TYPO3 DDEV Setup Skill

CRITICAL: URL Scheme

NEVER guess URLs. Read name: from .ddev/config.yaml, then apply the subdomain pattern:

https://v{VERSION}.{sitename}.ddev.site/typo3/ · Landing: https://{sitename}.ddev.site/ · Docs: https://docs.{sitename}.ddev.site/

Each version gets a vhost (/var/www/html/v{VERSION}) via additional_hostnames. Never infer URLs from directory listings.

Credentials: admin / Joh316!!

Container Priority

1. .ddev/ exists → ddev exec
2. docker-compose.yml → docker compose exec
3. System tools only if no container. Use project's configured PHP.

No DDEV available (CI, container, agent harness — DDEV drives Docker): read .ddev/config.yaml and .ddev/commands/, then scripts/provision-without-ddev.sh --extension . --serve. The distribution ships no .htaccess, so /typo3/ answers 200 while sub-routes 404 — references/without-ddev.md.

In-container edits: docker cp in, then ddev exec — not heredocs/php -r. See references/container-file-editing.md.

Quick Start

ddev start && ddev install-all    # All versions (11/12/13/14)
ddev install-v14                  # v14.3 LTS (default / gold standard)
ddev install-v13                  # v13.4 LTS

Database Selection

MariaDB 10.11 (default) · SQLite · PostgreSQL 16 · MySQL 8.0. See references/advanced-options.md, references/0002-mariadb-default-with-database-alternatives.md.

PHP Management

php_version: "8.3" in config.yaml. Upgrade via .ddev/web-build/Dockerfile. Settings: .ddev/php/custom.ini. See references/0003-php-version-management.md.

TYPO3 Version Differences

	v12	v13	v14.3 LTS
Setup	install:setup --use-existing-database	setup	setup
Activation	Auto	extension:setup	extension:setup
composer.json	optional	optional	required (#108310)
Theme	bootstrap-package	bootstrap-package	Camino (#108539)
Fluid	2.x	4.x	5.x strict (#108148)
CKEditor	41–42	41–42	47

See references/typo3-12-cli-changes.md.

Post-Setup Verification

ddev status, ddev describe, ddev exec -d /var/www/html/v13 vendor/bin/typo3 extension:list --active. Check a consequence, not a status: /typo3/login must answer 200. See references/post-setup-verification.md.

Optional Services & Commands

• Valkey 8 (default) or Redis 7: references/0001-valkey-default-with-redis-alternative.md
• Ofelia: scheduler automation · ddev generate-makefile / generate-index / docs / xdebug on

Extension Naming

Hyphens for composer (nr-llm), underscores for TYPO3 key (nr_llm). Source: composer.json name.

Troubleshooting

Issue	Solution
Port conflict	router_http_port: "8080" / router_https_port: "8443"
Database exists	ddev mysql -e "DROP DATABASE v13; CREATE DATABASE v13;"
Extension not found	ddev exec -d /var/www/html/v13 vendor/bin/typo3 cache:flush
Windows health check	/phpstatus endpoint with php-fpm.sock
PHP settings ignored	.ddev/php/custom.ini
Full cleanup	ddev delete --omit-snapshot --yes, remove volumes
