Changes in Apache Libcloud 3.3.1


  • [EC2] Fix a regression introduced in v3.3.0 which would break EC2 driver for some regions because the driver would incorrectly try to use signature version 2 for all the regions whereas some newer regions require signature version 4 to be used.

    If you are unable to upgrade, you can use the following workaround, as long as you only use code which supports / works with authentication signature algorithm version 4:

    import = "4"
    # Instantiate affected driver here...

    Reported by @olegrtecno. (GITHUB-1545, GITHUB-1546)

  • [EC2] Allow user to override which signature algorithm version is used for authentication by passing signature_version keyword argument to the EC2 driver constructor. (GITHUB-1546)


  • [Google Cloud Storage] Fix a bug and make sure we also correctly handle scenario in get_object() method when the object size is returned in x-goog-stored-content-length and not content-length header.

    Reported by Veith Röthlingshöfer - @RunOrVeith. (GITHUB-1544, GITHUB-1547)

  • [Google Cloud Storage] Update get_object() method and ensure object.size attribute is an integer and not a string. This way it’s consistent with list_objects() method. (GITHUB-1547)

Changes in Apache Libcloud 3.3.0


  • Fix a bug which would cause some prepared requests with empty bodies to be chunked which would cause some of the provider APIs such as OpenStack to return HTTP 400 errors. (GITHUB-1487, GITHUB-1488) [Michael Spagon - @mspagon]

  • Optimize various code imports (remove unnecessary imports, make some lazy, etc.), so now importing most of the modules is around ~20-40% faster (~70 vs ~140 ms) and in some cases such as EC2 driver even more.

    Now majority of the import time is spent in importing requests library. (GITHUB-1519) [Tomaz Muraus]

  • libcloud.pricing.get_size_price() function has been updated so it only caches pricing data in memory for the requested drivers.

    This way we avoid caching data in memory for drivers which may never be used.

    If you want to revert to old behavior (cache pricing data for all the drivers in memory), you can do that by passing cache_all=True argument to that function or set libcloud.pricing.CACHE_ALL_PRICING_DATA module level variable to True.

    Passing cache_all=True might come handy in situations where you know the application will work with a lot of different drivers - this way you can avoid multiple disk reads when requesting pricing data for different drivers. (GITHUB-1519) [Tomaz Muraus]

  • Advertise Python 3.9 support in


  • [GCE] Fix ex_set_image_labels method using incorrect API path. (GITHUB-1485) [Poul Petersen - @petersen-poul]

  • [OpenStack] Fix error setting ex_force_XXX_url without setting ex_force_base_url. (GITHUB-1492) [Miguel Caballer - @micafer]

  • [EC2] Update supported EC2 regions and instance sizes and add support for eu-north-1 region. (GITHUB-1486) [Arturo Noha - @r2ronoha]

  • [Ovh] Add support for multiple regions to the driver. User can select a region (location) by passing location argument to the driver constructor (e.g. location=ca). (GITHUB-1494) [Dan Hunsaker - @danhunsaker]

  • [GCE] Add support for creating nodes without a service account associated with them. Now when an empty list is passed for ex_service_accounts argument, VM will be created without service account attached.

    For backward compatibility reasons, default value of None still means to use a default service account. (GITHUB-1497, GITHUB-1495) [David Tomaschik - Matir]

  • [VSphere] Add new VMware VSphere driver which utilizes pyvmomi library and works under Python 3.

    If you want to use this driver, you need to install pyvmomi dependency - pip install pyvmomi (GITHUB-1481) [Eis D. Zaster - @Eis-D-Z]

  • [OpenStack] Enable to get Quota Set detail. (GITHUB-1495) [Miguel Caballer - @micafer]

  • [OpenStack] Add ex_get_size_extra_specs function to OpenStack driver. (GITHUB-1517) [Miguel Caballer - @micafer]

  • [OpenStack] Enable to get Neutron Quota details in OpenStack driver. (GITHUB-1514) [Miguel Caballer - @micafer]

  • [DigitalOcean] _node_node method now ensures image and size attributes are also set correctly and populated on the Node object. (GITHUB-1507, GITHUB-1508) [@sergerdn]

  • [Vultr] Make sure private_ips attribute on the Node object is correctly populated when listing nodes. Also add additional values to the node.extra dictionary. (GITHUB-1506) [@sergerdn]

  • [EC2] Optimize EC2 driver imports and move all the large constant files to separate modules in libcloud/compute/constants/ec2_*.py files.

