PostgreSQL

Using PostgreSQL container with PostGIS support provided by mdillon/postgis.

Installation

  1. Copy docker-compose.postgres.yaml to your project
  2. Copy the full commands/postgres directory to your project's .ddev/commands directory. For example cp -r commands/postgres /.ddev/commands
  3. (optional) Update your config.yaml file to support auto-import/auto-export (see below)

Connection

Connect to postgres host/db server from within the web container with:

Host: postgres
User: db
Password: db
Database: db

For external access, use the port used in your docker-compose.postgres.yaml and 127.0.0.1 as host.

When using multiple project with PostgreSQL support, remember to update your docker-compose.postgres.yaml to use different ports:

    ports:
      - <EXTERNAL_PORT>:5432

Import / Export

Two new ddev commands are provided:

  • ddev pgsql_export : Use pg_dump to export db to .ddev/import-db/postgresql.db.sql
  • ddev pgsql_import : Use pgsql to import .ddev/import-db/postgresql.db.sql into db - Note that this must be executed with an empty database.

Example config.yaml hooks configuration to automatically import/export the db table:

# Add psql to your webserver
webimage_extra_packages: [postgresql-client]

# Automatically import and export PostreSQL database on ddev start and stop
hooks:
  pre-stop:
    - exec-host: ddev pgsql_export
  post-start:
    - exec-host: ddev pgsql_import

PostGIS

The postgres image support postgis, but you will need to create the extension before using it:

CREATE EXTENSION IF NOT EXISTS `postgis`;

Typo3 Notice

Typo3 CMS supports PostgreSQL natively, but the Typo3 Installer has issues with the default db database because the postgis extension is enabled per default.

You will need to disable the extension before the installation:

DROP EXTENSION postgis CASCADE;

It’s safe to re-enable postgis after the installation is complete.

TODO

Future enhancements (PR's welcome here) include:

  • Provide interactive custom commands to interact with the postgres utility in the container interactively.
  • Consider changing suggested import/export hooks into "exec" hooks with "service: postgres" instead of running ddev pg* on the host.
