Auto-deletion of clones after some period of inactivity (by default, 2 hours).
Protection from deletion: a clone can be marked as "protected", which means that it cannot be deleted, neither manually nor automatically.
Postgres versions 9.6, 10, 11, 12 are supported.
Postgres clones are running in Docker containers. Custom Docker images are supported, to allow additional extensions, libraries, custom Postgres builds.
Custom postgresql.conf addition and pg_hba.conf replacement to control settings of Postgres clones.
For security, all Postgres users are disabled, and a new one is created (configure at clone request time).
Known issues and future work
Currently, to install Database Lab, a lot of software needs to be installed: Docker, Go, ZFS, Postgres, more. See Tutorial. Tested on Ubuntu 18.04. In the upcoming Database Lab versions, we will move everything to containers, which means that only Docker will be a requirement, and any modern Linux will be supported.
If a Database Lab instance is restarted, all the clones get deleted. We plan to implement persistent clones in the future versions, to keep all existing clones during restarts.
