Copy file to docker container via Ansible

I want to copy a file to a docker container, as one of my Ansible playbook steps. I create the file with jinja2 "template". I can copy the file in /tmp/ and the run a command to copy it to the docker container, such as:
`docker cp /tmp/config.json my_image:/app/config/path/`
But I'm looking for the better way not to use "/tmp" or like that.

Ansible has a docker connection plugin that you can use to interact with existing containers in your playbook. For example, if I have a container named mycontainer:

$ docker ps
CONTAINER ID   IMAGE     COMMAND       CREATED         STATUS         PORTS     NAMES
07899303ac55   alpine    "sleep inf"   7 seconds ago   Up 2 seconds             mycontainer

I can create an Ansible inventory like this that sets the ansible_connection variable to community.general.docker:

all:
  hosts:
    mycontainer:
      ansible_connection: community.docker.docker    

Now I can target the container in a play like this:

- hosts: mycontainer
  gather_facts: false
  become: true
  tasks:
    - name: create target directory in container
      file:
        path: /target
        state: directory

    - name: copy a file into the container
      copy:
        src: example.file
        dest: /target/example.file
