Chifukwa Kubespray?
Tidakumana ndi Kubernetes zaka zopitilira ziwiri zapitazo - izi zisanachitike tidakhala ndi chidziwitso chogwira ntchito ndi Apache Mesos ndipo tidasiya gulu lambiri la docker. Choncho, chitukuko cha k8s nthawi yomweyo chinatsatira dongosolo la Brazil. Palibe ma minicubes kapena njira zowongolera kuchokera ku Google.
Kubeadm panthawiyo samadziwa kusonkhanitsa gulu la etcd, ndipo mwazosankha zina, kubespray anali pazotsatira zapamwamba za Google.
Tinaziyang'ana ndipo tinazindikira kuti tiyenera kuzitenga.
Pa September 23, 20.00 nthawi ya Moscow, Sergey Bondarev adzachititsa , komwe angakuuzeni momwe mungakonzekere kubespray kuti ikhale yokoma, yogwira mtima komanso yololera zolakwika, ndiyeno lingaliro lakuti "si ma yogurt onse omwe ali ndi thanzi labwino" silimatuluka.
Pa webinar, Sergey Bondarev akuwuzani momwe kubespray imagwirira ntchito, pali kusiyana kotani ndi kubeadm, kops, rke. Adzagawana mawonekedwe apadera a kubespray ndi cluster install algorithm. Adzasanthula mbali (zoyipa) za ntchito zamafakitale.
Nanga bwanji timagwira kubespray ndi manja onse atatu?
- Ndi zomveka komanso opensource. Mutha kuwonjezera mphindi zanu nokha.
- Mutha kuyiyika pa Centos, komanso pamagawidwe ena π
- Kupanga kwa HA. Zololera zolakwika etcd gulu la 3 masters.
- Kutha kuwonjezera ma node ndikusintha masango.
- Kuyika kwa mapulogalamu owonjezera monga dashboard, seva ya metrics, ingress controller, etc.
Script imagwiranso ntchito ndi mitogen. Zomwe zimapereka mathamangitsidwe a 10-15%, palibenso, chifukwa nthawi zambiri amatsitsa zithunzi ndikuyika.
Kunena zowona, pakadali pano kusankha kwa kubespray kukhazikitsa masango sikukuwonekeratu monga momwe zidalili zaka ziwiri zapitazo.
Mwachidule...
Mwachitsanzo, kops - ngati cubespray, imakulolani kuti muyike masango kuyambira pachiyambi, ngakhale kupanga makina enieni. Koma AWS, GCE ndi ntchito yotseguka. Ndi mtundu uti womwe umadzutsa funso - chifukwa chiyani kuli kofunikira ngati mitambo iyi ili ndi mayankho owongolera, ngakhale pagulu lotseguka, mwachitsanzo selectel kapena mail.ru. rke - anthu ena amawakonda, koma ali ndi njira yawoyawo pamapangidwe a masango omwe amapangidwa ndipo alibe mwayi waukulu wopanga magawo amagulu. Kuphatikiza apo, mufunika node yokhazikitsidwa kale yokhala ndi docker yoyikidwa. kubeadm - imafunanso Docker, chida chochokera kwa opanga Kubernetes, chomwe chaphunziranso kupanga zokhazikika zololera zolakwika, kusunga zosintha ndi satifiketi mkati mwa tsango, ndipo tsopano palibe chifukwa chosinthira pamanja mafayilowa pakati pa node. Chida chabwino, koma chongoyang'ana pakukweza chigwa chowongolera. Simayikiranso netiweki mgululi, ndipo zolembedwazo zikuwonetsa kugwiritsa ntchito mawonekedwe ndi CNI pamanja.
Chabwino, chowonadi chofunikira ndichakuti zonse zitatuzi zidalembedwa popita, ndipo ngati mukufuna china chapadera, muyenera kudziwa pitani kuti mukonze khodi ndikupanga pempho kukoka.
Cubspray ndi chinthu chosavuta kuphunzira kuposa kupita.
Chabwino, ndipo, pogwiritsa ntchito zomwezo, mutha kulemba zolemba zanu pakuyika docker ndi gulu pogwiritsa ntchito rke kapena kubeadm. Ndipo zolembedwa izi, chifukwa chaukadaulo wawo wopapatiza makamaka pazofuna zanu, zigwira ntchito mwachangu kuposa ma cubespray. Ndipo iyi ndi njira yabwino kwambiri, yogwira ntchito. Ngati muli ndi luso komanso nthawi.
Ndipo ngati mutangoyamba kumene kudziwana , ndiye kudziwa cubespray kudzakhala kosavuta komanso mwachangu.
Ndipo ndi gawo chabe la zomwe tikambirana. Sizidzakhala zotopetsa. Bwerani ndi . Kapena kulembetsa ndi . Chilichonse chomwe mungafune.
