AWS OpsWorks Construct Library

This module is part of the AWS Cloud Development Kit project.

import opsworks "github.com/aws/aws-cdk-go/awscdk"

There are no official hand-written (L2) constructs for this service yet. Here are some suggestions on how to proceed:

There are no hand-written (L2) constructs for this service yet. However, you can still use the automatically generated L1 constructs, and use this service exactly as you would using CloudFormation directly.

For more information on the resources and properties available for this service, see the CloudFormation documentation for AWS::OpsWorks.

(Read the CDK Contributing Guide and submit an RFC if you are interested in contributing to this construct library.)

	// Adds an override to the synthesized CloudFormation resource.

	// If there is an array as part of the nesting, specify the index in the path.
	//
	// To include a literal `.` in the property name, prefix with a `\`. In most
	// programming languages you will need to write this as `"\\."` because the
	// `\` itself will need to be escaped.

A CloudFormation `AWS::OpsWorks::App`.

Creates an app for a specified stack. For more information, see [Creating Apps](https://docs.aws.amazon.com/opsworks/latest/userguide/workingapps-creating.html) .

*Required Permissions* : To use this action, an IAM user must have a Manage permissions level for the stack, or an attached policy that explicitly grants permissions. For more information on user permissions, see [Managing User Permissions](https://docs.aws.amazon.com/opsworks/latest/userguide/opsworks-security-users.html) .

Creates an instance in a specified stack. For more information, see [Adding an Instance to a Layer](https://docs.aws.amazon.com/opsworks/latest/userguide/workinginstances-add.html) .

*Required Permissions* : To use this action, an IAM user must have a Manage permissions level for the stack, or an attached policy that explicitly grants permissions. For more information on user permissions, see [Managing User Permissions](https://docs.aws.amazon.com/opsworks/latest/userguide/opsworks-security-users.html) .

A CloudFormation `AWS::OpsWorks::Layer`.

Creates a layer. For more information, see [How to Create a Layer](https://docs.aws.amazon.com/opsworks/latest/userguide/workinglayers-basics-create.html) .

> You should use *CreateLayer* for noncustom layer types such as PHP App Server only if the stack does not have an existing layer of that type. A stack can have at most one instance of each noncustom layer; if you attempt to create a second instance, *CreateLayer* fails. A stack can have an arbitrary number of custom layers, so you can call *CreateLayer* as many times as you like for that layer type.

*Required Permissions* : To use this action, an IAM user must have a Manage permissions level for the stack, or an attached policy that explicitly grants permissions. For more information on user permissions, see [Managing User Permissions](https://docs.aws.amazon.com/opsworks/latest/userguide/opsworks-security-users.html) .

AWS OpsWorks Stacks supports five lifecycle events: *setup* , *configuration* , *deploy* , *undeploy* , and *shutdown* .

For each layer, AWS OpsWorks Stacks runs a set of standard recipes for each event. In addition, you can provide custom recipes for any or all layers and events. AWS OpsWorks Stacks runs custom event recipes after the standard recipes. `LayerCustomRecipes` specifies the custom recipes for a particular layer to be run in response to each of the five events.

To specify a recipe, use the cookbook's directory name in the repository followed by two colons and the recipe name, which is the recipe's file name without the .rb extension. For example: phpapp2::dbsetup specifies the dbsetup.rb recipe in the repository's phpapp2 folder.

	//
	// - True - AWS OpsWorks Stacks automatically associates the appropriate built-in security group with each layer (default setting). You can associate additional security groups with a layer after you create it, but you cannot delete the built-in security group.
	// - False - AWS OpsWorks Stacks does not associate built-in security groups with layers. You must create appropriate EC2 security groups and associate a security group with each layer that you create. However, you can still manually associate a built-in security group with a layer on creation; custom security groups are required only for those layers that need custom settings.

	// The ID of the VPC that the stack is to be launched into.
	//
	// The VPC must be in the stack's region. All instances are launched into this VPC. You cannot change the ID later.
	//
	// - If your account supports EC2-Classic, the default value is `no VPC` .
	// - If your account does not support EC2-Classic, the default value is the default VPC for the specified region.
	//
	// If the VPC ID corresponds to a default VPC and you have specified either the `DefaultAvailabilityZone` or the `DefaultSubnetId` parameter only, AWS OpsWorks Stacks infers the value of the other parameter. If you specify neither parameter, AWS OpsWorks Stacks sets these parameters to the first valid Availability Zone for the specified region and the corresponding default VPC subnet ID, respectively.
	//
	// If you specify a nondefault VPC ID, note the following:
	//
	// - It must belong to a VPC in your account that is in the specified region.
	// - You must specify a value for `DefaultSubnetId` .
	//
	// For more information about how to use AWS OpsWorks Stacks with a VPC, see [Running a Stack in a VPC](https://docs.aws.amazon.com/opsworks/latest/userguide/workingstacks-vpc.html) .
