Types ¶
type EC2Handler ¶
type EC2Handler struct{}
EC2Handler is a type that implements the EC2Service interface, providing methods to interact with EC2 instances.
func (*EC2Handler) CheckEC2Instances ¶
func (e *EC2Handler) CheckEC2Instances(ec2Svc ec2iface.EC2API)
CheckEC2Instances connects to AWS, performs a health check of EC2 instances, and lists the IDs of all active EC2 instances. It takes an EC2 service client as a parameter and queries EC2 instances, outputting their IDs.
func (*EC2Handler) NewAWSSession ¶
func (e *EC2Handler) NewAWSSession() (ec2iface.EC2API, error)
NewAWSSession creates a new AWS session and returns an EC2 service. It returns an EC2 service as an ec2iface.EC2API interface, which can be used to interact with EC2. If there is a problem creating the AWS session, it returns an error.
