Pse p\u00ebrdorim Kubernetes n\u00eb prodhim<\/h2>\n

\n\u00abLerua Merlin\u00bb \u00ebsht\u00eb lider n\u00eb tregun e DIY-retaile n\u00eb Rusi dhe Evrop\u00eb. N\u00eb kompanin\u00eb ton\u00eb ka m\u00eb shum\u00eb se nj\u00ebqind zhvillues, 33,000 punonj\u00ebs t\u00eb brendsh\u00ebm dhe nj\u00eb num\u00ebr t\u00eb madh njer\u00ebzish q\u00eb vizitojn\u00eb hipermarketet dhe faqen ton\u00eb.

T\u00eb zhvillojm\u00eb aplikacione t\u00eb reja duke p\u00ebrdorur arkitektur\u00ebn mikrosh\u00ebrbimor; p\u00ebr t\u2019i izoluar mjediset dhe p\u00ebr t\u00eb b\u00ebr\u00eb shp\u00ebrndarjen e duhur, t\u00eb p\u00ebrdorim kontejner\u00eb; dhe p\u00ebr orkestrimin t\u00eb p\u00ebrdorim Kubernetes. \u00c7mimi p\u00ebr p\u00ebrdorimin e orkestrator\u00ebve po b\u00ebhet gjithnj\u00eb e m\u00eb i lir\u00eb: n\u00eb treg po rritet numri i inxhinier\u00ebve q\u00eb zot\u00ebrojn\u00eb teknologjin\u00eb, shfaqen ofrues t\u00eb cil\u00ebt ofrojn\u00eb Kubernetes si nj\u00eb sh\u00ebrbim.<\/p>\n

Gjith\u00e7ka q\u00eb b\u00ebn Kubernetes, sigurisht, mund t\u00eb b\u00ebhet edhe me m\u00ebnyra t\u00eb tjera, p\u00ebr shembull, duke krijuar skripte me ndihm\u00ebn e ndonj\u00eb Jenkins dhe docker-compose, por p\u00ebrse duhet ta komplikoni jet\u00ebn, n\u00ebse ka nj\u00eb zgjidhje t\u00eb gatshme dhe t\u00eb besueshme? Prandaj arrit\u00ebm te Kubernetes dhe tani e p\u00ebrdorim at\u00eb n\u00eb prodhim p\u00ebr nj\u00eb vit. Aktualisht kemi nj\u00ebzet e kat\u00ebr klastera Kubernetes, m\u00eb e vjet\u00ebr se nj\u00eb vit, me rreth dyqind pod\u00eb.<\/p>\n

\nP\u00ebr t\u00eb nisur nj\u00eb mikrosh\u00ebrbim n\u00eb Kubernetes, do t\u00eb krijojm\u00eb t\u00eb pakt\u00ebn pes\u00eb skedar\u00eb YAML: p\u00ebr Deployment, Sh\u00ebrbim, Ingress, ConfigMap, Sekrete \u2014 dhe do t'i d\u00ebrgojm\u00eb n\u00eb klaster.

T\u00eb shumojm\u00eb numrin e dokumenteve me numrin e mjediseve, tashm\u00eb do t\u00eb kemi qindra skedar\u00eb, dhe kjo ende nuk p\u00ebrfshin mjediset dinamike.<\/p>\n
