  This blog post details a method for securely deploying applications to on-premises IIS servers from Azure Pipelines without exposing credentials. The author leverages a self-hosted agent running on the target server, combined with a pre-configured deployment group. Instead of storing sensitive information directly in the pipeline, the approach uses Azure Key Vault to securely store the application pool password. The pipeline then retrieves this password during the deployment process and utilizes it with the powershell task in Azure Pipelines to update the application pool, ensuring credentials are not exposed in plain text within the pipeline or agent's environment. This setup enables automated deployments while mitigating the security risks associated with managing credentials for on-premises deployments.

  This blog post details a method for implementing reasonably secure deployments from Azure Pipelines to on-premises IIS servers, focusing on minimizing the attack surface and adhering to the principle of least privilege. The author outlines a process that avoids storing sensitive credentials like passwords directly within the pipeline definition, leveraging Azure Key Vault for secure secret management and Managed Identities for authentication.

  The core strategy revolves around establishing a dedicated deployment user account on the target IIS server. This account is granted only the necessary permissions to deploy and manage the specific application, adhering to the principle of least privilege. It explicitly does not have administrative privileges. This minimizes the potential damage if the account is compromised.

  The deployment process utilizes a self-hosted agent running on the on-premises server, which is registered with the Azure DevOps project. Critically, the agent itself doesn't hold any secrets. Instead, it leverages a Managed Identity assigned to the Azure DevOps project. This Managed Identity has permissions to access the necessary secrets stored in Azure Key Vault. During the deployment process, the pipeline instructs the agent to retrieve the deployment user's credentials from Key Vault using its Managed Identity. These credentials are then used to authenticate with the IIS server and perform the deployment tasks.

  The actual deployment steps involve using the msdeploy.exe utility. The retrieved credentials are passed securely to msdeploy.exe to authenticate with the target IIS server. The pipeline script then uses msdeploy.exe to sync the application files from the build artifact to the IIS server and configure the application within IIS. The author emphasizes the importance of using the -declareParamFile option with msdeploy.exe to avoid exposing sensitive information in the pipeline logs. This approach stores the sensitive deployment parameters in a separate file that is accessed securely during the deployment process.

  The author also touches on securing the web.config file. They recommend excluding the web.config from the initial deployment and instead using a separate, dedicated step to deploy a transformed web.config file. This transformed configuration file contains environment-specific settings retrieved securely from Azure Key Vault, ensuring sensitive information like connection strings isn't embedded in the application's source code. This approach separates configuration from code and allows for environment-specific configurations without compromising security.

  Finally, the post briefly discusses the option of using deployment groups as an alternative to individual self-hosted agents. However, the core principles of using Managed Identities, Azure Key Vault, and least privilege remain the same regardless of the chosen deployment method. The author advocates for this approach as a more secure and manageable way to handle deployments to on-premises IIS servers compared to traditional methods relying on stored credentials.

  Verbose tl;dr

  Yoke aims to simplify Kubernetes deployments by managing infrastructure as code within the Kubernetes cluster itself. It leverages a GitOps approach, using a dedicated controller to synchronize the desired state from a Git repository directly to the cluster. This eliminates the external dependencies and complex tooling often associated with traditional Infrastructure as Code solutions, making deployments more streamlined and self-contained within the Kubernetes ecosystem. Yoke supports multiple cloud providers and offers features like diff previews and automated rollouts for improved control and visibility. This approach keeps the entire deployment process within the familiar Kubernetes context, simplifying management and reducing the operational overhead of infrastructure provisioning and updates.

  The blog post "Yoke: Infrastructure as Code, but actually" by xeiaso explores the author's dissatisfaction with existing Infrastructure as Code (IaC) tools, particularly in the context of Kubernetes, and introduces their own solution, Yoke. The author argues that current IaC tools, while helpful for initial setup, often fall short in maintaining and updating complex deployments over time. They find that these tools can create a disconnect between the declared state and the actual state of the system, leading to drift and difficulties in troubleshooting. This divergence stems from factors such as implicit dependencies, external modifications, and the complexities of stateful applications within Kubernetes.

  Xeiaso posits that the fundamental problem lies in the imperative nature of many IaC operations. They contend that relying on a series of commands to transition between states creates opportunities for errors and discrepancies. Instead, Yoke adopts a declarative model focused on the desired end state. Yoke achieves this through a unique approach of generating Kubernetes manifests dynamically, based on a concise configuration file. This dynamic generation, powered by the Dhall language, allows for flexibility and programmatic control over the infrastructure.

  A key feature of Yoke highlighted in the post is its ability to manage secrets effectively. The author explains how Yoke leverages SOPS, a tool for encrypting secrets, to ensure security while maintaining a declarative workflow. This integration streamlines the process of managing sensitive information within the Kubernetes cluster.

  Furthermore, the blog post emphasizes Yoke's ease of use and maintainability. The author illustrates how Yoke simplifies complex tasks, such as rolling updates and scaling deployments, through its declarative configuration. This reduces the cognitive load on the operator and minimizes the potential for human error. The author also underscores the importance of testability in IaC and describes how Yoke's design facilitates thorough testing of infrastructure changes before deployment.

  Finally, the author concludes by expressing their hope that Yoke will provide a more robust and reliable approach to managing Kubernetes infrastructure, ultimately addressing the shortcomings they have experienced with existing IaC solutions. They present Yoke as a tool that bridges the gap between the desired and actual state, offering a truly declarative and maintainable infrastructure management experience.

