Manual

Requirements

Make sure you have the latest versions of Docker and Docker Compose installed on your machine.

• How install docker
• How install docker compose

Clone this repository or copy the files from this repository into a new folder.

Make sure to add your user to the docker group.

Configuration

download with

git clone https://github.com/damalis/full-stack-proxy-nginx-n8n-for-everyone-with-docker-compose.git

Open a terminal and cd to the folder in which docker-compose.yml is saved and run:

cd full-stack-proxy-nginx-n8n-for-everyone-with-docker-compose

Copy the example environment into .env

cp env.example .env

Edit the .env file to change values of

|LOCAL_TIMEZONE|DOMAIN_NAME|N8N_SUBDOMAIN|WEBUI_SUBDOMAIN|DIRECTORY_PATH|LETSENCRYPT_EMAIL| |DB_USER|DB_PASSWORD|DB_NAME|PGA_CONTROLPASS|SSL_SNIPPET|WHATSAPP_SUBDOMAIN|WHATSAPP_DASHBOARD_USERNAME| |WHATSAPP_DASHBOARD_PASSWORD|WHATSAPP_SWAGGER_USERNAME|WHATSAPP_SWAGGER_PASSWORD|

Variable	Value
LOCAL_TIMEZONE	to see local timezones
DIRECTORY_PATH	pwd at command line
SSL_SNIPPET	localhost	echo 'Generated Self-signed SSL Certificate at localhost'
	remotehost	certbot certonly --webroot --webroot-path /tmp/acme-challenge --rsa-key-size 4096 --non-interactive --agree-tos --no-eff-email --force-renewal --email ${LETSENCRYPT_EMAIL} -d ${DOMAIN_NAME} -d www.${DOMAIN_NAME} -d mail.${DOMAIN_NAME} -d ${N8N_SUBDOMAIN}.${DOMAIN_NAME} -d ${WEBUI_SUBDOMAIN}.${DOMAIN_NAME} -d ${WHATSAPP_SUBDOMAIN}.${DOMAIN_NAME}

Installation

Firstly: will create external volume

docker volume create --driver local --opt type=none --opt device=${PWD}/certbot --opt o=bind certbot-etc

Localhost ssl: Generate Self-signed SSL Certificate with guide mkcert repository.

docker compose up -d

then reloading for proxy ssl configuration

docker container restart proxy

The containers are now built and running. You should be able to access the n8n installation with the configured IP in the browser address. https://N8N_SUBDOMAIN.DOMAIN_NAME.

For convenience you may add a new entry into your hosts file.

Portainer

docker compose -f portainer-docker-compose.yml -p portainer up -d 

manage docker with Portainer is the definitive container management tool for Docker, Docker Swarm with it's highly intuitive GUI and API.

You can also visit https://DOMAIN_NAME:9001 to access portainer after starting the containers.

Usage

You could manage docker containers without command line with portainer.

Here’s a quick reference of commonly used Docker Compose commands

docker ps -a # Lists all containers managed by the compose file

docker compose start # Starts previously stopped containers

docker compose stop	# Stops all running containers

docker compose down	# Stops and removes containers, networks, etc.

docker compose down -v # Add --volumes to remove volumes explicitly

docker rm -f $(docker ps -a -q)	# Removes portainer and the other containers

docker volume rm $(docker volume ls -q)	# Removes all volumes

docker network prune # Remove all unused networks

docker system prune	# Removes unused data (containers, networks, images, and optionally volumes)

docker system prune -a # Removes all unused images, not just dangling ones

docker rmi $(docker image ls -q) # Removes portainer and the other images

docker container logs container_name_or_id # Shows logs from all services

Project from existing source

Copy all files into a new directory:

docker compose up -d # Starts services in detached mode (in the background)

n8n

n8n This page provides guidance on setting up n8n for both the Enterprise and Community self-hosted editions. The Community edition is free, the Enterprise edition isn't..

Mail

Send Email Node;

SMTP account: Host: mail; Port: 1025; SSL/TLS: off;

The authorize screen: |user: DB_USER| and |password: DB_PASSWORD| in the .env file.

Database

Postgres account; |Host: database; Port: 5432; Database: DB_NAME; User: DB_USER; Password: DB_PASSWORD| in the .env file.

Datavector

Postgres vector account; |Host: datavector; Port: 15432; Database: DB_NAME; User: DB_USER; Password: DB_PASSWORD| in the .env file.

pgAdmin

You can also visit https://DOMAIN_NAME:9090.

The login screen, |username: LETSENCRYPT_EMAIL and password: PGA_CONTROLPASS| in the .env file.

You don't see the login page in your browser;
pgAdmin runs as the pgadmin user (UID: 5050) in the pgadmin group (GID: 5050) in the container. You must ensure that all files are readable, and where necessary (e.g. the working/session directory) writeable for this user on the host machine.

sudo chown -R 5050:5050 ./pgadmin and/or sudo chown -R 5050:5050 ./certbot/live/DOMAIN_NAME

Ollama

Base URL; |http://ollama:11434|

Now you can pull a model: docker exec -it ollama ollama pull llama3
More models can be found on the https://ollama.com/library.

Open WEBUI

You can also visit https://WEBUI_SUBDOMAIN.DOMAIN_NAME.

Environment Variable Configuration

Proxy

Proxying is typically used to distribute the load among several servers, seamlessly show content from different websites, or pass requests for processing to application servers over protocols other than HTTP.

add or remove code in the ./proxy/templates/proxy.conf.template file for custom proxy configurations

https://docs.nginx.com/nginx/admin-guide/web-server/reverse-proxy/

Redis

Configuration; |Host: redis|

WhatsApp

API URL; |https://WHATSAPP_SUBDOMAIN.DOMAIN_NAME| and API Key; |WHATSAPP_API_KEY| in the .env file.

You can also visit https://WHATSAPP_SUBDOMAIN.DOMAIN_NAME/dashboard and swagger page - https://WHATSAPP_SUBDOMAIN.DOMAIN_NAME.

The authorize screen: |Username: DB_USER| and |Password: DB_PASSWORD| in the .env file.

Pipelines

Open WEBUI Manage Configurations https://WEBUI_SUBDOMAIN.DOMAIN_NAME:

Go to Admin Panel >> Settings -> Pipelines.

Select your pipeline and adjust valve values directly from the WebUI.
