error while deploying rails app to ec2 using rubber gem `response_call': Expected(200) <=> Actual(400 Bad Request) (Excon::Errors::BadRequest)

Question

when I do cap rubber:create_staging, I am getting the following error when rubber tries to create ec2 instance. Am I missing any configuration setting?

Answer 1

I'm having the same problem. It looks like it is covered as Issue #362 on the Rubber github page: https://github.com/rubber/rubber/issues/362

Answer 2

I downgraded my excon version from 0.22.01 to 0.21.0

Adding this in the gem file and then bundle, fixed the problem. gem 'excon', '~> 0.21.0'

I am not aware of the root cause though.

Answer 3

I solved this by updating the fog gem by running:

bundle update fog

Aparently I was very outdated running fog 1.9.0. Now im running 1.23.0 and got to successfully deploy to EC2 by following Rubber's Railscasts (http://railscasts.com/episodes/347-rubber-and-amazon-ec2)

This also updated the following gems to these versions:

• fog-core 1.23.0
• net-scp 1.2.1
• fog-json 1.0.0
• List item
• inflecto 0.0.2
• fog-brightbox 0.1.1
• fog-softlayer 0.3.11
• ipaddress 0.8.0
• mini_portile 0.6.0

Nokogiri depends on libxml2-2.9.0 library so be sure to have that installed

Hope it helps!!
