Customize the Update Configuration for Distributed Cloud Update Orchestration¶
You can adjust how the nodes in each system (Central Cloud’s RegionOne and/or Subclouds) are updated.
About this task
The update strategy for Distributed Cloud Update Orchestration uses separate configuration settings to control how the nodes on a given system are updated. You can adjust the settings used by default for Central Cloud’s RegionOne and all subclouds, and you can create custom settings for individual subclouds.
You can change the configuration settings before or after creating a update strategy for Distributed Cloud update orchestration. The settings are maintained independently.
Select the SystemController region.
Select Distributed Cloud Admin > Software Management.
On the Software Management page, select the Cloud Patching Configuration tab.
Take one of the following actions:
To edit the settings applicable to RegionOne and all subclouds by default, click Edit Configuration in the all clouds default row.
To save your changes, click Edit Cloud Patching Configuration.
To create custom settings for an individual subcloud, click Create New Cloud Patching Configuration.
In the Subcloud field, select the subcloud for the custom settings.
To save your configuration changes, click Create Cloud Patching Configuration. The new configuration is added to the list.
