In this thrilling sequel, we embark on a captivating exploration of Configu—an open-source implementation of Configuration as Code (CaC) for application configuration management. Prepare yourselves for a wild ride as we uncover how Configu tackles the challenges of handling complex configurations, revolutionizes development workflows, and becomes the superhero of configuration management. So hold on tight and brace yourself for another exciting tech adventure!
Background: Unveiling Application Configurations
Before we delve into the magic of Configu, let's take a moment to revisit the importance of application configurations. In the software development lifecycle, configurations—those precious bits of metadata—are extracted from code and managed separately to customize application behavior across different deployments and environments. Configurations are the secret sauce that adds flavor and adaptability to our applications. Configu recognizes their significance and sets out to streamline their management and collaboration, putting the power back in the hands of developers.
The Motivation behind Configu: Addressing the Configuration Struggle
As our codebase grows, so does the complexity of our configuration needs. Yet, managing configurations in today's reality can be a formidable challenge. Configuration data is scattered across various systems, files, databases, and even third-party systems, often resembling a confounding labyrinth. This fragmented approach leads to bottlenecks, manual errors, and missed opportunities for automation and collaboration. Outdated or incorrect configurations can result in bugs, downtime, and even worse—an angry horde of users storming your virtual gates! Configu rides in on a mission to simplify configuration management, ensuring stability, reliability, and empowering development teams to conquer the configuration chaos.
Configu Main Concepts: Unraveling the Configuration Flow
Now, let's unravel the inner workings of Configu and shed light on its key concepts, seamlessly intertwined to optimize the configuration flow:
Config: The Genetic Blueprint:
At the core of Configu lies the Config—a fundamental data model that defines the essence of your application's behavior. It's like the DNA strand that shapes and guides your software. Each Config carries a unique identifier (key), a context (set), and the actual configuration value. Think of it as your application's genetic blueprint, ready to be brought to life.
ConfigStore: Versatile Storage Engine:
Configs find their home in the ConfigStore—a dynamic storage engine that adapts to different systems and services. Whether it's a database, file, secret manager, or even a custom-made solution, the ConfigStore stands tall as the fortress that guards your configurations. It offers flexibility, scalability, and enough magic to make even the most eccentric configurations feel right at home.
ConfigSchema: Declaring the Genetic Code:
The ConfigSchema plays a crucial role in Configu's configuration orchestration. This special file, adorned with the .cfgu extension, declares the genetic code of your application. It establishes the bindings between Config keys and their respective Cfgu declarations, specifying characteristics, and constraints for each value. With ConfigSchema, your configurations adhere to a predefined structure, ensuring harmony and consistency in the configuration universe.
.cfgu.json
{
"LOG_LEVEL": {
"type": "RegEx",
"pattern": "^(debug|info|warn|error)$",
"default": "info",
"required": true,
"description": "Represents the severity of the log events passed to the stdout"
}
}
Configu Interfaces: Orchestrating the Configuration Symphony:
Configu interfaces are the maestros orchestrating the symphony of configurations. Through unified APIs like the Configu SDKs and the Configu CLI, developers wield the power to effortlessly interact with configuration data. Fetch, set, transform, and inject configurations with the grace of a seasoned conductor. These interfaces bridge the gap between developers and the ConfigStore, granting them full command over their application's behavior.
Storing Configs: Activating the ConfigStore:
When Configs are stored, the Configu interfaces connect to the ConfigStore and unleash its mighty set method. Configs find solace in the ConfigStore's memory, snug and secure, awaiting their call to action. This meticulous process ensures your configurations are safely stored, ready to rise when the time is right.
configu upsert --store 'configu' --set 'development' --schema './.cfgu.json' -c 'LOG_LEVEL=debug'
configu upsert --store 'configu' --set 'production' --schema './.cfgu.json' -c 'LOG_LEVEL=error'
configu upsert --store 'configu' --set 'production/tenant' --schema './.cfgu.json' -c 'LOG_LEVEL=warn'
Fetching Configs: Unleashing the Configuration Magic:
During build, deployment, or runtime, Configu interfaces spring into action, summoning configurations from the ConfigStore. By activating the get method, relevant Configs are retrieved based on context and schema, like a magical conjuration tailored to your needs. These configurations can then be transformed into powerful artifacts or injected seamlessly into your software's processes. Behold the true magic of Configu—the ability to harness the perfect configuration spells at the right time and place.
configu eval --store 'configu' --set 'development' --schema './.cfgu.json' | configu export --run 'node server.js'
configu eval --store 'configu' --set 'production' --schema './.cfgu.json' | configu export --format 'HelmValues' > ./values.yaml
Bulk Fetching: Streamlining the Configuration Flow:
To streamline the process and make configuration retrieval a breeze, Configu offers the option of bulk fetching. It's like summoning an army of configurations to fulfill your application's needs, all with a flick of a wand. No more painstakingly fetching one configuration at a time. With bulk fetching, unleash the full power of Configu and let it rain configurations upon your software.
configu eval ... | configu eval ... | configu export ...
Configu's "How": Implementing the Features and Principles of CaC
Now that we've untangled the configuration flow, let's witness how Configu embraces the core features and principles of Configuration as Code:
Consistency and Reproducibility:
Configu ensures consistency and reproducibility by treating configurations as code. Configs, residing in the ConfigStore, retain their context and value, guaranteeing consistent behavior across different environments. Say goodbye to unpredictable configurations and hello to harmony and stability!
Versioning and Tracking:
With Configu, bid farewell to configuration confusion. By including the ConfigSchema in your version control system alongside your code, changes to configurations are recorded and tracked. This historical record empowers you to roll back to previous versions with ease. It's like having a time machine for your configurations, traveling back to any desired state of your application.
Automation and Efficiency:
Configu embraces automation and efficiency with open arms. Configu interfaces allow developers to automate configuration processes. Whether you're using the Configu CLI during build and deployment or the Configu SDK at runtime, fetching, transforming, and injecting configurations becomes a breeze. Say goodbye to manual effort and hello to automated brilliance. Let Configu handle the heavy lifting while you sit back and enjoy the show!
Scalability and Agility:
Configu's flexible architecture and hierarchical ConfigSets empower you to scale and adapt effortlessly. No limits, no boundaries—organize your .cfgu files to suit your needs and workflow.

Looks amazing! I wish I had Configu back when I was working on multiple simultaneous projects at the same time to help keep all the configurations organized between all the different environments we had to manage.
This is really interesting. Can I use other products to store my configurations with Configu (e.g., Git repository or Hashicorp Vault)?
Of course! Configu orchestrator is open-source software and supports many different storage options including ASM, Hashicorp Vault and even files in a git repository.
You can also create your own store for your benefit and others.

Great article, thanks for sharing.
I'm really curious about Configu now. I'm drowning in .env files at work with duplicates and annoying comments all over.
