How deeply does Machine Learning Platform Engineering cover Kubernetes Secret?

Defines a v1 YAML object, creates and inspects it with kubectl, and demonstrates field retrieval and workload references.

Kubernetes Secret

As explained in Machine Learning Platform Engineering

A Kubernetes Secret is an API object for storing and supplying sensitive data to workloads.

A Kubernetes Secret is an API object for storing sensitive values and supplying them to workloads. A typical Secret uses apiVersion v1, kind Secret, an object name, type Opaque, and data fields whose values are represented as base64 strings.

Credential Secret

The test-secret object stores database_username and database_password under type Opaque. A kubectl template command retrieves one field and pipes it to base64 -d for inspection.
