Como criar um perfil de instância

O comando create-instance-profile, apresentado a seguir, cria um perfil de instância denominado Webserver.

aws iam create-instance-profile \
    --instance-profile-name Webserver

Saída:

{
    "InstanceProfile": {
        "InstanceProfileId": "AIPAJMBYC7DLSPEXAMPLE",
        "Roles": [],
        "CreateDate": "2015-03-09T20:33:19.626Z",
        "InstanceProfileName": "Webserver",
        "Path": "/",
        "Arn": "arn:aws:iam::123456789012:instance-profile/Webserver"
    }
}

Para adicionar um perfil a um perfil de instância, use o comando add-role-to-instance-profile.

Para obter mais informações, consulte Como usar uma IAM função para conceder permissões a aplicativos executados em EC2 instâncias da Amazon no Guia AWS IAM do usuário.

  const { InstanceProfile } = await iamClient.send(
    new CreateInstanceProfileCommand({
      InstanceProfileName: NAMES.ssmOnlyInstanceProfileName,
    }),
  );
  await waitUntilInstanceProfileExists(
    { client: iamClient },
    { InstanceProfileName: NAMES.ssmOnlyInstanceProfileName },
  );

Exemplo 1: Esse exemplo cria um novo perfil de IAM instância chamadoProfileForDevEC2Instance. Você deve executar o Add-IAMRoleToInstanceProfile comando separadamente para associar o perfil da instância a uma IAM função existente que forneça permissões para a instância. Por fim, anexe o perfil da EC2 instância a uma instância ao executá-la. Para isso, use o cmdlet New-EC2Instance com o parâmetro InstanceProfile_Arn ou InstanceProfile_Name.

New-IAMInstanceProfile -InstanceProfileName ProfileForDevEC2Instance

Saída:

Arn                 : arn:aws:iam::123456789012:instance-profile/ProfileForDevEC2Instance
CreateDate          : 4/14/2015 11:31:39 AM
InstanceProfileId   : DYMFXL556EY46EXAMPLE1
InstanceProfileName : ProfileForDevEC2Instance
Path                : /
Roles               : {}

Este exemplo cria uma política, um perfil e um perfil de instância e vincula uns aos outros.
