aws

The Amazon Web Services (AWS) provider manages multiple types of resources.

aws_ec2

AWS Instances can be provisioned using this resource.

• Topology Example
• Topology Example w/ VPC
• aws_ec2 module

EC2 Inventory Generation

If an instance has a public IP attached, its hostname in public DNS, if available, will be provided in the generated Ansible inventory file, and if not the public IP address will be provided.

For instances which have a private IP address for VPC usage, the private IP address will be provided since private EC2 DNS hostnames (e.g. ip-10-0-0-1.ec2.internal) will not typically be resolvable outside of AWS.

For instances with both a public and private IP address, the public address is always provided instead of the private address, so as to avoid duplicate runs of Ansible on the same host via the generated inventory file.

aws_ec2_key

AWS SSH keys can be added using this resource.

• Topology Example
• ec2_key module

Note

This resource will not be torn down during a destroy action. This is because other resources may depend on the now existing resource.

aws_s3

AWS Simple Storage Service buckets can be provisioned using this resource.

• Topology Example
• aws_s3 module

Note

This resource will not be torn down during a destroy action. This is because other resources may depend on the now existing resource.

aws_sg

AWS Security Groups can be provisioned using this resource.

• Topology Example
• ec2_group module

Note

This resource will not be torn down during a destroy action. This is because other resources may depend on the now existing resource.

Additional Dependencies

No additional dependencies are required for the AWS Provider.

Credentials Management

AWS provides several ways to provide credentials. LinchPin supports some of these methods for passing credentials for use with AWS resources.

One method to provide AWS credentials that can be loaded by LinchPin is to use the INI format that the AWS CLI tool uses.

Environment Variables

LinchPin honors the AWS environment variables

Provisioning

Provisioning with credentials uses the --creds-path option.

$ linchpin -v --creds-path ~/.config/aws up

Alternatively, the credentials path can be set as an environment variable,

$ export CREDS_PATH="~/.config/aws"
$ linchpin -v up
