Recently I was having issues with the Openstack api not being available due to network issues at our hosting provider. The default timeout is 60 seconds with 3 retries which would hang my Sidekiq process for 3 minutes.

Would you be open to a PR which lets you set the http timeout as an option?

There is no method of specifying an SSL protocol to use, or of passing a CA file.

As reported by Christian Karnath in Apache JIRA:

These issues were revealed by testing the Openstack 1.0.3 gem with Deltacloud - quoting Christian here:

I'm very very sorry, but I still found some new issues after excessive testing deltacloud with openstack-rubygem 1.0.3 against openstack essex, diablo and cactus. :-( I dont't know if this is the correct thread or if we should open new cases for the following issues:

• When requesting a single instance against essex the id-field is empty right now (when requesting all instances the id-fields are filled).
• When requesting a single instance against diablo the id-field is a guid-string instead of an integer (requesting all instances will return integer ids). When requesting a single image against diablo the name-field is null (requesting all images will fill the name field correctly).
• When requsting all instances (or images) against cactus the following stack trace occurs:

Hi, would you mind to tag each release? Thank you.

Thanks!

Hi, I'm pretty new to OpenStack but I would like to add a piece of information into the Wiki Authentication page regarding the Other parameters for the create method: section.
Something like that:

• :region - (Optional for v2.0 auth only). The specific service region to use. Defaults to first returned region.

Or maybe something like this:

• Please see the full list of available options in the ruby doc

How should I proceed to contribute and what do you think about these changes?
Great gem BTW!

François

Hi all,

is there any way, with your api implementation to get a list of servers from all tenants, like passing the "--all-tenants" flag to # nova list ? or maybe to have a tenant list in order to iterate through it to have all servers ?
Thanx a lot !

Cheers

When I use vcr/webmock with ruby-openstack, I get an exception where webmock ends up calling ChunkedConnectionWrapper.read with 0 arguments (and ChunkedConnectionWrapper.read requires at least 1 argument).

As I trace the code, I see ChunkedConnectionWrapper.read defers to StringIO.read which accepts 0 arguments!

It seems, then, ChunkedConnectionWrapper.read should have method signature:
def read(length=nil, buffer=nil) instead of def read(length, buffer=nil)

Does this make sense?

I'm not sure where to report this: when using the create_object container method, I get the above error

container.create_object(content.name, {:metadata=>content.meta, :content_type=>content.mime_type}, File.open(cf, 'rb') {|file| file.read })

If I leave out the reading of the file, the object is created with 0 bytes

    container.create_object(content.name, {:metadata=>content.meta, :content_type=>content.mime_type})

stack trace:

Hi, I'm trying to connect to a Openstack (Devstack) server with the line:
os = OpenStack::Connection.create({
:username => "admin",
:auth_method => 'password',
:api_key => "supersecret",
:auth_url => "http://192.168.52.162/" })

And I got

URI::InvalidURIError: bad URI(is not URI?):
from /usr/lib/ruby/1.9.1/uri/common.rb:176:in 'split'

'

I think that is coming from the fact that there's no 'x-server-management-url' in the server http response and so the line:

uri = URI.parse(response["x-server-management-url"])
send an uri error but I don't know how to fix it.

During debugging my issue I notice that when create a connection OpenStack::Connection.create(connection4) it always send a GET request, I did more debugging and I found that it detects my auth_url as version 1. There is an issue in the regex in init method Line329

My auth_url is https://api.example.com/identity/v3/auth/tokens

Suggested regex

def self.init(conn)
  if conn.auth_path.match? /(v3)+\d{0,2}/
    AuthV30.new(conn)
  elsif conn.auth_path.match? /(v2)+\d{0,2}/
    AuthV20.new(conn)
  else
    AuthV10.new(conn)
  end
end

If you consider this a valid issue, I can PR this as a fix

I want to upload objects to Swift container. Currently object.write("penguins have knees") will return true without update of the object in Swift. The response from Swift API is following: <Net::HTTPCreated 201 Created readbody=true>.

My first guess is that this happens because of Content-Length is left to be 0 inside this code.

After I passed String object to OpenStack::Connection#put_object as a data everything worked.

