根据过滤器停止EC2实例停止指定数量的EC2实例运行预先配置的 AWS FISSSM文档运行预定义的自动化运行手册限制对具有目标IAM角色的EC2实例的API操作对 Kubernetes 集群中的 Pod 进行压力测试 CPU

示例 AWS FIS实验模板

如果你使用的是 AWS FISAPI或者使用命令行工具来创建实验模板，则可以在 JavaScript 对象表示法 (JSON) 中构造模板。有关实验模板组件的更多信息，请参阅 AWS FIS实验模板组件。

要使用其中一个示例模板创建实验，请将其保存到JSON文件中（例如，my-template.json），替换中的占位符值 italics 使用您自己的值，然后运行以下create-experiment-template命令。


aws fis create-experiment-template --cli-input-json file://my-template.json

根据过滤器停止EC2实例

以下示例使用指定标签停止指定区域中所有正在运行的 Amazon EC2 实例VPC。两分钟后重启实例。


{
    "tags": {
        "Name": "StopEC2InstancesWithFilters"
    },
    "description": "Stop and restart all instances in us-east-1b with the tag env=prod in the specified VPC",
    "targets": {
        "myInstances": {
            "resourceType": "aws:ec2:instance",
            "resourceTags": {
                "env": "prod"
            },
            "filters": [
                {
                    "path": "Placement.AvailabilityZone",
                    "values": ["us-east-1b"]
                },
                {
                    "path": "State.Name",
                    "values": ["running"]
                },
                {
                    "path": "VpcId",
                    "values": [ "vpc-aabbcc11223344556"]
                }
            ],
            "selectionMode": "ALL"
        }
    },
    "actions": {
        "StopInstances": {
            "actionId": "aws:ec2:stop-instances",
            "description": "stop the instances",
            "parameters": {
                "startInstancesAfterDuration": "PT2M"
            },
            "targets": {
                "Instances": "myInstances"
            }
        }
    },
    "stopConditions": [
        {
            "source": "aws:cloudwatch:alarm",
            "value": "arn:aws:cloudwatch:us-east-1:111122223333:alarm:alarm-name"
        }
    ],
    "roleArn": "arn:aws:iam::111122223333:role/role-name"
}

停止指定数量的EC2实例

以下示例使用指定标签停止三个实例。 AWS FIS选择要随机停止的特定实例。两分钟后重启实例。


{
    "tags": {
        "Name": "StopEC2InstancesByCount"
    },
    "description": "Stop and restart three instances with the specified tag",
    "targets": {
        "myInstances": {
            "resourceType": "aws:ec2:instance",
            "resourceTags": {
                "env": "prod"
            },
            "selectionMode": "COUNT(3)"
        }
    },
    "actions": {
        "StopInstances": {
            "actionId": "aws:ec2:stop-instances",
            "description": "stop the instances",
            "parameters": {
                "startInstancesAfterDuration": "PT2M"
            },
            "targets": {
                "Instances": "myInstances"
            }
        }
    },
    "stopConditions": [
        {
            "source": "aws:cloudwatch:alarm",
            "value": "arn:aws:cloudwatch:us-east-1:111122223333:alarm:alarm-name"
        }
    ],
    "roleArn": "arn:aws:iam::111122223333:role/role-name"
}

运行预先配置的 AWS FISSSM文档

以下示例使用预先配置的在指定EC2实例上运行CPU故障注入 60 秒 AWS FISSSM文档，AWSFIS-Run-CPU-Stress。 AWS FIS监视实验两分钟。


{
    "tags": {
        "Name": "CPUStress"
    },
    "description": "Run a CPU fault injection on the specified instance",
    "targets": {
        "myInstance": {
            "resourceType": "aws:ec2:instance",
            "resourceArns": ["arn:aws:ec2:us-east-1:111122223333:instance/instance-id"],
            "selectionMode": "ALL"
        }
    },
    "actions": {
        "CPUStress": {
            "actionId": "aws:ssm:send-command",
            "description": "run cpu stress using ssm",
            "parameters": {
                "duration": "PT2M",

                "documentParameters": "{\"DurationSeconds\": \"60\", \"InstallDependencies\": \"True\", \"CPU\": \"0\"}"
            },
            "targets": {

            }
        }
    },
    "stopConditions": [
        {
            "source": "aws:cloudwatch:alarm",
            "value": "arn:aws:cloudwatch:us-east-1:111122223333:alarm:alarm-name"
        }
    ],
    "roleArn": "arn:aws:iam::111122223333:role/role-name"
}

运行预定义的自动化运行手册

以下示例SNS使用 Systems Manager 提供的运行手册向亚马逊发布通知，AWS-ublishSNSNotification P。该角色必须具有向指定SNS主题发布通知的权限。


{
    "description": "Publish event through SNS",
    "stopConditions": [
        {
            "source": "none"
        }
    ],
    "targets": {
    },
    "actions": {
        "sendToSns": {
            "actionId": "aws:ssm:start-automation-execution",
            "description": "Publish message to SNS",
            "parameters": {
                "documentArn": "arn:aws:ssm:us-east-1::document/AWS-PublishSNSNotification",
                "documentParameters": "{\"Message\": \"Hello, world\", \"TopicArn\": \"arn:aws:sns:us-east-1:111122223333:topic-name\"}",
                "maxDuration": "PT1M"
            },
            "targets": {
            }
        }
    },
    "roleArn": "arn:aws:iam::111122223333:role/role-name"
}

限制对具有目标IAM角色的EC2实例的API操作

以下示例限制了操作定义中API为目标定义中指定的IAM角色发出的API呼叫的 100% 的呼叫。

注意

如果您想定位属于 Auto Scaling 组成员的EC2实例，请使用 aws: ec2: asg-insufficient-instance-capacity-error 操作，改用 Auto Scaling 组进行定位。有关更多信息，请参阅。
