# Advanced Configuration
# Best Practice: Use a docker network
For those who have a few of their upstream services running in docker on the same docker host as NPM, here's a trick to secure things a bit better. By creating a custom docker network, you don't need to publish ports for your upstream services to all of the docker host's interfaces.
Create a network, ie "scoobydoo":
docker network create scoobydoo
Then add the following to the
docker-compose.yml file for both NPM and any other
services running on this docker host:
networks: default: external: name: scoobydoo
Let's look at a Portainer example:
version: '3' services: portainer: image: portainer/portainer privileged: true volumes: - './data:/data' - '/var/run/docker.sock:/var/run/docker.sock' restart: always networks: default: external: name: scoobydoo
Now in the NPM UI you can create a proxy host with
portainer as the hostname,
9000 as the port. Even though this port isn't listed in the docker-compose
file, it's "exposed" by the portainer docker image for you and not available on
the docker host outside of this docker network. The service name is used as the
hostname, so make sure your service names are unique when using the same network.
# Docker Secrets
This image supports the use of Docker secrets to import from file and keep sensitive usernames or passwords from being passed or preserved in plaintext.
You can set any environment variable from a file by appending
__FILE (double-underscore FILE) to the environmental variable name.
version: "3.7" secrets: # Secrets are single-line text files where the sole content is the secret # Paths in this example assume that secrets are kept in local folder called ".secrets" DB_ROOT_PWD: file: .secrets/db_root_pwd.txt MYSQL_PWD: file: .secrets/mysql_pwd.txt services: app: image: 'jc21/nginx-proxy-manager:latest' restart: always ports: # Public HTTP Port: - '80:80' # Public HTTPS Port: - '443:443' # Admin Web Port: - '81:81' environment: # These are the settings to access your db DB_MYSQL_HOST: "db" DB_MYSQL_PORT: 3306 DB_MYSQL_USER: "npm" # DB_MYSQL_PASSWORD: "npm" # use secret instead DB_MYSQL_PASSWORD__FILE: /run/secrets/MYSQL_PWD DB_MYSQL_NAME: "npm" # If you would rather use Sqlite uncomment this # and remove all DB_MYSQL_* lines above # DB_SQLITE_FILE: "/data/database.sqlite" # Uncomment this if IPv6 is not enabled on your host # DISABLE_IPV6: 'true' volumes: - ./data:/data - ./letsencrypt:/etc/letsencrypt depends_on: - db db: image: jc21/mariadb-aria restart: always environment: # MYSQL_ROOT_PASSWORD: "npm" # use secret instead MYSQL_ROOT_PASSWORD__FILE: /run/secrets/DB_ROOT_PWD MYSQL_DATABASE: "npm" MYSQL_USER: "npm" # MYSQL_PASSWORD: "npm" # use secret instead MYSQL_PASSWORD__FILE: /run/secrets/MYSQL_PWD volumes: - ./data/mysql:/var/lib/mysql
# Disabling IPv6
On some docker hosts IPv6 may not be enabled. In these cases, the following message may be seen in the log:
Address family not supported by protocol
The easy fix is to add a Docker environment variable to the Nginx Proxy Manager stack:
environment: DISABLE_IPV6: 'true'
# Custom Nginx Configurations
If you are a more advanced user, you might be itching for extra Nginx customizability.
NPM has the ability to include different custom configuration snippets in different places.
You can add your custom configuration snippet files at
/data/nginx/custom as follow:
/data/nginx/custom/root.conf: Included at the very end of nginx.conf
/data/nginx/custom/http.conf: Included at the end of the main http block
/data/nginx/custom/stream.conf: Included at the end of the main stream block
/data/nginx/custom/server_proxy.conf: Included at the end of every proxy server block
/data/nginx/custom/server_redirect.conf: Included at the end of every redirection server block
/data/nginx/custom/server_stream.conf: Included at the end of every stream server block
/data/nginx/custom/server_stream_tcp.conf: Included at the end of every TCP stream server block
/data/nginx/custom/server_stream_udp.conf: Included at the end of every UDP stream server block
Every file is optional.
# X-FRAME-OPTIONS Header
You can configure the
value by specifying it as a Docker environment variable. The default if not specified is
... environment: X_FRAME_OPTIONS: "sameorigin" ...
