Trechos de modelo do AWS OpsWorks

O AWS OpsWorks é um serviço de gerenciamento de aplicativos que simplifica uma grande variedade de tarefas, como a configuração de softwares, a implantação de aplicativos, a escalabilidade e o monitoramento. O AWS CloudFormation é um serviço de gerenciamento de recursos que você pode usar para gerenciar recursos do AWS OpsWorks, como pilhas, camadas, aplicativos e instâncias do AWS OpsWorks.

Exemplo de aplicativo PHP do AWS OpsWorks

O modelo da amostra a seguir implanta um aplicativo Web PHP do AWS OpsWorks de amostra armazenado no repositório Git público. A pilha AWS OpsWorks inclui dois servidores de aplicativos com um load balancer que distribui o tráfego de entrada igualmente entre os servidores. A pilha AWS OpsWorks também inclui um servidor back-end do banco de dados MySQL para armazenar dados. Para obter mais informações sobre o aplicação de exemplo do AWS OpsWorks, consulte Demonstração: aprenda os conceitos básicos do AWSAWS OpsWorks criando uma pilha de servidor de aplicações no Guia do usuário do AWS OpsWorks.

nota

As propriedades ServiceRoleArn e DefaultInstanceProfileArn fazem referência a perfis do IAM que são criados depois que você usa o AWS OpsWorks pela primeira vez.

O exemplo define os parâmetros MysqlRootPassword com a propriedade NoEcho definida como true. Se você definir o atributo NoEcho como true, o CloudFormation retornará o valor do parâmetro mascarado como asteriscos (*****) para todas as chamadas que descrevam a pilha ou os eventos da pilha.

Importante

Em vez de incorporar informações confidenciais diretamente em modelos do CloudFormation, recomendamos usar os parâmetros dinâmicos no modelo da pilha para fazer referência a informações confidenciais que são armazenadas e gerenciadas de forma externa ao CloudFormation, como no AWS Systems Manager Parameter Store ou no AWS Secrets Manager.

Para obter mais informações, consulte as práticas recomendadas do Não incorporar credenciais em seus modelos.
