IllegalStateException: More than 1 secondary resource related to primary

[brainwang]

Bug Report

What did you do?

I developed a simple operator with 2 different ConfigMap as secondary resources.

What did you expect to see?

I hope it can be handled correctly

What did you see instead? Under which circumstances?

A runtime exception was throw:
Caused by: java.lang.IllegalStateException: More than 1 secondary resource related to primary

Hi @brainwang ,

this comes in the next version, until that time please don't use dependent resources for this use case.
See: #1175

[brainwang]

Thanks @csviri
Could you please tell me when the next release will be out?

Could you please tell me when the next release will be out?

Good question, hard to tell because of the holiday season :) There are few important issues that has priority, see:

https://github.com/java-operator-sdk/java-operator-sdk/milestone/3

My guestimate is mid September.

[csviri]

(Note that this issue is already on that list)

[csviri]

We might do an other release meanwhile, if we are able to settle a nice API for this. Will let you know asap.

[csviri]

Will close this issue for now if no objections.

@brainwang sorry forgot to mention that there is a workaround, to put labels on the resources, to distinguish them:

https://github.com/java-operator-sdk/java-operator-sdk/blob/e3cd675db586e3b9f5ebf4fbe7b85b69b0bd3d1e/operator-framework/src/test/java/io/javaoperatorsdk/operator/sample/orderedmanageddependent/OrderedManagedDependentTestReconciler.java

in this way you can use multiple of them
