【问题描述】：

I am using spring boot drools. I would like to maintain say 3 different drl files for different context as the rules are different for different context. In this case should I create 3 key KieContainer for each context or is it possible to handle in just on kie container? Note: for each context I have to invoke only the corresponding drl rules

Based on the limited description, sounds like "different context" can be identified with a Knowledge Base (KieBase).

You can create 1 KJAR with the 3 different DRL files, making sure (e.g.: via package) they correspond to 3 different KieBases.

Something ~like:

<kmodule>
 <kbase name="KBase1" packages="org.acme,org.context1" />
 <kbase name="KBase2" packages="org.acme,org.context2" />
 <kbase name="KBase3" packages="org.acme,org.context3" />
 ...
</kmodule>

Then you could create 1 KieContainer, which contains the single KJAR containing the "multiple contexts" (KieBases).

At that point, from the KieContainer, you can create a KieSession with the specific KieBase you want.
