Exemplos
Este exemplo define os seguintes recursos:
Uma virtual private cloud (VPC)
Um vSwitch
Um grupo de segurança
Um atraso personalizado (Sleep)
Duas instâncias ECS (CenterServer e OtherServer)
O exemplo cria instâncias ECS em uma VPC:
A instância CenterServer implanta o Nginx e envia sua chave pública para a OtherServer, permitindo acesso SSH sem senha. Em seguida, a OtherServer acessa o serviço Nginx na CenterServer.
-
Defina CreateDuration como 60 segundos para garantir que a CenterServer conclua a implantação antes que a OtherServer tente acessá-la.
NotaA criação da instância termina antes da conclusão da instalação do aplicativo. O atraso compensa esse tempo de inicialização.
