本文主要介绍原子动作相关demo。 ## API动作 API相关动作包括VOS::ExecuteAPI、VOS::WaitFor和VOS::CheckFor。 ### VOS::ExecuteAPI示例 ```JSON { "Tasks": [ { "Name": "RebootInstance", "Description": "{\"zh-cn\":\"重启实例\",\"en\":\"RebootInstance\"}", "Action": "VOS::ExecuteAPI", "Parameters": { "APIInfo": { "Service": "ecs", "APIName": "RebootInstance", "Version": "2020-04-01", "Parameters": { "ForceStop": "Value1", "InstanceId": "Value2" } } }, "Outputs": { "Result1": { "Type": "List", "Value": [ ] } } } ] } ``` ### VOS::WaitFor示例 ```JSON { "Tasks": [ { "Name": "untilInstanceRunningOrStopped", "Description": "等待ECS实例至运行中或停止中状态", "Action": "VOS::WaitFor", "Parameters": { "APIInfo": { "Service": "ecs", "APIName": "DescribeInstances", "Version": "2020-04-01", "Parameters": { "InstanceIds": "{{ [.\"describeVolumeStatus.attachedInstanceId\"] }}" }, "DesiredValues": [ "RUNNING", "STOPPED" ], "NotDesiredValues": [ "STOPPING" ], "ValueSelector": "{{ [.Instances[].Status] }}" } } } ] } ``` ### VOS::CheckFor示例 ```JSON { "Tasks": [ { "Name": "checkInstanceReady", "Description": "检查实例状态", "Action": "VOS::CheckFor", "Parameters": { "APIInfo": { "Service": "ecs", "APIName": "DescribeInstances", "Version": "2020-04-01", "Parameters": { "InstanceIds": "{{ [.instanceId] }}" }, "DesiredValues": [ "RUNNING", "STOPPED" ], "NotDesiredValues": [ "ERROR" ], "ValueSelector": "{{ [.Instances[].Status] }}" } } } ] } ``` ## PeriodTriggerInfo（触发类） ### VOS::PeriodicTrigger示例 ```JSON { "Tasks": [ { "Name": "periodicTask", "Action": "VOS::PeriodicTrigger", "Description": "通过指定任务类型和周期表达式按计划触发任务", "Parameters": { "PeriodTriggerInfo": { "RepeatMode": "{{ .repeatMode }}", "LaunchTime": "{{ .launchTime }}", "RecurrenceEndTime": "{{ .recurrenceEndTime }}", "Frequency": "{{ .frequency }}" } } } ] } ``` ## ChoiceInfo（控制类） ChoiceInfo包括VOS::Choice和VOS::SelectTargetInstances ### VOS::Choice示例 ```JSON { "Tasks": [ { "Name": "whetherToDeleteLaunchTemplateVersion", "Description": "是否删除启动模版的原最新版本", "Action": "VOS::Choice", "Parameters": { "ChoiceInfo": { "Condition": [ { "When": { "FN::Equals": [ "{{ .deleteSourceTemplateVersion }}", true ] }, "Next": "whetherToModifyTemplateDefaultVersion" } ], "Default": "VOS::END" } } } ] } ``` ### VOS::SelectTargetInstances示例 **使用Action的自定义模版** ```JSON { "Parameters": { "targets":{ "Type":"Map" } "ForceStop": { "Type": "Boolean" } }, "Tasks": [ { "Name": "getInstance", "Action": "VOS::SelectTargetInstances", "Parameters": { "Filters": "{{ targets }}" }, "Outputs": { "instanceIds": { "Type": "List", "ValueSelector": "Instances.Instance[].InstanceId" } }, "Description": "{\"zh-cn\":\"选择实例\",\"en\":\"SelectTargetInstances\"}" }, { "Name": "RebootInstances", "ActionId": "ac-ycc8brgqe5f10****", "Parameters": { "InstanceId": "{{ VOS::LoopItem }}", "ForceStop": "{{ .ForceStop }}" }, "Outputs": { "InstanceStatus": { "Type": "String", "Value": "{{ .InstanceStatus }}" } }, "Loop": { "LoopItem": "{{ getInstance.instanceIds }}", "Outputs": { "LoopInstanceStatus": { "SelectedOutputFiled": "InstanceStatus" } }, "Concurrency": 1 }, "Description": "{\"zh-cn\":\"批量重启实例\",\"en\":\"RebootInstances\"}" } ], "Outputs": { "InstanceStatus": { "Type": "List", "Value": "{{ .\"RebootInstances.LoopInstanceStatus\" }}" } } } ``` **调用传参：** Type表示选择实例的方式，取值： * Tags：按照标签键值对选择实例。 * Project：选择指定项目下的所有实例。 * All：选择所有实例。 ```JSON {"targets":{"Type":"Tags","Tags":[{"Key":"tagKey1","Value":"tagValue1"}]}} {"targets":{"Type":"Project","Project":"projectName"}} {"targets":{"Type":"All"}} ``` ## 执行函数 ### VOS::InvokeInnerFunction示例当前已预置的计算Function如下： * FN::Equals * FN::Now * FN::AddMinute * FN::FormatUTCTime * FN::ExecuteJQExpression * FN::GetExecutionId ```JSON { "Tasks": [ { "Name": "getSplitInstanceIdList", "Description": "获取分割后的实例ID列表", "Action": "VOS::InvokeInnerFunction", "Parameters": { "FunctionName": "FN::ExecuteJQExpression", "Input": " def split($array; $len):\n if $array | length > $len then $array | .[0:$len] as $temp | [$temp] + split(.[$len:]; $len) else [$array] end; split(.InstanceIds; 100) " }, "Outputs": { "instanceIdList": { "Type": "List", "Value": "{{ . }}" } } } ] } ``` ## 嵌套 ### VOS::InvokeTemplate示例 ```JSON "Tasks": [ { "Name": "BulkyModifyInstanceVpcAttribute", "Action": "VOS::InvokeTemplate", "Description": "{\"zh-cn\":\"批量修改实例VPC信息\",\"en\":\"BulkyModifyInstanceVpcAttribute\"}", "Parameters": { "TemplateId": "tl-ydsu3hnja4kkk1k****", "VPCInfo": "{{ VOS::LoopItem }}", "NeedStart": "{{ .NeedStart }}" }, "Outputs": { "NetworkInterfaceId": { "Type": "String", "Value": "{{ .NetworkInterfaceId }}" } }, "Loop": { "LoopItem": "{{ .AllVPCInfo }}", "Outputs": { "NetworkInterfaceIds": { "SelectedOutputFiled": "NetworkInterfaceId" } }, "RateControl": "{{ .RateControl }}" } } ] ```
