Deployment models with licence vs free

Hi,

I am newbie, exploring deployment option and licence requirements. I’ve read lot of docs. I would like to validate my assumption here though.

Am I right that Standalone Container deployed on Docker does NOT require a licence key whereas on K8s it DOES? Please see step. 3 here where it states:

LangGraph Cloud License Key
 You can get this from your LangChain representative. Contact us at sales@langchain.dev for more information.

But then I get confused because then I could use the same Docker image and just run it on K8s without a licence key. So what do I miss?

thanks