I can't associate securitygroups :

newserver = os.create_server(:name => "toto" :security_groups => "default", :imageRef => image.id, :flavorRef => flavor.id)

The same with something different than default.

The OpenStack Volume Connection #create_volume method doesn't explicitly say what the options are that should be in the options hash. Is there anywhere where that options hash for volumes would be listed out?

First of all, thanks for this awesome project. I'm moving from S3 to Openstack/Swift and this seems the gem to go for handling Swift objects in my Rails app.

My question is, because I can't find it in the code nor the readme, does this gem support Temporary URL middleware, as described here: http://docs.openstack.org/developer/swift/api/temporary_url_middleware.html ?

Supporting OpenStack heat would allow creation of whole stacks using ruby-openstack.

Running test suite, I got following error:

Any idea what the problem is here? in auth_url, I've specified "https://my.url:5000/v2.0/

I'd love to be able to create users and projects -- and associations between the two -- via this gem. It could help with some of the scripting, etc., I'm trying to make happen.

We are using ruby-openstack gem to store binary files in swift openstack object storage. We have discovered that there is an inconsistency in headers structure that is used in write vs create_object methods.
In StorageObject class create_object method expects headers to be in the following form:
{ etag: 'some_value',
content_type: 'application/x-tar',
metadata: { 'X-Object-Meta-project'=>'MyContainer',
'X-Object-Meta-project_id'=>'testABC',
...}
}
this method is used when depositing new object into object storage.
However, when we updating existing object, we use write method and headers hash structure key/value pairs are expected to be all strings, so we are passing something like this:

{'etag'=>'22affe973e2175a72a11c9ecb1acc664',
'content-type'=>'application/x-tar',
'X-Object-Meta-project'=>'MyContainer',
'X-Object-Meta-project_id'=>'testABC',
....}
this is works great but it is confusing and we think it should be consistent.

There are two inconsistencies here:

1. in one case symbols are used as keys in hash, in other case strings
2. for write method hash has flat structure, for create_object method one element of the hash has to be another metadata: hash (as in example above)

If i have a container in swift, wich contain more than 10000 objects, than i can't get full list with cont.objects_detail or cont.objects.

So, please, implement support of getting long lists of objects in Swift.

Hi!

Since the release of Openstack Havana the preferred version of Identity to use is v3. Some cloud providers have now migrated to only supporting v3 for token generation to get support for domains.

Currently Ruby OpenStack does not work with providers that require support for Identity v3.

Would it be possible to add support for Identity v3 in this project as well?

So I tested ruby(1.8.7 1.9.3) is OK , But 2.0.0.2.1.2 show that error message , Is there any update for ruby-openstack about new ruby version(2.0.0+) recently ?
Thanks all .

This commit: 44a421f

Deletes lib/version.rb which defined OpenStack::VERSION.

This is needed to set the user-agent header in connection.rb:228: https://github.com/ruby-openstack/ruby-openstack/blob/master/lib/openstack/connection.rb#L228

It looks like this commit changes the way versioning is defined, so I don' want to just add the file back in.

I started implementing it, wanted to make sure I'm not duplicating effort. Also, I am a little confused as to how you are handling the versions of APIs for things (are you assuming that an endpoint returns the version to use, are you handling all of the possibilities of each version?)

I can set the user-metadata, but I cannot see how to set ACLs (read, write) with this client.

It would be great to support that...something like:

# getting
container.read_acl

#setting
container.read_acl = (foo)

# getting
container.write_acl

# setting
container.write_acl = (foo)

See the dev API docs for details: http://developer.openstack.org/api-ref-objectstorage-v1.html

Also, any particular reason OpenStack::VERSION stopped being used instead of hardcoding versions at gemspec?

Version 1.1.2 still installs just fine, although 1.2.0 doesn’t even exist in RubyGems listing.

if response.body.nil? && response.code == "404" #HEAD ops no body returned
exception_class = self.const_get("ItemNotFound")
raise exception_class.new("The resource could not be found", "404", "")

because the response.body is not nil, so it will not raise ItemNotFound

so in the method of delete_object, can not catch the exception
