Some embodiments provide a novel method for resiliently associating Internet Protocol (IP) addresses with pods that each have unique identifiers (IDs) in a managed cluster of worker nodes managed by a first set of one or more controllers of the managed cluster. The resilient association between IP addresses and pods is maintained even when pods are moved between worker nodes. At a second set of controllers, the method receives notification regarding deployment, on a first worker node, of a stateful pod associated with a particular ID. The method allocates an IP address to the stateful pod. The method creates a mapping between the IP address and the particular ID in order to maintain the allocation of the IP address to the stateful pod. The method provides the IP address to the first set of controllers to use for the stateful pod.

Assigning stateful pods fixed IP addresses depending on unique pod identity

Example methods and systems for container-based connectivity check in a software-defined networking (SDN) environment are disclosed. One example method may comprise detecting, a request for a connectivity check between a first container-based resource and a second container-based resource; identifying a first logical network element and a second logical network element; and injecting a connectivity check packet at the first logical network element for forwarding towards the second logical network element. The example method also may comprise: obtaining report information associated with one or more intermediate logical network elements located along a path that is traversed by the connectivity check packet; and determining a connectivity status associated with the first container-based resource and the second container-based resource based on the report information.

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.

Certain embodiments of the present disclosure include a method for translating an application-level abstraction to a logical network topology. The method includes receiving an event request from a container orchestrator at an orchestrator adaptor. The method also includes translating the event request to a logical network resource via an application programming interface associated with a network virtualization platform. The method includes mapping the event request to the logical network resource. The method also includes deploying the logical network resource in a logical network via the network virtualization platform.
