Operator config by the admin

Greetings folks,

I would like to have the admin enable/disable certain operator functionalities using environment variables set by the admin who installs the operator by creating a Subscription.

Setting the Subscription's spec.config.env works great.

I wonder if the community has an opinion on that compared to having the operator code read config from a well-known configmap.

Thanks,

Shoubhik

Another pattern I've seen used a few times is the having a separate CR which works much like a ConfigMap, but includes custom validation.

I may have missed something but having a way to provide specific configuration when installing an operator appears to be missing.

I've been writing operators that configure external systems such as Vault and these have different target URLs is different environments.

It would be great to have this supported by OLM such that you could define configuration and possibly provide defaults that could be overridden.

This is possible, see: https://github.com/operator-framework/operator-lifecycle-manager/blob/master/doc/design/subscription-config.md

It's not a first class experience in our UI or official docs yet, because an Operator should always come up and be configured after the fact. E.g. you can think about Operators taking a user-specific configuration either on a per-API/request basis or pick it up from a ConfigMap or custom Config object on a per-namespace basis.
