OpenStack Liberty 릴리즈 노트


OpenStack Object Storage (Swift)

전체 릴리즈 노트는 https://github.com/openstack/swift/blob/master/CHANGELOG 에서 확인하세요.

새로운 기능

  • object-server 및/또는 복제 서버 구성을 위한 [DEFAULT] 구성 섹션 내 "servers_per_port" 에서, 새로운 0보다 큰 정수 구성 값을 활성화함으로써 1개 이상의 object-servers-per-disk 배포를 허용합니다. 설정하는 정수 값은 링에서 유일한 단일 로컬 포트 임의 값에 대해 서로 다른 object-server worker가 얼마나 많이 요청을 처리하는지에 따라 결정됩니다. 해당 모드에서는, 부모 swift-object-server 프로세스는 본래 사용자 (low-port 바인딩을 필요로 할 때는 root)로 계속하여 실행합니다. Ring에 정의된 모든 포트에 바인딩합니다. 그리고 나서 listen하는 소켓 당 worker에 대한 지정된 개수만큼 fork가 이루어집니다. 포트 당 자식 서버는 권한을 버리고 object-server worker가 항상 한 가지 예외: 'ring은 디스크 당 유일한 포트를 가지고, object-server는 단일 디스크에 대한 요청만을 처리함'을 가지는 방식으로 동작합니다. 부모 프로세스는 죽은 서버를 찾아 재시작시킵니다 (올바른 listen 소켓과 함께). 갱신된 ring 파일을 서버 상의 장치 및 새로운 포트와 함께 발견하였을 때 빠빈 서버들을 시작시킵니다. Ring 파일들은 "ring_check_interval"에 설정된 매개변수 값 (디폴트 15초) 마다 object-server에 구성된 일정에 따라 시작됩니다. 테스트에서는, 해당 배포 구성 (값이 3으로 설정됨)은 요청 latency를 줄이고, 초당 요청을 개선하며, 기존 "workers" 설정과 비교했을 때 느린 디스크 IO를 격리시킵니다. 이를 사용하기 위해서는, 각 장치는 서로 다른 포트를 사용하여 ring에 추가되어야만 합니다.
  • The object server includes a "container_update_timeout" setting (with a default of 1 second). This value is the number of seconds that the object server will wait for the container server to update the listing before returning the status of the object PUT operation. Previously, the object server would wait up to 3 seconds for the container server response. The new behavior dramatically lowers object PUT latency when container servers in the cluster are busy (e.g. when the container is very large). Setting the value too low may result in a client PUT'ing an object and not being able to immediately find it in listings. Setting it too high will increase latency for clients when container servers are busy.
  • Added the ability to specify ranges for Static Large Object (SLO) segments.
  • Allow SLO PUTs to forgo per-segment integrity checks. Previously, each segment referenced in the manifest also needed the correct etag and bytes setting. These fields now allow the "null" value to skip those particular checks on the given segment.
  • Replicator configurations now support an "rsync_module" value to allow for per-device rsync modules. This setting gives operators the ability to fine-tune replication traffic in a Swift cluster and isolate replication disk IO to a particular device. Please see the docs and sample config files for more information and examples.
  • Ring changes
    • Partition placement no longer uses the port number to place partitions. This improves dispersion in small clusters running one object server per drive, and it does not affect dispersion in clusters running one object server per server.
    • Added ring-builder-analyzer tool to more easily test and analyze a series of ring management operations.
    • Ring validation now warns if a placement partition gets assigned to the same device multiple times. This happens when devices in the ring are unbalanced (e.g. two servers where one server has significantly more available capacity).
  • TempURL fixes (closes CVE-2015-5223)

    Do not allow PUT tempurls to create pointers to other data. Specifically, disallow the creation of DLO object manifests via a PUT tempurl. This prevents discoverability attacks which can use any PUT tempurl to probe for private data by creating a DLO object manifest and then using the PUT tempurl to head the object.

