The mdillon/postgis image provides a Docker container running Postgres 9 or 10 with PostGIS 2.4 installed. This image is based on the official postgres image and provides variants for each version of Postgres 9 supported by the base image (9.3-9.6) and Postgres 10.

This image ensures that the default database created by the parent postgres image will have the following extensions installed:

• postgis
• postgis_topology
• fuzzystrmatch
• postgis_tiger_geocoder

Unless -e POSTGRES_DB is passed to the container at startup time, this database will be named after the admin user (either postgres or the user specified with -e POSTGRES_USER). If you would prefer to use the older template database mechanism for enabling PostGIS, the image also provides a PostGIS-enabled template database called template_postgis.

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 POSTGRES_PASSWORD=mysecretpassword -d mdillon/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'

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

When You encouter errors due to PostGIS update OperationalError: could not access file "$libdir/postgis-X.X, run:

docker exec some-postgis update-postgis.sh

It will update to Your newest PostGIS. Update is idempotent, so it won't hurt when You run it more than once, You will get notification like:
