This image provides tags Postgres with PostGIS extensions installed. This image is based on the official postgres image and provides the debian variant for PostGIS 3.5.x.
This image ensures that the default database created by the parent postgres image will have the following extensions installed:
| installed extensions | initialized |
|---|---|
postgis |
yes |
postgis_topology |
yes |
postgis_tiger_geocoder |
yes |
postgis_raster |
|
postgis_sfcgal |
|
address_standardizer |
|
address_standardizer_data_us |
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).
Check the documentation on the postgres image and Docker networking for more details and alternatives on connecting different containers.
See the PostGIS documentation for more details on your options for creating and using a spatially-enabled database.
Since the docker-postgis repository is an extension of the official Docker PostgreSQL repository, all environment variables supported there are also supported here:
POSTGRES_PASSWORDPOSTGRES_USERPOSTGRES_DBPOSTGRES_INITDB_ARGSPOSTGRES_INITDB_WALDIRPOSTGRES_HOST_AUTH_METHODPGDATA

Warning: the Docker specific variables will only have an effect if you start the container with a data directory that is empty; any pre-existing database will be left untouched on container startup.
It's crucial to be aware that in a cloud environment, with default settings, these images are vulnerable, and there's a high risk of cryptominer infection if the ports are left open. ( Read More )