  • Swift now emits StatsD metrics on a per-policy basis.
  • Fixed an issue with Keystone integration where a COPY request to a service account may have succeeded even if a service token was not included in the request.
  • Bulk upload now treats user xattrs on files in the given archive as object metadata on the resulting created objects.
  • Emit warning log in object replicator if "handoffs_first" or "handoff_delete" is set.
  • Enable object replicator's failure count in swift-recon.
  • Added storage policy support to dispersion tools.
  • Support keystone v3 domains in swift-dispersion.
  • Added domain_remap information to the /info endpoint.
  • Added support for a "default_reseller_prefix" in domain_remap middleware config.
  • Allow rsync to use compression via a "rsync_compress" config. If set to true, compression is only enabled for an rsync to a device in a different region. In some cases, this can speed up cross-region replication data transfer.
  • Added time synchronization check in swift-recon (the --time option).
  • The account reaper now runs faster on large accounts.
  • Various other minor bug fixes and improvements.

업그레이드 노트

  • 의존성 변경
    • six 라이브러리가 필요 조건으로 추가되었습니다. 파이썬 3 지원을 위한 사항입니다.
    • 파이썬 2.6 버전은 더이상 지원하지 않습니다.
  • 구성 변경
    • 파이썬 최신버전에서는 요청에 대한 허용 헤더 수 제한을 합니다 (기본 100). 이 숫자는 사용자 정의 미들웨어를 사용하는데 적은 수일수 있습니다. swift.conf에 새로운 extra_header_count 구성 값을 사용하여 허용 헤더 수를 수정할 수 있습니다.
    • "run_pause"의 이름이 "interval"로 변경되었습니다 (현재 구성에서는 "run_pause"와 같이 사용할 수 있습니다). 추후 버전에서는 "run_pause" 설정은 삭제됩니다.
  • Versioned writes 기능은 리팩토링되고 미들웨어로 재구현되었습니다. 프록시 pipeline에 "versioned_writes" 미들웨어를 추가하여야 하나, 만약 활성화된 경우라면, 기존 container 서버 구성 설정에서 삭제하거나 비활성되지 않습니다 ("allow_versions"). 기존 container 서버 구성 설정은 지속적인 사용가능 한 버전으로 기존 container를 활성화합니다. 더 많은 기능업그레이드에 대한 노트는 http://swift.openstack.org/middleware.html#how-to-enable-object-versioning-in-a-swift-cluster 를 참조하십시오.

OpenStack Networking (Neutron)

새로운 기능

  • Neutron은 IPv6 서브넷에 CIDR을 자동 할당하기 위해 이제 IPv6 접두어 위임을 지원합니다. 해당 기능에 대한 사용법 및 구성에 대한 자세한 정보는, OpenStack Networking Guide를 살펴봅니다.
  • Neutron이 이제 포트 수준에 대한 bandwidth 제한을 제공하는 QoS API를 처음 선보입니다. 해당 API, CLI, 구성 및 자세한 정보는 여기[1]에서 확인할 수 있습니다.
  • 라우터 고가용성 (L3 HA / VRRP)이 이제 2계층 population (l2pop)이 활성화되었을 때 동작합니다 [2].
  • VPNaaS 레퍼런스 드라이브가 이제 HA 라우터과 함께 동작합니다.
  • HA 라우터를 위한 VRRP 트래픽에 사용되던 네트워크가 이제 특정 세그멘테이션 유형 또는 물리 네트워크 태그를 사용하도록 구성할 수 있습니다 [3].
  • OVS 에이전트가 데이터 계층 연결에 영향을 미치지 않으면서 재시작 가능합니다.
  • Neutron이 이제 네트워크를 위한 역할 기반의 액세스 제어 (RBAC)를 제공합니다 [4].
  • LBaaS V2 레퍼런스 드라이버가 이제 운영급으로 확장 가능하고 안정적인 로드 밸런서 플랫폼인 Octavia를 기반으로 합니다.
  • LBaaS V2 API가 더 이상 실험적인 상태가 아닙니다. 이제 안정 버전입니다.
  • Neutron이 이제 수동으로 에이전트를 스케줄링하도록 관리하기 위한 방식을 제공하여, 호스트 자원들이 tenant 사용을 위하 활성화 되기 전에 테스트 가능합니다 [5].
  • Neutron이 이제 플러그인이 가능한 IP 주소 관리 프레임워크를 가짐으로써, 대체 가능한 또는 제3의 IPAM 사용을 가능하도록 합니다. 본래 버전에는 플러그인이 불가능한 버전의 IPAM이 기본으로 활성화되어 있습니다.

