Docker Development Server¶
You can use docker to launch and manage a development server, in a similar fashion to managing a production server.
The InvenTree dockerfile (
./Dockerfile) uses a multi-stage build process to allow both production and development setups from the same image.
There are some key differences compared to the docker production setup:
- The docker image is built locally, rather than being downloaded from DockerHub
- The docker image points to the source code on your local machine (mounted as a 'volume' in the docker container)
- The django webserver is used, instead of running behind Gunicorn
- The server will automatically reload when code changes are detected
Static and Media Files
The development server runs in DEBUG mode, and serves static and media files natively.
The following setup guide starts a development server which will reload "on the fly" as changes are made to the source code. This is designed for programmers and developers who wish to add and test new InvenTree features.
Persistent data (such as the stored database, media files, configuration files, etc) will be stored in the
./data directory (relative to the InvenTree source code directory).
- This directory is automatically created when you launch InvenTree via docker
- This directory is excluded from git version tracking
To get "up and running" with a development environment, complete with a set of demo data to work with, run the following commands:
git clone https://github.com/inventree/InvenTree.git && cd InvenTree docker compose run inventree-dev-server invoke install docker compose run inventree-dev-server invoke setup-test --dev docker compose up -d
You can then view the development server at http://localhost:8000
For a more in-depth setup guide, continue reading below!
Development Setup Guide¶
To get started with an InvenTree development setup, follow the simple steps outlined below. Before continuing, ensure that you have completed the following steps:
- Downloaded the InvenTree source code to your local machine
- Installed docker on your local machine (install Docker Desktop on Windows)
- Have a terminal open to the root directory of the InvenTree source code
Edit Environment Variables (Optional)¶
If desired, the user may edit the environment variables, located in the
This step is optional
This step can be skipped, as the default variables will work just fine!
You may also wish to change the database username (
INVENTREE_DB_USER) and password (
INVENTREE_DB_PASSWORD) from their default values
Perform Initial Setup¶
Perform the initial database setup by running the following command:
docker compose run inventree-dev-server invoke update
If this is the first time you are configuring the development server, this command will build a development version of the inventree docker image.
This command also performs the following steps:
- Ensure required python packages are installed
- Perform the required schema updates to create the required database tables
- Update translation files
- Collect all required static files into a directory where they can be served by nginx
Grab a coffee
This initial build process may take a few minutes!
Import Demo Data¶
To fill the database with a demo dataset, run the following command:
docker compose run inventree-dev-server invoke setup-test --dev
Start Docker Containers¶
Now that the database has been created, and migrations applied, we are ready to launch the InvenTree containers:
docker compose up -d
Create Admin Account¶
If you are creating the initial database, you need to create an admin (superuser) account for the database. Run the command below, and follow the prompts:
Containers must be running
invoke superuser command to execute properly, ensure you have run the
docker compose up -d command.
docker compose run inventree-dev-server invoke superuser
This command launches the remaining containers:
inventree-dev-server- InvenTree web server
inventree-dev-worker- Background worker
Check that the server is running at http://localhost:8000. The server may take a few minutes to be ready.
Running commands in the container¶
docker compose run [...] commands creates a new container to run this specific command.
This will eventually clutter your docker with many dead containers that take up space on the system.
You can access the running containers directly with the following:
docker exec -it inventree-dev-server /bin/bash
You then run the following to access the virtualenv:
This sets up a bash terminal where you can run
invoke commands directly.
invoke test in your currently active inventree-dev-server container may result in tests taking longer than usual.
Cleaning up old containers¶
If you have Docker Desktop installed, you will be able to remove containers directly in the GUI.
Your active containers are grouped under "inventree" in Docker Desktop.
The main dev-server, dev-db, and dev-worker containers are all listed without the "inventree" prefix.
One time run containers, like those executed via
docker compose run [...] are suffixed with
run-1a2b3c4d5e6f where the hex string varies.
To remove such containers, either click the garbage bin on the end of the line, or mark the containers, and click the delete button that shows up. This is the recommended procedure for container cleanup.
Advanced users only
This section requires good knowledge of Docker and how it operates. Never perform these commands if you do not understand what they do
If you're running a container with the general boilerplate commands used with invoke (invoke test, invoke update, etc) and no custom parameters or execution, you can add the
--rm flag to
docker compose run, and the container will delete itself when it goes down.
Do note that any data not stored in a volume, i.e. only in the container, will be lost when the container stops.
To clean out old containers using the command line, follow this guide:
Run the following command:
docker ps -a --filter status=exited
This gives you a list of all stopped containers. Find the containers you wish to delete, copy the container IDs and add them to this command:
docker rm [ID1] [ID2] [IDn]
Execute at own risk
The command below does not forgive errors. Execute this only if you know what you're doing
Running this command will remove all stopped one-time run InvenTree containers matching parameters:
docker container prune --filter label="com.docker.compose.oneoff=True" --filter label="com.docker.compose.service=inventree-dev-server"
The following output will appear:
WARNING! This will remove all stopped containers. Are you sure you want to continue? [y/N] y Deleted Containers: [IDs of any container that was deleted, one per line]
Once initial setup is complete, stopping and restarting the services is much simpler:
Stop InvenTree Services¶
To stop the InvenTree development server, simply run the following command:
docker compose down
Start InvenTree Services¶
To start the InvenTree development server, simply run the following command:
docker compose up -d
Restart InvenTree Services¶
A restart cycle is as simple as:
docker compose restart
Editing InvenTree Source¶
Any changes made to the InvenTree source code are automatically detected by the services running under docker.
Thus, you can freely edit the InvenTree source files in your editor of choice.
Any updates which require a database schema change must be reflected in the database itself.
To run database migrations inside the docker container, run the following command:
docker compose run inventree-dev-server invoke update
Docker Image Updates¶
Occasionally, the docker image itself may receive some updates. In these cases, it may be required that the image is rebuilt. To perform a complete rebuild of the InvenTree development image from local source, run the following command:
docker compose build --no-cache
