Ansible in Docker container refuses to communicate with other Docker container
I am currently facing a problem where my ping module I defined in my playbook.yml file refuses to connect to a different docker container. The Ansible environment is setup in a Docker container as well. The Docker service I am trying to do a ping to is called "postgres_container". The weird thing is, if I do a ping from within the ansible container with the command "ping postgres_container" it succesfully connects and stays connected. However, If I try to run the command from within my playbook.yml file, it fails.
my hosts file:
my playbook.yml file:
- hosts: database
- name: test connection
