Configuring `.drupalaibp/`

A config is a *.json file inside a .drupalaibp/ directory in the place you launch the installer from. When one is present, the installer reads it and pre-configures the whole build — project type, coding agents, agent skills, provisioning (Composer packages, modules, recipes, DDEV add-ons), custom questions, and hook scripts fired at named build events.

# in a directory containing .drupalaibp/config.json
bash <(curl -fsSL https://project.pages.drupalcode.org/one_line_installer/drupalaibp)

Upgrading from 1.x? The single root .drupalaibp.json is no longer read. Move it into the directory: mkdir .drupalaibp && git mv .drupalaibp.json .drupalaibp/config.json.

The structural choices (profile, agents, skills, deny rules, provisioning) come from the config and aren't prompted. The config's questions are still asked interactively, each with its default pre-filled, so you can review or adjust them. Add --yolo to take every default silently and run fully unattended.

There are two complete, runnable examples in docs/examples/ — a Drupal site with provisioning, and a non-Drupal Node/Storybook project.

Where a config lives, and picking one

Every *.json directly under .drupalaibp/ is a named config — the file's basename (without .json) is its name. The simplest project has a single .drupalaibp/config.json.

One config in .drupalaibp/ is used automatically.
Several configs — pass --config <name> (the basename, no .json) to pick one, or choose interactively from the list. In an unattended run (--yolo, or a source loaded with no terminal) a multi-config directory with no --config is a hard error that names the available configs.

The same .drupalaibp/ directory can be loaded from several places — the launch directory (auto-detected), a positional source drupalaibp <source>, or the --config-path/--config-url/--global-config flags. See the setup-site reference for the full source list and flag equivalences.

Git sources and refs (`--config-url`)

A git URL source (drupalaibp <url> or --config-url <url>) is cloned and its .drupalaibp/ read. Pin a branch, tag, or ref two ways:

an @<ref> suffix on the URL — drupalaibp https://git.example.org/acme/site@1.2.x;
the --ref <ref> flag — --config-url https://git.example.org/acme/site --ref 1.2.x.

A ref may be a branch name, a tag, a full refs/… ref, or !<iid> for a GitLab merge request (!64 → refs/merge-requests/64/head).

Paths inside a config resolve relative to the config file

Because the config file sits inside .drupalaibp/, every config-relative path — hooks[].script, copy_paths, db_import_path — resolves against that .drupalaibp/ directory (CONFIG_BASEDIR). Reference a script or asset that lives next to the config as "./seed.sh" (→ .drupalaibp/seed.sh), and use a leading "../" to reach the repo root. (This differs from the pre-2.x root .drupalaibp.json, where such paths were relative to the repo root.)

Three things to get right

!!! warning "1. Drupal projects need a Drupal ddev_project_type" For a Drupal build (is_drupal: true, the default), ddev_project_type must be a Drupal type — "drupal11" (default), "drupal10", "drupal12", and so on. It is passed straight to ddev config --project-type. Using "php" or another generic type for a Drupal site will not configure Drupal correctly.

!!! warning "2. Non-Drupal builds ignore the Drupal-only keys" If you set is_drupal: false, the keys profile, site_template, install_modules and recipes do nothing — there's no composer create-project, drush, or config export. A non-Drupal build still sets up DDEV, coding agents, skills, ddev_addons and hooks; drive the actual project setup with hooks (e.g. npm/composer commands run in the web container). Set ddev_project_type to a non-Drupal DDEV type such as "php".

!!! tip "3. Keep hook scripts next to the config" Store hook scripts in the same .drupalaibp/ directory as the config and reference them as "./<name>.sh" (paths resolve relative to the config file, which lives inside .drupalaibp/). Paths must be whitespace-free and are copied into the new project root before they run. Use a leading "../" only if a script deliberately lives at the repo root.

