Setting up TYPO3 with DDEV

DDEV provides several pre-configured environments based on Docker.

Here is a description of how you can use DDEV to setup a working TYPO3 installation using the cloned master of the TYPO3 git repository.

You don’t need to have a Webserver or Database running on your system. Everything will be supplied by DDEV. In fact, if you do have a Webserver or Database running on your machine, make sure there are no conflicts. You can change the default ports DDEV uses (e.g. port 80 / 443 for Webserver) in .ddev/config.yaml before you start it.

You can watch a video tutorial about setting up TYPO3 with DDEV, or go through steps outlined below.

Setting up the prerequisites

You will need to install Docker and other ddev system requirements.

Then install DDEV as described in the Installation instructions.


Composer and yarn can run inside of DDEV, so there is no need to set them up locally.

Clone TYPO3

Create a clone of the TYPO3 git repository as described in git clone:

mkdir t3master
cd t3master
git clone git:// .

Configure DDEV

ddev config

DDEV should suggest the correct defaults and you just need to press ENTER:

> Project name (t3master):

> Docroot Location (current directory):

> Found a typo3 codebase at /var/www/t3master.
> Project Type [backdrop, drupal6, drupal7, drupal8, drupal9, laravel, magento, magento2, php, typo3, wordpress] (typo3):

In order to change the PHP version, edit the configuration file .ddev/config.yaml:

php_version: "7.3"

See supported version here:

Start DDEV

ddev start

DDEV should now show a URL under which the site can be reached:

> TYPO3 does not seem to have been set up yet, missing LocalConfiguration.php (/var/www/t3master/typo3conf/LocalConfiguration.php)
> Generating AdditionalConfiguration.php file for database connection.
> Successfully started t3master
> Project can be reached at

Ignore the warning about missing LocalConfiguration.php for now, we will take care of that below.

Install dependencies via composer

This runs inside the container and thus uses your configured PHP version:

ddev composer install

It is not necessary for the initial build, but once you change some assets (e.g. Typescript, SCSS files), you should build with yarn. You might like to try this now:

ddev exec "cd Build && yarn install"
ddev exec "cd Build && yarn build"

The first command is required once, the second (build) command is required after every change of a resource file.

DDEV describe

Let DDEV dump information:

ddev describe

You may need some of this later.


Create a file FIRST_INSTALL:


Setup your TYPO3 installation

Now load the URL as shown by ddev start or ddev describe in your browser, e.g.

You will now be guided through the basic installation steps by TYPO3.


If you use the HTTPS url you may get a “Privacy error” or something similar from your browser. You will need to get your browser to ignore this warning (e.g. Advanced:Proceed to t3master.ddev.local (unsafe), depends on browser).

The warning is due to the fact that self-signed certificates are being used.

If you are getting a trustedHostsPattern error on initial access, try accessing the HTTP domain first.

Additional setup

Be sure to add the .ddev directory to your local gitignore (e.g. .git/info/exclude).

Shutdown DDEV

When you are done you can do:

ddev stop

For a list of commands see:

ddev help

Remember, you can use the Slack channels to ask for help! Follow the general convention for the channels: not too chatty, get straight to the point and ask, be nice. Register for the TYPO3 slack workspace if you have not done so already.
