示例1: InstanceStateRefreshFunc
// InstanceStateRefreshFunc returns a resource.StateRefreshFunc that is used to watch
// an EC2 instance.
func InstanceStateRefreshFunc(conn *ec2.EC2, instanceID string) resource.StateRefreshFunc {
return func() (interface{}, string, error) {
resp, err := conn.DescribeInstances(&ec2.DescribeInstancesRequest{
InstanceIDs: []string{instanceID},
})
if err != nil {
if ec2err, ok := err.(aws.APIError); ok && ec2err.Code == "InvalidInstanceID.NotFound" {
// Set this to nil as if we didn't find anything.
resp = nil
} else {
log.Printf("Error on InstanceStateRefresh: %s", err)
return nil, "", err
}
}
if resp == nil || len(resp.Reservations) == 0 || len(resp.Reservations[0].Instances) == 0 {
// Sometimes AWS just has consistency issues and doesn't see
// our instance yet. Return an empty state.
return nil, "", nil
}
i := &resp.Reservations[0].Instances[0]
return i, *i.State.Name, nil
}