Key reference

Key	Applies to	Notes
`ddev_project_type`	all	`ddev config --project-type`. Drupal builds must use `drupal11`/`drupal10`/`drupal12`/… (see point 1).
`is_drupal`	all	default `true`. `false` skips every Drupal step.
`docroot`	all	`ddev config --docroot`. Default `"web"` (Drupal) / `"."` (non-Drupal).
`launch_path`	all	`ddev launch` argument override, e.g. `":6006"` for a dev-server daemon on its own port. Default: launches the project root.
`profile`	Drupal	`cms` (default), `standard`, `minimal`, `template`.
`site_template`	Drupal	site-template project short name (with `profile: template`).
`install_modules`	Drupal	enabled with `drush`.
`recipes`	Drupal	apply-only (`drush recipe`); never fetched. A `drupal/<name>` entry is applied from `../recipes/<name>` — fetch it via `composer_projects`. Any other entry (e.g. `core/recipes/standard`) is passed to `drush` verbatim, so a core / already-present recipe applies with no fetch.
`agents`	all	coding agents installed into the container.
`agent_auto_mode`	all	default `false`. `true` prepends each agent's own unattended flag to its `ddev <agent>` wrapper (Claude `--permission-mode auto`, Codex `--dangerously-bypass-approvals-and-sandbox`, OpenCode `--auto`). Config-only — no CLI flag or prompt.
`extra_scripts`	all	ids of "Extra Drupal Installations" (`src/lib/extras/extra_<id>.sh`) to run — the config equivalent of `--extras`.
`skills`	all	single list; `"owner/repo"` (all) or `{repo, skills:[…]}` (`["*"]` = all).
`deny_commands`	all	commands the agent(s) may never run.
`composer_stability`	composer	`minimum-stability`; default `dev`.
`composer_with_all_dependencies`	composer	default `false`. `true` adds `--with-all-dependencies` (`-W`) to the `composer_projects` require, so Composer may update the whole dependency tree (needed when a package — e.g. a recipe you fetch here — requires newer shared deps).
`composer_allow_plugins`	composer	plugins to trust; is_drupal adds core-dev/ABP defaults.
`repositories`	composer	registered before `composer_projects`.
`composer_projects`	composer	fetch-only — verbatim `composer require` args, version constraints allowed (`drupal/ai:^1.1`); never applied/enabled. Fetch a contrib recipe here, then apply it via `recipes`.
`ddev_addons`	all	added after the site is built, then one `ddev restart`.
`agents_md`	all	paragraphs appended to the managed `AGENTS.md` block.
`copy_paths`	all	extra files/directories copied into the project root, same path convention as `hooks[].script` — for hook-consumed assets that aren't scripts themselves.
`db_import`	`--config-url`	default `false`. `true` selects existing-codebase mode (the clone IS the Drupal codebase) with the dump supplied at runtime via `--db-path`. Mutually exclusive with `db_import_path`.
`db_import_path`	`--config-url`	a dump committed in the repo, path relative to the config file — same existing-codebase mode as `db_import`, but resolved automatically, no `--db-path` needed.
`append_welcome_text`	all	paragraph(s) appended to the end of the `print_welcome` summary. Ignored if `replace_welcome_text` is set.
`replace_welcome_text`	all	paragraph(s) that replace the entire `print_welcome` summary (no admin login, no handy commands, no DDEV footer) — takes precedence over `append_welcome_text`.
`questions`	all	see below; answers → `.ddev/.env`.
`hooks`	all	see below.

Welcome-text placeholders and colors

Both append_welcome_text and replace_welcome_text support {TOKEN} substitution:

Built-in tokens:

Token	Value
`{PROJECT_NAME}`	the DDEV project name (lowercased directory name)
`{SITE_URL}`	`https://<project>.ddev.site`
`{DRUPAL_USERNAME}`	`admin`
`{DRUPAL_PASSWORD}`	`admin`
`{DRUPAL_LOGIN_URL}`	`{SITE_URL}/user`

Env-var tokens: any questions[].env answer is addressable by its own name, e.g. {OPENAI_API_KEY}, {SITE_FLAVOR}.