사용하지 않으며 제거된 플러그인 및 드라이버

  • 메타 플러그인이 Liberty 릴리즈에서 제거되었습니다.
  • IBM SDN-VE monolithic 플러그인이 Liberty 릴리즈에서 제거되었습니다.
  • Cisco N1kV monolithic 플러그인이 Liberty 릴리즈에서 제거되었습니다 (ML2 메커니즘 드라이버로 대체됨).
  • Embrane 플러그인은 사용하지 않으며 Mitaka 릴리즈에서 제거 예정입니다.

사용하지 않는 기능

  • FWaaS API는 Liberty에서 실험적인 상태로 정하였습니다. 또한, 현재 API는 Mitaka에서 제거될 예정이며 해당 팀에서 개발 진행 중인 새로운 FWaaS API로 대체될 예정입니다.
  • LBaaS V1 API가 사용하지 않는 상태로 정해졌으며 향후 릴리즈에서 제거 예정입니다. 앞으로 나아가기 위해, LBaaS V2 API가 사용되어야 합니다.
  • L3 에이전트를 위한 'external_network_bridge' 옵션은 사용되지 않는 상태이며 physnet에 bridge_mapping 사용을 권장합니다. 자세한 정보는, 네트워킹 가이드에서 해당 시나리오에 대한 "네트워크 노드" 섹션을 살펴 봅니다: http://docs.openstack.org/networking-guide/scenario_legacy_ovs.html

성능에 대한 고려 사항

  • 정체된 상태의 Trusty Tahr 커널 (3.13)은 네임스페이스 개수 증가함에 따라 "ip netns exec"를 실행할 때 비례하는 성능 저하를 보입니다. 확장이 중요한 경우, 이후 버전의 커널 (예: 3.19)가 사용되어야만 합니다. [3.13의 어떤 버전에서 보였는지 확인 필요. 대부분 버전들은 이미 수정된 상태일 것입니다.]

노트: 해당 성능 저하는 3.13.0-36.63 및 이후 커널 버전에서 수정되었을 것입니다. 자세한 레퍼런스를 위해서는 다음을 살펴봅니다 : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1328088
  • 하드웨어 가상화가 없는 환경에서 Neutron-LBaaS 로드 밸런서를 생성하면 Octavia 드라이버 사용시 느려질 수 있습니다. 이는 하드웨어 가상화가 사용 가능하지 않은 환경에서 KVM 가속기 대신 TCG 가속기를 사용하는 QEMU에 의한 것입니다. Compute 노드에서 하드웨어 가상화를 활성화하거나 가상 환경 안에서 Octavia 드라이버를 사용시에는 중첩 가상화를 사용할 것을 권장합니다. KVM 내 실행하는 DevStack을 위한 중첩 가상화를 설정하는 법에 대한 자세한 정보를 다음 링크에서 살펴봅니다: : http://docs.openstack.org/developer/devstack/guides/devstack-with-nested-kvm.html.

OpenStack Compute (Nova)

새로운 기능



Architectural evolution on the scheduler has continued, along with key bug fixes:

Cells v2

Cells v2 의 경우, 아직은 사용하지 않습니다. 그러나 일부 인프라에서 지원하도록 추가했습니다:

