How to create a SSH connection between Ansible and Jenkins containers

I'm new to Jenkins.

My goal is to create a Jenkins job\pipeline that will activate a group of ansible's playbook files - which will create a long installation of my tested product.

I build 2 containers in Docker desktop (Windows): Ansible and Jenkins.

Below Ansible docker-compose.yml file:

version: '2'
services:
  ansible:
    container_name: ansible
    hostname: ansible
    image: ansible
    volumes:
      - ~/product/ansible:/ansible
    working_dir: /ansible
    build:
      context: .
      dockerfile: Dockerfile
    dns:
      - 200.20.0.20
    networks:
    - network

networks:
  network:
    external: true

Below Jenkins docker-compose.yml file:

version: '3.7'
services:
  jenkins:
    container_name: jenkins
    image: jenkins/jenkins:lts
    privileged: true
    user: root
    ports:
      - 8080:8080
      - 50000:50000
    container_name: jenkins
    volumes:
    - ~/r10_core/jenkins:/jenkins
    networks:
    - network

networks:
  network:
    external: true

Ansible and Jenkins are on the same Network Id. So, ping command is working from Ansible to Jenkins and vis versa. Both containers have access to Internet.

I set username and password admin | admin and installed the following plugins in Jenkins container through Jenkins site > Manage Jenkins > Manage Plugins:

• Ansible plugin
• SSH
• Publish by SSH

I checked the SSH services in both machines.

Ansible:

[root@ansible ansible]# ssh 172.20.0.2
ssh: connect to host 172.20.0.2 port 22: Connection refused
[root@ansible ansible]# service --status-all
bash: service: command not found
[root@ansible ansible]# systemd
bash: systemd: command not found
[root@ansible ansible]# systemctl
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
[root@ansible ansible]#

Jenkins:

root@jenkins:/# ssh 172.20.0.3
ssh: connect to host 172.20.0.3 port 22: Connection refused
root@jenkins:/# service --status-all
 [ ? ]  hwclock.sh
root@jenkins:/#

I got a Connection refused also when trying to connect to the machines themselves

a) What should I configure in the Ansible container in order SSH to be active? b) What should I configure in the Jenkins container in order SSH to be active? c) What should I configure in each container in order them talk each other through SSH (i.e port 22)?
