Portracker is a self-hosted, open-source tool for real-time port monitoring and network service discovery. It automatically scans systems to detect services and ports, preventing deployment failures due to conflicts. With a lightweight, single-process design and embedded SQLite database, it supports Docker, offers peer-to-peer monitoring, hierarchical server grouping, and a modern, responsive UI. Deployable via Docker and licensed under MIT, it’s ideal for streamlined network visibility and port management. In this step by step guide I will show you how to install Portracker on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Portracker v.1.0.2 release.

• STEP 2

Install Portainer using my step by step guide. If you already have Portainer installed on your Synology NAS, skip this STEP. Attention: Make sure you have installed the latest Portainer version.

• STEP 3

Go to File Station and open the docker folder. Inside the docker folder, create one new folder and name it portracker. Follow the instructions in the image below.
Note: Be careful to enter only lowercase, not uppercase letters.

• STEP 4

Log into Portainer using your username and password. On the left sidebar in Portainer, click on Stacks then + Add stack. Follow the instructions in the image below.

• STEP 5

In the Name field type in portracker. Follow the instructions in the image below.

Note: Copy Paste the code below in the Portainer Stacks Web editor.

services:
  portracker:
    image: mostafawahied/portracker:latest
    container_name: Portracker
    healthcheck:
      test: ["CMD-SHELL", "nc -z 127.0.0.1 4999 || exit 1"]
      interval: 10s
      timeout: 5s
      retries: 3
      start_period: 90s
    network_mode: host
    volumes:
      - /volume1/docker/portracker:/data:rw
      - /var/run/docker.sock:/var/run/docker.sock:ro
    environment:
       DATABASE_PATH: /data/portracker.db
       PORT: 4999
    restart: on-failure:5

• STEP 6

Scroll down on the page until you see a button named Deploy the stack. Click on it. Follow the instructions in the image below. The installation process can take up to a few minutes. It will depend on your Internet speed connection.

• STEP 7

If everything goes right, you will see the following message at the top right of your screen: “Success Stack successfully deployed“.

• STEP 8

🟢Please Support My work by Making a Donation. Almost 99,9% of the people that install something using my guides forget to support my work, or just ignore STEP 1. I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.

• STEP 9

The installation process can take up to a few seconds/minutes. It will depend on your Internet speed connection. Now open your browser and type in http://Synology-ip-address:4999 If everything goes right, you will see the Portracker main page. ⚠️Warning: Wait some minutes until you are able too see this page. When you launch the application for the first time, you will see a blurred interface because the port scan is ongoing.

Enjoy Portracker!
