Installer codes

The installer code is used to identify the way InvenTree was installed. If you vendor InvenTree, you can and should set the installer code to your own value to make sure debugging goes smoothly.

Code	Description	Official
PKG	Installed using a package manager	Yes
GIT	Installed using git	Yes
DOC	Installed using docker	Yes
DIO	Installed using digital ocean marketplace[^1]	No

[^1]: Starting with fresh installs of 0.12.0 this code is set. Versions installed before 0.12.0 do not have this code set even after upgrading to 0.12.0.

Authentication

LDAP

You can link your InvenTree server to an LDAP server.

Important

This feature is currently only available for docker installs.

Next you can start configuring the connection. Either use the config file or set the environment variables.

config key	ENV Variable	Description
ldap.enabled	INVENTREE_LDAP_ENABLED	Set this to True to enable LDAP.
ldap.debug	INVENTREE_LDAP_DEBUG	Set this to True to activate debug mode, useful for troubleshooting ldap configurations.
ldap.server_uri	INVENTREE_LDAP_SERVER_URI	LDAP Server URI, e.g. ldaps://example.org
ldap.start_tls	INVENTREE_LDAP_START_TLS	Enable TLS encryption over the standard LDAP port, see. (You can set TLS options via ldap.global_options)
ldap.bind_dn	INVENTREE_LDAP_BIND_DN	LDAP bind dn, e.g. cn=admin,dc=example,dc=org
ldap.bind_password	INVENTREE_LDAP_BIND_PASSWORD	LDAP bind password
ldap.search_base_dn	INVENTREE_LDAP_SEARCH_BASE_DN	LDAP search base dn, e.g. cn=Users,dc=example,dc=org
ldap.user_dn_template	INVENTREE_LDAP_USER_DN_TEMPLATE	use direct bind as auth user, ldap.bind_dn and ldap.bin_password is not necessary then, e.g. uid=%(user)s,dc=example,dc=org
ldap.global_options	INVENTREE_LDAP_GLOBAL_OPTIONS	set advanced options as dict, e.g. TLS settings. For a list of all available options, see python-ldap docs. (keys and values starting with OPT_ get automatically converted to python-ldap keys)
ldap.search_filter_str	INVENTREE_LDAP_SEARCH_FILTER_STR	LDAP search filter str, default: uid=%(user)s
ldap.user_attr_map	INVENTREE_LDAP_USER_ATTR_MAP	LDAP <-> Inventree user attribute map, can be json if used as env, in yml directly specify the object. default: {"first_name": "givenName", "last_name": "sn", "email": "mail"}
ldap.always_update_user	INVENTREE_LDAP_ALWAYS_UPDATE_USER	Always update the user on each login, default: true
ldap.cache_timeout	INVENTREE_LDAP_CACHE_TIMEOUT	cache timeout to reduce traffic with LDAP server, default: 3600 (1h)
ldap.group_search	INVENTREE_LDAP_GROUP_SEARCH	Base LDAP DN for group searching; required to enable group features
ldap.require_group	INVENTREE_LDAP_REQUIRE_GROUP	If set, users must be in this group to log in to InvenTree
ldap.deny_group	INVENTREE_LDAP_DENY_GROUP	If set, users must not be in this group to log in to InvenTree
ldap.user_flags_by_group	INVENTREE_LDAP_USER_FLAGS_BY_GROUP	LDAP group to InvenTree user flag map, can be json if used as env, in yml directly specify the object. See config template for example, default: {}

Tracing support

Starting with 0.14.0 InvenTree supports sending traces, logs and metrics to OpenTelemetry compatible endpoints (both HTTP and gRPC). A list of vendors is available on the project site. This can be used to track usage and performance of the InvenTree backend and connected services like databases, caches and more.

config key	ENV Variable	Description
tracing.enabled	INVENTREE_TRACING_ENABLED	Set this to True to enable OpenTelemetry.
tracing.endpoint	INVENTREE_TRACING_ENDPOINT	General endpoint for information (not specific trace/log url)
tracing.headers	INVENTREE_TRACING_HEADERS	HTTP headers that should be send with every request (often used for authentication). Format as a dict.
tracing.auth.basic	INVENTREE_TRACING_AUTH_BASIC	Auth headers that should be send with every requests (will be encoded to b64 and overwrite auth headers)
tracing.is_http	INVENTREE_TRACING_IS_HTTP	Are the endpoints HTTP (True, default) or gRPC (False)
tracing.append_http	INVENTREE_TRACING_APPEND_HTTP	Append default url routes (v1) to tracing.endpoint
tracing.console	INVENTREE_TRACING_CONSOLE	Print out all exports (additionally) to the console for debugging. Do not use in production
tracing.resources	INVENTREE_TRACING_RESOURCES	Add additional resources to all exports. This can be used to add custom tags to the traces. Format as a dict.

Multi Site Support

If your InvenTree instance is used in a multi-site environment, you can enable multi-site support. Note that supporting multiple sites is well outside the scope of most InvenTree installations. If you know what you are doing, and have a good reason to enable multi-site support, you can do so by setting the INVENTREE_SITE_MULTI environment variable to True.

Django Documentation

For more information on multi-site support, refer to the Django documentation.

Environment Variable	Config Key	Description	Default
INVENTREE_SITE_MULTI	site_multi	Enable multiple sites	False
INVENTREE_SITE_ID	site_id	Specify a fixed site ID	Not specified
