Question

I am using aws-sdk gem. i want to stop and start aws instance using 'aws-sdk' gem.

Below is my code to start an already stooped amazon instance but it is giving me error as SocketError: getaddrinfo: Name or service not known

ec2 = AWS::EC2::Client.new(
  region: 'us-west-2c',
  credentials: {:access_key_id => 'XXXXXXXXX',:secret_access_key => 'XXXXXXXXXXX'}
)



resp = ec2.start_instances({
  instance_ids: ["i-xxxxxx"], 
  additional_info: "String"
})

Please help

Thanks,

Answer 1

After a lot of research i came to know that i was specifying wrong region.

My region was 'us-west-2' and i was using region as 'us-west-2c' Which was not a region but availability zone.

After changing region to 'us-west-2' it works

AWS.config(
region: 'us-west-2',
access_key_id: 'xxxxxx',
secret_access_key: 'xxxxxxxxx'
)

ec2 = AWS::EC2::Client.new



resp = ec2.start_instances({
  instance_ids: ["i-xxxxxxxxx"], 
  additional_info: "String"
})
