Adding IP to Security Group

[Robert Pohl]

Hi, I'd like to add the IP for the newly created instance to some security groups, but I don't have any idea of how to get the IP for the current instance.

Any ideas if how the script should look like ?

Something like this?

after "deploy", "deploy:add_ip_to_sgs"
namespace :deploy do
  task :add_ip_to_sgs do
    #$ aws ec2 authorize-security-group-ingress --group-name my-sg --protocol tcp --port 8080 --cidr 203.0.113.0/24
  end

end

You can get the IP address of the instance from AWS Console.

Hi Robert,

 

Can you better describe what it is you're trying to do? Rubber already has a built-in mechanism for managing security groups, so you shouldn't need to add a new task for this. But to answer your immediate question, you can get the IP by looking up the InstanceItem. We do this all over the Rubber codebase, so feel free to grep for examples.

 

Here's one taken from the DNS template, searching by role name:

Here's another taken from the PostgreSQL template, searching by host name:
