Implantar cargas de trabalho com suporte a Arc numa zona estendida: ContainerApps

Neste artigo, aprende como implementar uma ContainerApp compatível com Arc numa Zona Estendida. Para cargas de trabalho PaaS atualmente suportadas, consulte Ofertas de serviços para Zonas Estendidas do Azure. Para se familiarizar melhor com as Aplicações Container no Azure Arc, explore Azure Container Apps em Azure Arc Overview.

Pré-requisitos

Observação

Use o Local Estendido pretendido como sua variável de localização.

Como Começar

Se já estiver familiarizado com o assunto, pode saltar este parágrafo. Aqui estão tópicos importantes que pode querer ler antes de avançar com a criação:

Criar aplicativos de contêiner no AKS habilitado para Arc em zonas estendidas

Depois de criar o cluster AKS com Arc, utilize o seguinte script PowerShell para criar a sua Aplicação Container num cluster AKS numa Zona Estendida e conecte-a ao Kubernetes com Azure Arc.

Observação

Certifique-se de transferir corretamente os parâmetros das etapas do AKS com suporte para o Arc para o script.

Limpeza de recursos

Quando já não precisares dos recursos, elimina o grupo de recursos my-aks-cluster-group e todos os recursos que contém usando o comando azgroup delete .

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