v0.16¶

Released: Tue Nov 11 10:44:57 EET 2014

Synnefo-wide¶

Replace accumulative projects with pool projects:
- Projects are now viewed as a source of finite resources. A member can reserve a part of these resources up to a specified limit.
- Base quota are now offered through a special purpose user-specific system project, identified with the same UUID as the user.
- Each actual resource (Cyclades VM, network, floating IP and Pithos container) is now also associated with a project besides the owner.
- In resource creation, project defaults to the user-specific system project, if not specified otherwise. It is also possible to change the project assignment of an existing resource.
- All existing resources have been assigned to the respective user-specific system projects.
Logging mechanism for Synnefo management commands
- Log all stdout and stderr output of every invocation of snf-manage, on unique filenames under a given directory.
- Add a new setting in the snf-common package, namely ‘LOG_DIR’, which specifies the directory to be used by Synnefo components to write their log files.
Rename argument names of Synnefo management commands
- All Synnefo management commands now use ‘user/flavor/image/network’ as argument names, instead of ‘userid/user-id/owner/flavor-id/image -id/network-id’, for consistency across commands.

Astakos¶

Decouple projects from applications:
- Support project creation (by the system) and modification (by a privileged user) without the need to submit/approve an application.
- View applications as modifications. When a project is uninitialized (e.g. an application for a new project is pending), no further modification is allowed.
- Applications are removed from the API. A project’s last application is only accessible as part of the project details.
- Decouple project state from application state; they can be combined by an API client, if needed.
Changes concerning quota and pool projects:
- A project must provide limits for all registered resources. On project activation, resources missing are automatically completed using a skeleton.
- Field ‘uplimit’ of registed resources is exposed as ‘system_default’ and provide the skeleton for user-specific system projects. A new field ‘project_default’ is introduced to act as a skeleton for conventional projects.
- The quotaholder now also records project quota besides user quota. The two types of holders are distinguished with a prefix: ‘user:’ and ‘project:’.
- The quota API is extended to make project quota available.
- Removed setting ‘ASTAKOS_PROJECTS_VISIBLE’; we now always display projects in the Astakos menu.
Projects can be set ‘private’, making it accessible only to its owner and members.
Admin users API
- Extend astakos identity API to support user management functionality.
- Admin API related settings
- ADMIN_API_ENABLED Whether or not the admin api endpoints will be enabled.
- ADMIN_API_PERMITTED_GROUPS A list of group names for which users which belong to any of them be granted full access to the admin API endpoints.
Updated projects integration in UI

Display both max per member/total in group quota in project views.

Enhanced usage view to display individual resource usage details for each of the projects the user is associated with.

  - CYCLADES_SNAPSHOTS_ENABLED: Enable/Disable the snapshots feature altogether at the API level.
Integrate Cyclades resources with Astakos projects.
- Extend API calls that create resources with the ‘project’ attribute in order to assign resources to the specified project.
- Implement API calls for reassigning resources to a new project.
- Export the project that a resource belongs in the ‘tenant_id’ API attribute.
Add support for snf-vncauthproxy 1.6 (configurable VNC console types).
Change the CYCLADES_VNCAUTHPROXY_OPTS setting to a list of dictionaries and support configurable vncauthproxy proxy addresses (added in snf-vncauthproxy-1.6).
Add support for more types of VM console:

- Add support for the three OpenStack Compute console actions (VNC, RDP, Spice). RDP and Spice are currently not implemented.
Update Cyclades to work with Pithos with integrated Archipelago v2 mapfiles.
Include functionality for checking the status of the Cyclades update path, which includes Ganeti, AMQP, snf-ganeti-eventd and snf-dispatcher. This functionality is implemented as part of the snf-dispatcher and can be used by passing the ‘–status-check’ option.
Add setting CYCLADES_VM_MAX_METADATA to limit the maximum number of metadata per vm.
Add setting CYCLADES_VOLUME_MAX_METADATA to limit the maximum number of metadata per volume.
Use common -u/–user option to specify the UUID or email of the user, for all management commands.
Store basic information about images that have been used to create servers, in order to preserve this information even if images are deleted from Pithos.
Make ‘snf-ganeti-eventd’ tolerate failures when processing Ganeti jobs. The daemon will not crash but continue to run in order to process jobs that can be processed.
Update ‘backend-list’ command to not count the free IPs from networks that are drained.
Fix the’network-inspect’ command to not contain externally reserved IPs in th number of available IPs.
Add GANETI_DISKS_WAIT_FOR_SYNC setting to decide whether Ganeti will wait for the disk mirror to sync (–no-wait-for-sync Ganeti option).

