Dockerfile for CitusDB, sharded scalable postgresql database.
The image is based off of the official postgres image and supports the same options.
In addition, new environment variables have been added:
CITUS_MASTER denotes that this instance is the citus master node. All citus workers
should be linked to this container (and should contain citus in their name).
CITUS_STANDALONE marks a citus master as a worker as well.
The image defined in this repo can be tested using docker compose.
To launch a citus cluster with a master node and 2 workers:
docker-compose up
For an example for setting up a distributed table and on how to run queries on it, see CitusData docs: Examples with Sample Data.
These commands should be run from inside your docker instance:
> docker exec -it citusdocker_citusmaster_1 bash
