Aquí hay algunas ideas posibles:

* Un "Contenedor de Inicio" en Kubernetes que se ejecuta antes de tu contenedor de aplicación
* Un script de bash que ejecuta los pasos previos y luego inicia tu aplicación
    * Aún necesitarías una forma de iniciar/reiniciar *ese* script de bash, detectar errores, etc.

/// tip | Consejo

Hier sind einige mögliche Ideen:

* Ein „Init-Container“ in Kubernetes, der vor Ihrem Anwendungs-Container ausgeführt wird
* Ein Bash-Skript, das die Vorab-Schritte ausführt und dann Ihre Anwendung startet
    * Sie benötigen immer noch eine Möglichkeit, *dieses* Bash-Skript zu starten/neu zu starten, Fehler zu erkennen, usw.

/// tip | Tipp

Você pode criar e utilizar variáveis de ambiente no terminal, sem precisar utilizar Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Você pode criar uma env var MY_NAME usando
$ export MY_NAME="Wade Wilson"

// E utilizá-la em outros programas, como
$ echo "Hello $MY_NAME"

Hello Wade Wilson

#!/usr/bin/env bash

echo "Running $0"

trap 'catch $LINENO' ERR

		done

     * Inputs are <every possible 10-character string of characters "a./">
     *
     * Expected outputs are generated by the code itself, but they've been
     * checked against the inputs under Bash in order to confirm that the two
     * forms are equivalent (though not necessarily minimal, though we hope this
     * to be the case). Thus, this test is more of a regression test.
     *

Here are some possible ideas:

* An "Init Container" in Kubernetes that runs before your app container
* A bash script that runs the previous steps and then starts your application
    * You would still need a way to start/restart *that* bash script, detect errors, etc.