v0.15¶

Released: Mon Mar 10 14:01:32 EET 2014

Synnefo-wide¶

Integrate Pithos tests in continuous integration.
Change astakosclient to accept AUTH_URL instead of BASE_URL ASTAKOS_BASE_URL settings has been removed from Pithos and Cyclades and has been replaced with ASTAKOS_AUTH_URL. Both Pithos and Cyclades proxy the Astakos services under ASTAKOS_PROXY_PREFIX path. ASTAKOS_PROXY_PREFIX by default has a value of ‘_astakos’. More specifically, Astakos’ identity service is proxied under ‘_astakos/identity’, Astakos’ account service is under ‘_astakos/account’ and Astakos’ ui service is under ‘_astakos/ui’.
Add ‘mail_admins’ handler to ‘django.request’ logger in order to send email notifications to users listed in ‘ADMINS’ setting about unhandled exceptions in the code.
Extend astakosclient to request and validate OAuth 2.0 access tokens
Change response status code from 400 (Bad Request) to 405 (Not allowed method) in case of an unexpected request method.

Astakos¶

Changes in project schema:
- A Project entry is created when submitting an application for a new project, rather than on approval. Its state is dependent on the state of its ‘reference’ application (current definition). Lock Project rather than Chain (the latter is semantically obsolete).
- Project states “Active - Pending” and “Suspended - Pending” have been removed. In management command ‘project-list’, the existence of a pending modification is indicated by a non-blank ‘Pending AppID’.
- Improve recording of project, application, and membership actions.
Implement API calls for projects.
Store the base URL of a component. The deployer should provide it when adding a new component. Service endpoints originating from a component are expected to match its base URL; otherwise, a warning is issued. re-registration with ‘snf-component-register’ affects both the base and the ui URL.
Changes in resource and quota handling:
- New resources are registered with unlimited default base quota, represented by 2**63-1.
- Each newly accepted user copies the default value for all resources as their own base quota. A base quota is considered ‘custom’ if its value differs from the default.
- Changing resource’s default quota affects the base quota only of future users.
- Resource definition got flags ‘api_visible’ and ‘ui_visible’, replacing flag ‘allow_in_projects’. They control whether a user can access these resources. The system internally always accounts for all resources, and a user can get off quota even for a resource that is not visible.
Remove API call GET /account/v1.0/authenticate in favor of POST /identity/v2.0/tokens.
Export basic statistics about Astakos service at the ‘/admin/stats/detail’ API endpoint. Access to this endpoint is only allowed to users that belong to the Astakos groups that are defined in the ‘ASTAKOS_ADMIN_STATS_PERMITTED_GROUPS’ setting. Statistics are also available through the ‘snf-manage stats-astakos’ management command.
Implement OAuth 2.0 Authorization Code Grant Add API calls for authorization code and access token generation
Add API call for validating OAuth 2.0 access tokens
Shibboleth module Extract unique identifier from the REMOTE_USER header.
Automatically fill third-party signup form fields when available by the the third-party provider.
Management commands:
- Introduced new commands:
  - component-show
  - quota-list (replacing quota, supports various filters)
  - quota-verify (replacing quota)
  - oauth2-client-add (register OAuth 2.0 client)
  - oauth2-client-list (list registered oauth 2.0 clients)
  - oauth2-client-remove (remove OAuth 2.0 client)
- Changed commands:
  - component-add got options –base-url and –ui-url
  - resource-modify –limit became –default-quota
  - user-modify can operate on multiple users with –all and –exclude
  - user-modify –set-base-quota became –base-quota
- Removed commands:
  - quota
  - resource-import (subsumed by service-import)
  - resource-export-astakos (subsumed by service-export-astakos)
Fix request authorization code failures due to Unicode issue: https://code.grnet.gr/issues/4971
Omit validation issues for non-required metadata values received from the third-party authentication provider.

