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.

In order to be able to build some assets (e.g. css, js files) you need to have yarn installed as described here.

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

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

Install dependencies via composer

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

ddev composer install

Check for database credentials

Let DDEV dump information:

ddev describe

You will need username, password, Database name, host and port of the MySQL credentials to setup your TYPO3 installation, e.g.:

MySQL Credentials
Username:            db
Password:            db
Database name:       db
Host:                db
Port:                3306



Creating FIRST_INSTALL is probably not necessary. Check to see if the database exists. ddev describe should give you enough information for that.

Now, create a file FIRST_INSTALL:


Setup your TYPO3 installation

Now load the URL as shown by ddev start in your browser with the path /typo3 appended to it. Typically this will be

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


ddev remove

ddev remove does not remove the database. For a list of commands see:

ddev help


If you don’t run “ddev stop” or “ddev remove” before shutting down or restarting docker the database might get corrupt and “ddev start” won’t work anymore with the error:

Failed to start <projectname>: db service health check timed out

keep in mind, this will remove your data entirely

try running:

ddev remove --remove-data


ddev start



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.
