Configuring a compute node to perform services on a host

Abstract

Some embodiments provide a novel method for configuring a service data compute node (DCN) executing on a host computer to perform network services (e.g., firewall, load balancing, intrusion detection, network address translation (NAT), other middlebox services, etc.) for several DCNs executing on the host computer. The method receives, at the service DCN, an identification of a set of container specifications that will be implemented (e.g., will be executed by) the service DCN. The method then retrieves the identified set of container specifications (e.g., container images) from a container repository storing multiple received container specifications. In some embodiments, the container specifications include container images generated by a third party service partner for providing a particular service or set of services and stored in a container repository. The method then instantiates the retrieved containers to provide the identified network services to data messages received at the service DCN.