Cyclades¶

Major changes to Cyclades networks:
- Implement ‘cyclades_network’ service, containing the /networks, /ports, /subnets and /floatingips API endpoints under ‘/network/v2.0’. The old /networks API of ‘cyclades_compute’ (under /compute/v2.0) is removed.
- Implement ‘snf-manage subnet-{create, list, modify, inspect}’ management commands for handling of subnets.
- Implement ‘snf-manage port-{create, list, remove, inspect}’ management commands for handling of ports.
- Add two new settings, ‘CYCLADES_FORCED_SERVER_NETWORKS’ and ‘CYCLADES_DEFAULT_SERVER_NETWORKS’ to control the networks that newly created servers will be connected.
Implement Floating IP addresses, which are IPv4 addresses that can be dynamically added and removed to a running server.
- Add new ‘cyclades.floating_ip’ resource.
- Implement ‘snf-manage floating-ip-{create,list,remove,attach,detach}’ management commands to handle floating IPs.
- Add ‘floating_ip_pool’ attribute to networks to mark networks that can be used as floating IP pools.
Implement ‘resize’ server action.
- Implement the ‘resize’ server action, to change the flavor of a server. Only ‘cpu’ and ‘memory’ resizing is supported.
Compute quotas for CPU and memory of running VMs.
- Change ‘cyclades.cpu’ and ‘cyclades.ram’ resources to represent the CPU and RAM for running VMs. Total CPU and RAM usage is represented by new ‘cyclades.total_cpu’ and ‘cyclades.total_ram’ resources.
Refer to Ganeti NICs by their name instead of their index.
- Make cyclades give a unique name to each Ganeti NIC. NICs are refered by their unique name and not by their index inside the VM that are connected to.
Support firewall profile for all NICs of an instance. Change firewall settings to be filled with the unique name of the NIC. The affected settings are the GANETI_FIREWALL_{ENABLED, DISABLED, PROTECTED}_TAG settings.
Add accounting for public IP addresses that is accessible via snf-manage ip-list management command and via the helpdesk app.
Implement IPv6 only networks.
Extend servers info API response with ‘SNF:fqdn’ attribute, and introduce CYCLADES_SERVERS_FQDN to set the template for servers FDQN. Remove ‘UI_VM_HOSTNAME_FORMAT’ setting.
Extend servers info API response with ‘SNF:port_forwarding’ attribute, describing port forwarding rules (DNAT) that are applied to vms. The description of such rules is done via the new CYCLADES_PORT_FORWARDING setting.
Speed up server reconciliation, by performing parallel reconciliation for each backend.
Change –dhcp option of network management commands from a flag to a boolean value, e.g. –dhcp=True
Remove ‘ARCHIPELAGO_BACKENDS’ setting used to distinguish between backends that hosted only archipelago backends. Instead allocation is based on which disk-templates are enabled in each backend.
Implement ‘snf-manage server-remove’ management command.
Move reconciliation of IP pools from ‘reconcile-networks’ to ‘reconcile-pools’. The IP pool reconciliation does not reconcile the IP pools with Ganeti. Instead it checks if the pool is consistent with the IPs that are used by instances.
Do not automatically release externally reserved IPs if they are released from a Ganeti backend. Management of externally reserved IPs must be performed from Cyclades with ‘network-modify’ command.
Export basic statistics about Cyclades Service at the ‘/admin/stats/detail’ API endpoint. Access to this endpoint is only allowed to users that belong to the Astakos groups that are defined in the ‘ADMIN_STATS_PERMITTED_GROUPS’ setting. Statistics are also available through the ‘snf-manage stats-cyclades’ management command.
Support enforcing quota through command ‘enforce-resources-cyclades’.
Remove command ‘resource-export-cyclades’ subsumed by ‘service-export-cyclades’.
Obsolete PUBLIC_USE_POOL setting, since Cyclades manages IP pool for all type of networks.
Encrypt / decrypt the instance id / hostname in the stats URL in snf-cyclades-app and snf-stats-app, using the ‘CYCLADES_STATS_SECRET_KEY’ and ‘STATS_SECRET_KEY’ respectively.
Add support for snf-vncauthproxy-1.5 and the setting ‘CYCLADES_VNCAUTHPROXY_OPTS’, which configures the extra options / arguments needed by the newer version of snf-vncauthproxy. Support for older versions of snf-vncauthproxy has been dropped. See also the upgrade notes for Synnefo and snf-vncauthproxy-1.5.
Remove ‘DEFAULT_ROUTING_TABLE’ setting. If a link for an IP_LESS_ROUTED network is not specified, the link will be uniquely named ‘snf-link-$network_id’.

