They exist outside the application code and can be used to set up operational parameters without altering the application's source code. Environment variables allow developers to toggle between different configurations easily, such as switching from development to production settings. In PHP, environment variables are often used to store sensitive information such as database credentials, API keys, or other configuration parameters. However, it’s important to note that while environment variables are more secure than hard-coding secrets, they are still stored in plaintext and visible to anyone accessing your systems. This makes it critical to use additional mechanisms, like configuration and secrets management systems, to secure confidential info. Why Use Environment Variables in PHP Applications  Environment variables offer several advantages when managing PHP applications, particularly in dynamic and multi-environment setups: Security: Storing sensitive data like database credentials, API keys, and authentication tokens in environment variables is better than hardcoding them in source files, reducing exposure risks. However, environment variables are not fully secure, making it important to use configuration and secrets management systems. Configuration flexibility: Developers can switch between environments (development, staging, production) without modifying the application's code. This makes deployments more efficient and reduces errors. Version control safety: Keeping sensitive configuration data outside the codebase ensures that credentials and secrets are not accidentally committed to version control systems like Git. Simplified deployment: Environment variables help configure applications consistently across different... --- ### Setting Env Variables in Windows, Linux & MacOS: Beginner’s Guide > Environment variables are key-value pairs used by the operating system to configure settings and manage the environment for applications running on a computer. - Published: 2025-03-13 - Modified: 2025-03-13 - URL: https://configu.com/blog/setting-env-variables-in-windows-linux-macos-beginners-guide/ - Categories: Technical Guides - Tags: environment variables What Are Environment Variables?   Environment variables are key-value pairs used by the operating system to configure settings and manage the environment for applications running on a computer. These variables influence the behavior of software without changing its source code. They store system-wide values such as directory paths, system settings, or application configurations, allowing applications to function in various environments without modification. Typically prefixed with names (e. g. , PATH, HOME), environment variables are adjusted at different levels like the user or system level, making them versatile for software deployment. They are integral to scripts and batch processes that automate tasks.   Developers and system administrators widely use these variables to reduce configuration errors and improve the adaptability of systems across environments. The Importance of Environment Variables in System Configuration  Environment variables aid in system configuration by providing a centralized way to manage settings that affect applications and services. They eliminate the need to hardcode values in scripts or programs, making software deployment more flexible and maintainable. One key benefit is portability. By defining environment variables, applications can run across different environments—development, testing, and production—without requiring code changes. This ensures consistency and reduces the risk of misconfigurations. Security is another advantage. Sensitive information such as API keys, database credentials, and authentication tokens can be stored as environment variables instead of being embedded in source code, reducing exposure risks. Additionally, environment variables enable automation. System administrators and DevOps teams use them in scripts, cron jobs, and configuration management tools to dynamically... --- ### Site Reliability Engineering: Complete 2025 Guide > Site reliability engineering (SRE) is a discipline that incorporates aspects of software engineering and applies them to infrastructure and operational problems. - Published: 2025-03-13 - Modified: 2025-03-13 - URL: https://configu.com/blog/site-reliability-engineering-complete-guide/ - Categories: Technical Guides - Tags: site reliability engineering What Is Site Reliability Engineering?   Site reliability engineering (SRE) is a discipline that incorporates aspects of software engineering and applies them to infrastructure and operational problems. The main goals are to create scalable and reliable software systems. By integrating software development practices into operations, SRE aims to fill the gaps within traditional operations roles. This approach allows engineers to handle their operational needs while minimizing system downtime. SRE emphasizes automation and the use of metrics to manage system performance, reducing the need for manual intervention. Originally developed at Google, SRE is centered around the concept that the same people who build software should also be responsible for its reliability in production.