    Previously all the constants were contained in libcloud/compute/ file. That file was imported when importing EC2 driver which would add unnecessary import time and memory overhead in case this data was not actually used.

    Now most of the large imports are lazy and only happen when that data is needed (aka when list_sizes() method is called).

    libcloud/compute/ file has also been removed. (GITHUB-1519) [Tomaz Muraus - @Kami]

  • [Packet / Equinix Metal] Packet driver has been renamed to Equinix Metal. If your code uses driver, you need to update it as per example in Upgrade Notes documentation section. (GITHUB-1511) [Dimitris Galanis - @dimgal1]

  • [OutScale] Add various extension methods to the driver. For information on available extenion methods, please refer to the driver documentation. (GITHUB-1499) [@tgn-outscale]

  • [Linode] Add support for Linode’s API v4. (GITHUB-1504) [Dimitris Galanis - @dimgal1]


  • Deprecated lockfile library which is used by the Local Storage driver has been replaced with fasteners library. [Tomaz Muraus - @Kami]

  • [S3] Add support for us-gov-east-1 region. (GITHUB-1509, GITHUB-1510) [Andy Spohn - @spohnan]

  • [DigitalOcean Spaces] Add support for sfo2 regon. (GITHUB-1525) [Cristian Rasch - @cristianrasch]

  • [MinIO] Add new driver for MinIO object storage ( (GITHUB-1528, GITHUB-1454) [Tomaz Muraus - @Kami]

  • [S3] Update S3 and other drivers which are based on the S3 one (Google Storage, RGW, MinIO) to correctly throw ContainerAlreadyExistsError if container creation fails because container with this name already exists.

    Previously in such scenario, InvalidContainerNameError exception which does not comply with the Libcloud standard API was thrown. (GITHUB-1528) [Tomaz Muraus - @Kami]

  • Add new libcloud.common.base.ALLOW_PATH_DOUBLE_SLASHES module level variable.

    When this value is set to True (defaults to False for backward compatibility reasons), Libcloud won’t try to sanitize the URL path and remove any double slashes.

    In most cases, this won’t matter and sanitzing double slashes is a safer default, but in some cases such as S3, where double slashes can be a valid path (e.g. /my-bucket//path1/file.txt), this option may come handy.

    When this variable is set to True, behavior is also consistent with Libcloud versions prior to v2.0.0.

    Reported by Jonathan Hanson - @triplepoint. (GITHUB-1529) [Tomaz Muraus - @Kami]


  • [Common] Fix a bug with the header value returned by the export_zone_to_bind_format method containing an invalid timestamp (value for the minute part of the timestamp was wrong and contained month number instead of the minutes value).

    Reported by Kurt Schwehr - @schwehr.

    (GITHUB-1500) [Tomaz Muraus - @Kami]

  • [CloudFlare DNS] Add support for creating SSHFP records. (GITHUB-1512, GITHUB-1513) [Will Hughes - @insertjokehere]

  • [DigitalOcean] Update driver and make sure request data is sent as part of HTTP request body on POST and PUT operations (previously it was sent as part of query params). (GITHUB-1505) [Andrew Starr-Bochicchio - @andrewsomething]

  • [AuroraDNS] Throw correct exception on 403 authorization failed API error. (GITHUB-1521, GITHUB-1522) [Freek Dijkstra - @macfreek]

  • [Linode] Add support for Linode’s API v4. (GITHUB-1504) [Dimitris Galanis - @dimgal1]

  • [CloudFlare] Update driver so it correctly throws RecordAlreadyExists error on various error responses which represent this error. [Tomaz Muraus - @Kami]

Changes in Apache Libcloud 3.2.0


  • libcloud.pricing.download_pricing_file function has been updated so it tries to download latest pricing.json file from our public read-only S3 bucket.

