Red Hat build of MicroShift

Default settings

The Generic Device Plugin for MicroShift is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.

For more information about the support scope of Red Hat Technology Preview features, see Technology Preview Features Support Scope.

When no config.yaml or configuration snippet exists, MicroShift uses built-in default values. To view these defaults, run microshift show-config.

The following example shows the default configuration settings.

Procedure

To see the default values, run the following command:

$ microshift show-config
