Dockerfile for CitusDB, sharded scalable postgresql database.
The image is based off of the official postgres image and supports the same options. When used with the provided docker-compose configuration, a workerlist-gen container is responsible for updating the worker list file and signalling the master node to reload changes.
The image defined in this repo can be tested using docker compose.
To launch a minimal Citus cluster (one master and one worker): docker-compose -p citus up. The -p flag specifies a custom project name (defaults to current working directory's name, which is often unsightly).
To bring the worker count up to three: docker-compose -p citus scale worker=3
For an example for setting up a distributed table and on how to run queries on it, see Querying Raw Data — CitusDB Documentation.
These commands should be run from inside your Docker instance:
docker exec -it citus_master bash
apt-get update; apt-get install -y wget
wget http://examples.citusdata.com/github_archive/github_events-2015-01-01-{0..5}.csv.gz
gzip -d github_events-2015-01-01-*.gz
psql