    We now run a daily job as part of our CI/CD which scrapes provider prices and publishes the latest version of the pricing.json file to that bucket.

    For more information, please see


  • [OpenStack] Add ex_get_network() to the OpenStack driver to make it possible to retrieve a single network by using the ID.

    (GITHUB-1474) [Sander Roosingh - @SanderRoosingh]

  • [OpenStack] Fix pagination in the list_images() method and make sure method returns all the images, even if the result is spread across multiple pages.

    (GITHUB-1467) [Thomas Bechtold - @toabctl]

  • [GCE] Add script for scraping GCE pricing data and improve price addition in _to_node_size method. (GITHUB-1468) [Eis D. Zaster - @Eis-D-Z]

  • [AWS EC2] Update script for scraping AWS EC2 pricing and update EC2 pricing data. (GITHUB-1469) [Eis D. Zaster - @Eis-D-Z]

  • [Deployment] Add new wait_period argument to the deploy_node method and default it to 5 seconds.

    This argument tells Libcloud how long to wait between each poll interval when waiting for a node to come online and have IP address assigned to it.

    Previously this argument was not exposed to the end user and defaulted to 3 seconds which means it would be quite easy to reach rate limits with some providers when spinning up many instances concurrently using the same credentials. [Tomaz Muraus - @Kami]

  • [Azure ARM] Add script for scraping Azure ARM instance pricing data. (GITHUB-1470) [Eis D. Zaster - @Eis-D-Z]

  • Update deploy_node() method to try to re-connect to the server if we receive “SSH connection not active” error when trying to run a deployment step.

    In some scenarios, connection may get closed by the server for whatever reason before finishing all the deployment steps and in this case only re-connecting would help and result in a successful outcome. [Tomaz Muraus - @Kami]

  • [Deployment] Make FileDeployment class much faster and more efficient when working with large files or when running multiple FileDeployment steps on a single node.

    This was achieved by implementing two changes on the ParamikoSSHClient class:

    1. put() method now tries to re-use the existing open SFTP connection if one already exists instead of re-creating a new one for each put() call.

    2. New putfo() method has been added to the ParamikoSSHClient class which utilizes the underlying sftp.putfo() method.

      This method doesn’t need to buffer the whole file content in memory and also supports pipelining which makes uploads much faster and more efficient for larger files.

    [Tomaz Muraus - @Kami]

  • [Deployment] Add __repr__() and __str__() methods to all the Deployment classes. [Tomaz Muraus - @Kami]

  • [Deployment] New keep_alive and use_compression arguments have been added to the ParamikoSSHClient class constructor.

    Right now those are not exposed yet to the deploy_node() method. [Tomaz Muraus - @Kami]

  • [Deployment] Update ParamikoSSHClient.put() method so it returns a correct path when commands are being executed on a Windows machine.

    Also update related deployment classes so they correctly handle situation when we are executing commands on a Windows server. [Arthur Kamalov, Tomaz Muraus]

  • [Outscale] Add a new driver for the Outscale provider. Existing Outscale driver utilizes the EC2 compatible API and this one utilizes native Outscale API. (GITHUB-1476) [Tio Gobin - @tgn-outscale]

  • [KubeVirt] Add new methods for managing services which allows users to expose ports for the VMs (ex_list_services, ex_create_service, ex_delete_service). (GITHUB-1478) [Eis D. Zaster - @Eis-D-Z]


  • [LXD] Add new methods for managing network and storage pool capabilities and include other improvements in some of the existing methods. (GITHUB-1477) [Eis D. Zaster - @Eis-D-Z]

Changes in Apache Libcloud 3.1.0


  • [GCE] Add latest Ubuntu image families (Ubuntu 20.04) to the driver.

    (GITHUB-1449) [Christopher Lambert - @XN137]

  • [DigitalOcean] Add location argument to the list_sizes() method.

