# Passing Configs and Secrets

Configuration and Secret management in Azure

There are many ways to pass configurations to containers at run-time. Although simple to set up, using Environmental Variables can become complex if there are too many configurations, especially files and certificates. In Kubernetes, you also have the option to populate environment variables from [Config Maps](/docs/automation-platform/kubernetes-overview/configs-and-secrets/mounting-config-as-files.md#creating-a-kubernetes-configmap) or [Secrets](/docs/automation-platform/kubernetes-overview/configs-and-secrets/setting-kubernetes-secrets.md#setting-kubernetes-secrets).

There are several methods for passing configurations to containers during runtime:.

1. **Environment Variables**: A simple method for passing configuration data, but it can become cumbersome when dealing with many configurations or sensitive data like certificates and keys.
2. **ConfigMaps and Secrets in Kubernetes**: For more structured management of configuration data, Kubernetes offers ConfigMaps for non-sensitive data and Secrets for sensitive data (e.g., passwords, tokens). These can be injected into containers at runtime, providing a cleaner and more secure way to manage configurations.

3. **Azure Key Vault**: For Azure users, **Azure Key Vault** is an option to securely store and manage sensitive configurations and secrets outside of your application, reducing the complexity of handling sensitive data.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.duplocloud.com/docs/automation-platform/overview-2/azure-services/containers-and-services/passing-config-and-secrets.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