This is part of a series of articles about configuration management Anatomy of a Configuration File  Basic Structure and Components At its core, a configuration file is a text file that follows a specific structure. This structure varies based on the language the file is written in, but there are some... --- ### Managing Environment Variables With dotenv > Dotenv is a zero-dependency library or module that loads environment variables from a .env file for easier management. - Published: 2023-11-07 - Modified: 2025-01-17 - URL: https://configu.com/blog/dotenv-managing-environment-variables-in-node-python-php-and-more/ - Categories: Technical Guides - Tags: dotenv What Is dotenv?   Dotenv is a zero-dependency library or module that exists in most programming languages, which loads environment variables from a . env file for easier management. With Dotenv, you can have a dedicated file where you store all your environment variables, and then they get automatically loaded into the runtime environment. For example, if you are working with Node. js, the . env file will be converted into process. env, which is a global object that provides access to all available environment variables.   You don't have to make any changes to your code to start using Dotenv. You install the module (if not built into your programming language), create a . env file, specify your environment variables in this file, and Dotenv handles the rest. You can then access these variables anywhere in your code through the dedicated file. An important point about Dotenv is that it doesn't overwrite existing environment variables. This means that if you have an environment variable that's already defined in your system, Dotenv won't touch it. This is particularly useful when you're working with sensitive data like API keys or database credentials that you don't want to expose in your code. This is part of an extensive series of guides about software development. Why Use dotenv?   Here are a few benefits of using a Dotenv module or library in your programming language of choice: Centralized configuration management: Dotenv centralizes your configuration management into one file. Without Dotenv, you'd have to... --- ### How to Use Github Actions Environment Variables > GitHub Actions is CI/CD platform that automates development pipelines, from the build stage through to testing and deployment. - Published: 2023-11-01 - Modified: 2025-01-17 - URL: https://configu.com/blog/github-actions-environment-variables-uses-types-and-tutorial/ - Categories: Technical Guides - Tags: environment variables What Are Github Actions Environment Variables?   GitHub Actions is a continuous integration and continuous delivery (CI/CD) platform that automates development pipelines, from the build stage through to testing and deployment.   GitHub Actions organizes pipelines using the concept of workflows. For each workflow, there is a set of default environment variables, and you can declare additional custom variables within your workflow file. Environment variables can be used to store and reference data throughout your workflow. They are usable within the context of a workflow step, a job, or a specific action, and are evaluated on the runner machine executing your workflow. To specify a custom environment variable, you can use the env key in the workflow file. The scope of a variable defined this way is limited to the element where it is declared:  If you want the variable to affect the entire workflow, add the env key at the root level of the workflow file. For a specific job within a workflow, use jobs. . env For a particular step within a job, use jobs. . steps. env Another important type of environment variables is secrets. When you store an environment variable as a secret, GitHub Actions stores it securely, to avoid sensitive information from being compromised by attackers. What You Can Do with Environment Variables in GitHub Actions  Configuring Build Parameters Dynamically When you are building a software application, you often need to adjust certain parameters based on the environment in which the build is running. For... --- ### Next.js Environment Variables: Built-In, Public, and Private > Environment variables allow Next.js developers to store data their application needs to function correctly at runtime. - Published: 2023-11-01 - Modified: 2025-01-17 - URL: https://configu.com/blog/next-js-environment-variables-built-in-public-and-private/ - Categories: Technical Guides - Tags: environment variables What Are Next. js Environment Variables?   Environment variables are dynamic-named values that can impact the way running processes behave on a device.

They are external variables that specify the environment in which the Node. js application runs. These variables, often stored in key-value pairs, can control and influence the behavior of our software in different environments. These environment variables can hold various types of data, such as application configurations, file paths, and API keys. By storing such data in the environment variables, we can alter the behavior of our application without modifying the codebase. Environment variables also help us manage different configurations for a Node. js application in different environments, such as development, testing, and production. Two common ways to manage environment variables in Node. js are by getting and setting values in the process. env object, and using the dotenv library. We explain both methods in more detail below. Common Use Cases for Node Environment Variables  Configuring Different Application Environments One of the most common use cases for Node environment variables is configuring different application environments. In modern software development, an application often runs in various environments, such as development, testing, and production. Each of these environments may require different configurations. For instance, a development environment may use a different database connection string than a production environment. In such cases, Node environment variables come in handy. We can store these configurations in the environment variables, and our application will automatically pick the correct configuration based on the current environment. This approach not only makes... --- ### Environment Variables: How to Use Them and 4 Critical Best Practices > Environment variables are dynamic-named values that can influence the way running processes behave on a computer. - Published: 2023-10-25 - Modified: 2025-01-17 - URL: https://configu.com/blog/environment-variables-how-to-use-them-and-4-critical-best-practices/ - Categories: Technical Guides - Tags: environment variables What Are Environment Variables?   Environment variables are dynamic-named values that can influence the way running processes behave on a computer. They exist in every computer system, and they're used to make the system aware of certain conditions. They can be created, edited, saved, and deleted, and they can be unique to a specific system, user, or application. An environment variable is made up of a name/value pair. The name is an identifier that is used to call the value in a variety of functions and programs. The value, on the other hand, is the information associated with the variable. This information can be a directory path, a filename, a computer name, or any other type of data. Environment variables can change as the conditions in the system change. This can be due to changes made by the user, changes made by installed applications, or changes made by the system itself. In the first part of this article, we’ll provide practical info on setting and working with environment variables in common operating systems and framework. In the second part, we’ll discuss broader considerations—why you should use environment variables, common use cases, options for storing them, and best practices.

