Unable to filter by tags

[John Dyer]

Hello,

 I am trying to filter instances by tags but its not working, I am getting nothing when I actually use the filter

func main() {

auth := aws.Auth{AccessKey: "xxxx", SecretKey: "xxxxxx"}

e := ec2.New(auth, aws.USEast)

filter := ec2.NewFilter()

filter.Add("backup_devices", "all")

resp, _ := e.DescribeInstances(nil, filter)

fmt.Println(resp)

}

Any idea what I am doing wrong?  Thanks in advance !

Are you sure the "backup_devices" is correct?

An example I have filter.Add("tag-key", "autobkup") which filters on tag keys.

tag-key is one of the available filter options. Have a look at this page -
http://docs.aws.amazon.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeInstances.html

That was it, I should have been doing 

filter.Add("tag-key", "backup_devices", "all")

Thanks!

Hi guys,

How about this one?

" tag:key=value - The key/value combination of a tag assigned to the resource, where tag:key is the tag's key."

I've tried without success this:

"...

    filter := ec2.NewFilter()

    filter.Add("tag:", tagKey, tagValue) 

..."

any tip on this?

Cheers,

Frank
