Kubernetes Secrets¶

Kubernetes Secrets are objects used to store and manage sensitive information within a Kubernetes cluster. Unlike ConfigMaps, which are typically used for configuration data, Secrets are designed specifically to handle sensitive data such as user passwords, tokens, and certificates^[400-devops__06-Kubernetes__k8s-ithelp__Day16__README.md].

Characteristics¶

While Secrets share many functional characteristics with ConfigMaps—such as being mountable as volumes or used to set environment variables—they possess a distinct security feature. Data stored within a Kubernetes Secret is encoded using base64^[400-devops__06-Kubernetes__k8s-ithelp__Day16__README.md].

This encoding allows the system to handle binary data like certificates or keys, though it is important to note that base64 is an encoding scheme, not an encryption method; therefore, Secrets are typically configured to be encrypted at rest and secured via Role-Based Access Control (RBAC) policies within the cluster.