They are part of the environment in which a process runs. For example, a running process can query the value of the HOME environment variable to get the path to the main directory used by the process. Docker uses environment variables to customize your Docker containers and applications without having to modify your Dockerfiles or container images. In Docker, environment variables can be used to pass configuration settings and other information into Docker containers at runtime.   Environment variables can be defined in your Dockerfile using the ENV command, or they can be passed into your containers at the command line when you run your containers using the -e option. Once an environment variable has been set, it can be used in your Dockerfile and your application code to dynamically configure your container and application behavior. Common Use Cases for Docker Environment Variables  Configuring Software Packages Inside Containers Many software packages are configured using environment variables, and Docker makes it easy to pass these variables into your containers at runtime. For example, you might have a Docker container that runs a web server like Apache or Nginx. You can use Docker environment variables to configure the server's settings, such as the server name, the port it listens on, and the root directory for your website. This allows you to have a single Docker image that can be configured... --- ### Leveraging Environment Variables in Python Programming > Explore the role and management of Python environment variables for optimizing software processes and configuration in our detailed guide. - Published: 2023-09-27 - Modified: 2025-01-17 - URL: https://configu.com/blog/working-with-python-environment-variables-and-5-best-practices-you-should-know/ - Categories: Technical Guides - Tags: environment variables What Are Python Environment Variables?   Python environment variables are dynamic named values that can change the way running processes behave on a computer. They are part of the environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the HOME or USERPROFILE variable to find the directory structure owned by the user running the process. Environment variables provide a simple way to share configuration settings between multiple applications and processes in Linux. Python, like other languages, provides a straightforward way to interact with these environment variables via the os module. Common Use Cases for Environment Variables in Python  Here are a few ways you might use environment variables in your Python programs. Application Configuration Another common use of environment variables is application configuration. You might want to have different settings for your development, staging, and production environments. Rather than hardcoding these settings into your application, you can use environment variables to dynamically apply these configurations based on the current environment. Learn more in our detailed guide to Python environment variables Dynamic Resource Pointers Environment variables can also be used as dynamic resource pointers. This means that you can use them to point to resources that your application needs to interact with, such as API URLs, service endpoints, or file paths.

In other words, it’s about treating configuration data just like we treat application code. The adoption of CaC offers numerous benefits, including consistency, repeatability, and faster recovery from failures. It reduces the possibility of human error in configuration management, leading to higher reliability. Moreover, since configuration is managed as code, it can be version controlled, enabling easy tracking of changes and rollback if necessary. Configuration-as-Code vs. Infrastructure as Code  Infrastructure as Code (IaC) is about automating the provisioning of infrastructure, which includes servers, databases, networks, and other hardware or software components.   Configuration-as-Code (CaC) is about managing the settings and parameters that an application or system component needs to function correctly. For instance, an IaC script might set up a server, install a database on it, and configure network settings. A CaC script, in contrast, would specify the database's name, the tables it should include, and the network ports it should listen to. Thus, while both practices are essential for automation and repeatability in software development, they address different layers of the system. Related content: Managing Environment Variables with Dotenv Core Principles of Configuration-as-Code  1. Idempotency In the context of CaC, idempotency means that no matter how many times you apply a configuration, the outcome will be the same.

It is a discipline applying technical and administrative direction throughout the product lifecycle to establish technical baselines and make it possible to implement, monitor, and control changes. Configuration management can be viewed as the "big picture" view of a system. It not only covers the individual components but also how they interrelate and depend on each other. The process of configuration management includes the identification of the configuration items (CIs) that make up the IT environment, control of the CIs and their changes, and recording and reporting on the status of the CIs and their changes. Traditionally, configuration management was an “IT thing”, used by IT teams to manage changes to critical infrastructure like servers and network equipment. While IT configuration management is still important, the new frontier of CM is the world of software engineering. Software configuration management is a critical part of the software development life cycle (SDLC), yet in many organizations, it is not well understood, and not properly managed, if at all.   In this article, we’ll explain the basics of configuration management (which apply both to IT and software engineering), and then explore how CM works in the software world and how you can turn software configurations from a risk to a competitive advantage. This is part of an... --- ### Video: First Steps with Configu > Learn how to simplify configuration management with Configu open-source software and cloud platform and the configuration-as-code approach. - Published: 2023-07-27 - Modified: 2024-12-27 - URL: https://configu.com/blog/video-first-steps-with-configu/ - Categories: Company News In this latest video, we demonstrate how to get started and simplify your configuration management using the Configu open-source software and cloud platform.

