## 理解 DaemonSet 版本

<!--
|

## Understanding DaemonSet revisions
|
||||
|
||||
在前面的 `kubectl rollout history` 步骤中,您获得了一个版本列表,每个版本都存储在名为
|
||||
`ControllerRevision` 的资源中。 `ControllerRevision` 仅在 Kubernetes 1.7 及以后的版本中可用。
|
||||
In the previous `kubectl rollout history` step, you got a list of DaemonSet
|
||||
revisions. Each revision is stored in a resource named ControllerRevision.
|
||||
|
||||
查找原始的版本资源,来查看每个版本中存储了什么内容:
|
||||
To see what is stored in each revision, find the DaemonSet revision raw

## 理解 DaemonSet 修订版本
|
||||
|
||||
在前面的 `kubectl rollout history` 步骤中,你获得了一个修订版本列表,每个修订版本都存储在名为
|
||||
`ControllerRevision` 的资源中。
|
||||
|
||||
要查看每个修订版本中保存的内容,可以找到 DaemonSet 修订版本的原生资源:
|
||||
|
||||
```shell
|
||||
kubectl get controllerrevision -l <daemonset-selector-key>=<daemonset-selector-value>
|
||||
```
|
||||
|
||||
<!--
|
||||
This returns a list of ControllerRevisions:
|
||||
-->
|
||||
该命令返回 `ControllerRevisions` 列表:
|
||||
|
||||
```shell
|
||||
```
|
||||
NAME CONTROLLER REVISION AGE
|
||||
<daemonset-name>-<revision-hash> DaemonSet/<daemonset-name> 1 1h
|
||||
<daemonset-name>-<revision-hash> DaemonSet/<daemonset-name> 2 1h
|
||||
```
|
||||
|
||||
<!--
|
||||
Each ControllerRevision stores the annotations and template of a DaemonSet
|
||||
revision.
|
||||
-->
|
||||
每个 `ControllerRevision` 中存储了相应 DaemonSet 版本的注解和模板。
|
||||
|
||||
`kubectl rollout undo` 采用特定 `ControllerRevision` ,并用
|
||||
<!--
|
||||
`kubectl rollout undo` takes a specific ControllerRevision and replaces
|
||||
DaemonSet template with the template stored in the ControllerRevision.
|
||||
`kubectl rollout undo` is equivalent to updating DaemonSet template to a
|
||||
previous revision through other commands, such as `kubectl edit` or `kubectl
|
||||
apply`.
|
||||
-->
|
||||
`kubectl rollout undo` 选择特定的 `ControllerRevision`,并用
|
||||
`ControllerRevision` 中存储的模板代替 DaemonSet 的模板。
|
||||
`kubectl rollout undo` 相当于通过其他命令(如 `kubectl edit` 或 `kubectl apply`)将 DaemonSet 模板更新至先前的版本。
|
||||
`kubectl rollout undo` 相当于通过其他命令(如 `kubectl edit` 或 `kubectl apply`)
|
||||
将 DaemonSet 模板更新至先前的版本。
|
||||
|
||||
注意 DaemonSet 版本只会向前滚动。 也就是说,回滚完成后,所回滚到的 `ControllerRevision` 版本号 (`.revision` 字段) 会增加。 例如,如果用户在系统中有版本 1 和版本 2,并从版本 2 回滚到版本 1 ,带有 `.revision: 1` 的`ControllerRevision` 将变为 `.revision: 3`。

## 故障排除

* 查看 [DaemonSet 滚动升级故障排除](/docs/tasks/manage-daemon/update-daemon-set/#troubleshooting)。
|
||||
<!--
|
||||
DaemonSet revisions only roll forward. That is to say, after a
|
||||
rollback completes, the revision number (`.revision` field) of the
|
||||
ControllerRevision being rolled back to will advance. For example, if you
|
||||
have revision 1 and 2 in the system, and roll back from revision 2 to revision
|
||||
1, the ControllerRevision with `.revision: 1` will become `.revision: 3`.
|
||||
-->

||||

|
||||
注意 DaemonSet 修订版本只会正向变化。也就是说,回滚完成后,所回滚到的
