Configuration

This page describes all configuration options for the application server. All settings must be configured in the environment of the application server, usually by adding them to the .env file.

Required Settings

The following settings need to be set appropriately for your installation. They are included in the default env.template.

Secret Key

Random secret key (at least 50 characters), use for example base64 /dev/urandom | head -c50 to generate one. It is used internally by django for various signing/cryptographic operations and should be kept secret. See Django Docs

SECRET_KEY=#$tp%v6*(*ba01wcz(ip(i5vfz8z$f%qdio&q@anr1#$=%(m4c

Alternatively you can point to a file containing just the secret key value. If using containers make sure the file is persistent and available inside the container.

SECRET_KEY_FILE=/path/to/file.txt

// contents of file
#$tp%v6*(*ba01wcz(ip(i5vfz8z$f%qdio&q@anr1#$=%(m4c

Database

Multiple parameters are required to configure the database.

Var Options Description
DB_ENGINE django.db.backends.postgresql (default) django.db.backends.sqlite3 Type of database connection. Production should always use postgresql.
POSTGRES_HOST any Used to connect to database server. Use container name in docker setup.
POSTGRES_DB any Name of database.
POSTGRES_PORT 1-65535 Port of database, Postgresql default 5432
POSTGRES_USER any Username for database connection.
POSTGRES_PASSWORD any Password for database connection.

Password file

default None - options: file path

Path to file containing the database password. Overrides POSTGRES_PASSWORD. Only applied when using Docker (or other setups running boot.sh)

POSTGRES_PASSWORD_FILE=

Connection String

default None - options: according to database specifications

Instead of configuring the connection using multiple individual environment parameters, you can use a connection string. The connection string will override all other database settings.

DATABASE_URL = engine://username:password@host:port/dbname

Connection Options

default {} - options: according to database specifications

Additional connection options can be set as shown in the example below.

DB_OPTIONS={"sslmode":"require"}

Optional Settings

All optional settings are, as their name says, optional and can be ignored safely. If you want to know more about what you can do with them take a look through this page. I recommend using the categories to guide yourself.

Server configuration

Configuration options for serving related services.

Port

default 8080 - options: 1-65535

Port for gunicorn to bind to. Should not be changed if using docker stack with reverse proxy.

TANDOOR_PORT=8080

Allowed Hosts

default * - options: recipes.mydomain.com,cooking.mydomain.com,... (comma seperated domain/ip list)

Security setting to prevent HTTP Host Header Attacks, see Django docs. Many reverse proxies handle this and require the setting to be * (default).

ALLOWED_HOSTS=recipes.mydomain.com

URL Path

default None - options: /custom/url/base/path

If base URL is something other than just / (you are serving a subfolder in your proxy for instance http://recipe_app/recipes/) Be sure to not have a trailing slash: e.g. '/recipes' instead of '/recipes/'

SCRIPT_NAME=/recipes

Static URL

default /static/ - options: /any/url/path/, https://any.domain.name/and/url/path

If staticfiles are stored or served from a different location uncomment and change accordingly. This can either be a relative path from the applications base path or the url of an external host.

Info

  • MUST END IN /
  • This is not required if you are just using a subfolder
STATIC_URL=/static/

Media URL

default /static/ - options: /any/url/path/, https://any.domain.name/and/url/path

If mediafiles are stored at a different location uncomment and change accordingly. This can either be a relative path from the applications base path or the url of an external host

Info

  • MUST END IN /
  • This is not required if you are just using a subfolder
  • This is not required if using S3/object storage
MEDIA_URL=/media/

Gunicorn Workers

default 3 - options 1-X

Set the number of gunicorn workers to start when starting using boot.sh (all container installations). The default is likely appropriate for most installations. See Gunicorn docs for recommended settings.

GUNICORN_WORKERS=3

Gunicorn Threads

default 2 - options 1-X

Set the number of gunicorn threads to start when starting using boot.sh (all container installations). The default is likely appropriate for most installations. See Gunicorn docs for recommended settings.

GUNICORN_THREADS=2

Gunicorn Media

default 0 - options 0, 1

Serve media files directly using gunicorn. Basically everyone recommends not doing this. Please use any of the examples provided that include an additional nxginx container to handle media file serving. If you know what you are doing turn this on (1) to serve media files using djangos serve() method.

GUNICORN_MEDIA=0

CSRF Trusted Origins

default [] - options: [list,of,trusted,origins]

Allows setting origins to allow for unsafe requests. See Django docs

CSRF_TRUSTED_ORIGINS = []

Cors origins

default False - options: False, True

By default, cross-origin resource sharing is disabled. Enabling this will allow access to your resources from other domains. Please read the docs carefully before enabling this.

CORS_ALLOW_ALL_ORIGINS = True

Session Cookies

Django session cookie settings. Can be changed to allow a single django application to authenticate several applications when running under the same database.