One critical aspect often overlooked is the security of application configurations. Unauthorized access to configuration files can expose sensitive data and compromise the integrity of an entire system.   In this blog post, we dive into the challenges associated with configuration management and explore the solution: authorization over configurations. By understanding the problem and implementing effective authorization mechanisms, we can strengthen our applications against security vulnerabilities. The Significance of Authorization Over Configurations Imagine a scenario where a misconfigured database credential or an exposed API key leads to a major data breach or service disruption. The consequences could be severe, resulting in financial loss, reputational damage, and compromised customer trust. Unauthorized access to configurations can occur through various avenues, such as insecure storage, weak authentication mechanisms, or inadequate access controls. For example, if a database credential is mistakenly stored in a plaintext configuration file or if an API key is inadvertently exposed in a publicly accessible repository, unauthorized individuals or malicious actors can gain access to critical systems, compromising the confidentiality and integrity of the data. The Current State: Where Most Systems Fall Short Most existing systems offer binary authorization over configurations: developers either have full access or none at all. This all-or-nothing approach is restrictive, often making developers overly dependent on DevOps engineers for even minor configuration changes. The lack of granularity in access controls can lead to bottlenecks,... --- ### Unmasking Ghost Parameters, or How to Save Time and Money > Ghost parameters have faded from use in your code but still lurk in your configuration files, draining resources and costing money. Find them - Published: 2023-07-18 - Modified: 2024-12-27 - URL: https://configu.com/blog/unmasking-ghost-parameters-or-how-to-save-time-and-money/ - Categories: Technical Guides Are you haunted by hidden costs in your application configurations? Meet the "ghost parameters" - those feature flags, secrets, and environment variables that have faded from use in your code but still lurk in your configuration files, silently draining resources and costing money as they are stored in the feature flag solution or secret manager, and potentially leading to errors. ? ? ? ? ? ? ? ? ? ? ? ? The Hidden Costs of Ghost Parameters As developers, we're often laser-focused on writing and optimizing code, while the management of application configurations can fall by the wayside. However, these configurations, if not properly tracked and managed, can lead to unnecessary costs and potential errors.   The costs associated with ghost parameters can be twofold. First, there's the direct financial cost. Many management tools charge per parameter stored. This means that every ghost parameter - a feature flag, secret, or environment variable that's no longer used in your code but still exists in your configuration files - is incurring a cost. Over time, and across many parameters, these costs can add up significantly. Second, there's the cost in terms of complexity and potential errors. Each unused or obsolete parameter adds to the clutter in your configuration files, making it harder to understand and manage the configurations that are actually relevant. This increased complexity can slow down development, make troubleshooting more difficult, and increase the risk of errors. For example, a developer might waste time trying to understand the purpose... --- ### Why you should shift from ENV files to Configuration-as-Code > the drawbacks of using environment variables stored in ENV files and why Configuration-as-Code (CaC) is a much stronger approach. - Published: 2023-07-13 - Modified: 2024-12-27 - URL: https://configu.com/blog/why-you-should-shift-from-env-files-to-configuration-as-code/ - Categories: Technical Guides Greetings, fellow developers! Today we're diving into the world of application configuration. We'll discuss the drawbacks of using environment variables stored in ENV files and why Configuration-as-Code (CaC) is a much stronger approach. The Challenge with ENV Files As developers, we often find ourselves managing a vast array of configurations that vary across environments and are stored in multiple systems. This can be a daunting task, involving error-prone, tedious work that hinders DevOps automation and slows down our development process. One common approach that leads to this challenge is the use of environment variables stored in env files. While this method is simple and straightforward, it starts to show its drawbacks as our applications grow and become more complex. According to the Twelve-Factor App methodology, an app's configuration values should be strictly separated from its code and should vary between deploys. The problem with using env files is that they often become too closely linked to the codebase and can be mistakenly checked into version control or become outdated when kept locally. Moreover, as Diogo Mónica pointed out in his article "Why you shouldn't use ENV variables for secret data", environment variables can be easily exposed, either through error messages, debugging, or subprocesses. This can lead to secret data being leaked, posing a significant security risk. The Power of Configuration-as-Code (CaC) So, what's the solution? Enter Configuration-as-Code (CaC). With CaC, we treat application configurations as code. This means we can use the same practices we use for our codebase—like version... --- ### Unleashing the Power of Configuration-as-Code - Published: 2023-06-28 - Modified: 2024-12-27 - URL: https://configu.com/blog/configu-unleashing-the-power-of-configuration-as-code/ - Categories: Technical Guides Welcome back, fellow tech enthusiasts!
