Details¶
This release took much more time than we expected, but we have a lot of reasons for such delay and if you look at our change-log, you will understand them.:)
Here is a quick introduction:
- To make our releases as much as possible stable, we added upper limits for each of our requirements;
- A lot of deprecated lines of code were removed, so be careful;
- Statistics trends for given tasks were introduced;
- Support for tempest plugins was added;
- Several new pages at docs.
Specs & Feature Requests¶
Logging¶
- disable urllib3 warnings only if the library provide them
Database¶
[doesn't require migration] Transform DB layer to return dicts, not SQLAlchemy models
Rally Deployment¶
Support single-AZ deployment
This supports the case where OpenStack is deployed with a single AZ for both controller(s) and compute(s), and not all hosts in the AZ that contains an instance are guaranteed to have the nova-compute service.
Extend creation from environment with several new vars
- OS_ENDPOINT_TYPE/OS_INTERFACE
- OS_USER_DOMAIN_NAME
- OS_PROJECT_DOMAIN_NAME
Improve devstack plugin for Keystone V3
Rally Task¶
NEW!! Statistics trends for given tasks.
Rally Verify¶
Remove '--tempest-config' arg from 'reinstall' command
Warning
Using --tempest-config is became an error from this release. Use rally verify genconfig cmd for all config related stuff.
Don't install Tempest when rally verify start
Warning
Use should use rally verify install cmd to install tempest now
Add ability to setup version of Tempest to install
Configure 'aodh' service in 'service_available' section
Check existence of Tempest-tree in rally verify discover cmd
Make Tempest work with auth url which doesn't include keystone version
Tempest needs /v2.0 and /v3 at the end of URLs. Actually, we can't fix Tempest, so we extend our configuration module with workaround which allow to specify auth_url without version in rally deployment config.
Use default list of plugins for sahara
Move tempest related options of rally configuration to separate section.
NEW!! Support for tempest plugins.
Plugins¶
In this release we are happy to introduce new entity - plugins Base classes
We have a lot of base plugin entities: Context, Scenario, SLA and etc. Sometimes plugins of different bases can have equal names(i.e ceilometer OSClient and ceilometer Context). It is normal and we should allow such conflicts. To support such cases we introduced new entity - plugin base. Statements of plugin bases:
- Each plugin base is unique entity;
- Names of plugin bases can't conflict with each other;
- Names of two or more plugins in one plugin base can't conflict with each other(in case of same namespace).
- Names of two or more plugins in different plugin base can conflict
- Current list of plugin bases:
- rally.task.context.Context
- rally.task.scenario.Scenario
- rally.task.types.ResourceType
- rally.task.exporter.TaskExporter
- rally.task.processing.charts.Chart
- rally.task.runner.ScenarioRunner
- rally.task.sla.SLA
- rally.deployment.serverprovider.provider.ProviderFactory
- rally.deployment.engine.Engine
- rally.osclients.OSClient
OSClients
- NEW!! Support for Senlin client
- NEW!! Support for Gnocchi client
- NEW!! Support for Magnum client
- NEW!! Support for Watcher client
- Transmit endpoint_type to saharaclient
Scenarios:
- NEW!!:
[Sahara] Add configs to MapR plugin
Extend CinderVolumes.create_and_upload_volume_to_image with "image" argument
Deprecate Dummy.dummy_with_scenario_output scenario in favor of Dummy.dummy_output
Warning
Dummy.dummy_with_scenario_output scenario will be removed after several releases
Extend CinderVolumes.create_volume_and_clone with nested_level
Add nested_level argument for nested cloning volume to new volume
Extend CinderVolumes.create_nested_snapshots_and_attach_volume
Two new arguments were added: create_volume_kwargs and create_snapshot_kwargs
Warning
All arguments related to snapshot creation should be transmitted only via create_snapshot_kwargs.
Introduce new style of scenarios - class based.
Improve report for VMTasks.boot_runcommand_delete
[Sahara] Added 5.5.0 version for cdh-plugin and 1.6.0 version for spark
Extend boot_server_from_volume_and_delete, boot_server_from_volume, boot_server_from_volume_and_live_migrate, boot_server_from_volume_snapshot scenarios of NovaServers class with "volume_type" parameter.
Contexts:
NEW!!:
Use Broker Pattern in Keystone roles context
Use immutable types for locking context configuration
Since context configuration passed to Context.__init__() was a mutable type (dict or list), sometimes we had unexpected changes done by unpredictable code (for example, in wrappers).
Add possibility to balance usage of users
For the moment all users for tasks were taken randomly and there was no way to balance them between tasks. It may be very useful when we have difference between first usage of tenant/user and all consecutive. In this case we get different load results.
Therefore, "users" context was extended with new config option 'user_choice_method' that defines approach for picking up users.
Two values are available: - random - round_robin
Default one is compatible with old approach - "random".
Make sahara_image and custom_image contexts glance v2 compatible
Extend servers context with "nics" parameter
Extend network context with "dns_nameservers" parameter
Extend volume context with "volume_type" parameter
Cleanup:
Mark several cleanup resources as tenant_resource
Nova servers and security groups are tenant related resources, but resource decorator missed that fact which makes cleanup tries to delete one resources several times.
Turn off redundant nova servers cleanup for NovaFlavors.list_flavors scenario
Add neutron cleanup for NeutronSecurityGroup.create_and_delete_security_groups
Exporter:
Rename task-exporter "file-exporter" to "file".
Warning
"file-exporter" is deprecated and will be removed in further releases.
Types:
Remove deprecated types.
Warning
you should use rally.task.types.convert instead of rally.task.types.set decorator
Validators
- Add a required_api_version validator
- Add validators for scenario arguments
Utils:
Use glance wrapper where appropriate to support compatibility between V1 and V2
Bug fixes¶
19 bugs were fixed:
Wrong arguments order of Keystone wrapper in case of V2 and V3
AttributeError while disabling urllib3 warnings on old installations
install_rally.sh script is failed while obtaining setuptools
"-inf" load duration in case of wrong runner plugin and failed start of contexts
Strange input task in the report
Wrong behaviour of boot_server_from_volume scenarios in case of booting server from image.
The arg of image must be None, when booting server from volume. Otherwise still boot server from image.
- Affected scenarios:
NovaServers.boot_server_from_volume NovaServers.boot_server_from_volume_and_delete NovaServers.boot_server_from_volume_and_resize NovaServers.boot_server_from_volume_and_live_migrate
Weak validation of json schema of RPS runner
JSON Schema of RPS runner doesn't have "required" field. It means that users are able to pass wrong configs and we will have runtime error while running task.
Rally doesn't take cacert setting while creating keystone session
Heat scenarios fail when API uses TLS
Example in comment of context manila_share_networks wrong
There is no way to get UUID of a verification after it is created by "rally verify start" or "rally verify import_results" when --no-use is set
Exposed ssh timeout and interval in vm scenario
Ceilometer scenario doesn't require "ceilometer" ctx
"servers" context requires setting network id for multiple possible networks found.
nested_level data type incorrect in create_nested_snapshots_and_attach_volume
Rally cleanup servers raises exception
Stopping server is redundant before cold-migrating server
existing_users context doesn't work in case of Keystone v3
Whether validates flavor's disk or not depends on booting type of the instance
Documentation¶
Re-use openstack theme for building docs outside rtd.
Add page for Verification component
Add glossary page
Adjust docs reference to "KeystoneBasic.authenticate" scenario
