docker-postgresql-postgis

The postgresql-postgis image provides a Docker container running Postgres 9.5 with PostGIS 2.2 installed.

The PostGIS extension can be installed into your database in the standard way via psql:

CREATE EXTENSION postgis;
CREATE EXTENSION postgis_topology;

Usage

In order to run a basic container capable of serving a PostGIS-enabled database, start a container as follows:

docker run --name some-postgis -e MAX_CONNECTIONS=400 -d jmmoreno/docker-postgresql-postgis

For more detailed instructions about how to start and control your Postgres container, see the documentation for the postgres image here.

Once you have started a database container, you can then connect to the database as follows:

docker run -it --link some-postgis:postgres --rm postgres \
    sh -c 'exec psql -h "$POSTGRES_PORT_5432_TCP_ADDR" -p "$POSTGRES_PORT_5432_TCP_PORT" -U postgres'

Using the resulting psql shell, you can create a PostGIS-enabled database by using the CREATE EXTENSION mechanism:

CREATE EXTENSION postgis;
CREATE EXTENSION postgis_topology;

See the PostGIS documentation for more details on your options for creating and using a spatially-enabled database.

Configuration (environment variables)

For the first run, one database could be created if next environment variables are supplied:

• POSTGRES_USER - creates an user with full privileges.
• POSTGRES_PASSWORD - password for POSTGRES_USER.
• POSTGRES_DB - default database for POSTGRES_USER.

Data persistence

If you want to make your data persistent, you need to mount a volume:

docker run ....... -v /opt/db/postgresql/data:/var/lib/postgresql/data .....

in order to make sure that everything is restored after a restart of the container (databases, configuration, ...).
