Hi Chip,
fun ! The fact that you don't have a provider at the point where you
print it, isn't an issue; what you pass into Deltacloud::new (defined on
line 127 in lib/deltacloud/api.rb) is an options hash, which contains
user/password for credentials, but also the provider.
The provider does not wind up in the credentials, but in
Thread.current[:provider], which you should access within your driver by
calling api_provider (lib/deltacloud/drivers/base_driver.rb:278)
It seems this needs slightly better docs :(
Also, to keep credentials and the like out of the code that will get
checked in, you should create a file ${HOME}/.deltacloud/config and put
the following in it (it's a YAML file):
cloudstack:
user: USERNAME
password: PASSWORD
provider: SOME_URL
mock:
user: mockuser
password: mockpassword
provider: compute
(you can put more credentials in there for ec2 etc.)
In your test, load the credentials for your driver with
Deltacloud::Test::config.credentials("cloudstack")
(tests/test_helper.rb:81) - actually, I see it doesn't pull out the
provider from the config file; it would actually be a good idea to add a
method driver to Deltacloud::Test::Config:
def driver(name)
params = @hash[name.to_s]
raise "No config for driver #{name}" unless params
Deltacloud::new(name, params)
end
so that you can just say 'driver =
Deltacloud::Test::config.driver(:cloudstack)' in your tests and get a
driver that is setup according to your ~/.deltacloud/config.