SESSION_COOKIE_DOMAIN=.example.com
SESSION_COOKIE_NAME=sessionid # use this only to not interfere with non unified django applications under the same top level domain

Features

Some features can be enabled/disabled on a server level because they might change the user experience significantly, they might be unstable/beta or they have performance/security implications.

Captcha

If you allow signing up to your instance you might want to use a captcha to prevent spam. Tandoor supports HCAPTCHA which is supposed to be a privacy-friendly captcha provider. See HCAPTCHA website for more information and to acquire your sitekey and secret.

HCAPTCHA_SITEKEY=
HCAPTCHA_SECRET=

Metrics

Enable serving of prometheus metrics under the /metrics path

Danger

The view is not secured (as per the prometheus default way) so make sure to secure it through your web server.

ENABLE_METRICS=0

Tree Sorting

default 0 - options 0, 1

By default SORT_TREE_BY_NAME is disabled this will store all Keywords and Food in the order they are created. Enabling this setting makes saving new keywords and foods very slow, which doesn't matter in most usecases. However, when doing large imports of recipes that will create new objects, can increase total run time by 10-15x Keywords and Food can be manually sorted by name in Admin This value can also be temporarily changed in Admin, it will revert the next time the application is started

Info

Disabling tree sorting is a temporary fix, in the future we might find a better implementation to allow tree sorting without the large performance impacts.

SORT_TREE_BY_NAME=0

PDF Export

default 0 - options 0, 1

Exporting PDF's is a community contributed feature to export recipes as PDF files. This requires the server to download a chromium binary and is generally implemented only rudimentary and somewhat slow depending on your server device.

See Export feature docs for additional information.

ENABLE_PDF_EXPORT=1

Depending on your jurisdiction you might need to provide any of the following URLs for your instance.

TERMS_URL=
PRIVACY_URL=
IMPRINT_URL=

Authentication

All configurable variables regarding authentication. Please also visit the dedicated docs page for more information.

Default Permissions

Configures if a newly created user (from social auth or public signup) should automatically join into the given space and default group.

This setting is targeted at private, single space instances that typically have a custom authentication system managing access to the data.

Danger

With public signup enabled this will give everyone access to the data in the given space

Warning

This feature might be deprecated in favor of a space join and public viewing system in the future

default 0 (disabled) - options 0, 1-X (space id)

When enabled will join user into space and apply group configured in SOCIAL_DEFAULT_GROUP.

SOCIAL_DEFAULT_ACCESS = 1

default guest - options guest, user, admin

SOCIAL_DEFAULT_GROUP=guest

Enable Signup

default 0 - options 0, 1

Allow everyone to create local accounts on your application instance (without an invite link) You might want to setup HCAPTCHA to prevent bots from creating accounts/spam.

Info

Social accounts will always be able to sign up, if providers are configured

ENABLE_SIGNUP=0

Social Auth

Allows you to set up external OAuth providers.

SOCIAL_PROVIDERS = allauth.socialaccount.providers.github, allauth.socialaccount.providers.nextcloud,

Remote User Auth

default 0 - options 0, 1

Allow authentication via the REMOTE-USER header (can be used for e.g. authelia).

Danger

Leave off if you don't know what you are doing! Enabling this without proper configuration will enable anybody to login with any username!

REMOTE_USER_AUTH=0

LDAP

LDAP based authentication is disabled by default. You can enable it by setting LDAP_AUTH to 1 and configuring the other settings accordingly. Please remove/comment settings you do not need for your setup.

LDAP_AUTH=
AUTH_LDAP_SERVER_URI=
AUTH_LDAP_BIND_DN=
AUTH_LDAP_BIND_PASSWORD=
AUTH_LDAP_USER_SEARCH_BASE_DN=
AUTH_LDAP_TLS_CACERTFILE=
AUTH_LDAP_START_TLS=

External Services

Email

Email Settings, see Django docs for additional information. Required for email confirmation and password reset (automatically activates if host is set).

EMAIL_HOST=
EMAIL_PORT=
EMAIL_HOST_USER=
EMAIL_HOST_PASSWORD=
EMAIL_USE_TLS=0
EMAIL_USE_SSL=0
# email sender address (default 'webmaster@localhost')
DEFAULT_FROM_EMAIL=

Optional settings (only copy the ones you need)

# prefix used for account related emails (default "[Tandoor Recipes] ")
ACCOUNT_EMAIL_SUBJECT_PREFIX=

S3 Object storage

If you want to store your users media files using an external storage provider supporting the S3 API's (Like S3, MinIO, ...) configure the following settings accordingly. As long as S3_ACCESS_KEY is not set, all object storage related settings are disabled.

See also Django Storages Docs for additional information.

Info

Settings are only named S3 but apply to all compatible object storage providers.

