Question: Ulimit with services.create ?

I'm trying to migrate some of my code to docker swarm and even though I can do

docker service create --ulimit nofile=66535 alpine sleep infinity

and I can do

import docker
_client = docker.from_env()
_container = _client.containers.run(image="alpine", command="sleep infinity", ulimits=[docker.types.Ulimit(name="nofile", soft=65535, hard=65535)], detach=True)

or even

import docker

_client= docker.from_env()
_service = _client.services.create(image="alpine", command="sleep infinity")

I however have no way of passing the ulimit value to the created service. Any ideas ?

Start at the Python services.create entry point and compare its available options with the Docker CLI service create command shown in the issue. Trace how service creation options are sent to the Docker Engine API, then verify that a nofile ulimit can be passed and preserved when creating a service.
