Storing Secrets with Telegraf

Telegraf is an open source plugin-driven agent for collecting, processing, aggregating, and writing time series data, allowing users to store sensitive data such as secrets securely using various secret store plugins including Docker, HTTP, JOSE, and OS-specific stores. The new Secret Store feature enables users to reference these secrets in their Telegraf configuration files without exposing them directly, alleviating the need for hard-coded credentials. To get started with Secret Stores, users must first verify plugin support, choose a secret store, add it to their Telegraf config, set up necessary configuration options, save secrets to that store, and update their config to use secrets, often using syntax such as @{secretstore_id:secret_key} to reference the stored secrets.
