USER root
RUN cd /opt/runners/task-runner-javascript && pnpm add moment uuid
RUN cd /opt/runners/task-runner-python && uv pip install numpy requests
COPY n8n-task-runners.json /etc/n8n-task-runners.json
USER runner

2) Create configuration file n8n-task-runners.json. You must also allowlist any first-party or third-party packages for use by the Code node.

NODE_FUNCTION_ALLOW_BUILTIN: comma-separated list of allowed node builtin modules.
NODE_FUNCTION_ALLOW_EXTERNAL: comma-separated list of allowed JS packages.
N8N_RUNNERS_STDLIB_ALLOW: comma-separated list of allowed Python standard library packages.
