This dockerization is based on project of Alessandro Pasotti (elpaso,


Create a file .env (or copy .env.example and rename it in .env) and place it in the main directory, the file will contain the database credentials (change <your password>) and other settings:

# External hostname, for docker internal network aliases

# DB setup

# Caching

# URL of the QGIS Server

# Set G3W-SUITE debug state
G3WSUITE_DEBUG = 1 (0 default)



The main suite image can be built with:

docker build -f Dockerfile.g3wsuite.dockerfile -t g3wsuite/g3w-suite-dev:latest --no-cache .

The container image is build from --branch v.3.0.x

The Docker hub name for this image is g3wsuite/g3w-suite-dev:latest


Postgis image can be built with:

docker build -f Dockerfile.postgis -t g3wsuite/postgis:11.0-2.5 .

The Docker hub name for this image is g3wsuite/postgis:11.0-2.5

HTTPS additional setup

  • check the domain name in the .env file and in config/nginx/django_ssl.conf

  • run mkdir -p /shared-volume/ssl/certs/

  • run sudo openssl dhparam -out /shared-volume/ssl/certs/dhparam-2048.pem 2048

  • run: docker pull certbot/certbot

  • launch ./

  • make sure the certs are renewed by adding a cron job with crontab -e and add the following line: 0 3 * * * /home/g3w-suite/

  • if you disabled HTTPS, you can move config/nginx/django_ssl.conf back to its original location now, and restart the Docker compose to finally enable HTTPS


docker-compose up -d


  • web application: 8080


Data, projects, uploads and the database are stored in a shared mounted volume shared-volume, the volume should be on a persistent storage device and a backup policy must be enforced.

First time setup

  • log into the application web administation panel using default credentials (admin/admin)

  • change the password for the admin user and for any other example user that may be present


Tile cache can be configured and cleared per-layer through the webgis admin panel and lasts forever until it is disabled or cleared.

Tip: enable cache on linestring and polygon layers.

Style customization

Templates can now be overridden by placing the overrides in the config/g3w-suite/overrides/templates, a Docker service restart is required to make the changes effective.

The logo is also overridden (through config/g3w-suite/ which is mounted as a volume), changes to the settings file require the Docker service to be restarted.

A custom CSS is added to the pages, the file is located in config/g3w-suite/overrides/static/style.css and can be modified directly, changes are effective immediately.

Performances optimization

General rules (in no particular order: they are all mandatory):

  1. set scale-dependent visibility for the entire layer or for some filtered features (example: show only major roads until at scale 1:1E+6)

  2. when using rule-based/categorized classification or scale-dependent visibility create indexes on the column(s) involved in the rule expression (example: “create index idx_elec_penwell_ious on elec_penwell_ious (owner);” )

  3. start the project with only a few layers turned on by default

  4. do not turn on by default base-layers XYZ such as (Google base maps)

  5. do not use rule-based/categorized rendering on layers with too many categories (example: elec_penwell_public_power), they are unreadable anyway

  6. enable redering simplification for not-point layers, set it to Distance 1.2 and check Enable provider simplification if available

PostgreSQL administration

Postgres is running into a Docker container, in order to access the container, you can follow the instruction below:

Check the container name

$ docker ps | grep postgis
84ef6a8d23e6        g3wsuite/postgis:11.0-2.5       "/bin/sh -c /docker-…"   2 days ago          Up 2 days >5432/tcp           g3wsuitedocker_postgis_1

In the above example the container name is g3wsuitedocker_postgis_1

Log into the container

$ docker exec -it g3wsuitedocker_postgis_1 bash

Become postgres user

root@84ef6a8d23e6:/# su - postgres

Connect to postgis

postgres@84ef6a8d23e6:~$ psql
psql (11.2 (Debian 11.2-1.pgdg90+1))
Type "help" for help.
