Keeping secrets separate from an image or pod is essential primarily to prevent exposure of sensitive data. When secrets, such as API keys, passwords, or other confidential credentials, are embedded within the image or pod, there is a significant risk of unintentional exposure. This exposure could occur if the image is shared publicly or if logs are improperly managed, leading to potential security vulnerabilities.

By managing secrets independently, organizations can implement more robust security practices. For instance, they can use tools like Kubernetes Secrets, HashiCorp Vault, or environment variables specifically designed to handle sensitive information securely. This ensures that sensitive data is accessed only by authorized services and that it can be rotated or revoked without needing to rebuild and redeploy images.

While optimal performance, scaling, and easier updates are important considerations in software deployment, they are not as critical as the need to protect sensitive information from unauthorized access. Keeping sensitive data separate mitigates risks and aligns with industry best practices for security and compliance.
