end

#bootstrap_many(min_servers = 1, max_servers = nil, new_attributes = {}) ⇒ Object

Bootstrap between m and n servers with the server options specified in new_attributes. Equivalent to this loop, but happens in 1 AWS request and the machines’ spinup will happen in parallel:

1.upto(n).map { bootstrap(new_attributes) }

See the AWS RunInstances API.

Create between m and n servers with the server options specified in new_attributes. Equivalent to this loop, but happens in 1 request:

1.upto(n).map { create(new_attributes) }

#get(server_id) ⇒ Object

Used to retrieve a server

server_id is required to get the associated server information.

You can run the following command to get the details: AWS.servers.get(“i-5c973972”)

Returns
