Unable to create an AWS instance in particular security group.

[Pradeep Chhetri]

Hello,

I am trying to create an instance in AWS in a particular security group.

server = conn.servers.create(:image_id => "#{@ami_id}",
                                           :flavor_id => "#{@instancetype}",
                                           :key_name => "#{@aws_ssh_key_name}",
                                           :groups => "Monitoring",
                                           :subnet_id => "#{@subnetid.shuffle.first}",
                                           :user_data => "#{user_data}")

where Monitoring is the name of the security group.

But when the machine comes up. It takes the "default" security group. I tried replacing "Monitoring" with the security-group-id but still I wasn't able to get Monitoring security group in the new instance. Can someone please help me out.


Thank you,

- Pradeep

Finally figured out that I should use :security_group_ids => ["sg-xxxxxxx"].

You definitely can use the group names, but it needs to be an array - :groups => ['Monitoring'], even if there's only the one group.

Hi Fred,

As you said, I tried passing as an array as well. It didn't work. It
took the "default" Security group only. The machine is inside VPC.
Should it make any difference ? Do I need to mentioned vpc-id anywhere ?

[Frederick Cheung]

Ah, may well change things - I've never used that before. Security groups are different with a vpc so it wouldn't surprise me if there was a difference

For now, security_group_ids is working for me nicely. Thank you Fred.

Hi Pradeep,

Below is the code which is working fine for me .

  instance = compute.servers.create ({

      :flavor_id => opts[:flavor],

      :key_name => opts[:key],

      :image_id => opts[:ami],

      :security_group_ids => opts[:security_group],

      :subnet_id => opts[:subnet_id],

      :tags => {"Name" => opts[:name]}

     })

So you should use security_group_ids in your code. Those are unique and different for VPC and EC2 classic .
