Overview

Package autoscaling provides the client and types for making API requests to Auto Scaling.

Amazon EC2 Auto Scaling is designed to automatically launch and terminate EC2 instances based on user-defined scaling policies, scheduled actions, and health checks.

For more information, see the Amazon EC2 Auto Scaling User Guide (https://docs.aws.amazon.com/autoscaling/ec2/userguide/what-is-amazon-ec2-auto-scaling.html) and the Amazon EC2 Auto Scaling API Reference (https://docs.aws.amazon.com/autoscaling/ec2/APIReference/Welcome.html).

See https://docs.aws.amazon.com/goto/WebAPI/autoscaling-2011-01-01 for more information on this service.

See autoscaling package documentation for more information. https://docs.aws.amazon.com/sdk-for-go/api/service/autoscaling/

Using the Client

To contact Auto Scaling with the SDK use the New function to create a new service client. With that client you can make API requests to the service. These clients are safe to use concurrently.

See the SDK's documentation for more information on how to use the SDK. https://docs.aws.amazon.com/sdk-for-go/api/

See aws.Config documentation for more information on configuring SDK clients. https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config

See the Auto Scaling client AutoScaling for more information on creating client for this service. https://docs.aws.amazon.com/sdk-for-go/api/service/autoscaling/#New

type AutoScaling 

type AutoScaling struct {
	*client.Client
}

AutoScaling provides the API operation methods for making requests to Auto Scaling. See this package's package overview docs for details on the service.

AutoScaling methods are safe to use concurrently. It is not safe to modify mutate any of the struct's properties though.

func New 

func New(p client.ConfigProvider, cfgs ...*aws.Config) *AutoScaling

New creates a new instance of the AutoScaling client with a session. If additional configuration is needed for the client instance use the optional aws.Config parameter to add your extra config.

Example: 

mySession := session.Must(session.NewSession())

// Create a AutoScaling client from just a session.
svc := autoscaling.New(mySession)

// Create a AutoScaling client with additional configuration
svc := autoscaling.New(mySession, aws.NewConfig().WithRegion("us-west-2"))

func (*AutoScaling) AttachInstances 

func (c *AutoScaling) AttachInstances(input *AttachInstancesInput) (*AttachInstancesOutput, error)

AttachInstances API operation for Auto Scaling.

Attaches one or more EC2 instances to the specified Auto Scaling group.

When you attach instances, Amazon EC2 Auto Scaling increases the desired capacity of the group by the number of instances being attached. If the number of instances being attached plus the desired capacity of the group exceeds the maximum size of the group, the operation fails.

If there is a Classic Load Balancer attached to your Auto Scaling group, the instances are also registered with the load balancer. If there are target groups attached to your Auto Scaling group, the instances are also registered with the target groups.

For more information, see Detach or attach instances (https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-detach-attach-instances.html) in the Amazon EC2 Auto Scaling User Guide.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Auto Scaling's API operation AttachInstances for usage and error information.

Returned Error Codes:

  • ErrCodeResourceContentionFault "ResourceContention" You already have a pending update to an Amazon EC2 Auto Scaling resource (for example, an Auto Scaling group, instance, or load balancer).

  • ErrCodeServiceLinkedRoleFailure "ServiceLinkedRoleFailure" The service-linked role is not yet ready for use.

	}

	fmt.Println(result)
}

Output:

func (*AutoScaling) AttachInstancesRequest 

func (c *AutoScaling) AttachInstancesRequest(input *AttachInstancesInput) (req *request.Request, output *AttachInstancesOutput)

AttachInstancesRequest generates a "aws/request.Request" representing the client's request for the AttachInstances operation. The "output" return value will be populated with the request's response once the request completes successfully.

Use "Send" method on the returned Request to send the API call to the service. the "output" return value is not valid until after Send returns without error.

See AttachInstances for more information on using the AttachInstances API call, and error handling.

This method is useful when you want to inject custom logic or configuration into the SDK's request lifecycle. Such as custom headers, or retry logic. 

// Example sending a request using the AttachInstancesRequest method.
req, resp := client.AttachInstancesRequest(params)

err := req.Send()
if err == nil { // resp is now filled
    fmt.Println(resp)

AttachInstancesWithContext is the same as AttachInstances with the addition of the ability to pass a context and additional request options.

