DDEV simplifies integrating the power and consistency of containerization into your workflows. Set up environments in minutes; switch contexts and projects quickly and easily; speed your time to deployment. DDEV handles the complexity. You get on with the valuable part of your job.

Before proceeding, make sure your DDEV installation is up to date.

In a new project folder using your favorite shell, run these lines:

                                    ddev config --project-type=typo3 --docroot=public --php-version 8.1 --webserver-type 'apache-fpm'
                                    ddev composer create --no-install "typo3/cms-base-distribution:^12.4"
                                    ddev composer install
                                                                            ddev restart
                                                                                                                ddev typo3 setup --server-type=apache --driver=mysqli --host=db --port=3306 --dbname=db --username=db --password=db
                                        ddev restart
                                                                        ddev launch /typo3/

If you are experienced with Composer you can create your own composer.json and select the needed packages of TYPO3 via the Composer Helper. Instead of the ddev composer create command above, run the command created with the Composer Helper prepended with ddev. E.g.:

                                    ddev config --project-type=typo3 --docroot=public --php-version 8.1 --webserver-type 'apache-fpm'
                                    ddev composer require "typo3/cms-core:^12.4" "typo3/minimal:^12.4" ...
                                                                            ddev typo3 setup --server-type=apache --driver=mysqli --host=db --port=3306 --dbname=db --username=db --password=db
                                        ddev restart
                                                                        ddev launch /typo3/
                                
composer create-project "typo3/cms-base-distribution:^12.4" my-new-project

If you are experienced with Composer you can create your own composer.json and select the needed packages of TYPO3 via the Composer Helper.

Package Signatures

TYPO3 Release Packages (the downloadable tarballs and zip files) as well as Git tags are signed using PGP signatures during the automated release process. Besides that, MD5 and SHA2-256 hashes are being generated for these files. Find more details on verifying signatures and hashes in the infrastructure guide.
