Options

This document lists the options that linkding can be configured with and explains how to use them in the individual install scenarios.

Using options

Docker

Options are passed as environment variables to the Docker container by using the -e argument when using docker run. For example:

docker run --name linkding -p 9090:9090 -d -e LD_DISABLE_URL_VALIDATION=True sissbruecker/linkding:latest

For multiple options, use one -e argument per option.

Docker-compose

For docker-compose options are configured using an .env file. Follow the docker-compose setup in the README and copy .env.sample to .env. Then modify the options in .env.

Manual setup

All options need to be defined as environment variables in the environment that linkding runs in.

List of options

LD_SUPERUSER_NAME

Values: String | Default = None

When set, creates an initial superuser with the specified username when starting the container. Does nothing if the user already exists.

See LD_SUPERUSER_PASSWORD on how to configure the respective password.

LD_SUPERUSER_PASSWORD

Values: String | Default = None

The password for the initial superuser. When left undefined, the superuser will be created without a usable password, which means the user can not authenticate using credentials / through the login form, and can only be authenticated using proxy authentication (see LD_ENABLE_AUTH_PROXY).

LD_DISABLE_BACKGROUND_TASKS

Values: True, False | Default = False

Disables background tasks, such as creating snapshots for bookmarks on the the Internet Archive Wayback Machine. Enabling this flag will prevent the background task processor from starting up, and prevents scheduling tasks. This might be useful if you are experiencing performance issues or other problematic behaviour due to background task processing.

LD_DISABLE_URL_VALIDATION

Values: True, False | Default = False

Completely disables URL validation for bookmarks. This can be useful if you intend to store non fully qualified domain name URLs, such as network paths, or you want to store URLs that use another protocol than http or https.

LD_REQUEST_TIMEOUT

Values: Integer as seconds | Default = 60

Configures the request timeout in the uwsgi application server. This can be useful if you want to import a bookmark file with a high number of bookmarks and run into request timeouts.

LD_SERVER_PORT

Values: Valid port number | Default = 9090

Allows to set a custom port for the UWSGI server running in the container. While Docker containers have their own IP address namespace and port collisions are impossible to achieve, there are other container solutions that share one. Podman, for example, runs all containers in a pod under one namespace, which results in every port only being allowed to be assigned once. This option allows to set a custom port in order to avoid collisions with other containers.

LD_CONTEXT_PATH

Values: String | Default = None

Allows configuring the context path of the website. Useful for setting up Nginx reverse proxy. The context path must end with a slash. For example: linkding/

LD_ENABLE_AUTH_PROXY

Values: True, False | Default = False

Enables support for authentication proxies such as Authelia. This effectively disables credentials-based authentication and instead authenticates users if a specific request header contains a known username. You must make sure that your proxy (nginx, Traefik, Caddy, ...) forwards this header from your auth proxy to linkding. Check the documentation of your auth proxy and your reverse proxy on how to correctly set this up.

Note that this automatically creates new users in the database if they do not already exist.

Enabling this setting also requires configuring the following options:

  • LD_AUTH_PROXY_USERNAME_HEADER - The name of the request header that the auth proxy passes to the proxied application (linkding in this case), so that the application can identify the user. Check the documentation of your auth proxy to get this information. Note that the request headers are rewritten in linkding: all HTTP headers are prefixed with HTTP_, all letters are in uppercase, and dashes are replaced with underscores. For example, for Authelia, which passes the Remote-User HTTP header, the LD_AUTH_PROXY_USERNAME_HEADER needs to be configured as HTTP_REMOTE_USER.
  • LD_AUTH_PROXY_LOGOUT_URL - The URL that linkding should redirect to after a logout. By default, the logout redirects to the login URL, which means the user will be automatically authenticated again. Instead, you might want to configure the logout URL of the auth proxy here.

LD_CSRF_TRUSTED_ORIGINS

Values: String | Default = None

List of trusted origins / host names to allow for POST requests, for example when logging in, or saving bookmarks. For these type of requests, the Origin header must match the Host header, otherwise the request will fail with a 403 status code, and the message CSRF verification failed.

This option allows to declare a list of trusted origins that will be accepted even if the headers do not match. This can be the case when using a reverse proxy that rewrites the Host header, such as Nginx.

For example, to allow requests to https://linkding.mydomain.com, configure the setting to https://linkding.mydomain.com. Note that the setting must include the correct protocol (https or http), and must not include the application / context path. Multiple origins can be specified by separating them with a comma (,).

This setting is adopted from the Django framework used by linkding, more information on the setting is available in the Django documentation.

LD_DB_ENGINE

Values: postgres or sqlite | Default = sqlite

Database engine used by linkding to store data. Currently, linkding supports SQLite and PostgreSQL. By default, linkding uses SQLite, for which you don't need to configure anything. All the other database variables below are only required for configured PostgresSQL.

LD_DB_DATABASE

Values: String | Default = linkding

The name of the database.

LD_DB_USER

Values: String | Default = linkding

The name of the user to connect to the database server.

LD_DB_PASSWORD

Values: String | Default = None

The password of the user to connect to the database server. The password must be configured when using a database other than SQLite, there is no default value.

LD_DB_HOST

Values: String | Default = localhost

The hostname or IP of the database server.

LD_DB_PORT

Values: Integer | Default = None

The port of the database server. Should use the default port if left empty, for example 5432 for PostgresSQL.

LD_FAVICON_PROVIDER

Values: String | Default = https://t1.gstatic.com/faviconV2?url={url}&client=SOCIAL&type=FAVICON

The favicon provider used for downloading icons if they are enabled in the user profile settings. The default provider is a Google service that automatically detects the correct favicon for a website, and provides icons in consistent image format (PNG) and in a consistent image size.

This setting allows to configure a custom provider in form of a URL. When calling the provider with the URL of a website, it must return the image data for the favicon of that website. The configured favicon provider URL must contain a {url} placeholder that will be replaced with the URL of the website for which to download the favicon. See the default URL for an example.