{
  "append_welcome_text": [
    "Environment: {SITE_ENV}  •  Flavor: {SITE_FLAVOR}",
    "Log in at {DRUPAL_LOGIN_URL} with {DRUPAL_USERNAME} / {DRUPAL_PASSWORD}."
  ]
}

!!! warning "Unknown tokens print literally" A {TOKEN} that isn't a built-in or a questions[].env name is left untouched in the output (not emptied) — this surfaces a typo instead of silently hiding it.

!!! warning "Secrets land on the terminal" A password-type question's answer, if referenced by a welcome-text placeholder, is echoed to the terminal in the final build summary. Don't reference a genuinely sensitive value this way unless you're fine with it appearing in that output.

Colors: {BOLD}, {DIM}, {GREEN}, {YELLOW}, {RED}, {RESET} expand to the installer's own color codes when connected to a real terminal, and to nothing when output isn't a TTY (piped/redirected), so logs stay clean. Every paragraph also gets an automatic trailing reset, so an unclosed color token can't bleed into the next paragraph or the rest of the terminal.

{
  "append_welcome_text": "{BOLD}{GREEN}Welcome to the ACME demo!{RESET} Docs: https://example.com/handbook"
}

Questions

Each question object uses env (the environment-variable name — a valid identifier), label, type, and optionally default, select_options, value, depends_on.

Types: text, password, single-select-options, multi-select-options.
select_options — the choice list for the two select types.
default — pre-fills an editable prompt (still shown).
value — pre-answers the question, so it is not shown. Use default (not value) if you want a question prompted with a suggestion.
Answers land in .ddev/.env (mode 600, gitignored). Never put a real secret in value — leave it for the user to type.

Conditional questions (`depends_on`)

A question can be shown only when an earlier question's answer matches a condition:

{
  "env": "REDIS_TTL",
  "label": "Redis cache TTL (seconds)",
  "type": "text",
  "default": "3600",
  "depends_on": { "env": "USE_REDIS", "equals": "yes" }
}

depends_on.env must name a question that appears earlier in the questions array. A forward reference, self-reference, or a name that doesn't match any earlier question is invalid: it's ignored with a warning and the question is asked unconditionally instead of being dropped.
Condition kinds (exactly one required): "equals": "<value>", "not_equals": "<value>", or "in": ["a", "b", ...] (the dependency's answer is one of the listed values — useful when a select has more than two meaningful options).
A question whose condition isn't met is not shown, and its ANSWERS value is set to an empty string — still written to .ddev/.env as KEY="", so hooks and welcome-text tokens can test for emptiness rather than the variable being entirely undefined.
value still short-circuits a question before depends_on is ever evaluated for it — a pre-answered question is never conditionally skipped, it's simply always answered from value.

!!! warning "Any depends_on disables .ddev/.env reuse for the whole block" Normally a question already answered in a previous run (its key already present in .ddev/.env) is reused silently instead of being re-prompted — this is what makes a re-run in management mode not re-ask everything. A conditional question's visibility has to reflect the current answer of its dependency, not a possibly-stale one from a previous run — so the presence of any depends_on anywhere in a config's questions disables that reuse for the entire array, on every run, including questions with no depends_on of their own and password questions. A config with no conditional questions is unaffected. If you add one conditional question to a config, every question in that config (including secrets) will be re-prompted on every future re-run of that config.

Hooks and events

Each event name maps to a list of { script, weight, where }:

weight — integer; lower runs first.
where — host, web (default; runs in the DDEV web container via ddev exec), or a named DDEV service.

!!! warning "Pre-start hooks must use where: host" web/service hooks need the container running. A hook on a pre-start event (before_ddev_start, ddev_addon_added, coding_agent_added, or anything before ddev_started) must set "where": "host".

!!! warning "Question answers are only in the container" Answers from questions are written to .ddev/.env, which DDEV injects into the web container — not the host. A "where": "web" hook sees them as environment variables ($OPENAI_API_KEY, …); a "where": "host" hook does not. If a hook needs a question's answer, run it in web.

