This is the base Docker image we use for Postgres/PostGIS. It also includes ogr_fdw and tds_fdw for copying/hosting data to and from a variety of sources, as well as Paul Ramsey's addressing dictionary. You can customize the extensions you want via the Dockerfile and initdb-postgis.sh.
There are three things you should edit before you start the docker container for the first time.
docker-compose.yml includes the PG admin password, a read-only login and password for the GIS database, and performance tuning options from PGTune. You should change these to fit your needs.
The top of the Dockerfile has the Postgres Major:Minor version, the PostGIS major version, and the time zone. Set those as needed. You can find the Postgres versions available on the official Docker postgres page.
FROM postgres:16
ENV POSTGIS_MAJOR 3
ENV TZ America/New_York
initdb-postgis.sh contains all the commands that initialize the Postgres server and database settings. You should modify it as needed - create different databases and users, install different extensions, etc.
docker-compose is used to manage the service.
Start the service (note the first start will install the docker images and software and will take a while):
docker-compose up -dStop the service:
docker-compose downThe backup shell script pgbackup.sh is installed to the Docker image, but running the backup script and starting the server itself is handled on the host. On a Linux host, I use cron for this. Note the paths and the name of the docker image and adjust accordingly.
@reboot sleep 10 && /usr/bin/docker-compose -f /path/to/project/folder/docker-compose.yml up -d
@daily docker exec postgres15.1-postgis3.3 /opt/pgbackup.shThe backup script removes backups over 7 days old before it runs so you don't fill your drive. Adjust as needed.