Compute 드라이버 기능


기타 기능

업그레이드 노트

  • If you are coming from Kilo stable, please make sure you have fully upgraded to the latest release of that lineage before deploying Liberty. Due to bug https://bugs.launchpad.net/nova/+bug/1474074 versions of Kilo from before the fix will be problematic when talking to Liberty nodes.
  • Allocation ratios for RAM and CPU are now defined within the nova-compute service (so per compute node). Ratios also need to be provided for the scheduler service. Depending on whether a compute node is running Kilo or Liberty, the allocation ratios will behave differently : if the compute node is running Kilo then the CPU and RAM allocation ratios for that compute node will be the ones defaulted in the controller's nova.conf file.Or, if the compute node is Liberty then you'll be able to set a per-compute allocation ratio for both CPU and RAM. In order to leave the operator providing the allocation ratios to all the compute nodes, the default allocation ratio will be set in nova.conf to 0.0 (even for the controller). That doesn't mean that allocation ratios will actually be 0.0, just that the operator needs to provide those before the next release (ie. Mitaka). To be clear, the default allocation ratios are still 16.0 for cpu_allocation_ratio and 1.5 for ram_allocation_ratio.
  • nova-compute should be upgraded to Liberty code before upgrading Neutron services per the new "network-vif-deleted" event: https://review.openstack.org/#/c/187871/
  • Rootwrap filters must be updated after release to add the 'touch' command.
    • There is a race condition between imagebackend and imagecache mentioned in the Launchpad Bug 1256838.
    • In this case if base image is deleted by ImageCacheManager while imagebackend is copying the image to instance path, then the instance goes in to error state.
    • In order to resolve this issue, there is a need to add 'touch' command in compute.filters along with the change https://review.openstack.org/#/c/217579/.
    • In case of a race condition, when libvirt has changed the base file ownership to libvirt-qemu while imagebackend is copying the image, then we get permission denied error on updating the file access time using os.utime. To resolve this error we need to update the base file access time with root user privileges using 'touch' command.
  • The DiskFilter is now part of the scheduler_default_filters in Liberty per https://review.openstack.org/#/c/207942/ .
  • Per https://review.openstack.org/#/c/103916/ you can now only map one vCenter cluster to a single nova-compute node.
  • The Libvirt driver parallels has been renamed to virtuozzo
  • Orphaned tables - iscsi_targets, volumes - have been removed.
  • The default paste.ini has been updated to use the new v2.1 API for all endpoints, and the v3 endpoint has been removed. A compatibility mode middlewear is used to relax the v2.1 validation for the /v2 and /v1.1 endpoints.
  • The code for DB schema downgrades has now been removed: https://blueprints.launchpad.net/nova/+spec/nova-no-downward-sql-migration
  • The default DB driver we test against is now pymysql rather than Python-MySQL
  • The "powervm" hv_type shim has been removed. This only affects users of the PowerVC driver on stackforge which are using older images with hv_type=powervm in the image metadata.
  • The minimum required version of libvirt in the Mitaka release will be 0.10.2. Support for libvirt < 0.10.2 is deprecated in Liberty: https://review.openstack.org/#/c/183220/
  • The libvirt.remove_unused_kernels config option is deprecated for removal and now defaults to True: https://review.openstack.org/#/c/182315/

사용하지 않는 기능

  • The ability to disable in tree API extensions has been deprecated (https://blueprints.launchpad.net/nova/+spec/nova-api-deprecate-extensions)
  • The novaclient.v1_1 module has been deprecated [[6]][[7]] since 2.21.0 and we are going to remove it in the first python-novaclient release in Mitaka.
  • Method `novaclient.client.get_client_class` is deprecated [[8]] since 2.29.0. The method will be removed in Mitaka.
  • The mute_weight_value option on weighers has been deprecated, including for use with Cells.
  • The remove_unused_kernels configuration option for the Libvirt driver is now deprecated.
  • The minimum recommended version of vCenter for use with the vcenter driver is now 5.1.0. In Liberty this is logged as a warning, in Mitaka support for versions lower than 5.1.0 will be removed.
  • API v3 specific components have all been deprecated and removed from the default paste.ini

OpenStack Telemetry (Ceilometer)

Key New Features

  • Creation of Aodh to handle alarming service.
  • Metadata caching - reduced load of nova API polling.
  • Declarative meters
    • Ability to generate meters by defining meter definition template.
    • Ability to define specific SNMP meters to poll.
  • Support for data publishing from Ceilometer to Gnocchi.
  • Mandatory limit - limit restricted querying is enforced. The limit must be explicitly provided on queries, otherwise the result set is restricted to a default limit.
  • Distributed, coordinated notification agents - support for workload partitioning across multiple notification agents.
  • Events RBAC support.
  • PowerVM hypervisor support.
  • Improved MongoDB query support - performance improvement to statistic calculations.
  • Additional meter support:
    • Magnum meters
    • DBaaS meters
    • DNSaaS meters

Gnocchi Features

  • Initial influxdb driver implemented.

