I-Turing Pi iyisixazululo sezinhlelo zokusebenza ezizibambele ngokwazo ezakhelwe kumgomo wama-rack racks esikhungweni sedatha, kuphela ebhodini lomama elihlangene. Isixazululo sigxile ekwakheni ingqalasizinda yendawo ukuze kuthuthukiswe indawo kanye nokusingathwa kwezicelo namasevisi. Ngokuvamile, kufana ne-AWS EC2 yonqenqema kuphela.
Thina, ithimba elincane labathuthukisi, sinqume ukudala isixazululo sokwakha amaqoqo ensimbi engenalutho emaphethelweni futhi sabiza iphrojekthi i-Turing Pi. Umkhiqizo waqala njengephrojekthi yokuqala, kodwa manje, ukuhlola imiqondo yabo, uyalwe yiminyango yezokuthuthukiswa kwaRed Hat, Rancher (SUSE), Toyota Connected, Sony, Electrolux, Facebook, kanye nezithameli zabathuthukisi abangaphansi kuka-10K. ukubuthwa.
Kodwa konke kwaqala ngokutholakala.
Ukutholwa komkhiqizo
Ngesinye isikhathi ngathola ukuthi asiqambi lutho. Sithola zonke izinto ezikhona kulo mhlaba. Sithola ukuthi ezinye izingxenye zingahlanganiswa ndawonye, ββzithole izakhiwo ezintsha zemikhiqizo, noma sithole imithetho bese siyihlanganisa futhi. Awukwazi ukuqhamuka nanoma yini, kodwa ungayithola ngesikhathi socwaningo. Ngokubona kwami, okusunguliwe kuwumphumela wokubhekwa njalo, ukuhlola nokusesha + inhlanganisela yolwazi.
Kule minyaka eyishumi edlule, ngibuke umnyakazo we-homelab wabafundi uzuza umfutho (insiza ), ukuzisingatha ngokwakho (izinsiza ΠΈ ), amakhompiyutha ebhodi elilodwa, njengoba isithakazelo ekusebenziseni iziqukathi kumakhompiyutha ebhodi elilodwa njenge-Raspberry Pi ikhula, kukhona ukunyakaza okukhulayo kokuhlanganisa amaqoqo amakhompiyutha ebhodi elilodwa. Umqondo weKubernetes uhamba kancane kancane lapho. Inguqulo yayo engasindi, i-k3s, egxile ku-Edge/IoT, isivele yavela. Itsheyini elikhulu lokudla okusheshayo I-Chick-fil-A ingelinye lokuqala emhlabeni ukuthumela amaqoqo e-Kubernetes emakhishini ayo .
Ngiyibona njengebhola leqhwa, njengoba ubuchwepheshe obunye bugoqa obunye, budala uhlelo oluyinkimbinkimbi. Ngesikhathi esifanayo, azikho izinxushunxushu, ezifana ne-fractal evela kubuchwepheshe. Kwesinye sezikhathi ezinzima kakhulu empilweni yami kimi, ngabona ukubaluleka kumaqoqo ahlanganiswa kusuka kumakhompiyutha ebhodi elilodwa ngabathuthukisi abayizimfundamakhwela futhi ngaqala ukusebenza ekwakheni ibhodi leqoqo.
Namuhla ibhodi yethu yeqoqo ilula kakhulu futhi ngokuyinhloko ihloselwe labo abathanda ubuchwepheshe bomdabu basefu, bafunde izinto ezintsha, futhi bahlole.
Amabhulokhi Okwakha
Ngakho-ke, siyini isixazululo, siyini ingqikithi. Iphuzu liwukunikeza umakhi, amabhlogo wokwakha (Izibhulokhi Zokwakha) lapho ungahlanganisa khona ingqalasizinda enqenqemeni eshibhile kunamaseva akudala, amabhokisi ensimbi ahambayo angenawo amakhulu, angadingi izimo zokusebenza ezikhethekile ezifana namakamelo amaseva, ukonga amandla, amisiwe ngokwemibandela. yamamojula kanye nekhono lokukala ngokushesha emashumini namakhulu amanodi ekhompiyutha (amaprosesa).
I-Clusterboard
Ibhodi elincane le-ITX lixhuma amamojula amaningi ekhompiyutha lisebenzisa inethiwekhi esebhodini, linikeza ukuxhumana kwe-peripheral nokulawula amamojula.

Ibhodi ku-SO-DIMM form factor equkethe iphrosesa ne-RAM, inkumbulo ekhanyayo yokuzikhethela yokugcina isistimu yokusebenza
Okunye kokucushwa okuhlosiwe kwe-Turing V2
Ngokuhlanganisa ibhodi le-cluster kanye namamojula e-computing, kulula ukudala ingqalasizinda, isibonelo, ama-processor angu-20+ (izibonelo ezingezansi), athule futhi asebenzisa amandla aphansi. Ibhodi le-cluster ngokwayo likhulisa ukusebenza kahle kwevolumu esetshenzisiwe. Izibonelo zamaqoqo ukuze kuqhathaniswe

