# n8n-hosting

This is a fork of the [n8n-hosting](https://github.com/n8n-io/n8n-hosting) GitHub project, and is a skeleton for building a Docke Compose environment for self-hosting an n8n instance in your environment to support the editor UI and worker nodes that run your jobs.

It has been specialized to expose ecosystem (NPM) modules and our custom code to an n8n environment. Our requirement for external modules and custom code in our workflows is what requires us (and you) to self-host n8n and run it in your environment.

## Our Changes

## Getting Started

1. Clone [dtp-n8n-hosting](https://git.digitaltelepresence.com/digital-telepresence/dtp-n8n-hosting) to a directory on your host/server.

And feel free to fork it. We are pulling updates from our upstream, and you can pull updates directly from them, or from us.

2. Run `npm install` from the root of the project.

This will create your `node_modules` directory to receive external modules needed by DTP Newsroom.

3. Customize [.env](./docker-compose/withPostgres/.env)

```bash
cd docker-compose/withPostgres
cp .env.example .env
```

You'll want to customize the values specified to match your requirements in your environment. This setup will run a PostgreSQL instance in a container, and directly access it

```yml
POSTGRES_USER=changeUser
POSTGRES_PASSWORD=changePassword
POSTGRES_DB=n8n

POSTGRES_NON_ROOT_USER=changeUser
POSTGRES_NON_ROOT_PASSWORD=changePassword
```

4. Customize [docker-compose.yml](./docker-compose/withPostgres/docker-compose.yml)

```yml
environment:
  - WEBHOOK_URL=https://n8n.digitaltelepresence.com/
  - NODE_FUNCTION_ALLOW_BUILTIN=*
  - NODE_FUNCTION_ALLOW_EXTERNAL=dayjs,numeral
```

```yml
volumes:
  - /home/dtp/live/dtp-n8n-hosting/node_modules/dayjs:/usr/local/lib/node_modules/dayjs
  - /home/dtp/live/dtp-n8n-hosting/node_modules/numeral:/usr/local/lib/node_modules/numeral
```

5. Run `docker-compose up -d`

6. Visit http://localhost:5678/ to access n8n.

This will create a `node_modules` directory in the project directory. This is normal, and required. The directory will contain a subdirectory for each module added.