Required settings

S3_ACCESS_KEY=
S3_SECRET_ACCESS_KEY=
S3_BUCKET_NAME=

Optional settings (only copy the ones you need)

S3_REGION_NAME= # default none, set your region might be required
S3_QUERYSTRING_AUTH=1 # default true, set to 0 to serve media from a public bucket without signed urls
S3_QUERYSTRING_EXPIRE=3600 # number of seconds querystring are valid for
S3_ENDPOINT_URL= # when using a custom endpoint like minio
S3_CUSTOM_DOMAIN= # when using a CDN/proxy to S3 (see https://github.com/TandoorRecipes/recipes/issues/1943)

FDC Api

The FDC Api is used to automatically load nutrition information from the FDC Nutrition Database. The default DEMO_KEY is limited to 30 requests / hour or 50 requests / day. If you want to do many requests to the FDC API you need to get a (free) API key here.

FDC_API_KEY=DEMO_KEY

Debugging/Development settings

Warning

These settings should not be left on in production as they might provide additional attack surfaces and information to adversaries.

Debug

default 0 - options: 0, 1

Info

Please enable this before posting logs anywhere to ask for help.

Setting to 1 enables several django debug features and additional logs (see docs).

DEBUG=0

Debug Toolbar

default 0 - options: 0, 1

Set to 1 to enable django debug toolbar middleware. Toolbar only shows if DEBUG=1 is set and the requesting IP is in INTERNAL_IPS. See Django Debug Toolbar Docs.

DEBUG_TOOLBAR=0

SQL Debug

default 0 - options: 0, 1

Set to 1 to enable additional query output on the search page.

SQL_DEBUG=0

Gunicorn Log Level

default info - options: see Gunicorn Docs

Increase or decrease the logging done by gunicorn (the python wsgi application).

 GUNICORN_LOG_LEVEL="debug"

Default User Preferences

Having default user preferences is nice so that users signing up to your instance already have the settings you deem appropriate.

Fractions

default 0 - options: 0,1

The default value for the user preference 'fractions' (showing amounts as decimals or fractions).

FRACTION_PREF_DEFAULT=0

Comments

default 1 - options: 0,1

The default value for the user preference 'comments' (enable/disable commenting system)

COMMENT_PREF_DEFAULT=1

default 1 - options: 0,1

The default value for the user preference 'sticky navigation' (always show navbar on top or hide when scrolling)

STICKY_NAV_PREF_DEFAULT=1

Max owned spaces

default 100 - options: 0-X

The default for the number of spaces a user can own. By setting to 0 space creation for users will be disabled. Superusers can always bypass this limit.

MAX_OWNED_SPACES_PREF_DEFAULT=100

Cosmetic / Preferences

Timezone

default Europe/Berlin - options: see timezone DB

Default timezone to use for database connections (see Django docs). Usually everything is converted to the users timezone so this setting doesn't really need to be correct.

TZ=Europe/Berlin

Default Theme

default 0 - options 1-X (space ID)

Tandoors appearance can be changed on a user and space level but unauthenticated users always see the tandoor default style. With this setting you can specify the ID of a space of which the appearance settings should be applied if a user is not logged in.

UNAUTHENTICATED_THEME_FROM_SPACE=

Force Theme

default 0 - options 1-X (space ID)

Similar to the Default theme but forces the theme upon all users (authenticated/unauthenticated) and all spaces

FORCE_THEME_FROM_SPACE=

Rate Limiting / Performance

Shopping auto sync

default 5 - options: 1-XXX

Users can set an amount of time after which the shopping list is automatically refreshed. This is the minimum interval users can set. Setting this to a low value will allow users to automatically refresh very frequently which might cause high load on the server. (Technically they can obviously refresh as often as they want with their own scripts)

SHOPPING_MIN_AUTOSYNC_INTERVAL=5

API Url Import throttle

default 60/hour - options: x/hour, x/day, x/minute, x/second

Limits how many recipes a user can import per hour. A rate limit is recommended to prevent users from abusing your server for (DDoS) relay attacks and to prevent external service providers from blocking your server for too many request.

DRF_THROTTLE_RECIPE_URL_IMPORT=60/hour

Default Space Limits

You might want to limit how many resources a user might create. The following settings apply automatically to newly created spaces. These defaults can be changed in the admin view after a space has been created.

If unset, all settings default to unlimited/enabled

SPACE_DEFAULT_MAX_RECIPES=0 # 0=unlimited recipes
SPACE_DEFAULT_MAX_USERS=0 # 0=unlimited users per space
SPACE_DEFAULT_MAX_FILES=0 # Maximum file storage for space in MB. 0 for unlimited, -1 to disable file upload.
SPACE_DEFAULT_ALLOW_SHARING=1 # Allow users to share recipes with public links

Export file caching

default 600 - options 1-X

Recipe exports are cached for a certain time (in seconds) by default, adjust time if needed

EXPORT_FILE_CACHE_DURATION=600
