aws has no compute service

[jgrammen-agilitypr]

Hello,

I am trying to use fog to connect to ec2 and get a list of servers and their instance_id's
fog-aws gem is installed, but an error occurs that I do not understand.

Any help would be much appreciated

code snippet

require 'fog/aws'
ec2 = Fog::Compute.new(
  :provider => 'Aws'
)

error

Hello @jgrammen-agilitypr.

The provider should be AWS instead of Aws

[jgrammen-agilitypr]

Update the code as per the correction

ec2 = Fog::Compute.new(
  :provider => 'AWS'
)

same error

/var/lib/gems/2.3.0/gems/fog-core-1.45.0/lib/fog/core/services_mixin.rb:18:in `rescue in new': aws has no compute service (Fog::Service::NotFound)

might be related to, they get similar errors :
fog/fog-aws#248
fog/fog-google#170
mitchellh/vagrant-aws#505

[jgrammen-agilitypr]

attempted to find an older combination of fog-aws and fog-core where the issue would not be present.
Was unsuccessful because old version combinations gave me other errors.

Simplest test case below:

#!/usr/bin/env ruby

require 'fog/aws'

ec2 = Fog::Compute.new(
  :provider => 'AWS'
)
puts ec2

ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]

[jgrammen-agilitypr]

with old version:

fog-aws (0.9.3)
fog-core (1.38.0)
fog-json (1.0.2)
fog-xml (0.1.3)

the error is still present

/var/lib/gems/2.3.0/gems/fog-core-1.38.0/lib/fog/core/services_mixin.rb:18:in `rescue in new': aws has no compute service (Fog::Service::NotFound)
        from /var/lib/gems/2.3.0/gems/fog-core-1.38.0/lib/fog/core/services_mixin.rb:8:in `new'
        from /var/lib/gems/2.3.0/gems/fog-core-1.38.0/lib/fog/compute.rb:54:in `new'
        from ./test.rb:5:in `<main>'

This is very confusing, that the error would be present in versions that old

0.9.3 - June 20, 2016 (490 KB)
1.38.0 - April 20, 2016 (45.5 KB)

so after much investigation I have narrowed this issue down to the .fog credentials file
so it seems that as soon as it tries to load credentials from the .fog file, something in the service loading breaks???

It does not appear to be related to fog-core or fog-aws versions

root@test:~# ./test.rb
/var/lib/gems/2.3.0/gems/fog-core-1.45.0/lib/fog/core/services_mixin.rb:18:in `rescue in new': aws has no compute service (Fog::Service::NotFound)
        from /var/lib/gems/2.3.0/gems/fog-core-1.45.0/lib/fog/core/services_mixin.rb:8:in `new'
        from /var/lib/gems/2.3.0/gems/fog-core-1.45.0/lib/fog/compute.rb:54:in `new'
        from ./test.rb:5:in `<main>'
root@test:~# mv .fog .fog.bak
root@test:~# ./test.rb
#<Fog::Compute::AWS::Real:0x00000001b02b00>
root@test:~#

with gem versions:

fog-aws (1.4.1)
fog-core (1.45.0)
fog-json (1.0.2)
fog-xml (0.1.3)

[jgrammen-agilitypr]

finally figured it out.
I had bad yaml in my .fog file

bad config

---
default:
 aws_access_key_id = as
 aws_secret_access_key = ai

good config

---
default:
 aws_access_key_id: as
 aws_secret_access_key: as

the error fog is producing is super un-helpful, as it does not indicate in any way that it failed to parse the .fog yaml file and load credentials.

Sorry to hear about your difficulty, but I'm glad you found a solution. Thanks for your patience and taking the time to explain your solution, hopefully it can help others (and maybe we can figure out ways to improve the errors as well).
