Step 1: verify tools and compatibility

Choose Magento, PHP, Composer, database, and search versions from the current system-requirements matrix. This guide uses placeholders because supported combinations change.

Check DDEV and Docker

Confirms the local container tooling is available before project configuration.

ddev version
docker version

When to use itResolve installation or daemon errors before creating the project.

Create and enter the project directory

Creates an isolated directory for Magento and DDEV configuration.

mkdir <project-directory>
cd <project-directory>

When to use itUse a short lowercase directory name that does not contain credentials or client data.

Step 2: configure DDEV and the search service

Magento serves public files from pub/. Set a supported PHP version and review the generated .ddev/config.yaml before starting.

Configure the Magento project

Creates DDEV configuration for Magento with its correct document root and media upload directory while the application is being installed.

ddev config --project-type=magento2 --docroot=pub --upload-dirs=media --disable-settings-management --php-version=<supported-php-version>

When to use itReplace the PHP placeholder using the chosen Magento release’s requirements.

Add OpenSearch

Adds the maintained OpenSearch service definition to the local project.

ddev add-on get ddev/ddev-opensearch

When to use itUse when the selected Magento version requires or supports OpenSearch for catalogue search.

Start and inspect services

Starts the project and shows local URLs and service details.

ddev start
ddev describe

When to use itConfirm that web, database, and search services are healthy before installing Magento.

Step 3: handle Adobe repository credentials

Adobe Commerce Marketplace access keys are secrets. Never publish them, commit auth.json, or leave real keys in a shared command file.

Configure placeholder repository authentication

Stores Adobe repository authentication in the container’s Composer configuration.

ddev composer config --global --auth http-basic.repo.magento.com <public-key> <private-key>

When to use itReplace placeholders only in a private terminal and follow your team’s secret-management policy.

CautionThis syntax can enter values into shell history. Prefer a secure interactive or secret-injection workflow where available.

Check Composer configuration

Runs Composer diagnostics without printing the private key in this guide.

ddev composer diagnose

When to use itUse to identify network, certificate, or configuration problems before create-project.

Step 4: download the Magento project

Pick an explicit release after checking current security and compatibility guidance. Do not copy a stale version from an old command note.

Create the Magento codebase

Downloads the requested Magento Open Source release and its locked dependencies into the current directory.

ddev composer create-project --repository https://repo.magento.com/ magento/project-community-edition . "<magento-version>"

When to use itReplace the version placeholder with an approved release and run in an otherwise empty project directory.

Validate dependencies

Checks Composer metadata and confirms that required PHP extensions and versions are present.

ddev composer validate
ddev composer check-platform-reqs

When to use itResolve failures instead of using --ignore-platform-reqs.

Step 5: install Magento with local-only values

DDEV’s conventional database host, name, user, and password are db, db, db, and db. All store and administrator values below remain placeholders.

Run the Magento installer

Creates the Magento database, store configuration, search connection, and first local administrator.

ddev magento setup:install \
  --base-url='https://<project-name>.ddev.site/' \
  --db-host=db --db-name=db --db-user=db --db-password=db \
  --admin-firstname=<first-name> --admin-lastname=<last-name> \
  [email protected] --admin-user=<admin-user> \
  --admin-password='<strong-local-password>' \
  --language=en_US --currency=USD --timezone=<timezone> \
  --use-rewrites=1 \
  --search-engine=opensearch --opensearch-host=opensearch --opensearch-port=9200

When to use itReplace every angle-bracket placeholder. Keep these values local and use the actual DDEV project hostname.

CautionDo not reuse production credentials or publish the completed command.

Step 6: verify the installation

Finish with explicit status checks so a partially working environment is caught immediately.

Enable developer mode locally

Enables developer-oriented error reporting and asset behavior for a local environment.

ddev magento deploy:mode:set developer

When to use itUse for local development, never as a production deployment shortcut.

Restore DDEV settings management

Allows DDEV to manage Magento’s local environment settings after installation.

ddev config --disable-settings-management=false

When to use itRun after setup:install succeeds, as recommended by DDEV’s Magento quickstart.

Clean, index, and launch

Cleans generated cache state, builds indexes, and opens the local storefront.

ddev magento cache:clean
ddev magento indexer:reindex
ddev launch

When to use itVerify both the storefront and the generated Admin URL after these commands finish.