Aodh Features

  • Event alarms - ability to trigger an action when an event is received.
  • Trust support in alarms link.

Upgrade Notes

  • The name of some middleware used by ceilometer changed in a backward incompatible way. Before upgrading, edit the paste.ini file for ceilometer to change oslo.middleware to oslo_middleware. For example, using sed -ri 's/oslo\.middleware/oslo_middleware/' api_paste.ini
  • The notification agent is a core service to collecting data in Ceilometer. It now handles all transformations and publishing. Polling agents now defer all processing to notification agents, and must be deployed in tandem.
  • A mandatory limit is applied to each request. If no limit is given, it will be restricted to a default limit.

Deprecated Features

  • Ceilometer Alarms is deprecated in favour or Aodh.
  • RPC publisher and collector is deprecated in favour of a topic based notifier publisher.
  • Non-metric meters are still deprecated, and are to be removed in a future release.

OpenStack Identity (Keystone)

새로운 주요 기능

  • Experimental: Domain specific configuration options can be stored in SQL instead of configuration files, using the new REST APIs.
  • Experimental: Keystone now supports tokenless authorization with X.509 SSL client certificate.
  • Configuring per-Identity Provider WebSSO is now supported.
  • openstack_user_domain and openstack_project_domain attributes were added to SAML assertion in order to map user and project domains, respectively.
  • The credentials list call can now have its results filtered by credential type.
  • Support was improved for out-of-tree drivers by defining stable Driver Interfaces.
  • Several features were hardened, including Fernet tokens, Federation, domain specific configurations from database and role assignments.
  • Certain variables in keystone.conf now have options, which determine if the user's setting is valid.

업그레이드 노트

  • The EC2 token middleware, deprecated in Juno, is no longer available in keystone. It has been moved to the keystonemiddleware package.
  • The compute_port configuration option, deprecated in Juno, is no longer available.
  • The XML middleware stub has been removed, so references to it must be removed from the keystone-paste.ini configuration file.
  • stats_monitoring and stats_reporting paste filters have been removed, so references to it must be removed from the keystone-paste.ini configuration file.
  • The external authentication plugins ExternalDefault, ExternalDomain, LegacyDefaultDomain, and LegacyDomain, deprecated in Icehouse, are no longer available.
  • keystone.conf now references entrypoint names for drivers. For example, the drivers are now specified as "sql", "ldap", "uuid", rather than the full module path. See the sample configuration file for other examples.
  • We now expose entrypoints for the keystone-manage command instead of a file.
  • Schema downgrades via keystone-manage db_sync are no longer supported. Only upgrades are supported.
  • Features that were "extensions" in previous releases (OAuth delegation, Federated Identity support, Endpoint Policy, etc) are now enabled by default.
  • A new secure_proxy_ssl_header configuration option is available when running keystone behind a proxy.
  • Several configuration options have been deprecated, renamed, or moved to new sections in the keystone.conf file.
  • Domain name information can now be used in policy rules with the attribute domain_name.

사용하지 않는 기능

  • Running Keystone in Eventlet remains deprecated and will be removed in the Mitaka release.
  • Using LDAP as the resource backend, i.e for projects and domains, is now deprecated and will be removed in the Mitaka release.
  • Using the full path to the driver class is deprecated in favor of using the entrypoint. In the Mitaka release, the entrypoint must be used.
  • In the [resource] and [role] sections of the keystone.conf file, not specifying the driver and using the assignment driver is deprecated. In the Mitaka release, the resource and role drivers will default to the SQL driver.
  • In keystone-paste.ini, using paste.filter_factory is deprecated in favor of the "use" directive, specifying an entrypoint.
  • Not specifying a domain during a create user, group or project call, which relied on falling back to the default domain, is now deprecated and will be removed in the N release.
  • Certain deprecated methods from the assignment manager were removed in favor of the same methods in the [resource] and [role] manager.

