Script para configurar o computador para gerenciar o cluster do Kubernetes habilitado para Azure Arc

Para se comunicar e configurar um cluster kubernetes habilitado para Azure Arc para o RAG do Edge, configure qualquer computador Windows com ferramentas como a CLI do Azure, o kubectl e o Helm. O computador precisa ser capaz de alcançar o cluster do Kubernetes.

Exemplo de script

Execute este script de exemplo para configurar um computador Windows para realizar as seguintes tarefas:

  1. Crie uma pasta.
  2. Baixe as extensões da CLI do Azure, helm, kubectl e CLI do Azure aksarc e kubernetes-extension.
  3. Entre no Azure usando a CLI do Azure com a assinatura e a ID do locatário.
  4. Conecte-se ao cluster kubernetes habilitado para Azure Arc.
  5. Salve credenciais para kubectl.
