it is also possible to use this ansible module docker_container_copy_into module

usage e.g. from the doc,

- name: Copy a file into the container
  community.docker.docker_container_copy_into:
    container: mydata
    path: /home/user/data.txt
    container_path: /data/input.txt

I assume you are using a plain Docker container without an orchestrated solution (such as Kubernetes or Swarm). If your container is already running, that will depend:

Without volume mounted

If you want to copy the file into an existing container which does not have a volume mounted where you want your file to be copied, I see no other way but running a docker cp command via shell or command, for example:

- name: Copy file into existing container at /path/in/the/container/kapaci
  shell: docker cp /etc/kapacitor/kapaci tick_kapacitor:/path/in/the/container/kapaci

With a volume mounted in the container

If you already have a volume mounted from the machine into the container, you can copy the file directly at the machine mount point. For example, if the container has a volume mounted from /var/myapp/data to /path/in/the/container, you can use template to copy the file directly into the container with its mounted volume:

name: kapacitor conf 
template: 
  src: /home/debian/roles/tick_install/files/kapacitor.conf
  dest: /var/myapp/data/kapacitor.conf
  # will be available in container at /path/in/the/container

Running a new container

If you want to runner a new container, you can use the docker_container module or run a command (docker run, docker-compose up......) which will run your container and then copy the file into it using one of the previously mentionned solution.