See AttachInstances for details on how to use this API operation.

The context must be non-nil and will be used for request cancellation. If the context is nil a panic will occur. In the future the SDK may create sub-contexts for http.Requests. See https://golang.org/pkg/context/ for more information on using Contexts.

func (*AutoScaling) AttachLoadBalancerTargetGroups added in v1.4.1 

func (c *AutoScaling) AttachLoadBalancerTargetGroups(input *AttachLoadBalancerTargetGroupsInput) (*AttachLoadBalancerTargetGroupsOutput, error)

AttachLoadBalancerTargetGroups API operation for Auto Scaling.

This API operation is superseded by AttachTrafficSources, which can attach multiple traffic sources types. We recommend using AttachTrafficSources to simplify how you manage traffic sources. However, we continue to support AttachLoadBalancerTargetGroups. You can use both the original AttachLoadBalancerTargetGroups API operation and AttachTrafficSources on the same Auto Scaling group.

Attaches one or more target groups to the specified Auto Scaling group.

This operation is used with the following load balancer types:

  • Application Load Balancer - Operates at the application layer (layer 7) and supports HTTP and HTTPS.

  • Network Load Balancer - Operates at the transport layer (layer 4) and supports TCP, TLS, and UDP.

  • Gateway Load Balancer - Operates at the network layer (layer 3).

To describe the target groups for an Auto Scaling group, call the DescribeLoadBalancerTargetGroups API. To detach the target group from the Auto Scaling group, call the DetachLoadBalancerTargetGroups API.

This operation is additive and does not detach existing target groups or Classic Load Balancers from the Auto Scaling group.

For more information, see Use Elastic Load Balancing to distribute traffic across the instances in your Auto Scaling group (https://docs.aws.amazon.com/autoscaling/ec2/userguide/autoscaling-load-balancer.html) in the Amazon EC2 Auto Scaling User Guide.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

func (*AutoScaling) CompleteLifecycleAction 

func (c *AutoScaling) CompleteLifecycleAction(input *CompleteLifecycleActionInput) (*CompleteLifecycleActionOutput, error)

CompleteLifecycleAction API operation for Auto Scaling.

Completes the lifecycle action for the specified token or instance with the specified result.

This step is a part of the procedure for adding a lifecycle hook to an Auto Scaling group:

(Optional) Create a launch template or launch configuration with a user data script that runs while an instance is in a wait state due to a lifecycle hook.

(Optional) Create a Lambda function and a rule that allows Amazon EventBridge to invoke your Lambda function when an instance is put into a wait state due to a lifecycle hook.

(Optional) Create a notification target and an IAM role. The target can be either an Amazon SQS queue or an Amazon SNS topic. The role allows Amazon EC2 Auto Scaling to publish lifecycle notifications to the target.

Create the lifecycle hook. Specify whether the hook is used when the instances launch or terminate.

If you need more time, record the lifecycle action heartbeat to keep the instance in a wait state.

If you finish before the timeout period ends, send a callback by using the CompleteLifecycleAction API call.

For more information, see Complete a lifecycle action (https://docs.aws.amazon.com/autoscaling/ec2/userguide/completing-lifecycle-hooks.html) in the Amazon EC2 Auto Scaling User Guide.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Auto Scaling's API operation CompleteLifecycleAction for usage and error information.

Returned Error Codes:

func (*AutoScaling) CreateAutoScalingGroup 

func (c *AutoScaling) CreateAutoScalingGroup(input *CreateAutoScalingGroupInput) (*CreateAutoScalingGroupOutput, error)

CreateAutoScalingGroup API operation for Auto Scaling.

We strongly recommend using a launch template when calling this operation to ensure full functionality for Amazon EC2 Auto Scaling and Amazon EC2.

Creates an Auto Scaling group with the specified name and attributes.

If you exceed your maximum limit of Auto Scaling groups, the call fails. To query this limit, call the DescribeAccountLimits API. For information about updating this limit, see Quotas for Amazon EC2 Auto Scaling (https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-quotas.html) in the Amazon EC2 Auto Scaling User Guide.

