What I am trying to do:  
Create a docker image so that I can use docker to run playbooks.

What my problem is:  
Ansible cannot find the executable for the ansible.posix.synchronize module I am using in my playbook. Note, I have confirmed the module exists by running  
ansible-galaxy collection list

Error:

```auto

```

Here is how my docker image is defined:

```auto
FROM ubuntu:latest

RUN apt-get update

RUN apt-get install -y python3

RUN apt-get install -y python3-pip

RUN apt install -y openssh-client

RUN apt install -y sshpass

RUN apt install -y python3 ansible

```

here is how my playbook is configured:

```auto
- name: fakedagdeployment
  hosts: airflowdev
  become: true
  tasks:
    - name: deploy fake dags
      ansible.posix.synchronize:
        src: /fake_dags
        dest: /home/infogrid/cp_test_ansible
        delete: true
        recursive: true

```

Here is my docker compose file:

```auto

services:
  ansible_poc:
    container_name: marios_spaghetti
    environment:
      ANSIBLE_HOST_KEY_CHECKING: False
    image: ansible-poc
    command: ansible-playbook -vvv -i ./inventory/hosts.yml --user infogrid ./playbooks/fakedagdeploy.yml
    volumes:
      - ./fake_dags:/fake_dags
      - ./inventory:/inventory
      - ./playbooks:/playbooks

```

Thank you for your help!

You are missing `rsync`:

```auto
marios_spaghetti | "msg": "Failed to find required executable \"rsync\" in paths: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

```

Thanks, I made the assumption rsync was installed and it is not I solved the issue by adding this line to my image code

RUN apt-get install -y rsync

I’d suggest the comment above from @sivel should be the solution, currently the comment that is marked as the solution appears to have been [copied from a StackOverflow comment](https://stackoverflow.com/q/79398282/9669328)…

Yep! I created that post 🙂 That’s why 🙂 but I am happy to edit and mark his as the solution. I just wanted to make sure the code to add to the image is explicitly called out.
