# Python Images

## Running Jobs

<table><thead><tr><th width="317">Package</th><th>Definition</th></tr></thead><tbody><tr><td>py-dynamic:dynamic</td><td>Base container for Python based jobs, installing a given Python library and running a specific module on start-up</td></tr><tr><td>py-dynamic:dynamic-media</td><td>Dynamic container with additional dependencies (e.g. ffmpeg) installed for py-media operations</td></tr><tr><td>py-dynamic:dynamic-java</td><td>Dynamic container with JDK installed for Java dependent operations (e.g. Spark)</td></tr><tr><td>py-dynamic:dynamic-java-hadoop</td><td>Dynamic container with Hadoop installed for file system dependent operations</td></tr></tbody></table>

{% hint style="info" %}
Additional versions of images are also applicable, combining media, java and hadoop (e.g. py-dynamic:dynamic-media-java-hadoop).
{% endhint %}

These images are accessible from "rierino-open" Docker repository and have the following environment variables used in their default command:

| Variable             | Description                                                                   | Example                           |
| -------------------- | ----------------------------------------------------------------------------- | --------------------------------- |
| GITHUB\_USER         | GitHub user to use for accessing Rierino Python packages                      | -                                 |
| GITHUB\_AUTH\_TOKEN  | GitHub token to use for accessing Rierino Python packages                     | -                                 |
| PY\_REPO             | Repository for loading main Rierino Python module                             | rierino-open/py-runner            |
| PY\_RIERINO\_VERSION | Version of main Rierino Python module to load                                 | 0.1.1                             |
| PY\_SCRIPT           | Additional script to execute (e.g. for loading extra libraries)               | /app/config/script.sh             |
| PY\_MAIN\_MODULE     | Main module & arguments to pas on to main Rierino Python module for execution | rierino\_util.Runner --base64 XXX |

{% hint style="info" %}
These environment variables are configured through Helm Chart parameters when the image is deployed using [Batch Charts](/installation/artifacts/helm-charts/batch-charts.md).
{% endhint %}

## Loader Jobs

<table><thead><tr><th width="317">Package</th><th>Definition</th></tr></thead><tbody><tr><td>py-loader:loader</td><td>Base container for Python based deployment assets loader, used during initial installations and version upgrades</td></tr><tr><td>py-loader:loader-core-train</td><td>Loader container with core and training deployment assets pre-downloaded</td></tr></tbody></table>

These images are accessible from "rierino-open" Docker repository and are typically used with Helm Charts during installation and version upgrades.
