How To Install Netbox IPAM in Docker Containers

Netbox is a free and open-source tool used to manage and document computer networks via the web. Netbox IPAM is written in Django. It helps ease the task of creating virtual implementations of devices in a data center which initially were being done on paper. The amazing features of Netbox IPAM include the following:

  • Vlan Management
  • VRF Management
  • IPAM – IP Address Management
  • CIM – Data Center Infrastructure Management
  • Circuit Provider Management
  • Multi-Site (tenancy)
  • Single Converged Database
  • Rack Elevation
  • Report Alert
  • Connection Management – Interfaces/Console/Power
  • Customization Header For Logo’s etc

Install Netbox

The first thing to do is the installation of Docker. To do this, open a terminal window and issue the following commands:

## On Debian/Ubuntu
sudo apt update && sudo apt upgrade
sudo apt install curl vim git

## On RHEL/CentOS/RockyLinux 8
sudo yum -y update
sudo yum -y install curl vim git

## On Fedora
sudo dnf update
sudo dnf -y install curl vim git

Install Docker with the command:

sudo apt-get install docker.io -y

or you can check previous post

Add your user to the docker group with the command:

sudo usermod -aG docker $USER
newgrp docker

Log out and log back in to the server. Install docker-compose with the command:

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

Change the permission of the docker-compose command with the command:

sudo chmod +x /usr/local/bin/docker-compose

Start the docker daemon with the command

sudo systemctl start docker

Enable the docker daemon with the command

sudo systemctl enable docker

Provision the Netbox IPAM server

All the components needed to build Netbox as a docker container are provided in the Github repository. Now git clone the Netbox docker file as below.

git clone -b release https://github.com/netbox-community/netbox-docker.git

go to Netbox directory

cd netbox-docker

Modify the docker-compose.yml from the docker-compose.override.yml.example file as below.

tee docker-compose.override.yml <<EOF
version: '3.4'
services:
  netbox:
    ports:
      - 8000:8080
EOF

Now we are set to start our docker container. But first, pull the required images for Netbox, PostgreSQL, Redis e.t.c

docker-compose pull

Several images will be pulled as below

If you have a firewall enabled, allow port 8000 as below

##For Firewalld
sudo firewall-cmd --zone=public --add-port=8000/tcp --permanent
sudo firewall-cmd --reload

##For UFW
sudo ufw allow 8000/tcp

Access the Netbox IPAM tool Web UI

Everything is set, we can now proceed and access the Netbox IPAM web UI with the URL http://Hostname:8000 or http://IP_Address:8000.

In case you want to stop all the running containers, run the below command:

docker-compose stop

You can remove the containers as below.

docker-compose stop && docker-compose rm

hope this article will help you 🙂
