeshilo, uma ubuza umbuzo: "Ingabe ngidinga i-Kubernetes?", Khona-ke cishe awudingi. Angikhumbuli ukuthi ubani owafika kuqala, ngombono wami, uPasha Selivanov. Ngiyavumelana nalokhu ngo-100%. Futhi udinga ukukhula ku-Kubernetes - futhi lapho sekuvele kucace ukuthi ngidinga i-Kubernetes futhi inkampani yethu iyayidinga, futhi izosiza ukuxazulula izinkinga ezinjalo nezinjalo, khona-ke mhlawumbe kunengqondo ukuhamba ufunde futhi uthole ukuthi ukusetha kanjani it up kahle, ukuze inqubo yokushintshela ku-Kubernetes ingabi buhlungu kakhulu.
Ezinye izifo zezingane kanye nezinye izinto ezilula, ngisho nezingezilula kakhulu, zingatholakala ikakhulukazi kithi, futhi ungadlulisi eyakho ireki nobuhlungu.
Izinkampani eziningi zihambe ngendlela yokuthi ekuqaleni bekunohlobo oluthile lwengqalasizinda ngaphandle kokufakwa kwamabhokisi. Baze bafika lapho kwaba nzima khona ukuphatha konke, bashintshela kwaDocker nokuthe ngokuhamba kwesikhathi bakhula baze bacinana ngaphakathi kohlaka lweDocker nalokho elikunikezayo. Futhi baqala ukubheka ukuthi yini eseduze, yiziphi izinhlelo ezixazulula lezi zinkinga, futhi ikakhulukazi i-Kubernetes - lena ingenye yalezo zinhlelo ezikuvumela ukuthi uxazulule izinkinga lapho i-Docker ehlanzekile iba minyene futhi ingasebenzi, leli yicala elihle ngempela lapho abantu. Bahamba ngesinyathelo ngesinyathelo ukusuka phansi phezulu, baqonde ukuthi lobu buchwepheshe abanele futhi baqhubekele ezingeni elilandelayo. Basebenzisa okuthize, kwaphinde kwaba yindlala, baqhubekela phambili.
Lesi yisinqumo esihlakaniphile - futhi kuhle kakhulu.
Ngokuvamile, ngibona ukuthi uhlelo lwethu lwakhiwe kahle kakhulu, isibonelo, , ngisho nangezifundo zevidiyo. Ngemuva kwalokho i-docker iyahamba , Khona-ke , Khona-ke . Yonke into ilandelana ngokunengqondo - umuntu uyaphasa bese kuvela umkhakha oqinile.
Eqinisweni, isethi yezifundo ikuvumela ukuthi uhlanganise amacala amaningi, ngisho nesimanjemanje. Kusenezindawo ezisasele ezimpunga, ngiyethemba ukuthi maduze sizodala izifundo ezizosivumela ukuthi sivale lezi zindawo ezimpunga, ikakhulukazi, sizoqhamuka nento ethinta ezokuphepha. Ngoba lokhu kuya ngokuya kuhambisana kakhulu.
Ngamafuphi, sinezindawo ezimpunga okungaba kuhle kakhulu ukuzivala, ukuze kube isithombe esiphelele, esiphelele - futhi abantu bangeza, futhi njengoKubernetes uqobo lwakhe lufana nomakhi we-Lego, ungenza izinto ezahlukene kusuka. iqoqa, uma kusekhona okwanele - ukungezelela, okufanayo nezifundo zethu, ukuze abantu baqonde ukuthi yini abayidingayo kulokhu; badinga ukuhlanganisa uhlobo lwephazili, uhlobo lokwakha olusethwe ezifundweni zethu.
Uma uzibuza umbuzo ojwayelekile nothembekile: "Ubani ongasebenzisa isifundo se-Docker esisebenzayo manje?", bese:
- Okwabafundi abasaqala ukungena kuyona.
- Ukuhlola abasebenzi bomnyango.
- Eqinisweni, kunezinkampani eziningi ezisalokhu zingasebenzisi i-Docker kuphela, kodwa akekho oke wezwa ngobuchwepheshe obunjalo futhi, empeleni, abazi ukuthi busetshenziswa kanjani. Futhi ngiyazi izinkampani ezinkulu eziningana eSt. Petersburg eziye zathuthuka iminyaka eminingi, futhi zasebenzisa ubuchwepheshe obudala, zihamba ngale ndlela. Ikakhulukazi, ezinkampanini ezinjalo, konjiniyela ezinkampanini ezinjalo, le nkambo ingaba mnandi kakhulu, ngoba, okokuqala, izokuvumela ukuthi ucwiliswe ngokushesha kulobu buchwepheshe, futhi okwesibili, ngokushesha nje lapho kuvela onjiniyela abaningana abaqonda ukuthi konke kwenzeka kanjani. isebenza, bangayiletha enkampanini futhi bathuthukise lesi siko kanye nalezi zikhombisi-ndlela ngaphakathi kwenkampani.
