Example methods and systems for container-based network policy configuration in a software-defined networking (SDN) environment are disclosed. One example method may comprise: in response to detecting a first request to assign a container-based resource with a first label via a container orchestration system, assigning a logical network element associated with the container-based resource with a second label. The example method may also comprise: in response to detecting a second request to configure a container-based network policy associated with the container-based resource via the container orchestration system, identifying the logical network element by mapping the first label to the second label; and configuring the container-based network policy to be applicable to network traffic that is forwarded via the logical network element.
