Nginx Proxy Manager is a reverse proxy management tool that makes it possible to create configuration files, set up security exceptions, streams, and SSL certificates through a web interface. In this write-up, you can install Nginx Proxy Manager on a Ubuntu 20.04 server running docker.
Create the Nginx Proxy Manager directory in a widely accessible location like
# mkdir /opt/nginxproxymanager
Under the directory, create a new databases subdirectory.
# mkdir /opt/nginxproxymanager/databases
Create a new SQLite database file using the following command.
# touch /opt/nginxproxymanager/databases/nginxproxy.db
Exit the SQLite database console.
Control + d
Create a custom Docker network.
# docker network create nginxproxyman
The Nginx Proxy Manager network allows management and monitoring of attached containers.
Using a text editor, create and edit a
docker-compose.yml file in the main
# nano /opt/nginxproxymanager/docker-compose.yml
Enter the following configurations to the file:
version: "3" services: app: image: 'jc21/nginx-proxy-manager:latest' container_name: 'nginxproxymanager' restart: unless-stopped ports: - '80:80' - '443:443' - '81:81' environment: DB_SQLITE_FILE: "/data/database.sqlite" volumes: - ./data:/data - ./letsencrypt:/etc/letsencrypt networks: default: external: name: nginxproxyman
Nginx Proxy Manager listens on ports 80 and 443 for HTTP and HTTPS traffic, respectively. Port 81 provides access to the web management dashboard. To tighten server security, change the management port to a random combination.
Save and close the file.
Switch to the Nginx Proxy Manager directory.
# cd /opt/nginxproxymanager
Install Nginx Proxy Manager by starting docker-compose in detached mode.
# docker-compose up -d
Verify that Nginx Proxy Manager is up and running.
# docker ps
The command output should look like the one below:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES f3a37d391293 jc21/nginx-proxy-manager:latest "/init" 33 minutes ago Up 33 minutes 0.0.0.0:80-81->80-81/tcp, 0.0.0.0:443->443/tcp nginxproxymanager
If you use UFW (enabled by default), allow the following access ports through the server.
# ufw allow 80
# ufw allow 443
Allow the Nginx Proxy Manager web management dashboard.
# ufw allow 81
Visit your server's IP address and load the Nginx Proxy Manager web management dashboard on port 81.
Log in to the management dashboard with the following credentials:
Change your default username, email address, and password to secure the server.
To proxy and forward requests to a backend application, attach a docker container to the Nginx Proxy Manager network. For example, the following command creates a new ownCloud container attached to the
# docker run --network nginxproxyman --name owncloud -d owncloud:latest
Access the Nginx Proxy Manager web dashboard, and navigate to Hosts on the main navigation menu.
Click Add Proxy Host to enter a domain name, choose between HTTP or HTTPS scheme access, set up the target container name in the Forward Name/IP field, and toggle Save to continue.
Visit your domain name to confirm changes and start using the application.
You have successfully installed Nginx Proxy Manager on Ubuntu 20.04 and set up ownCloud as a backend application attached to the Docker network. For further information, refer to the following articles:
