Kungani Kubespray?
Sahlangana no-Kubernetes eminyakeni engaphezudlwana kwemibili edlule - ngaphambi kwalokho saba nesipiliyoni sokusebenza ne-Apache Mesos futhi sashiya ngempumelelo iqulu le-docker. Ngakho-ke, ukuthuthukiswa kwama-k8s kwalandela ngokushesha uhlelo lwaseBrazil. Awekho ama-minicubes noma izixazululo zokuphatha ezivela ku-Google.
U-Kubeadm ngaleso sikhathi wayengazi ukuthi alihlanganisa kanjani iqoqo njlld, kanti kwezinye izinketho, i-kubespray yayisemiphumeleni ephezulu ye-Google.
Sayibuka sabona ukuthi kufanele siyithathe.
Ngo-September 23, 20.00 Isikhathi saseMoscow, u-Sergey Bondarev uzoqhuba , lapho ezokutshela khona ukuthi ungayilungisa kanjani i-bespray ukuze ibe mnandi, iphumelele futhi ibekezelele amaphutha, bese umcabango othi "akuwona wonke ama-yoghurt anempilo ngokulinganayo" awuveli.
Ku-webinar, u-Sergey Bondarev uzokutshela ukuthi i-kubespray isebenza kanjani, uyini umehluko ku-kubeadm, kops, rke. Izokwabelana ngezici ezihlukile ze-kubespray kanye ne-algorithm yokufaka iqoqo. Izohlaziya izici (ibubi) yokusebenza kwezimboni.
Pho kungani sibamba i-kubespray ngazo zontathu izandla?
- Iyaqondakala futhi ingumthombo ovulekile. Ungakwazi ukuzingezela izikhathi ezithile.
- Ungayifaka ku-Centos, nakwamanye ama-distributions 😉
- Ukusetha kwe-HA. Iqoqo elibekezelela amaphutha etcd lamakhosi angu-3.
- Ikhono lokwengeza ama-node nokuvuselela iqoqo.
- Ukufakwa kwesofthiwe eyengeziwe efana nedeshibhodi, iseva yamamethrikhi, isilawuli sokungena, njll.
Iskripthi esisebenzayo siphinde sisebenze ne-mitogen. Okunikeza ukusheshisa kwe-10-15%, akusekho, ngoba isikhathi esiningi sichithwa ukulanda izithombe nokufakwa.
Uma sikhuluma ngokunenhloso, okwamanje ukukhetha kwe-kubespray yokufaka iqoqo akucishe kucace njengoba kwakunjalo eminyakeni emibili edlule.
Kafushane...
Isibonelo, i-kops - njenge-cubespray, ikuvumela ukuthi ufake iqoqo kusukela ekuqaleni, uze udale imishini ebonakalayo ngokwakho. Kodwa kuphela i-AWS, i-GCE nomsebenzi ovulekile. Iluphi uhlobo oluphakamisa umbuzo - kungani ludingeka uma lawa mafu enezixazululo zokuphatha, ngisho naku-stack evulekile, isibonelo i-selectel noma i-mail.ru. I-rke - abanye abantu bayayithanda, kodwa banendlela yabo yokwakheka kweqoqo elidalwayo futhi abanawo amathuba amahle kakhulu okwenza ngokwezifiso izingxenye zeqoqo. Futhi, udinga i-node esivele imisiwe ene-docker efakiwe. kubeadm - futhi idinga i-Docker, insiza evela kubathuthukisi be-Kubernetes, ekugcineni efunde ukuthi ungakha kanjani ukusetha okubekezelela amaphutha, ugcine ukulungiselelwa nesitifiketi ngaphakathi kweqoqo, futhi manje asikho isidingo sokudlulisa lawa mafayela ngesandla phakathi kwama-node. Ithuluzi elihle, kodwa eligxile kuphela ekukhuliseni ithafa lokulawula. Ayifaki ngisho inethiwekhi kuqoqo, futhi imibhalo iphakamisa ukusebenzisa i-manifest nge-CNI ngesandla.
Nokho, iqiniso elibalulekile ukuthi zonke lezi zinsiza ezintathu zibhalwa ekuhambeni, futhi uma udinga okuthile okuhlukile, udinga ukwazi hamba ukuze ulungise ikhodi futhi udale isicelo sokudonsa.
I-Cubspray iyi-ansible okulula ukuyifunda kunokuhamba.
Yebo, futhi-ke, usebenzisa i-ansible efanayo, ungabhala izikripthi zakho zokufaka i-docker kanye neqoqo usebenzisa i-rke noma i-kubeadm. Futhi le mibhalo, ngenxa yobungcweti bayo obuncane obuqondene ngqo nezidingo zakho, izosebenza ngokushesha kakhulu kune-cubespray. Futhi lokhu kuyindlela enhle kakhulu, esebenzayo. Uma unekhono nesikhathi.
Futhi uma usaqala ukujwayelana , khona-ke ukuphatha ama-cubespray kuzoba lula kakhulu futhi ngokushesha.
Futhi lokho kuyingxenye nje yalokho esizokhuluma ngakho. Ngeke kube yisicefe. Woza futhi . Noma bhalisa futhi . Noma yini oyikhethayo.
