Installing TYPO3 with DDEV

This is a step-by-step guide detailing how to install TYPO3 using DDEV, Docker and Composer.

DDEV is used for local development only.

Pre-Installation Checklist

  1. Install Docker - Visit to download and install the recommended version of Docker for your operating system.

  2. Install DDEV - Follow the DDEV installation guide to install DDEV.

DDEV and Docker need to be installed on your local machine before TYPO3 can be installed. If you need help installing DDEV, support can be found on the DDEV Discord server.

Create the Installation Directory

Create an empty directory to install TYPO3 in and then change into that directory:

mkdir t3example
cd t3example

Create a new DDEV Project

The ddev config command will prompt for information about your project. TYPO3 is in the list of preconfigured projects.

ddev config --php-version 8.1

# Give the following answers when prompted:

Project name (t3example):

Docroot Location (current directory): public

Create docroot at /home/myuser/projects/t3/t3example/public? [Y/n] (yes): Y

Project Type [php, typo3, ...] (php): typo3

Should always be "typo3"


Is the folder in which all files that have to be reached by the browser. This folder is commonly called public.


As the directory does not exist yet, this allows DDEV to create it for you.

Alternatively you can skip the prompt by supplying all of the required parameters in a single command:

ddev config  --project-type=typo3 --docroot=public --create-docroot --php-version 8.1

Start the project

ddev start

The webserver is now running but TYPO3 is not installed.

Install TYPO3

ddev composer create "typo3/cms-base-distribution:^12"

As we just created the project and have no, answer yes when prompted if it is ok to overwrite files in this directory.

You now have a Composer-based TYPO3 installation.

Run the Installation Setup Tool

Setup TYPO3 in the console

New in version 12.1: Starting with TYPO3 12.1 a new CLI command setup is introduced as an alternative to the existing GUI-based web installer.

Interactive / guided setup (questions/answers):

ddev exec ./vendor/bin/typo3 setup

Setup TYPO3 with the 1,2,3 Install Tool in the browser

Create a file called FIRST_INSTALL in your webroot

ddev exec touch public/FIRST_INSTALL

Open the installer

ddev launch typo3/install.php

Go to the TYPO3 backend:

ddev launch typo3

And login with the credentials you just provided.

Managing the Database

Upon calling ddev config DDEV automatically created a database for you. DDEV also created a file called config/system/additional.php in which it stored the database credentials for you.

During the installation setup process TYPO3 created all the tables it needed. If you want to have a look at the database, you can run the following command:

ddev launch -p

Sending E-Mail

DDEV creates config/system/additional.php to fake sending mails. You can see what mails have been sent here:

ddev launch -m

Stopping a DDEV Instance

If you want to stop all projects from running you can call:

ddev poweroff

The projects will stay configured and databases will be persisted.

Deleting a DDEV Instance

If you want to delete the project you just created you can remove it by calling the following command in your new projects root folder:

ddev delete --omit-snapshot

This will remove all containers from the project and delete the database.

Afterwards you can safely delete the project's root folder.
