Vzhledem k tomu, \u017ee ka\u017ed\u00fd fyzick\u00fd server m\u00e1 r\u016fznou konfiguraci (MAC adresy, rozhran\u00ed a disky), je nutn\u00e9 m\u00edt samostatn\u00fd konfigura\u010dn\u00ed soubor pro ka\u017ed\u00fd uzel.

Ve v\u011bt\u0161in\u011b p\u0159\u00edpad\u016f Talm opakuje strukturu Helm a pracuje s pojmem chart, kter\u00fd popisuje \u0161ablony pro generov\u00e1n\u00ed konfigurac\u00ed. Podporov\u00e1ny jsou Helm-podobn\u00e9 funkce lookup pro dotazov\u00e1n\u00ed Talos API p\u0159\u00edmo a shroma\u017e\u010fov\u00e1n\u00ed dal\u0161\u00edch metadat pro generov\u00e1n\u00ed konfigura\u010dn\u00edch soubor\u016f pomoc\u00ed \u201ego templ\u00e1t\u016f\u201c a knihovny sprig. <\/p>\n