OpenStack Block Storage (Cinder)

Key New Features

  • A generic image caching solution, so popular VM images can be cached and copied-on-write to a new volume. Read docs for more info
  • Non-disruptive backups Read docs for more info.
  • Ability to clone consistency groups of volumes Read docs for more info.
  • List capabilities of a volume backend (fetch extra-specs).
  • Nested quotas.
  • Default LVM backends to be thin provisioned if available.
  • Corrected cinder service-list to show as Down when a driver fails to initialize.
  • Improved volume migration management:
    • Able to see if previous migration attempt was successful
    • Admins able to monitor migrations via cinder list
    • New volume status of 'maintenance' to prevent operations being attempted while migration is occurring
    • Improve backend volume name/id consistency after migration completes

Upgrade Notes

  • A change in parameters to RPC APIs and work on object conversion prevent running Liberty c-vol or c-api services with Kilo or earlier versions of either service.

Deprecated Features

  • Removed Simple and Chance Schedulers.
  • Removed deprecated HDS HUS iSCSI driver.
  • Removed Coraid driver.
  • Remove Solaris iSCSI driver.
  • Removed --force option for allowing upload of image to attached volume.
  • Marked the v1 API as deprecated.

OpenStack Orchestration (Heat)

새로운 기능


Convergence is a new orchestration engine maturing in the heat tree. In Liberty, the benefits of using the convergence engine are:

  • Greater parallelization of resource actions (for better scaling of large templates)
  • The ability to do a stack-update while there is already an update in-progress
  • Better handling of heat-engine failures (still WIP)

The convergence engine can be enabled by setting /etc/heat/heat/conf [DEFAULT] convergence_engine=true, then restarting heat-engine. Once this has been done, any subsequent created stack will use the convergence engine, while operations on existing stacks will continue to use the traditional engine.

Convergence has not been production tested and thus should be considered beta quality - use with caution. For the Liberty release, we recommend enabling convergence for the purposes of evaluation and scale testing. We will be considering making convergence the default engine in the Mitaka cycle. Convergence specific bugs are tracked in launchpad with the convergence-bugs tag.

Conditional resource exposure

Only resources actually installed in the cloud services are made available to users. Operators can further control resources available to users with standard policy rules in policy.json on per-resource type basis.

heat_template_version: 2015-10-15

2015-10-15 indicates that the YAML document is a HOT template and it may contain features added and/or removed up until the Liberty release.

  • Removes the Fn::Select function (path based get_attr/get_param references should be used instead).
  • If no <attribute name> is specified for calls to get_attr, a dict of all attributes is returned, e.g. { get_attr: [<resource name>]}.
  • Adds new str_split intrinsic function
  • Adds support for passing multiple lists to the existing list_join function.
  • Adds support for parsing map/list data to str_replace and list_join (they will be json serialized automatically)

REST API/heatclient additions

  • Stacks can now be assigned with a set of tags, and stack-list can filter and sort through those tags
  • "heat stack-preview ..." will return a preview of changes for a proposed stack-update
  • "heat template-validate --show-nested ..." will also validate all template resources and return nested data useful for building user interfaces
  • "heat resource-type-template --template-type hot ..." generates a template in HOT format
  • "heat resource-type-list" only shows types available to the user, and can filter results by name, version and support_status
  • "heat template-version-list" lists available template versions
  • "heat template-function-list ..." lists available functions for a template version

Enhancements to existing resources

New resources

The following new resources are now distributed with the Heat release:

[1] These existed Kilo as contrib resources as they were for non-integrated projects. These resources are now distributed with Heat as Big Tent projects.

[2] These existed Kilo as contrib resources as they require a user with an admin role. They are now distributed with Heat. Operators now have ability to hide them from under-privileged users by modifyig policy.json (for reference, OS::Nova::Flavor is hidden from non-admin users in default policy file supplied).

[3] These existed in Kilo as contrib resources as they used an approach not endorsed by the Heat project. They are now distributed with heat and documented as UNSUPPORTED.

[4] These resources are for projects which are not yet OpenStack Big Tent projects, so are documented as UNSUPPORTED

With the new OS::Keystone::* resources it is now be possible for cloud operators to use heat templates to manage Keystone service catalog entries and users.

