Kubernetes ConfigMaps and Secrets are key objects for storing configuration data securely, decoupling environment-specific configuration from container images to make it easier to move applications. ConfigMaps store configuration data as key-value pairs, mainly used to configure settings for containers running in a pod in the same namespace, while Secrets contain sensitive data such as passwords, tokens, or keys. CAST AI's security report scans clusters for potential vulnerabilities, compares its state against industry best practices, and suggests ways to secure it optimally, reducing the risk of exposing cluster data by decoupling application code and configurations.
