How to Handle Secrets in Helm

Kubernetes (K8s), an open-source container orchestration system, has become the de-facto standard for running containerized workloads thanks to its scalability and resilience.

Although K8s has the capabilities to streamline deployment processes, the actual deployment of applications can be cumbersome, since deploying an app to a K8s cluster typically involves managing multiple K8s manifests (like Deployment, Service, ConfigMap, Secret, Ingress, etc.) in YAML format. This isn't ideal because it introduces additional operational overhead due to the increased number of files for one app. Moreover, it often leads to duplicated, copy-pasted sections of the same app across different environments, making it more susceptible to human errors.