Deprecated Resource Properties

Many resource properties have previously been documented as DEPRECATED. 15 of these properties are now flagged as HIDDEN, which means they will no longer be documented, but existing stacks and templates will continue to work after a heat upgrade. The [ http://docs.openstack.org/developer/heat/template_guide/openstack.html Resource Type Reference] should be consulted to determine available resource properties and attributes.

업그레이드 노트

Configuration Changes

Notable changes to the /etc/heat/heat.conf [DEFAULT] section:

  • hidden_stack_tags has been added, and stacks containing these tag names will be hidden from stack-list results (defaults to data-processing-cluster, which hides sahara-created stacks)
  • instance_user was deprecated, and is now removed entirely. Nova servers created with OS::Nova::Server resource will now boot configured with the default user set up with the cloud image. AWS::EC2::Instance still creates "ec2-user"
  • max_resources_per_stack can now be set to -1 to disable enforcement
  • enable_cloud_watch_lite is now false by default as this REST API is deprecated
  • default_software_config_transport has gained the option ZAQAR_MESSAGE
  • default_deployment_signal_transport has gained the option ZAQAR_SIGNAL
  • auth_encryption_key is now documented as requiring exactly 32 characters
  • list_notifier_drivers was deprecated and is now removed
  • policy options have moved to the [oslo_policy] section
  • use_syslog_rfc_format is deprecated and now defaults to true

Notable changes to other sections of heat.conf:

  • [clients_keystone] auth_uri has been added to specify the unversioned keystone url
  • [heat_api] workers now defaults to 4 (was previously 0, which created a worker per host CPU)

The policy file /etc/heat/policy.json can now be configured with per-resource-type access policies, for example:

   "resource_types:OS::Nova::Flavor": "rule:context_is_admin"

Upgrading from Kilo to Liberty

Progress has been made on supporting live sql migrations, however it is still recommended to bring down the heat service for the duration of the upgrade. Downward SQL schema migrations are no longer supported. A rollback to Kilo will require restoring a snapshot of the pre-upgrade database.

OpenStack Data Processing (Sahara)

  • 모든 Hadoop 1.X 버전 삭제

OpenStack Search (Searchlight)

This is the first release for Searchlight. Searchlight is intended to dramatically improving the search capabilities and performance of various OpenStack cloud services by offloading user search queries. It provides Keystone RBAC based searches across OpenStack services by indexing their data into ElasticSearch and providing a security layer on top of incoming search queries. ElasticSearch is a search server based on Lucene. It provides a distributed, scalable, near real-time, faceted, multitenant-capable, and full-text search engine with a RESTful web interface.

OpenStack DNS (Designate)

새로운 주요 기능

  • Experimental: Hook Point API
  • Horizon Plugin moved out of tree
  • Purging deleted domains
  • Ceilometer "exists" periodic event per domain
  • ASync actions
    • Import
    • Export
  • Active /passive failover for designate-pool-manager periodic tasks
  • OpenStack client integration

Addtional DNS Server Backends

  • InfoBlox
  • Designate

업그레이드 노트

  • New service designate-zone-manager
    • It is recommended to use a supported tooz backend.
    • ZooKeeper is recommended, or anything supported by tooz.
    • If a tooz backend is not used, all zone-managers will assume ownership of all zones, and there will be 'n' "exists" messages per hour, where 'n' is the number of zone-manager processes.
  • designate-pool-manager can do active/passive failover for periodic tasks.
    • It is recommended to use a supported tooz backend.
    • If a tooz backend is not used, all pool-managers will assume ownership of the pool, and multiple periodic tasks will run. This can result in unforeseen consequences.

사용하지 않는 기능

  • V1 API
    • An initial notice of intent, as there are operations that still require the Designate CLI interface which talks to V1, and Horizon panels that only talk to V1.

OpenStack Messaging Service (Zaqar)

Key New Features

  • Pre-signed URL - A new REST API endpoint to support pre-signed URL, which provides enough control over the resource being shared, without compromising security.
  • Email Notification - A new task driver for notification service, which can take a Zaqar subscriber's email address. When there is a new message posted to the queue, the subscriber will receive the message by email.
  • Policy Support - Support fine-grained permission control with the policy.json file like most of the other OpenStack components.
  • Persistent Transport - Added support for websocket as a persistent transport alternative for Zaqar. Now users will be able to establish long-lived connections between their applications and Zaqar to interchange large amounts of data without the connection setup adding overhead.

