This repository comprises a collection of scripts designed to facilitate the deployment of instances of the free5GC project.
The comprehensive documentation available on the project's official website is highly advisable for individuals new to free5GC to familiarize themselves with. The underlying processes are to be carefully studied, as the scripts are designed to replicate the steps outlined in the "Build free5GC from scratch" guide in an automated manner.
The scripts available on this repository have been based on free5GC's advanced setup instructions. However, instead of having two separate interfaces (one for remote access and other for general use), they have been designed considering a environment where the 5GC machine has only one network interface available.
In the course of my research, I've been utilizing the free5GC project. During the experimentation with this 5G Core (5GC) advanced setup and its associated Network Functions (NFs), I discovered an opportunity to streamline the installation process. By automating various installation tasks, I significantly reduced deployment time, optimizing efficiency and enabling a more agile research environment.
During the process of seeking a similar tool, I've found 301 repositories hosted on Github that had the word "free5gc" on them. As I took a deeper look, I noted that:
- 23 (7.6%) were related to Kubernetes;
- 27 (9.0%) were related to docker but not to Kubernetes;
- 35 (11.6%) were written in Shell Script;
- Additional forms of automation (e.g. For AWS environments) were found too
However the focus of my scripts were to (semi-)automatically deploy free5GC, and I couldn't find any projects that would fit this purpose.
Entering into the spirit of FSFE's (FSF Europe) campaign "Public Money? Public Code!" and given that my research is currently being funded by public administration entities (namely CAPES and RNP) I decided to share my code with the community as it may help others in the future.
The scripts were tested within an environment that possessed the following characteristics:
- Bash shell 5.0.17 (or later)
- Ubuntu Server 20.04.6
- Linux Kernel 5.4.x (tested on 5.4.0-189-generic)
- 20GB HDD
- 2GB RAM
- 1x i5 processor CPU core
- 40GB HDD
- 4GB RAM
- 2x i5 processor CPU core

Download the scripts (stable version)
curl -LO https://github.com/oliveiraleo/free5gc-auto-deploy/raw/v1.2.1/install-go.sh
curl -LO https://github.com/oliveiraleo/free5gc-auto-deploy/raw/v1.2.1/deploy-free5gc.sh
chmod +x deploy-free5gc.sh install-go.sh # gives execution permission
Tip: Swap main
with the desired version to use other curl commands in this README
Note: Check the releases page for newer versions or use the latest stable
Download the scripts (nightly version)
curl -LO https://github.com/oliveiraleo/free5gc-auto-deploy/raw/main/install-go.sh
curl -LO https://github.com/oliveiraleo/free5gc-auto-deploy/raw/main/deploy-free5gc.sh
chmod +x deploy-free5gc.sh install-go.sh # gives execution permission
Tip: Use -LOSs
instead of -LO
to suppress curl's output messages (for more information see this page)
Install Go and reload the environment vars
./install-go.sh && source ~/.bashrc
Then install free5gc
./deploy-free5gc.sh
Note: Unless otherwise specified, the script will automatically install the stable version defined by the FREE5GC_VERSION variable, without making any changes to the N3IWF configuration
Currently, deploy-free5gc.sh
script accepts three parameters:
-nightly
: Clones free5GC nightly version set by FREE5GC_NIGHTLY_COMMIT variable instead of the stable one-n3iwf
: Prepares N3IWF's configuration file during the installation-n3iwf-nightly
: Prepares N3IWF's configuration file and installs its nightly version-reset-firewall
: Removes all the rules from iptables and reconfigure them during the installation
Example usage:
./deploy-free5gc.sh -nightly -n3iwf
Download the script
curl -LO https://github.com/oliveiraleo/free5gc-auto-deploy/raw/main/deploy-UERANSIM.sh
chmod +x deploy-UERANSIM.sh # gives execution permission
Then install UERANSIM
./deploy-UERANSIM.sh -stable
Currently, deploy-UERANSIM.sh
script accepts four parameters:
-stable
: Clones UERANSIM stable version-nightly33
: Clones UERANSIM nightly version compatible with free5GC v3.3.0 or below-nightly
: Clones UERANSIM nightly version compatible with free5GC v3.4.0 or above-keep-hostname
: Disables changing the machine hostname during the deploy
Example usage:
./deploy-UERANSIM.sh -nightly
Note: This script requires a "version related" parameter to work. Please select one from the list provided above that is compatible with your environment
Please, follow the instructions from this page
To deploy the gNB:
cd ~/UERANSIM
build/nr-gnb -c config/free5gc-gnb.yaml
To deploy the UE:
cd ~/UERANSIM
sudo build/nr-ue -c config/free5gc-ue.yaml # for multiple-UEs, use -n and -t for number and delay
Download the scripts
curl -LO https://github.com/oliveiraleo/free5gc-auto-deploy/raw/main/install-go.sh
curl -LO https://github.com/oliveiraleo/free5gc-auto-deploy/raw/main/deploy-n3iwue.sh
chmod +x deploy-n3iwue.sh install-go.sh # gives execution permission
Install Go and reload the environment vars
./install-go.sh && source ~/.bashrc
Then install N3IWUE
./deploy-n3iwue.sh
Currently, deploy-n3iwue.sh
script accepts two parameters:
-stable
: Clones N3IWUE stable version-stable341
: Clones N3IWUE stable version compatible with free5GC v3.4.1-nightly
: Clones N3IWUE nightly version-keep-hostname
: Disables changing the machine hostname during the deploy
Example usage:
./deploy-n3iwue.sh -keep-hostname -stable
Please, follow the instructions from this page
To deploy the N3IWUE:
cd ~/n3iwue
./run.sh
On a new machine, download the script
curl -LO https://github.com/oliveiraleo/free5gc-auto-deploy/raw/main/deploy-both-UEs.sh
Then execute it using an interactive shell
bash -i deploy-both-UEs.sh
Note: By default shells invoked by a script are non-interactive, running this script in a non-interactive shell will cause bash environment reload to fail after Go installation. For more information see this page