Ukuze sithole ubufakazi bomqondo, sikhethe i-Raspberry Pi Compute Module - lokhu ukucushwa okufanele ukuqala ngakho. Umphakathi we-RPi uyasebenza, azikho izinkinga ngesofthiwe, imojula ngokwayo ifomethi ye-SO-DIMM (6 x 3 cm), iyathengeka, iqukethe i-CPU engu-4-core, i-RAM engu-1 GB kanye nememori ye-flash oyikhethayo. 8, 16 noma 32 GB ye-OS nezinye izidingo zesistimu. Lesi sici sefomu sivame ukusetshenziswa kuzixazululo ze-IoT yezimboni.
I-Raspberry Pi 1/3/3+ Compute Module
Kepha imodeli ye-CM3 nayo inokulinganiselwa okukhulu - max. 1 GB RAM ne-Ethernet nge-USB HUB enesivinini esiphezulu esingafika ku-100 Mbps. Ngakho-ke, inguqulo yesibili ye-Turing izosekela i-Raspberry Pi 4 futhi ifike ku-8 GB ye-RAM module ngayinye. Ngezansi kunesibonelo samamojula we-Nvidia Jetson wemisebenzi ye-Accelerated Computing. Mhlawumbe bazosekelwa enguqulweni yesibili, uma sixazulula izinkinga ezithile zobuchwepheshe, khona-ke singakwazi ukuxuba amamojula.
I-Nvidia Jetson Compute Modules
Amamojula aqukethe isici esibaluleke kakhulu, esingabonakali ekuqaleni. Ikhono lokudala amanye amamojula ngendlela efanayo enesethi ehlukile ye-CPU, i-RAM ne-eMMC, ezinhlotsheni ezihlukene zemisebenzi kusukela kukhompyutha evamile ukuya kukhompyutha yokufunda ngomshini. Lokhu kufana kakhulu nezimo ze-AWS EC2, kodwa okonqenqema kuphela. Kulokhu, ibhodi leqoqo lihlala lingashintshiwe noma linezinguquko ezincane.
I-Clusterboard
Ingase futhi ibizwe ngokuthi ibhodi lomama noma ibhodi lesisekelo, isiqondiso esisha futhi namuhla abekho abakhiqizi abaningi bezixazululo ezinjalo futhi basesezingeni lokungena, phakathi kwabo i-Pine64, i-MiniNodes, i-Clover Pi, i-Bitscope Blade, i-PicoCluster (amaqoqo e-SBC ). Ibhodi le-cluster lixhuma amamojula nenethiwekhi, linikeza amandla futhi linikeze ibhasi lokuphatha iqoqo (Cluster Management Bus), okungenani sinqume ukwengeza leli bhasi futhi kubonakala sengathi seliqalile.

I-Bandplane Bandwidth 12 Gbps
Izikhala ze-SD zamamojula ngaphandle kwe-EMMC, isibonelo, ungagcina amamojula ambalwa nge-SD ukuze uthole ukufinyelela okusheshayo kudatha ye-node
Ibhodi leqoqo lisekelwe ku-switch chip ukuze kuqinisekiswe ukuxhumeka kwenethiwekhi kwamamojula kanye nokufinyelela kunethiwekhi yangaphandle. Enguqulweni yamanje sisebenzisa iswishi engaphethwe ngoba Sasingekho isikhathi sokuqhuba i-R&D egcwele, kodwa enguqulweni yesibili sakhetha ukushintshwa okuphethwe kahle. Kungenzeka ukuyimisa kumodi 'ye-master node njenge-router' ukuze kusatshalaliswe inethiwekhi ebhodini; lokhu kwenzeka uma izinga eliphezulu lokuvikeleka kanye nokuhlukaniswa kwabasebenzi ngaphandle kokufinyelela ngaphandle kuyadingeka, lapho futhi kuyadingeka ukugcina. iseva ye-DHCP ku-master node.
Isicelo
Inguqulo yamanje ingeyokuhlola futhi siyibeka njengesixazululo sezinga lokungena ukuze sifunde ukuthi amaqoqo ayini, sisebenze nesofthiwe, noma njengokuhlola okucatshangwayo ezinhlanganweni, sifuna imibono emisha, ngokuvamile, lena inguqulo ye-Lite.
Ukuze uqalise, sincoma uchungechunge oluvela kuJeff Girling omangalisayo, ofunde ngathi kwa-Y Combinator futhi ongumbhali wencwadi edayise kakhulu Ansible for DevOps. Waphefumulelwa kangangokuthi wenza ukubuyekezwa okuyizingxenye eziyisi-6, eqala emcabangweni wokuhlanganisa ngokujwayelekile kuya ezibonelweni ezisebenzayo zokusebenza nebhodi, ukufunda iKubernetes nokuthi iyiphi isoftware engafakwa.
Uchungechunge olumayelana nokufaka ama-k3 kuqoqo
Ngokuvamile, ngincoma ukubuka kusukela kweyokuqala, lapho ngokujwayelekile mayelana nokuhlanganisa kanye ne-Kubernetes ngolimi olufinyelelekayo. Nezinye izithombe ezivela emphakathini
Yini okulandelayo?
Okokuqala, ngethemba ngempela ukuthi bekuthakazelisa. Lokhu okuqukethwe kwangempela, umzamo wokubheka ngale komkhathizwe. Okwesibili, ngihlela ukubhala ingxenye yesibili mayelana nomklamo weTuring V2. Ukucinga komkhiqizo kwenzeke kanjani, izahlulelo ezinengqondo, ukusesha kwezakhiwo ezibalulekile ezibalulekile. I-athikili izoqukatha imidwebo yomkhiqizo kusukela kweyokuqala kuya kweyokugcina. Isihloko sesibili sizoba nesithakazelo esikhethekile kososayensi bomkhiqizo, abanomthwalo wemfanelo wemikhiqizo nokuthuthukiswa kwayo ezinkampanini.
Futhi cishe kuyoba khona ukufunda isikhathi eside ngempela.
