Distribuera Arc-aktiverad arbetsbelastning i en utökad zon: ContainerApps

I den här artikeln får du lära dig hur du distribuerar en Arc-aktiverad ContainerApp i en utökad zon. Information om PaaS-arbetsbelastningar som stöds finns i Service-erbjudanden för Azure utökade zoner. Om du vill lära dig mer om Container Apps på Azure Arc kan du utforska Azure Container Apps på Azure Arc Overview.

Förutsättningar

Anmärkning

Använd den avsedda utökade platsen som platsvariabel.

Om du redan är bekant med ämnet kan du hoppa över det här stycket. Här är viktiga ämnen som du kanske vill läsa innan du fortsätter att skapa:

Skapa Container-appar på Arc-aktiverad AKS i utökade zoner

När du har skapat det Arc-aktiverade AKS-klustret använder du följande PowerShell-skript för att skapa containerappen i ett AKS-kluster i en utökad zon och ansluta den till Azure Arc-aktiverade Kubernetes.

Anmärkning

Se till att överföra parametrarna från de Arc-aktiverade AKS-stegen korrekt till skriptet.

Rensa resurser

När du inte längre behöver resurserna tar du bort resursgruppen my-aks-cluster-group och alla resurser som den innehåller med kommandot az group delete .

az group delete --name my-aks-cluster-group
