Ne jemi t\u00eb lumtur t\u00eb ndajm\u00eb lajmin se Contour \u00ebsht\u00eb vendosur n\u00eb inkubatorin e projekteve nga Cloud Native Computing Foundation (CNCF). <\/p>\n

<\/p>\n

N\u00ebse nuk keni d\u00ebgjuar ende p\u00ebr Contour - ky \u00ebsht\u00eb nj\u00eb controller i thjesht\u00eb dhe t\u00eb shkall\u00ebzuesh\u00ebm p\u00ebr ingress me kod t\u00eb hapur p\u00ebr ruterimin e trafikut n\u00eb aplikacionet e nisura n\u00eb Kubernetes. <\/p>\n

<\/p>\n

Ne do t\u00eb shqyrtojm\u00eb me detaje se si funksionon, do t\u00eb tregojm\u00eb nj\u00eb \"hart\u00eb rrugore\" t\u00eb zhvillimit n\u00eb konferencat e ardhshme Kubecon dhe CloudNativeCon Europe<\/a><\/noindex>. <\/p>\n

<\/p>\n

N\u00eb k\u00ebt\u00eb artikull, ju ftojm\u00eb t\u00eb njiheni me funksionimin e Contour. Do t\u00eb shpjegojm\u00eb \u00e7far\u00eb do t\u00eb thot\u00eb pranim projekti n\u00eb CNCF. Gjithashtu, do t\u00eb ndajm\u00eb planet p\u00ebr zhvillimin e ardhsh\u00ebm t\u00eb projektit.<\/p>\n

<\/p>\n

Konferencat KubeCon dhe CloudNativeCon mbledhin besnik\u00ebt e teknologjive t\u00eb avancuara dhe inxhinier\u00ebt e interesuar jo vet\u00ebm p\u00ebr m\u00ebsimin e m\u00ebtejm\u00eb, por edhe p\u00ebr promovimin e llogarive cloud. N\u00eb k\u00ebto ngjarje marrin pjes\u00eb ekspert\u00eb praktik\u00eb dhe zhvillues kryesor\u00eb t\u00eb projekteve t\u00eb njohura, si Kubernetes, Prometheus, gRPC, Envoy, OpenTracing dhe t\u00eb tjer\u00eb.<\/p><\/blockquote>\n

P\u00ebr fillim, nj\u00eb hyrje.

Por n\u00eb \u00e7\u00ebshtjet e krijimit t\u00eb rrjeteve dhe sigurimit t\u00eb lidhshm\u00ebris\u00eb ka ende hap\u00ebsir\u00eb p\u00ebr inovacion. Nj\u00eb nga detyrat kryesore, p\u00ebrve\u00e7 k\u00ebsaj shum\u00eb t\u00eb r\u00ebnd\u00ebsishme, \u00ebsht\u00eb d\u00ebrgimi i trafikut t\u00eb jasht\u00ebm brenda klasterit. N\u00eb Kubernetes, kjo quhet Ingress, dhe k\u00ebtu \u00ebsht\u00eb ku Contour hyn n\u00eb loj\u00eb. Ky \u00ebsht\u00eb nj\u00eb mjet q\u00eb mund ta p\u00ebrdorni leht\u00ebsisht n\u00eb klasterin tuaj p\u00ebr t\u00eb d\u00ebrguar trafikun sipas nevoj\u00ebs, por me nj\u00eb funksionalitet t\u00eb nd\u00ebrtuar p\u00ebr t\u00eb ardhmen, nd\u00ebrsa klasteri juaj Kubernetes rritet.<\/p>\n

<\/p>\n

Teknikisht, Contour funksionon duke u p\u00ebrdorur Envoy<\/a><\/noindex> p\u00ebr t\u00eb siguruar reverse proxy dhe balancues ngarkese. Ai fillimisht mb\u00ebshtet p\u00ebrdit\u00ebsimin dinamik t\u00eb cil\u00ebsimeve dhe gjithashtu mund t\u00eb zgjerohet p\u00ebr klastere multiteam Kubernetes, duke ofruar strategji t\u00eb ndryshme balancimi ngarkese.<\/p>\n

<\/p>\n

Ka shum\u00eb alternativa p\u00ebr t\u00eb nisur Ingress Controller n\u00eb Kubernetes, por Contour \u00ebsht\u00eb unik sepse ofron vet\u00ebm k\u00ebt\u00eb detyr\u00eb, duke e b\u00ebr\u00eb at\u00eb me nj\u00eb nivel t\u00eb lart\u00eb performanc\u00ebs dhe duke e n\u00ebnvler\u00ebsuar sigurin\u00eb dhe aft\u00ebsin\u00eb e pun\u00ebs n\u00eb modin shum\u00ebp\u00ebrdorues.<\/p>\n

K\u00ebshtu propozohet nj\u00eb kalim gradual n\u00eb Ingress, gj\u00eb q\u00eb e ka interesuar shpejt shum\u00eb p\u00ebrdorues.<\/p>\n

Contour, i krijuar n\u00eb fund t\u00eb vitit 2017 nga zhvilluesit Heption, arriti versionin 1.0 n\u00eb n\u00ebntor 2019, dhe tani mund t\u00eb krenohet me nj\u00eb komunitet prej 600 pjes\u00ebtar\u00ebsh n\u00eb Slack, 300 pjes\u00ebtar\u00ebsh n\u00eb zhvillim, si dhe 90 kontributors dhe 5 mbik\u00ebqyr\u00ebs. Nj\u00eb nga faktet e r\u00ebnd\u00ebsishme \u00ebsht\u00eb se ai \u00ebsht\u00eb implementuar nga kompani dhe organizata t\u00eb ndryshme, duke p\u00ebrfshir\u00eb Adobe, Kinvolk, Kintone, PhishLabs dhe Replicated. Duke e vler\u00ebsuar se p\u00ebrdoruesit po e implementojn\u00eb Contour n\u00eb prodhim, dhe duke pasur parasysh se kemi nj\u00eb komunitet t\u00eb q\u00ebndruesh\u00ebm, CNCF vendosi q\u00eb Contour t\u00eb kaloj\u00eb menj\u00ebher\u00eb, pa kaluar n\u00eb nivelin e sandbox, n\u00eb inkubator.<\/p>\n

Ne shpresojm\u00eb se sa m\u00eb shum\u00eb njer\u00ebz t\u00eb vij\u00eb tek ne, aq m\u00eb t\u00eb larmishme dhe t\u00eb shpejta do t\u00eb jen\u00eb shtimet e funksioneve t\u00eb reja.
