Mitaka版本发布说明

1.0.0

新特性

  • We no longer support soft-delete in senlin database. Marking an entity as soft-deleted is causing more problems than bringing any convenience.

  • Action列表现在可以通过它的status属性过滤。

  • 为action添加了多租户支持。

  • 添加了senlin.policy.affinity-v1.0，它可以被用来控制基于nova servergroup设置的虚拟机服务器如何被place。

  • New actions for checking and recovering nodes/clusters are added.

  • 为集群和节点的检查和恢复添加了新的API。

  • 为限定每个项目的集群个数添加了支持。

  • 当集群的规模正在被改变时，它现在有一个新状态’RESIZING’。

  • The built-in deletion policy can handle cross-region and cross-zone nodes selection.

  • 使用senlin管理命令，支持引擎状态检查。

  • 事件列表现在可以通过’level’属性过滤。

  • 为事件资源添加了多租户支持。

  • Profile types and policy types are explicitly versioned now. We have the version string appended to the type names for easier detection.

  • New health check daemon is introduced to do periodical cluster status checking. It collaborates with health policy on cluster monitoring.

  • Improved action scheduler so that it can pick an action that is READY to be executed from DB.

  • 负载均衡策略1.0版添加了LBaaS健康监测支持。

  • Added support to steal a lock from dead engine.

  • 当查找资源时，添加了多租户支持，也就是project_safe检查。

  • Use ‘sort’ instead of ‘sort_keys’ and ‘sort_dir’ for object sorting.

  • Nova server profile now supports block device mapping v2 (BDMv2).

  • 允许nova服务器的样版的‘flavor’属性的更新操作。

  • 允许nova服务器的样版的‘name’属性的更新操作。

  • 添加了样版属性检查，不论样版是否可更新。

  • Support to ‘senlin-manage purge_deleted <age> [<unit>]’ is added.

  • New abstraction ‘receiver’ has been added as a generic way to notify the senlin engine that something interesting has happened.

  • An experimental policy for placing nodes across multiple regions.

  • Removed support to ‘trigger’ abstraction.

  • Make sure ‘spec’ of a profile is immutable after a profile object is created. The only way to “update” a profile is to create a new one.

  • 添加了命令“senlin-manage service list”来显示engine的状态。

  • 添加了命令“senlin-manage service clean”来清理死亡的engine记录。

  • 为更新Nova server的镜像属性添加支持。

  • 为更新nova服务器的网络属性添加了支持。

  • 当创建os.nova.server样版时，镜像ID和名称都是支持的。

升级说明

  • Database tables have to be recreated as we have removed soft-delete support from both the DB layer and the engine layer.

  • Senlin API从它的端点中删除了’tenant_id’。这意味着用户如果已经有了一个老的安装，则必须重新创建他们的keystone端点。

  • Webhook abstraction is removed. New usage model of webhooks is through the ‘receiver’ abstraction.

  • Node actions NODE_JOIN and NODE_LEAVE are removed from API surface.

  • Removed cluster policy enable/disable support. We will use more generic interface cluster policy update for these use cases.

  • Removed permission property from profiles. We will devise an RBAC mechanism as an alternative.

  • 状态`DELETED`从集群和节点中删除了。

  • Timestamp fields like ‘created_time’ and ‘udpated_time’ are renamed to ‘created_at’ and ‘updated_at’ respectively.

  • As a side-effect of the rework of action dependency, a new table has been added to the database.

  • Senlin binaries are all made as console script entries.

Bug修复

  • When referenced objects are not found in an API request, 400 is returned now.

  • Reworked action status check so that a cluster action will always return from WAITING status.

  • Fixed profile type checking error when attaching affinity policy.

  • Fixed parsing of default values for ‘max_size’ and ‘min_size’ properties of a cluster.

  • Fixed race condition in service deletion.

  • Fixed APIs that spawn asynchronous operations to return 202 as status code.

  • Fixed a bug related to setting the next_index property of a cluster after new nodes have joined or existing nodes have left.

  • Fixed cluster-list function so that ‘global-project’ can be specified.

  • Removed useless parameters (‘user’, ‘project’, etc.) from filtering when listing clusters.

  • 为cluster-policy-attach添加了参数过滤。

  • Fixed RC/role checking in the setup-service script.

  • Enforce multi-tenancy checking when a non-admin user attempting to list resources from projects other than that of the requesting user.

  • Fixed a bug related to using the ‘name’ property of a nova server profile.

  • Fixed parameter checking when listing resources, such as sort and filters.

  • 为API policy-create的调用添加了参数检查。

  • 为API cluster-policy-detach的调用添加了参数检查。

  • 为API cluster-policy-update的调用添加了参数检查。

  • Reworked action dependency to avoid indefinite waiting problem.

  • Fixed trust usage when interacting with keystone. This enables senlin to be deployed on a Juno version OpenStack.
