Documentation RFE: Advanced Topics - ComponentConfig

[fgiloux]

I could not find any reference to ComponentConfig in operator-sdk documentation: https://book.kubebuilder.io/component-config-tutorial/tutorial.html

This is an important aspect for controlling any advance functionality of the controller:

• cleansing policies
• sync period
• logging level
• feature gates

IMHO this should be part of best practices for development of any advanced operator.

The current alternative of relying on feature flags has several limitations, for instance:

• any configuration change requires the controller deployment to be changed and the controller to be restarted
• this does not support any data structure / validation and little self documentation
• this is not gitOps friendly: the deployment is created at installation time and needs to be patched afterwards, whereas a configuration resource can just be applied onto the default one.

should probably go in this section: https://sdk.operatorframework.io/docs/best-practices/

I can take a look into it. I recently worked on --component-config flag enablement in Kubebuilder.
