You just need to reduce the indent of the with_nested line like this:

- name: start container
docker_container:
name: "tomcat-container"
image: "tomcat-images"
state: started
ports:
- "{{ item[0]}}:{{ item[1] }}"
with_nested:
- [8080,8080]
- [8081,8081]


with_nested is an option for the task and the way you had it indented it was an option for the module (docker_container).
