It's a columnar store for analytics with Postgres, developed by Citus Data, bringing some astonishing performance for some data schema.
As the Docker entrypoint is the same as in the official PostgreSQL docker image, for custom environment, see details on the Dockerhub page.
For a simple container exposing its 5432 port without any mounted volume, with postgres as password for postgres user, you can run
$ docker run -d -p 5432:5432 -e POSTGRES_PASSWORD=postgres mnementh64/docker-postgresql-cstore
To mount data in host storage, launch
$ docker run -d -p 5432:5432 -e POSTGRES_PASSWORD=postgres -v host_path_to_data:/var/lib/postgresql/data mnementh64/docker-postgresql-cstore
To use a custom PostgreSQL configuration :
# copy template from the container
$ docker run -i --rm mnementh64/docker-postgresql-cstore cat /usr/share/postgresql/postgresql.conf.sample > my-postgres.conf
# customize it ...
# run postgres with custom config
$ docker run -d -p 5432:5432 -e POSTGRES_PASSWORD=postgres -v "$PWD/my-postgres.conf":/etc/postgresql/postgresql.conf mnementh64/docker-postgresql-cstore -c 'config_file=/etc/postgresql/postgresql.conf'
In a docker-compose :
version: "2"
services:
postgres:
image: mnementh64/docker-postgresql-cstore:10.3
ports:
- 5432:5432
volumes:
- /tmp:/tmp
# to use a custom config
#- ./my-postgres.conf:/etc/postgresql/postgresql.conf
# to persist data to host
#- /path_on_host/data:/var/lib/postgresql/data
# to use a custom config
#command: postgres -c config_file=/etc/postgresql/postgresql.conf
environment:
# user : postgres
POSTGRES_PASSWORD: "your_password"
