Types

type AmazonRenderer

type AmazonRenderer struct{}

func (AmazonRenderer) Render

func (AmazonRenderer) Render(cfg cloudinit.CloudConfig, os jujuos.OSType) ([]byte, error)

type AvailabilityZoner

type AvailabilityZoner interface {
	AvailabilityZone() (string, bool)
}

AvailabilityZoner defines a institute interface for getting an az from an instance.

type SecurityGroupCleaner

type SecurityGroupCleaner interface {
	// DeleteSecurityGroup deletes security group on the provider.
	DeleteSecurityGroup(group amzec2.SecurityGroup) (resp *amzec2.SimpleResp, err error)
}

SecurityGroupCleaner defines provider instance methods needed to delete a security group.

type SubnetMatcher

type SubnetMatcher interface {
	Match(ec2.Subnet) bool
}

func CreateSubnetMatcher

func CreateSubnetMatcher(subnetQuery string) SubnetMatcher

CreateSubnetMatcher creates a SubnetMatcher that handles a particular method of comparison based on the content of the subnet query. If the query looks like a CIDR, then we will match subnets with the same CIDR. If it follows the syntax of a "subnet-XXXX" then we will match the Subnet ID. Everything else is just matched as a Name.
