红帽全球峰会1.2. The MicroShift configuration file
At startup, MicroShift checks the system-wide /etc/microshift/ directory for a configuration file named config.yaml. If the configuration file does not exist in the directory, built-in default values are used to start the service.
You must use the MicroShift configuration file in combination with host and, sometimes, application and service settings. Ensure that you configure each function in tandem when you adjust settings for your MicroShift node.
For your convenience, a config.yaml.default file ready for your inputs is automatically installed.
1.2.1. Default settings
If you do not create a config.yaml file or use a configuration snippet YAML file, default values are used. The following example shows the default configuration settings.
To see the default values, run the following command:
$ microshift show-configDefault values example output in YAML form
