Docker Installation Guide

The information on this page serves as useful theory and background information for setting up InvenTree using docker.

Docker Install

To jump right into the installation process, refer to the docker installation guide

Docker Theory

The most convenient method of installing and running InvenTree is to use the official docker image, available from docker-hub.

The InvenTree docker image contains all the required system packages, python modules, and configuration files for running a containerized InvenTree production installation.

Docker Compose

The InvenTree container requires linking with other docker containers (such as a database backend, and a file server) for complete operation. Refer to the docker compose instructions to get up and running

Check the version

Please make sure you are reading the STABLE documentation when using the stable docker image tags.

Assumed Knowledge

A very basic understanding of Docker and docker compose is assumed, for the following setup guides.

Tagged Images

Pre-built Docker images are available from dockerhub with the following tags:

Tag Description Relevant documentation to follow
inventree:stable The most recent stable release version of InvenTree stable docs
inventree:latest The most up-to-date development version of InvenTree. latest docs
inventree:tag Specific tagged images are built for each tagged release of InvenTree, e.g. inventree:0.7.3 Refer to specific InvenTree version

Docker Compose

The InvenTree docker image provides a containerized webserver, however it must be connected with other containers to function.

Environment Variables

InvenTree run-time configuration options described in the configuration documentation can be passed to the InvenTree container as environment variables. Using environment variables simplifies setup and improves portability.

Persistent Data

As docker containers are ephemeral, any persistent data must be stored in an external volume. To simplify installation / implementation, all external data are stored in a single volume, arranged as follows:

Media FIles

Uploaded media files are stored in the media/ subdirectory of the external data volume.

Static Files

Static files required by the webserver are stored in the static/ subdirectory of the external data volume.

Configuration File

As discussed in the configuration documentation, InvenTree run-time settings can be provided in a configuration file.

By default, this file will be created as config.yaml in the external data volume.

Secret Key

InvenTree uses a secret key to provide cryptographic signing for the application.

As specified in the configuration documentation this can be passed to the InvenTree application directly as an environment variable, or provided via a file.

By default, the InvenTree container expects the secret key file to exist as secret_key.txt (within the external data volume). If this file does not exist, it will be created and a new key will be randomly generated.

Same Key

Each InvenTree container instance must use the same secret key value, otherwise unexpected behavior will occur.


Plugins are supported natively when running under docker. There are two ways to install plugins when using docker:

  • Install via the plugins.txt file provided in the external data directory
  • Install into the plugins/ subdirectory in the external data directory

Docker Compose

docker compose is used to sequence all the required containerized processes.

Static and Media Files

The production docker compose configuration outlined on this page uses Caddy to serve static files and media files. If you change this configuration, you will need to ensure that static and media files are served correctly.

Refer to the Serving Files section for more details

SSL Certificates

The provided Caddyfile configuration file is setup to enable Automatic HTTPS by default! All you have to do is specify a https:// URL in the INVENTREE_SITE_URL variable.


The example docker compose file launches the following containers:

Container Description
inventree-db PostgreSQL database
inventree-server Gunicorn web server
inventree-worker django-q background worker
inventree-proxy Caddy file server and reverse proxy
inventree-cache redis cache (optional)

PostgreSQL Database

A PostgreSQL database container which requires a username:password combination (which can be changed). This uses the official PostgreSQL image.

Web Server

Runs an InvenTree web server instance, powered by a Gunicorn web server.

Background Worker

Runs the InvenTree background worker process. This spins up a second instance of the inventree container, with a different entrypoint command.

Proxy Server

Caddy working as a reverse proxy, separating requests for static and media files, and directing everything else to Gunicorn.

This container uses the official caddy image.

Nginx Proxy

An alternative is to run nginx as the reverse proxy. A sample configuration file is provided in the ./contrib/container/ source directory.

Redis Cache

Redis is used as cache storage for the InvenTree server. This provides a more performant caching system which can useful in larger installations.

This container uses the official redis image.

Redis on Docker

Docker adds an additional network layer - that might lead to lower performance than bare metal. To optimize and configure your redis deployment follow the official docker guide.

Enable Cache

While a redis container is provided in the default configuration, by default it is not enabled in the Inventree server. You can enable redis cache support by following the caching configuration guide

Data Volume

InvenTree stores any persistent data (e.g. uploaded media files, database data, etc) in a volume which is mapped to a local system directory. The location of this directory must be configured in the .env file, specified using the INVENTREE_EXT_VOLUME variable.

Data Directory

Make sure you change the path to the local directory where you want persistent data to be stored.

Common Issues

Volume Mapping

When configuring a docker install, sometimes a misconfiguration can cause peculiar issues where it seems that the installation is functioning correctly, but uploaded files and plugins do not "persist" across sessions. In such cases, the "mounted" volume has not mapped to a directory on your local filesystem. This may occur if you have tried multiple setup options without clearing existing volume bindings.

Start with a clean slate

To prevent such issues, it is recommended that you start with a "clean slate" if you have previously configured an InvenTree installation under docker.

If you have previously setup InvenTree, remove existing volume bindings using the following command:

docker volume rm -f inventree-production_inventree_data
