Install an external library with docker compose

Can you please show your docker-compose file?
npm install hello-world-npm should be inside a custom Dockerfile which extends the standard n8n image.

The result should be like this

A part of Docker-compose.yml:

  n8n:
    #image: n8nio/n8n
    build:
      context: .
      dockerfile: Dockerfile-n8n
    user: "1000:1000"
    restart: always
    depends_on:
      - db-n8n
    ports:
      - "127.0.0.1:5678:5678"
    labels:
      <SOME TRAEFIK STUFF IF USING TRAEFIK AS REVERSE-PROXY>
    environment:
      <SOME ENV VARIABLES HERE>

      - NODE_FUNCTION_ALLOW_BUILTIN
      - NODE_FUNCTION_ALLOW_EXTERNAL
    volumes:
      - ${DATA_FOLDER}/.n8n:/home/node/.n8n

And then Dockerfile-n8n. Note that I install both system libs + npm packages. System libs are available immediately via Execute Command Node:

ARG tag=latest
FROM n8nio/n8n:$tag
USER root

RUN apk --update add sshpass openssh imagemagick libwebp libwebp-tools ghostscript poppler-utils curl curl-dev libcurl linux-headers g++ gfortran libxml2 libxml2-dev ffmpeg openjdk8-jre libreoffice
RUN apk add --no-cache msttcorefonts-installer fontconfig
RUN update-ms-fonts

RUN npm install -g pdf-image pdf2pic minify [email protected] nunjucks xlsx-template

USER node

Finally, don’t forget about .env file:

NODE_FUNCTION_ALLOW_BUILTIN=*
NODE_FUNCTION_ALLOW_EXTERNAL=luxon,pdf-image,pdf2pic,minify,easy-template-x,pca-js,nunjucks,xlsx-template
