Reducing overlay network overhead across container hosts

A system comprising:

• a memory;
• at least one processor in communication with the memory;
• a first container and a second container running on a first host, wherein each of the first container and second container expose at least one network service port;
• and
• a container scheduler executing on the at least one processor, wherein the container scheduler executes on the at least one processor to:
• assign a network complexity weight to the first host, wherein the network complexity weight is based on a quantity of network service ports that the first container and the second container expose,
• filter a plurality of hosts based on resource availability corresponding to each host of the plurality of hosts,
• rank the plurality of hosts based on a respective network complexity weight corresponding to each host of the plurality of hosts, and
• dispatch a third container to a second host of the plurality of hosts based on the resource availability and network complexity weight corresponding to the second host.

A non-transitory machine readable medium storing code, which when executed by at least one processor, causes a container scheduler to:

• assign a network complexity weight to a first host, wherein the network complexity weight is based on a quantity of network service ports that a first container and a second container running on the first host expose;
• filter a plurality of hosts based on resource availability corresponding to each host of the plurality of hosts;
• rank the plurality of hosts based on a respective network complexity weight corresponding to each host of the plurality of hosts;
• and
• dispatch a third container to a second host of the plurality of hosts based on the resource availability and the network complexity weight corresponding to the second host.
