# 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"`. |
