A Secret can be referenced as a container environment variable by defining it in the container's configuration. This process involves specifying the secret’s key in the environment variable section of the container definition within the workload manifest, such as a deployment or pod specification. When the pod is created, Kubernetes injects the secret data as environment variables into the running container, enabling applications to access sensitive information securely without exposing it in plaintext. This method of referencing secrets promotes security and simplifies configuration management, allowing developers to manage their sensitive data more effectively and minimizing hardcoding sensitive information directly into the application code or configuration files.
