Udviklerne af den frie PaaS-platform Cozystack har lavet projektet Talm, som har til form\u00e5l at forenkle konfigurationen af bare-metal servere til Talos Linux, et styresystem til at k\u00f8re Kubernetes, der har et Kubernetes-lignende API og konfigureres med en enkelt Yaml-manifest. Selvom Talm er designet til at beskrive den deklarative installation af Cozystack, er det ikke specifikt knyttet til denne platform og kan anvendes til at styre enhver konfiguration af Talos Linux. Projektet udvikles under MPL-licensen. <\/p>\n
Behovet for at udvikle endnu en konfigurationsmanager til Talos Linux skyldes fokus p\u00e5 bare-metal servere. Udviklerne \u00f8nskede at skabe det mest enkle interface, der ligner Helm og kubectl, som administratorer af Kubernetes er godt bekendte med. <\/p>\n
Da hver fysisk server har en anderledes konfiguration (MAC-adresser, interfaces og diske), er det n\u00f8dvendigt at have en separat konfigurationsfil for hver node. Der er brug for en enkel manager, der g\u00f8r det muligt at generere s\u00e5danne konfigurationsfiler baseret p\u00e5 den indsamlede information og deklarativt opdatere dem. <\/p>\n
Dette bruger dynamisk generering af konfigurationsfiler baseret p\u00e5 en given skabelon. Der findes f\u00e6rdige presets \u201egeneric\u201c og \u201ecozystack\u201c. Talm kan i genereringsfasen indsamle information fra Talos API og bruge det til de resulterende konfigurationer. Disse konfigurationsfiler indeholder ikke hemmeligheder, men kun \u00e6ndringer, hvilket g\u00f8r det nemt at opbevare dem i Git og styre dem deklarativt. <\/p>\n
I de fleste tilf\u00e6lde f\u00f8lger Talm strukturen af Helm, idet det opererer med begrebet chart, som beskriver skabeloner til generering af konfigurationer. Helm-lignende funktioner som lookup underst\u00f8ttes til direkte foresp\u00f8rgsel af Talos API og indsamling af yderligere metadata til generering af konfigurationsfiler ved hj\u00e6lp af \u201ego templates\u201c og sprig-biblioteket. <\/p>\n
Kommando: talm template -t templates\/controlplane.yaml -e 1.2.3.4 -n 1.2.3.4 > nodes\/srv1.yaml <\/p>\n
Foresp\u00f8rger noden \u201e1.2.3.4\u201c via API, genererer en ny konfigurationsfil til den fra skabelonen ved at inds\u00e6tte de n\u00f8dvendige data. Den resulterende konfigurationsfil kan straks anvendes med blot en kommando: talm apply -f nodes\/srv1.yaml <\/p>\n
I hver konfigurationsfil fasts\u00e6tter Talm sin egen modeline, der gemmer noderne og de skabeloner, de er baseret p\u00e5, for at g\u00f8re det nemt at anvende og opdatere uden behov for at angive yderligere indstillinger. Talm underst\u00f8tter de samme kommandoer som den oprindelige talosctl v\u00e6rkt\u00f8j, men giver mulighed for at overf\u00f8re konfigurationsfilen for noden, for eksempel: talm dashboard -f nodes\/srv1.yaml -f nodes\/srv2.yaml -f nodes\/srv3.yaml <\/p>\n
vil vise et interaktivt dashboard for alle tre noder. Og kommandoen: talm get routes -f nodes\/srv1.yaml <\/p>\n
vil udskrive en liste over ruter p\u00e5 noden \u201esrv1\u201c <\/p>\n
Hvis det er n\u00f8dvendigt, kan konfigurationsfilerne eksporteres med indstillingen \u201e--full\u201c til en separat PXE-server, hvilket g\u00f8r det muligt for noderne at downloade dem automatisk. P\u00e5 denne m\u00e5de bevarer Talm variabiliteten af bare-metal servere<\/a>, hvilket giver nem administration i overensstemmelse med bedste GitOps-praksis.
