Devcontainer
Devcontainer¶
Devcontainers are the easiest way to get into InvenTree development. You can either run them on your machine in vscode or use github codespaces.
Setup in vscode¶
Prerequisites¶
You need to make sure that you have the following tools installed before continuing.
- git is needed to clone the repository
- docker is needed to run the devcontainer
- vscode is needed to edit and debug code
Docker Containers¶
The InvenTree devcontainer setup will install two docker containers:
Container | Description |
---|---|
db | InvenTree database (postgresql) |
inventree | InvenTree server |
Setup/Installation¶
- Clone the repository (If you want to submit changes fork it and use the url to your fork in the next step)
git clone https://github.com/inventree/InvenTree.git
- Open vscode, navigate to the extensions sidebar and search for
ms-vscode-remote.remote-containers
. Click on install. - Open the cloned folder from above by clicking on
file > open folder
- vscode should now ask you if you'd like to reopen this folder in a devcontainer. Click
Reopen in Container
. If it does not ask you, open the command palette (CTRL/CMD+Shift+P) and search forReopen in Container
. This can take a few minutes until the image is downloaded, build and setup with all dependencies. - Open a new terminal from the top menu by clicking
Terminal > New Terminal
- The last line in your terminal should now show the text
(venv)
at the start of the line - You are done! You now should have a functioning InvenTree development installation
Setup in Codespaces¶
Open inventree/InvenTree with your browser and click on Code
, select the codespaces
tab and click on create codespace on current branch. This may can take a few minutes until your inventree development environment is setup.
Close the terminal
The appearing terminal which says Welcome to codespaces
is not using the virtual env. Close it and use a new terminal that will automatically connect to the venv for using commands.
Running tasks¶
Tasks can help you executing scripts. You can run them by open the command panel (CMD+Shift+P) and search for Run Task
. Then choose the desired task.
Setup demo dataset¶
If you need some demo test-data, run the setup-test
task. This will import an admin
user with the password inventree
. For more info on what this dataset contains see inventree/demo-dataset.
Setup a superuser¶
If you only need a superuser, run the superuser
task. It should prompt you for credentials.
Run background workers¶
If you need to process your queue with background workers, run the worker
task. This is a foreground task which will execute in the terminal.
Running InvenTree¶
You can either only run InvenTree or use the integrated debugger for debugging. Goto the Run and debug
side panel make sure InvenTree Server
is selected. Click on the play button on the left.
Debug with 3rd party
Sometimes you need to debug also some 3rd party packages. Just select InvenTree Servre - 3rd party
You can now set breakpoints and vscode will automatically pause execution if that point is hit. You can see all variables available in that context and evaluate some code with the debugger console at the bottom. Use the play or step buttons to continue execution.
React Frontend development
The React frontend requires additional steps to run. Refer to Platform UI / React
Plugin development¶
The easiest way for plugin developing is by using the InvenTree devcontainer. Just mount your plugin repository also into the devcontainer workspace and install it as pip editable package.
- To mount your plugin repo into the workspace, add this to your
.devcontainer/devcontainer.json
file. (Make sure that you don't commit it)"mounts": [ "source=/path/to/your/local/inventree-plugin,target=/workspaces/inventree-plugin,type=bind,consistency=cached" ],
- Add
/workspaces/inventree-plugin
to your vscode workspace folders by click onFile > Add folder to workspace…
. - Install your plugin as pip editable install by executing the following command in the venv.
pip install -e /workspaces/inventree-plugin
- Add InvenTree core code to Pylance IntelliSense path by adding the following file to your plugin repo
.vscode/settings.json
(Your path can be different depending on your setup):{ "python.analysis.extraPaths": ["/workspaces/InvenTree/InvenTree"] }
Your plugin should now be activateable from the InvenTree settings. You can also use breakpoints for debugging.
Troubleshooting¶
Your ssh-keys are not available in the devcontainer but are loaded to the active ssh-agent
on macOS¶
Make sure you enabled full disk access on macOS for vscode, otherwise your ssh-keys are not available inside the container (Ref: Automatically add SSH keys to ssh-agent [comment]).
You're not able to use your gpg-keys inside the devcontainer to sign commits on macOS¶
Make sure you have gnupg
and pinentry-mac
installed and set up correctly. Read this medium post for more info on how to set it up correctly.
Where are the database, media files, ... stored?¶
Backups, Commandhistory, media/static files, venv, plugin.txt, secret_key.txt, ... are stored in the dev
folder. If you want to start with a clean setup, you can remove that folder, but be aware that this will delete everything you already setup in InvenTree.
Performance Improvements¶
If you are running a devcontainer in Windows, you may experience some performance issues - particularly related to file system operations.
For a significant improvement in performance, the source code should be installed into the WSL 2 filesystem (not on your "Windows" filesystem). This will greatly improve file access performance, and also make the devcontainer much more responsive to file system changes.
You can also refer to the Improve disk performance guide for more information.
