Warning
Importing pandas in the Python Code node fails with a security violation in n8n 2.25.x - 2.27.x.
Stay in 2.23.4 or update directly to 2.28.4+ which introduced N8N_RUNNERS_ALLOW_TRANSITIVE_IMPORTS.
Click here to check for the issue
n8n v2 queue mode with separated task runner and worker. Integrated with PostgreSQL and Redis.
Rebuild task runner with numpy and pandas using Dockerfile and also enabled blocked nodes with NODES_EXCLUDE="[]"
Clone this repo
git clone https://github.com/tobing/n8n-v2-with-numpy-pandas.git
cd n8n-v2-with-numpy-pandas
To start n8n simply start docker-compose by executing the following command in the current folder.
IMPORTANT: Change the default users and passwords in the .env file!
docker compose up -d --build
To stop it execute:
docker-compose stop
Verify if n8n, worker and task runner images are the same version:
docker inspect n8n-main n8n-worker n8n-custom-runner | grep image.version
To access it, open with web browser:
http://localhost:5678
For custom domain modify these lines in docker-compose.yaml
- VUE_APP_URL_BASE_API=http://localhost:5678/
- N8N_EDITOR_BASE_URL=http://localhost:5678/
- WEBHOOK_URL=http://localhost:5678/
The default name of the database, user and password for PostgreSQL and also n8n version can be changed in the .env file in the current directory.
External packages for task runner can be modified with Dockerfile and n8n-task-runners.json inside n8n-custom-runner
Task runner included these external packages:
NODE: moment,uuid,axios,cheerio,form-data,node-fetch,csv-parse
PYTHON: numpy,pandas
To verify the external packages working properly, import n8n-workflow.json from verify-external-modules to n8n then execute workflow.
The workflow has 3 nodes. Manual trigger, Node Modules Test and Python Modules Test.
