Spolo\u010dnos\u0165 Google predstavila stabiln\u00fa verziu platformy Knative 1.0, ktor\u00e1 je ur\u010den\u00e1 na vytv\u00e1ranie infra\u0161trukt\u00fary bezserverov\u00fdch v\u00fdpo\u010dtov be\u017eiacej na syst\u00e9me kontajnerovej izol\u00e1cie zalo\u017eenej na platforme Kubernetes. Okrem Google sa na v\u00fdvoji Knative podie\u013eaj\u00fa aj spolo\u010dnosti ako IBM, Red Hat, SAP a VMware. Uvedenie Knative 1.0 znamenalo stabiliz\u00e1ciu API na v\u00fdvoj aplik\u00e1ci\u00ed, ktor\u00e9 zostane nemenn\u00e9 a zabezpe\u010d\u00ed sp\u00e4tn\u00fa kompatibilitu. K\u00f3d projektu je nap\u00edsan\u00fd v jazyku Go a \u0161\u00edri sa pod licenciou Apache 2.0. <\/p>\n

Nab\u00eddnut\u00fd bezserverov\u00fd model v\u00fdvoja aplik\u00e1ci\u00ed v Knative poskytuje \u010fal\u0161iu \u00farove\u0148 abstrakcie pre cloudov\u00e9 syst\u00e9my, umo\u017e\u0148uj\u00facu vykon\u00e1va\u0165 funkcie ako slu\u017eby (FaaS, Functions as a service). Podstata bezserverov\u00e9ho modelu spo\u010d\u00edva v tom, \u017ee v\u00fdvoj\u00e1r implementuje logiku na \u00farovni jednotliv\u00fdch funkci\u00ed, pri\u010dom sa nemus\u00ed stara\u0165 o vytv\u00e1ranie a spr\u00e1vu infra\u0161trukt\u00fary potrebnej na spustenie aplik\u00e1ci\u00ed a nie je viazan\u00fd na konkr\u00e9tne serverov\u00e9 aplik\u00e1cie a potrebn\u00e9 cloudov\u00e9 prostredia. <\/p>\n

V\u00fdvoj prebieha bez vytv\u00e1rania monolitn\u00fdch aplik\u00e1ci\u00ed na \u00farovni pr\u00edpravy s\u00faboru mal\u00fdch jednotliv\u00fdch funkci\u00ed, z ktor\u00fdch ka\u017ed\u00e1 zabezpe\u010duje spracovanie ur\u010ditej udalosti a je navrhnut\u00e1 na nez\u00e1visl\u00e9 fungovanie bez viazania na prostredie (stateless, v\u00fdsledok nez\u00e1vis\u00ed od predch\u00e1dzaj\u00faceho stavu a obsahu FS). Funkcie sa sp\u00fa\u0161\u0165aj\u00fa iba v pr\u00edpade potreby a po spracovan\u00ed udalosti m\u00f4\u017eu okam\u017eite ukon\u010di\u0165 svoju \u010dinnos\u0165, t. j. na rozdiel od mikroslu\u017eieb nie je potrebn\u00e1 neust\u00e1la existencia spusten\u00fdch prostred\u00ed, ktor\u00e9 spotrebov\u00e1vaj\u00fa zdroje na vo\u013enobeh. <\/p>\n

Platforma Knative sama sp\u00fa\u0161\u0165a kontajnery pod\u013ea potreby, umiest\u0148uje do nich pripraven\u00e9 funkcie, organizuje spr\u00e1vu a zabezpe\u010duje \u0161k\u00e1lovanie prostred\u00ed potrebn\u00fdch na vykon\u00e1vanie t\u00fdchto funkci\u00ed. Platforma m\u00f4\u017ee by\u0165 nasaden\u00e1 na svojich zariadeniach bez viazania na extern\u00e9 cloudov\u00e9 slu\u017eby. Na spustenie je potrebn\u00fd len Kubernetes. Poskytovan\u00e9 s\u00fa prostriedky na podporu r\u00f4znych typov\u00fdch r\u00e1mcov, vr\u00e1tane Django, Ruby on Rails a Spring. Na spr\u00e1vu pr\u00e1ce platformy m\u00f4\u017ee by\u0165 pou\u017eit\u00fd rozhranie pr\u00edkazov\u00e9ho riadka. <\/p>\n

Platforma poskytuje dva z\u00e1kladn\u00e9 komponenty: <\/p>\n
