Ansible task for run Docker container from private registry - ansible

Question

I have a private Docker registry runnning in 172.20.20.20 in port 5000. And I have pushed the image pruebasjeje to it.
Now, I need to pull and run the image using Ansible task:
- name: run container
docker:
registry: 172.20.20.20:5000
insecure_registry: true
image: pruebasjeje
state: reloaded
pull: always
ports:
- "8080:8080"
But when I execute it, I get this error:
fatal: [localhost]: FAILED! => {"changed": false, "changes":
["{\"status\":\"Pulling repository
docker.io/library/pruebasjeje\"}\r\n",
"{\"errorDetail\":{\"message\":\"Error: image
library/pruebasjeje:latest not found\"},\"error\":\"Error: image
library/pruebasjeje:latest not found\"}\r\n"], "failed": true, "msg":
"Unrecognized status from pull.", "status": ""}
It seems that is looking for the image in docker.io. How should I write my task in order to do what I want?
Thanks.

Not sure if it is how it should be done, but this is how I do it:
- name: run container
docker:
insecure_registry: true
image: 172.20.20.20:5000/pruebasjeje
state: reloaded
pull: always
ports:
- "8080:8080"
I just started with Docker myself. Here are the tasks I have for setting up Docker on my target host (CentOS 7):
- name: Install epel repo
yum:
name: "http://download.fedoraproject.org/pub/epel/{{ ansible_distribution_major_version }}/{{ ansible_userspace_architecture }}{{ '/' if ansible_distribution_major_version < '7' else '/e/' }}epel-release-{{ ansible_distribution_major_version }}-5.noarch.rpm"
state: present
become: yes
- name: Install Docker
yum:
name: "{{ item }}"
state: latest
enablerepo: epel
with_items:
- device-mapper
- docker-engine
- python-pip
become: yes
- name: Install docker-py
pip:
name: docker-py
become: yes
- name: Add registry cert
copy:
src: registry.crt
dest: /etc/docker/certs.d/{{ docker_registry_host }}/ca.crt
become: yes
- name: Allow access to insecure registry
lineinfile:
dest: /usr/lib/systemd/system/docker.service
regexp: ^ExecStart=
line: ExecStart=/usr/bin/docker daemon -H fd:// --insecure-registry {{ docker_registry_host }}:5000
become: yes
- name: Start Docker service