    NOTE: Location filtering is performed on the client. (GITHUB-1455, GITHUB-1456) [RobertH1993]

  • Fix deploy_node() so an exception is not thrown if any of the output (stdout / stderr) produced by the deployment script contains a non-valid utf-8 character.

    Previously, user would see an error similar to “Failed after 3 tries: ‘utf-8’ codec can’t decode byte 0xc0 in position 37: invalid start byte”.

    And now we simply ignore byte sequences which we can’t decode and include rest of the output which can be decoded.

    (GITHUB-1459) [Tomaz Muraus - @Kami]

  • Add new timeout argument to ScriptDeployment and ScriptFileDeployment class constructor.

    With this argument, user can specify an optional run timeout for that deployment step run. (GITHUB-1445) [Tomaz Muraus - @Kami]

  • [GiG G8] Fix retry functionality when creating port forwards and add support for automatically refresing the JWT auth token inside the connection class if it’s about to expire in 60 seconds or less. (GITHUB-1465) [Jo De Boeck - @grimpy]

  • [Azure ARM] Update create_node so an exception is thrown if user passes ex_use_managed_disks=False, but doesn’t provide a value for the ex_storage_account argument. (GITHUB-1448) [@antoinebourayne]


  • [AWS S3] Make sure driver works correctly for objects with ~ in the name.

    Now when sanitizing the object name, we don’t url encode ~ character.

    Reported by Michael Militzer - @mmilitzer. (GITHUB-1452, GITHUB-1457) [Tomaz Muraus]


  • [CloudFlare] Update driver to include the whole error chain the thrown exception message field.

    This makes various issues easier to debug since the whole error context is included. [Tomaz Muraus]

  • [Gandi Live, CloudFlare, GCE] Add support for managing CAA record types.

    When creating a CAA record, data field needs to be in the following format:

    <flags> <tag> <domain name>

    For example:

    • 0 issue
    • 0 issuewild
    • 0 iodef

    (GITHUB-1463, GITHUB-1464) [Tomaz Muraus]

  • [Gandi Live] Don’t throw if extra['rrset_ttl'] argument is not passed to the create_record method. (GITHUB-1463) [Tomaz Muraus]


  • Update contrib/Dockerfile which can be used for running tests so it only run tests with Python versions we support. This means dropping support for Python < 3.5 and adding support for Python 3.7 and 3.8.

    Also update it to use a more recent Ubuntu version (18.04) and Python 3 for running tox target. (GITHUB-1451) [Tomaz Muraus - @Kami, HuiFeng Tang - @99Kies]

Changes in Apache Libcloud 3.0.0


  • Make sure auth_user_info variable on the OpenStack identify connection class is populated when using auth version 3.x_password and 3.x_oidc_access_token.

    (GITHUB-1436) [@lln-ijinus, Tomaz Muraus)

  • [OpenStack] Update OpenStack identity driver so a custom project can be selected using domain_name keyword argument containing a project id.

    Previously this argument value could only contain a project name, now the value will be checked against project name and id.

    (GITHUB-1439) [Miguel Caballer - @micafer]


  • [GCE] Update create_node() method so it throws an exception if node location can’t be inferred and location is not specified by the user ( either by passing datacenter constructor argument or by passing location argument to the method).

    Reported by Kevin K. - @kbknapp. (GITHUB-1443) [Tomaz Muraus]

  • [GCE] Update ex_get_disktype method so it works if zone argument is not set. (GITHUB-1443) [Tomaz Muraus]

  • [GiG G8] Add new driver for GiG G8 provider ( (GITHUB-1437) [Jo De Boeck - @grimpy]

  • Add new at_exit_func argument to deploy_node() method. With this argument user can specify which function will be called before exiting with the created node in question if the deploy process has been canceled after the node has been created, but before the method has fully finished.