- Ngokubona kwami, lesi sifundo singase sibe usizo kulabo asebevele basebenza nge-docker, kodwa kuncane kakhulu nangaphezulu ngesitayela esithi "yenza kanye, yenza kabili" - futhi manje bazosebenzisana ngandlela thize ne-Kubernetes efanayo, futhi lokhu ibeka izibopho ezithile kubo, uma unolwazi olukha phezulu kakhulu lokuthi i-docker iyini, ukuthi iqhutshwa kanjani, kodwa ngesikhathi esifanayo awazi ukuthi isebenza kanjani ngaphakathi, awazi ukuthi yini engcono kakhulu ongayenza ngayo. yona kanye nalokho okungcono ukungakwenzi, Khona-ke lesi sifundo sifaneleka kahle ukuhlela nokujulisa ulwazi.
Kepha uma unolwazi ezingeni lokuthi: "Angazi ukuthi ngingabhala kanjani amafayela e-Docker afanayo ngendlela efanele, ngingacabanga ukuthi ziyini izikhala zamagama, ukuthi iziqukathi zisebenza kanjani, ukuthi empeleni zenziwa kanjani ezingeni lesistimu yokusebenza" - khona-ke kukhona nakanjani asikho isidingo sokuya kithi, ngeke ufunde lutho olusha futhi uzodabukisa kancane ngemali nesikhathi esichithiwe.
Uma sakha ukuthi yiziphi izinzuzo inkambo yethu enazo, khona-ke:
- Sizamile ukwenza lesi sifundo ngenani elanele lamacala asebenzayo azokuvumela ukuthi ungagcini nje ngokuqonda ingxenye yethiyori ekhona, kodwa futhi uqonde ukuthi kungani uyidinga nokuthi uzoyisebenzisa kanjani esikhathini esizayo;
- kunezigaba ezimbalwa ezingavamile ukutholakala noma kuphi - futhi ngokuvamile azikho izinto eziningi kangako kuzo. Zihlobene nokusebenzelana kwe-Docker nohlelo lokusebenza, ngisho nokuhlukile kancane. Yiziphi izindlela u-Docker azithatha ohlelweni lokusebenza ukuze asebenzise uhlelo lokuthwala - futhi lokhu kunikeza ukuqonda okujulile ngodaba lonke lokusebenzisa iziqukathi ngaphakathi kwesistimu yokusebenza ye-Linux. Isebenza kanjani, isebenzisana kanjani phakathi kwesistimu yokusebenza, ngaphandle, njalonjalo.
Lokhu kubukeka okujule ngempela kangangokuthi kwenzeka kuyaqabukela, futhi ngesikhathi esifanayo, ngokubona kwami, kubaluleke kakhulu. Uma ufuna ukuqonda noma yibuphi ubuchwepheshe kahle futhi uqonde ukuthi yini ongayilindela kubo, udinga okungenani ube nombono ojwayelekile wokuthi busebenza kanjani ezingeni eliphansi.
Isifundo sethu sibonisa futhi sisho ukuthi lokhu kusebenza kanjani ngokubuka kwesistimu yokusebenza. Ngakolunye uhlangothi, wonke amasistimu wokuqukatha asebenzisa izindlela zesistimu yokusebenza efanayo. Ngakolunye uhlangothi, bathatha okukuhlelo lokusebenza lwe-Linux, njenge-docker. Amanye amasistimu okufaka iziqukathi awazange aqhamuke nanoma yini entsha - athathe lokho osekuvele ku-Linux futhi abhala isembozo esilula esikuvumela ukuthi uyibize ngokushesha, uyiqhube, noma uhlanganyele nayo ngandlela thize. I-Docker efanayo ayiyona isendlalelo esikhulu kakhulu phakathi kwesistimu yokusebenza nomugqa womyalo, iwuhlobo lwensiza evumela ukuthi ungabhali ama-kiloton wemiyalo noma uhlobo oluthile lwekhodi C ukuze udale isitsha, kodwa ukwenza lokhu ngokufaka imigqa embalwa kutheminali.
Futhi enye into, uma sikhuluma ngokuqondile nge-Docker, lokho u-Docker akulethe ngempela emhlabeni we-IT ngamazinga. Indlela uhlelo lokusebenza okufanele luqaliswe ngayo, ukuthi kufanele lusebenze kanjani, yiziphi izidingo zamalogi, yiziphi izidingo zokukala, ukumisa uhlelo lokusebenza ngokwalo.
Ngezindlela eziningi, i-docker imayelana namazinga.
Amazinga nawo aya ku-Kubernetes - futhi kukhona amazinga afanayo ncamashi; uma wazi ukuthi ungalusebenzisa kanjani uhlelo lwakho lokusebenza kahle ku-Docker, khona-ke u-99% wesikhathi uzosebenza kahle ngaphakathi kwe-Kubernetes.
Uma uzithole unentshisekelo hhayi kuphela ekutheni isifundo se-Docker sakhiwe kanjani, kodwa futhi nakwezinye izifundo, kodwa futhi unesithakazelo esifundweni ngokwaso ngokombono ongokoqobo, khona-ke
Sizojabula ukukubona!
