Kubernetes ConfigMaps

Developers should use ConfigMaps when deploying applications in Kubernetes to externalize configuration settings, such as database URLs, feature flags, or logging levels, which vary between environments

Pros

• This is crucial for maintaining 12-factor app principles, enabling seamless updates without rebuilding container images, and simplifying configuration management in microservices architectures
• Related to: kubernetes, docker

Cons

• Specific tradeoffs depend on your use case