    This comes handy since it simplifies various cleanup scenarios. (GITHUB-1445) [Tomaz Muraus - @Kami]

  • [OpenStack] Fix auto assignment of volume device when using device name auto in the attach_volume method. (GITHUB-1444) [Joshua Hesketh - @jhesketh]

  • [Kamatera] Add new driver for Kamatera provider ( (GITHUB-1442) [Ori Hoch - @OriHoch]


  • Add new download_object_range and download_object_range_as_stream methods for downloading part of the object content (aka range downloads) to the base storage API.

    Currently those methods are implemented for the local storage Azure Blobs, CloudFiles, S3 and any other provider driver which is based on the S3 one (such as Google Storage and DigitalOcean Spaces). (GITHUB-1431) [Tomaz Muraus]

  • Add type annotations for the base storage API. (GITHUB-1410) [Clemens Wolff - @c-w]

  • [Google Storage] Update the driver so it supports service account HMAC credentials.

    There was a bug in the code where we used the user id length check to determine the account type and that code check didn’t take service account HMAC credentials (which contain a longer string) into account.

    Reported by Patrick Mézard - pmezard. (GITHUB-1437, GITHUB-1440) [Yoan Tournade - @MonsieurV]


  • Add type annotations for the base DNS API. (GITHUB-1434) [Tomaz Muraus]


  • [Kubernetes] Add support for the client certificate and static token based authentication to the driver. (GITHUB-1421) [Tomaz Muraus]
  • Add type annotations for the base container API. (GITHUB-1435) [Tomaz Muraus]

Changes in Apache Libcloud v2.8.3


  • Fix deploy_node() so an exception is not thrown if any of the output (stdout / stderr) produced by the deployment script contains a non-valid utf-8 character.

    Previously, user would see an error similar to “Failed after 3 tries: ‘utf-8’ codec can’t decode byte 0xc0 in position 37: invalid start byte”.

    And now we simply ignore byte sequences which we can’t decode and include rest of the output which can be decoded.

    (GITHUB-1459) [Tomaz Muraus - @Kami]


  • [AWS S3] Make sure driver works correctly for objects with ~ in the name.

    Now when sanitizing the object name, we don’t url encode ~ character.

    Reported by Michael Militzer - @mmilitzer. (GITHUB-1452, GITHUB-1457) [Tomaz Muraus]

Changes in Apache Libcloud v2.8.2


  • Add support for Ed25519 private keys for deploy_node() functionality when using paramiko >= 2.2.0. (GITHUB-1445) [Tomaz Muraus - @Kami]

  • Fix deploy_node() so it correctly propagates an exception is a private key which is used is password protected, but no password is specified.

    Previously it incorrectly tried to retry on such exception. This means the exception would only bubble up after all the retry attempts have been exhausted. (GITHUB-1445) [Tomaz Muraus - @Kami]

  • Allow user to specify password for encrypted keys by passing ssh_key_password argument to the deploy_node() method.

    Previously they (GITHUB-1445) [Tomaz Muraus - @Kami]

  • Fix deploy_node() so it correctly propagates an exception if invalid or unsupported private key is used.

    Previously it incorrectly tried to retry on such exception. This means the exception would only bubble up after all the retry attempts have been exhausted. (GITHUB-1445) [Tomaz Muraus - @Kami]

  • Fix deploy_node() method so we don’t retry on fatal SSHCommandTimeoutError exception (exception which is thrown when a command which is running on remote host times out). (GITHUB-1445) [Tomaz Muraus - @Kami]

  • Add new timeout argument to ScriptDeployment and ScriptFileDeployment class constructor.

    With this argument, user can specify an optional run timeout for that deployment step run. (GITHUB-1445) [Tomaz Muraus - @Kami]

  • Add new stdout and stderr attribute to SSHCommandTimeoutError class.

    Those attributes contain value of stdout and stderr produced so far. (GITHUB-1445) [Tomaz Muraus - @Kami]

  • [OpenStack] Fix auto assignment of volume device when using device name auto in the attach_volume method. (GITHUB-1444) [Joshua Hesketh - @jhesketh]

Changes in Apache Libcloud v2.8.1


  • Fix LIBCLOUD_DEBUG_PRETTY_PRINT_RESPONSE functionality and make sure it works correctly under Python 3 when function returns unicode and not bytes.

