n8n-nodes-google-pubsub

This package provides nodes for n8n to work with Google Pub/Sub.

Installation

In a local NPM installation

npm i n8n-nodes-google-pubsub

The nodes should be automatically discovered by n8n.

In a global installation

npm i -g n8n-nodes-google-pubsub

You should then set the N8N_CUSTOM_EXTENSIONS variable to the path of the modules, e.g. on Ubuntu:

export N8N_CUSTOM_EXTENSIONS="/usr/local/lib/node_modules/n8n-nodes-google-pubsub"

In a Docker image

You'll have to spin your own Dockerfile that builds from the official n8n image:

FROM n8nio/n8n

USER root

RUN npm_config_user=root npm install -g n8n-nodes-google-pubsub

ENV N8N_CUSTOM_EXTENSIONS "/usr/local/lib/node_modules/n8n-nodes-google-pubsub"

Usage

Credentials

The credentials are based on the standard Google credentials. The easiest way is to setup a service account with the required permissions to work with Pub/Sub.
