Secure Configuration
Securely store configuration data using Kubernetes Secrets
Intent & Description
The Secure Configuration pattern uses Kubernetes Secrets to securely store sensitive configuration data like passwords, API keys, and certificates. Secrets are encoded at rest and can be mounted as files or exposed as environment variables. This prevents sensitive data from being stored in plain text in ConfigMaps or application code.
Real-world Use Case
Use when you need to store sensitive configuration data or when you want to prevent secrets from being exposed in plain text.
