Database Lab Client CLI reference (dblab)

Description

The Database Lab Command Line Interface, dblab, is a tool that allows to work with Database Lab instances in console. This tool is also used to enable working with thin clones in CI/CD pipelines, to run automated tests on full-size databases copies.

Getting started

Before you run any commands, install Database Lab CLI and initialize configuration. For more information, see Install and initialize Database Lab CLI.

⚠ If you register a Database Lab instance on the Postgres.ai Platform through the Platform server tunnel, it means that to use Database Lab API and CLI, your users need to be able to reach your infrastructure somehow. Consider use of VPN or custom SSH port forwarding.