    (GITHUB-1430) [Tomaz Muraus]


  • [GCE] Fix list_nodes() method so it correctly handles pagination and returns all the nodes if there are more than 500 nodes available in total.

    Previously, only first 500 nodes were returned.

    Reported by @TheSushiChef. (GITHUB-1409, GITHUB-1360) [Tomaz Muraus]

  • Fix some incorrect type annotations in the base compute API.

    Reported by @dpeschman. (GITHUB-1413) [Tomaz Muraus]

  • [OpenStack] Fix error with getting node id in _to_floating_ip method when region is not called nova. (GITHUB-1411, GITHUB-1412) [Miguel Caballer - @micafer]

  • [EC2] Fix ex_userdata keyword argument in the create_node() method being ignored / not working correctly.

    NOTE: This regression has been inadvertently introduced in v2.8.0. (GITHUB-1426) [Dan Chaffelson - @Chaffelson]

  • [EC2] Update create_volume method to automatically select first available availability zone if one is not explicitly provided via location argument. [Tomaz Muraus]


  • [AWS S3] Fix upload object code so uploaded data MD5 checksum check is not performed at the end of the upload when AWS KMS server side encryption is used.

    If AWS KMS server side object encryption is used, ETag header value in the response doesn’t contain data MD5 digest so we can’t perform a checksum check.

    Reported by Jonathan Harden - @jfharden. (GITHUB-1401, GITHUB-1406) [Tomaz Muraus - @Kami]

  • [Google Storage] Fix a bug when uploading an object would fail and result in 401 “invalid signature” error when object mime type contained mixed casing and when S3 Interoperability authentication method was used.

    Reported by Will Abson - wabson. (GITHUB-1417, GITHUB-1418) [Tomaz Muraus]

  • Fix upload_object_via_stream method so “Illegal seek” errors which can arise when calculating iterator content hash are ignored. Those errors likely indicate that the underlying file handle / iterator is a pipe which doesn’t support seek and that the error is not fatal and we should still proceed.

    Reported by Per Buer - @perbu.

    (GITHUB-1424, GITHUB-1427) [Tomaz Muraus]


  • [Gandi Live] Update the driver and make sure it matches the latest service / API updates. (GITHUB-1416) [Ryan Lee - @zepheiryan]

  • [CloudFlare] Fix export_zone_to_bind_format method.

    Previously it threw an exception, because record.extra dictionary didn’t contain priority key.

    Reported by James Montgomery - @gh-jamesmontgomery. (GITHUB-1428, GITHUB-1429) [Tomaz Muraus]

Changes in Apache Libcloud v2.8.0


  • Fix a regression with get_driver() method not working if provider argument value was a string (e.g. using get_driver('openstack') instead of get_driver(Provider.OPENSTACK)).

    Only officially supported and recommended approach still is to use Provider.FOO enum type constant, but since the string notation was unofficially supported in the past, we will still support it until the next major release.

    Reported by @dpeschman. (GITHUB-1391, GITHUB-1390) [Tomaz Muraus]

  • Include py.typed data file to signal that this package contains type annotations / hints.

    NOTE: At the moment, type annotations are only available for the base compute API. [Tomaz Muraus]

  • Fix universal wheel METADATA and ensure conditional dependencies (backports.ssl_match_hostname, typing, enum34) are handled correctly.

    Reported by Adam Terrey (@arterrey). (GITHUB-1392, GITHUB-1393) [Tomaz Muraus]


  • [DigitalOcean] Fix attach_volume and detach_volume methods. Previously those two methods incorrectly passed volume id instead of volume name to the API. (GITHUB-1380) [@mpempekos]

  • [GCE] Add ex_disk_size argument to the create_node method. (GITHUB-1386, GITHUB-1388) [Peter Yu - @yukw777]

  • [VMware vCloud] Various improvements, fixes and additions to the driver. (GITHUB-1373) [OpenText Corporation]

  • Update deploy_node() method so it now only passes non-deploy node keyword arguments + auth argument to the underlying create_node() method. Previously it also passed deploy_node() specific arguments such as deploy, ssh_username, max_tries, etc. to it.