OpenStack Dashboard (Horizon)

새로운 주요 기능

  • 플러그인 개선 - Horizon에서 포함(inclusion)한 JavaScript 파일을 자동으로 확인(discover)하고, SCSS와 Django 템플릿을 덮어쓸 수 있는 플러그인 매커니즘을 가지고 있습니다.

Ironic has switched to an intermediate release model and released version 4.0 during Liberty, followed by two minor updates. Version 4.2 forms the basis for the OpenStack Integrated Liberty release and will receive stable updates.

Please see full release notes here: http://docs.openstack.org/developer/ironic/releasenotes/index.html

새로운 기능

  • Added "ENROLL" hardware state, which is the default state for newly created nodes.
  • Added "abort" verb, which allows a user to interrupt certain operations while they are in progress.
  • Improved query and filtering support in the REST API.
  • Added support for CORS middleware.

하드웨어 드라이버

  • Added a new BootInterface for hardware drivers, which splits functionality out of the DeployInterface.
  • iLO virtual media drivers can work without Swift.
  • Added Cisco IMC driver.
  • Added OCS Driver.
  • Added UCS Driver.
  • Added Wake-On-Lan Power Driver.
  • ipmitool driver supports IPMI v1.5.
  • Added support to SNMP driver for “APC MasterSwitchPlus” series PDU’s.
  • pxe_ilo driver now supports UEFI Secure Boot (previous releases of theiLO driver only supported this for agent_ilo and iscsi_ilo).
  • Added Virtual Media support to iRMC Driver.
  • Added BIOS configuration to DRAC Driver.
  • PXE drivers now support GRUB2.

사용하지 않는 기능

  • The "vendor_passthru" and "driver_vendor_passthru" methods of the DriverInterface have been removed. These were deprecated in Kilo and replaced with the @passthru decorator.
  • The migration tools to import data from a Nova "baremetal" deployment have been removed.
  • Deprecated the "parallel" option to periodic task decorator.
  • Removed deprecated ‘admin_api’ policy rule.
  • Support for the original "bash" deploy ramdisk is deprecated and will be removed in two cycles. The ironic-python-agent project should be used for all deploy drivers.

업그레이드 노트

  • Newly created nodes default to the new ENROLL state. Previously, nodes defaulted to AVAILABLE, which could lead to hardware being exposed prematurely to Nova.
  • The addition of API version headers in Kilo means that any client wishing to interact with the Liberty API must pass the appropriate version string in each HTTP request. Current API version is 1.14.

OpenStack Key Manager (Barbican)

새로운 기능

  • Added the ability for project administrators to create certificate authorities per project. Also, project administrators are able to define and manage a set of preferred certificate authorities (CAs) per project. This allows projects to achieve project specific security domains.
  • Barbican now has per project quota support for limiting number of Barbican resources that can be created under a project. By default the quota is set to unlimited and can be overridden in Barbican configuration.
  • Support for a rotating master key which is used for wrapping project level keys. In this lightweight approach, only the project level key (KEK) is re-wrapped with new master key (MKEK). This is currently applicable only for the PKCS11 plug-in. (http://specs.openstack.org/openstack/barbican-specs/specs/liberty/add-crypto-mkek-rotation-support-lightweight.html)
  • Updated Barbican's root resource to return version information matching Keystone, Nova and Manila format. This is used by keystoneclient's versioned endpoint discovery feature.
  • Removed administrator endpoint as all operations are available on a regular endpoint. No separate endpoint is needed as access restrictions are enforced via Oslo policy.
  • Added configuration for enabling sqlalchemy pool for the management of SQL connections.
  • Added ability to list secrets which are accessible via ACL using GET /v1/secrets?acl-only=true request.
  • Improved functional test coverage around Barbican APIs related to ACL operations, RBAC policy and secrets.
  • Fixed issues around creation of SnakeOil CA plug-in instance.
  • Barbican client CLI can now take a Keystone token for authentication. Earlier only username and password based authentication was supported.
  • Barbican client now has ability to create and list certificate orders.