Available events: before_<step> / <step>_done for every pipeline step, plus the semantic events before_ddev_start, ddev_started, coding_agent_added, ddev_addon_added, skill_added, and ask_questions. The most common are ddev_started (the site is up — run drush/composer/npm in web) and coding_agent_added (host-side — tweak AGENTS.md).

!!! note "Hook script and copy_paths staging timing (Drupal fresh-scaffold builds)" For is_drupal: true fresh-scaffold builds (without db_import or db_import_path), copy_paths and most hook scripts are staged after Drupal scaffolding completes (create_drupal_site_done), not before. This is because ddev composer create-project refuses a non-empty project directory.

**Exception: hook scripts on early events.** A hook script registered on an
event that fires **before** Drupal's scaffold
(`before_ddev_start`, `ddev_started`, `coding_agent_added`,
`ask_questions`, or `before_create_drupal_site` itself)
is staged early, but physically lives **only** at
`.ddev/drupalaibp-hooks/<configured-path>` in the final scaffolded
project — **not** at the `script` path written in the config.
This is a real, user-visible difference from every other hook script
(which does land at its configured path in the project root):
an early hook is classified as such and never additionally copied to where
a late hook would be. If you inspect the scaffolded project, an early
hook's script will only be found under `.ddev/`, not in the root.

**Existing-codebase mode and non-Drupal builds are unaffected:**
When `db_import` or `db_import_path` is set, or when `is_drupal: false`,
all hook scripts and `copy_paths` use the original timing — no
deferral, no `.ddev/`-only staging.

Importing Drupal config (`.drupalaibp/config/`)

Drupal-only. Drop a .drupalaibp/config/ directory (a config/ subdirectory inside .drupalaibp/, alongside the config JSON) containing exported Drupal config YAML, and after the site is installed and provisioned the installer runs a partial drush config:import from it:

my-launch-dir/
└── .drupalaibp/
    ├── config.json             # the installer config
    └── config/
        └── system.site.yml     # e.g. override the site name

It's a partial import — the provided config is applied on top of the installed site; config not present in the directory is left alone (nothing is deleted). This runs after provision_from_config, so config that references modules from install_modules imports cleanly. Ignored for is_drupal: false builds and when the directory has no *.yml. See docs/examples/drupal/ for a working system.site.yml.

Good to know

selenium / toolbelt / dtk are not flags — they're ordinary provisioning: Selenium as a ddev_addons entry (a built-in handler makes Chrome headed with noVNC on port 7900), Toolbelt/DTK as composer_projects + install_modules.
AI Best Practices + core-dev (drupal/ai_best_practices, drupal/core-dev, and a starter phpunit.xml) are built-in defaults for every is_drupal: true build — you don't list them. ai_best_practices is installed and its Composer plugin allow-listed automatically.
The experimental Tool API + Toolbelt (drupal/tool + drupal/tool_belt, so agents can run Drupal actions via drush tool:*) is suggested during an interactive build (or --tool-api). In a config, add it through composer_projects + install_modules (+ tbachert/spi in composer_allow_plugins).
Build order: DDEV starts vanilla, the Drupal site is created, then ddev_addons are added and applied with a single restart (some add-ons write files outside .ddev/ that would otherwise break composer create-project).
To replace the whole AGENTS.md block content, drop an overrides/agents_md.json next to the config.

Examples

See the runnable examples and their hook scripts under docs/examples/:

docs/examples/drupal/ — is_drupal: true, Drupal CMS on Drupal 11, with a private repo, version-constrained composer projects, modules, a recipe, the Selenium + Redis add-ons, password + select questions, and .drupalaibp/ hook scripts on ddev_started and coding_agent_added.
docs/examples/storybook/ — is_drupal: false, a Node/Storybook project built entirely through where: web npm hooks; every question type drives the npm setup.