    Because of that, a lot of the compute drivers which support deploy functionality needed to use **kwargs in create_node() method signature which made code hard to read and error prone.

    Also update various affected drivers to explicitly declare supported arguments in the create_node() method signature (Dummy, Abiquo, Joyent, Bluebox, OpenStack, Gandy, VCL, vCloud, CloudStack, GoGrid HostVirtual, CloudSigma, ElasticStack, RimuHosting, SoftLayer, Voxel, Vpsnet, KTUcloud, BrightBox, ECP, OpenNebula, UPcloud).

    As part of this change, also various issues with invalid argument names were identified and fixed. (GITHUB-1389) [Tomaz Muraus]

  • Add MyPy type annotations for create_node() and deploy_node() method. (GITHUB-1389) [Tomaz Muraus]

  • [GCE] Update deploy_node() method so it complies with the base compute API and accepts deploy argument.

    This method now also takes all the same keyword arguments which original create_node() takes. (GITHUB-1387) [Peter Yu - @yukw777, Tomaz Muraus]

  • [Common] To make debugging and troubleshooting easier, add __repr__ and __str__ method to the ScriptDeployment class. [Tomaz Muraus]

  • [Common] Add type annotations / hints for rest of the base compute API classes and methods. [Tomaz Muraus]


  • [AWS S3] Make sure host driver constructor argument has priority over region argument.

    This means if you specify host and region argument, host won’t be inferred from the region, but host argument will be used for the actual connection host value. (GITHUB-1384, GITHUB-1383) [@gluap]

Changes in Apache Libcloud v2.7.0


  • Test code with Python 3.8 and advertise that we also support Python 3.8. (GITHUB-1371, GITHUB-1374) [Tomaz Muraus]


  • [OpenStack] Fix OpenStack project scoped token authentication. The driver constructors now accept ex_tenant_domain_id argument which tells authentication service which domain id to use for the scoped authentication token. (GITHUB-1367) [kshtsk]


  • Introduce type annotations for the base compute API methods. This means you can now leverage mypy to type check (with some limitations) your code which utilizes Libcloud compute API standard API methods.

    Keep in mind that at this point, type annotations are only available for standard compute API methods. (GITHUB-1306) [Tomaz Muraus]

  • [Azure ARM] Fix attach_volume method and allow maximum of 64 disks to be added when LUN is not specified. Previously there was a bug and only a maximum of 63 disks could be added. (GITHUB-1372) [Palash Gandhi - @palashgandhi]

  • New start_node and stop_node methods have been added to the base Libcloud compute API NodeDriver class.

    A lot of the existing compute drivers already implemented that functionality via extension methods (ex_start_node, ex_stop_node) so it was decided to promote those methods to be part of the standard Libcloud compute API and update all the affected drivers.

    For backward compatibility reasons, existing ex_start and ex_stop_node methods will still work until a next major release.

    (GITHUB-1375, GITHUB-1364) [Tomaz Muraus, @emakarov]

  • [GCE] Add new ex_set_volume_labels method for managing volume labels to the driver. (GITHUB-1376) [Rob Zimmerman - @zimventures]
  • [EC2] Add support for new inf1.* instance types. [Tomaz Muraus]


  • [S3] Update S3 driver so a single driver class can be used for different regions.

    Region which is used is controled by the region driver constructor argument.

    Previously, that driver followed “driver class per region” approach. That approach will be deprecated and removed in a future release.

    For more information, please refer to the Upgrade Notes documentation section. (GITHUB-1371) [Tomaz Muras]

  • [S3] Add missing eu-north-1 region to the S3 driver. (GITHUB-1370) [michaelsembwever]

  • [S3] Add missing regions (eu-west-3, ap-northeast-3, me-south-1) to the driver. (GITHUB-1371) [Tomaz Muras]