If you're new to Amazon EC2 Auto Scaling, see the introductory tutorials in Get started with Amazon EC2 Auto Scaling (https://docs.aws.amazon.com/autoscaling/ec2/userguide/get-started-with-ec2-auto-scaling.html) in the Amazon EC2 Auto Scaling User Guide.

Every Auto Scaling group has three size properties (DesiredCapacity, MaxSize, and MinSize). Usually, you set these sizes based on a specific number of instances. However, if you configure a mixed instances policy that defines weights for the instance types, you must specify these sizes with the same units that you use for weighting instances.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Auto Scaling's API operation CreateAutoScalingGroup for usage and error information.

Output:

func (*AutoScaling) CreateAutoScalingGroupRequest 

func (c *AutoScaling) CreateAutoScalingGroupRequest(input *CreateAutoScalingGroupInput) (req *request.Request, output *CreateAutoScalingGroupOutput)

CreateAutoScalingGroupRequest generates a "aws/request.Request" representing the client's request for the CreateAutoScalingGroup operation. The "output" return value will be populated with the request's response once the request completes successfully.

Use "Send" method on the returned Request to send the API call to the service. the "output" return value is not valid until after Send returns without error.

See CreateAutoScalingGroup for more information on using the CreateAutoScalingGroup API call, and error handling.

This method is useful when you want to inject custom logic or configuration into the SDK's request lifecycle. Such as custom headers, or retry logic. 

// Example sending a request using the CreateAutoScalingGroupRequest method.
req, resp := client.CreateAutoScalingGroupRequest(params)

err := req.Send()
if err == nil { // resp is now filled
    fmt.Println(resp)
}

func (*AutoScaling) CreateAutoScalingGroupWithContext added in v1.8.0 

func (c *AutoScaling) CreateAutoScalingGroupWithContext(ctx aws.Context, input *CreateAutoScalingGroupInput, opts ...request.Option) (*CreateAutoScalingGroupOutput, error)

CreateAutoScalingGroupWithContext is the same as CreateAutoScalingGroup with the addition of the ability to pass a context and additional request options.

See CreateAutoScalingGroup for details on how to use this API operation.

The context must be non-nil and will be used for request cancellation. If the context is nil a panic will occur. In the future the SDK may create sub-contexts for http.Requests. See https://golang.org/pkg/context/ for more information on using Contexts.

func (*AutoScaling) CreateLaunchConfiguration 

func (c *AutoScaling) CreateLaunchConfiguration(input *CreateLaunchConfigurationInput) (*CreateLaunchConfigurationOutput, error)

CreateLaunchConfiguration API operation for Auto Scaling.

Creates a launch configuration.

If you exceed your maximum limit of launch configurations, the call fails. To query this limit, call the DescribeAccountLimits API. For information about updating this limit, see Quotas for Amazon EC2 Auto Scaling (https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-quotas.html) in the Amazon EC2 Auto Scaling User Guide.

For more information, see Launch configurations (https://docs.aws.amazon.com/autoscaling/ec2/userguide/launch-configurations.html) in the Amazon EC2 Auto Scaling User Guide.

Amazon EC2 Auto Scaling configures instances launched as part of an Auto Scaling group using either a launch template or a launch configuration. We strongly recommend that you do not use launch configurations. They do not provide full functionality for Amazon EC2 Auto Scaling or Amazon EC2. For information about using launch templates, see Launch templates (https://docs.aws.amazon.com/autoscaling/ec2/userguide/launch-templates.html) in the Amazon EC2 Auto Scaling User Guide.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for Auto Scaling's API operation CreateLaunchConfiguration for usage and error information.

Returned Error Codes:

  • ErrCodeAlreadyExistsFault "AlreadyExists" You already have an Auto Scaling group or launch configuration with this name.

  • ErrCodeLimitExceededFault "LimitExceeded" You have already reached a limit for your Amazon EC2 Auto Scaling resources (for example, Auto Scaling groups, launch configurations, or lifecycle hooks). For more information, see DescribeAccountLimits (https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_DescribeAccountLimits.html) in the Amazon EC2 Auto Scaling API Reference.

  • ErrCodeResourceContentionFault "ResourceContention" You already have a pending update to an Amazon EC2 Auto Scaling resource (for example, an Auto Scaling group, instance, or load balancer).
