+# M1-3-1 Configuration Management
+
+## Ansible Task
+
+Create an Ansible playbook that build, push and then run the Docker image for the Python
+application. Let your playbook has the following variables:
+
+* `image_name` - contains the name of your image without the tag, i.e. `vutoff/python-app`
+* `image_tag` - contains the tag you tagged your image with, i.e. `v0.2`
+* `listen_port` - contains the listening port you're binding your app to.
+
+Make sure that you set environment variable `PORT` when you define your container
+in the Ansible playbook that takes its value from `listen_port` variable.
+
+Use Ansible modules. Do not shell out.
+
+### Requirements
+
+* Make sure you have Python installed. Any version above 3.8 would suffice.
+* The `requirements.txt` file in this directory contains the required Ansible version. Run
+
+```sh
+pip install -r requirements.txt
+```
+
+* Make sure that Docker is running on your local machine.
+
+### Mind the following
+
+* If you're running Docker Desktop or Rancher Desktop, mind the location of the `docker.sock` file. The location of the socket file is
+  * Docker Desktop - `${HOME}/.docker/run/docker.sock`
+  * Rancher DEsktop - ${HOME}/.rd/run/docker.sock
+
+* If you're using one of the above, when you write your Ansible playbook you
+must specify the path to the docker socket with the parameter `docker_host`,
+i.e. `docker_host: "unix://{{ ansible_env.HOME }}/.rd/docker.sock"`.
