Practical examples of using Greenmask for test data management.
local environment example — developer environment with production-like data
Shows how a developer can spin up a local database pre-loaded with an anonymized dump pulled from corporate S3
storage. The full stack (MinIO + Postgres + your service) starts with a single docker compose up — no live
source database, no manual data-prep step.
custom json transformer — Json transformer example via Cmd:
Shows how to implement complex transformation logic in Python and wire it into Greenmask as an external
transformer using the Cmd built-in. Covers JSON field transformation as a worked example.