• It's OK to hardcode feature flags

  permalink

  Posted: 2025-02-01 16:54:17

  Verbose tl;dr

  Hardcoding feature flags, particularly for kill switches or short-lived A/B tests, is often a pragmatic and acceptable approach. While dynamic feature flag management systems offer flexibility, they introduce complexity and potential points of failure. For simple scenarios, the overhead of a dedicated system can outweigh the benefits. Directly embedding feature flags in the code allows for quicker implementation, easier understanding, and improved performance, especially when the flag's lifespan is short or its purpose highly specific. This simplicity can make code cleaner and easier to maintain in the long run, as opposed to relying on external dependencies that may eventually become obsolete.

  The blog post, titled "It's OK to hardcode feature flags," argues against the prevailing wisdom that feature flags should always be managed through a dedicated service or configuration file. The author, Mendhak, posits that for certain types of feature flags, specifically those tied to permanent features intended to eventually become a standard part of the application, hardcoding them directly into the codebase can be a more efficient and less complex approach.

  Mendhak begins by acknowledging the common use cases for feature flag management systems: A/B testing, canary releases, and kill switches. These scenarios require dynamic control over features, enabling rapid activation, deactivation, or modification without requiring a new deployment. However, the author contends that not all feature flags fit this mold. Some features are developed with the explicit intention of being permanently enabled once they are deemed stable and ready. For these "permanent" feature flags, using a complex management system introduces unnecessary overhead and complexity.

  The argument centers on the idea that maintaining a feature flag within a separate system creates ongoing maintenance burden and increases the cognitive load for developers. Developers must remember to eventually remove the flag and its associated logic from both the codebase and the feature flag system, a task that can easily be overlooked. Hardcoding the flag, on the other hand, allows for a simpler, more self-documenting approach. When the feature is ready to be permanently enabled, the flag and its conditional logic can be directly removed from the code, leaving no lingering remnants in external systems. This simplification reduces the risk of errors, improves code readability, and streamlines the development process.

  Mendhak suggests a specific approach for hardcoding these permanent feature flags: Use a simple boolean variable within the codebase, initialized to false. When the feature is ready, change the variable to true and deploy the updated code. Once the feature has been live and confirmed stable for a sufficient period, the flag and its associated conditional code can be removed entirely. This process avoids the complexities of external dependencies and keeps the feature's lifecycle entirely within the codebase itself.

  The author emphasizes that this approach is not suitable for all feature flags. Dynamic feature flags, like those used for A/B testing, still benefit from dedicated management systems. However, for features destined to become standard components of the application, hardcoding provides a cleaner, more efficient, and less error-prone alternative. This targeted use of hardcoded flags reduces the overall complexity of the system, simplifying maintenance and improving code clarity in the long run.

  Hacker News users generally agree with the author's premise that hardcoding feature flags for small, non-A/B tested features is acceptable. Several commenters emphasize the importance of cleaning up technical debt by removing these flags once the feature is fully launched. Some suggest using tools or techniques to automate this process or integrate it into the development workflow. A few caution against overuse for complex or long-term features where a more robust feature flag management system would be beneficial. Others discuss specific implementation details, like using enums or constants, and the importance of clear naming conventions for clarity and maintainability. A recurring sentiment is that the complexity of feature flag management should be proportional to the complexity and longevity of the feature itself.

  The Hacker News post "It's OK to hardcode feature flags" generated a moderate amount of discussion, with several commenters offering their perspectives on the practice.

  One of the most compelling threads explored the nuances of "hardcoding" and its implications for different contexts. Some argued that true hardcoding, where a feature flag is permanently embedded in the code with no easy way to change it without recompilation and redeployment, is indeed problematic and should be avoided. They emphasized that the value of feature flags comes from their flexibility and ability to toggle functionality without new releases. However, others pointed out that the article's usage of "hardcoding" might refer to situations where the flag's value is set during the build process or initialized at runtime, rather than being truly immutable. This type of "hardcoding" could be acceptable, especially for features that are intended to be permanently enabled or disabled for specific builds or environments (e.g., demo versions, A/B testing). This distinction between permanently embedding a value and setting it during build/initialization was a key point of discussion.

  Another commenter highlighted the importance of considering the feature's lifespan. For short-lived features, hardcoding (especially in the sense of setting the value at build time) might be acceptable, as the code will likely be removed or refactored soon anyway. However, for long-lived features, a more robust and dynamic approach to feature flagging is generally preferred.

  A recurring theme was the balance between pragmatism and best practices. Several commenters acknowledged that while ideally feature flags should be managed through a dedicated system, practical constraints, such as limited resources or tight deadlines, can sometimes justify simpler, hardcoded approaches. One comment even suggested that for small projects or teams, the overhead of a feature flag management system might outweigh its benefits.

  Some users shared their personal experiences and preferences, some advocating for build-time configuration as a sensible middle ground, allowing for customized builds without sacrificing the ability to permanently enable or disable features for different deployments. Others cautioned against overusing feature flags, suggesting that they should be primarily employed for major features or risky changes, not for every minor tweak.

  While there wasn't overwhelming consensus on the absolute right or wrong way to handle feature flags, the discussion provided a valuable exploration of the trade-offs involved, highlighting the importance of context, feature lifespan, and resource constraints in making informed decisions.