Common synnefo 404/500 templates (located in snf-webproject)

Astakos¶

Redesign of the accounting system (quotaholder) and integration into Astakos.
- Simplified the quotaholder model; removed tables Entity and Policy; now table Holding contains limit and usage for every holding.
- Extended table Holding, so that we can keep track of quota for every valid combination of holder (e.g. user), resource, and source (e.g. the default system or some specific project).
- Refactored code for issuing and resolving commissions for robustness; added a ‘force’ option to bypass the upper limit check when issuing a commission.
- Simplified syncing to the quotaholder; removed fields from models Project and ProjectMembership, previously needed for syncing; removed state PROJECT_DEACTIVATED from ProjectMembership.
- Removed settings ASTAKOS_QUOTAHOLDER_URL, ASTAKOS_QUOTAHOLDER_TOKEN, and ASTAKOS_QUOTAHOLDER_POOLSIZE.
API-related changes:
- Implemented API calls for quota, resources, and commissions.
- Moved all API calls under ‘/account/v1.0’.
- Implemented the keystone API call POST /tokens under ‘/identity/v2.0’.
Service and resource specification and handling:
- Specified a format for defining services along with the API endpoints and the resources they expose. Migrated internal resource name by prefixing it with service name (e.g. ‘vm’ becomes ‘cyclades.vm’); renamed registered service ‘pithos+’ to ‘pithos’.
- Specified a procedure to register a Synnefo component, its services and their resources in astakos and set the resources’ default base quota limit. Removed resource definitions from settings.
- Moved service and resource presentation data out of the respective db models into a separate file of UI constants.
Converted the limit on pending applications from a setting to a quotable resource. Converted the related user setting to a user-specific base quota limit. Deprecated model UserSetting; removed setting ASTAKOS_PENDING_APPLICATION_LIMIT.
Changes in locking strategy:
- Lock only project’s chain for all project operations; lock user before syncing to quotaholder.
- When locking multiple rows (e.g. users or holdings) include an ORDER BY clause in the query to impose ordering on locking.
Changes in views:
- Replaced custom transaction context with a simple decorator for managing transactions and a context ‘ExceptionHandler’, which logs and suppresses exceptions
Added fine grain user auth provider’s policies.
- Administrator can override default auth provider policies to a specific user or group of users.
- Optionally a user can be assigned to a list of groups, based on the authentication method he choosed to signup.
Removed explicit handling of SMTP errors on each email delivery. Exceptions are now propagated to base django exception handler.
Email used in html/email tempaltes which prompt user to contact for service support prompts is now defined in CONTACT_EMAIL setting introduced in snf-common settings.
Improvements in user activation flow
- User moderation now takes place after the user has verified his email address.
- User model enriched with additional user state fields
- Split activation email from moderation process. Administrator is required to moderate user explicitly using the user-modify –accept or user-modify –reject commands.
- Improved logging throught out user activation procedures.
Remove deprecated AstakosUser model fields: provider, third_party_identifier
Allow override of authentication provider messages using the following format in setting names: ASTAKOS_<PROVIDER_MODULE>_<MSGID>_MSG
Cloudbar automatically tries to identify the active service based on window location.
Removing authentication provider view is now CSRF protected.
New API access view, containing useful information to users on how to access available Synnefo services API’s.
Remove of ASTAKOS_*_EMAIL_SUBJECT settings. All email subjects are now defined in astakos.im.messages module. Overriding default values can be achieved using custom gettext files or using astakos messages settings:
```
#change of greeting email subject
ASTAKOS_GREETING_EMAIL_SUBJECT_MESSAGE = 'Welcome to my cloud'
```
Remove ASTAKOS_ACTIVATION_REDIRECT_URL and ASTAKOS_LOGIN_SUCCESS_URL from astakos .conf file. Settings are dynamically computed based on ASTAKOS_BASE_URL.
Management commands:
- Introduced new commands:
  - authpolicy-{add, list, remove, set, show}
  - group-{add, list}
  - component-{add, list, modify, remove}
  - reconcile-resources-astakos
  - resource-{export-astakos, import, modify}
  - service-{export-astakos, import, show}

  - astakos-quota to quota
  - user-update to user-modify
  - full-cleanup to cleanup-full
