How does Skywalking identify whether an application is containerized or on-premises?

If you are using agent mode, this should be transparent. We should not know that.
If you have k8s monitoring, then we have a hierarchy structure to tell.

From a tech perspective, containerized should not be seen from agent internally.

You could use this. agent.instance_properties_json=${SW_INSTANCE_PROPERTIES_JSON:}. But to be honest, this is not whether it is containerized; it is just a system variable value. You have to trust your script anyway.
