Install Docker-based Access Gateway on Ubuntu

Prerequisites

To set up a Magma Access Gateway, you will need a machine that satisfies the following requirements:

  • AGW_HOST: aarch64 or 64bit-X86 machine. You will need two ethernet ports. In this guide, enp1s0 and enp2s0 are used:
    • enp1s0: Will carry any traffic that is not S1. That is, data plane traffic (SGi), control plane traffic (Orc8r HTTP2) and management (ssh).
    • enp2s0: S1 interface.

NOTE:

  • Interface names might have different names on your hardware, so just replace enp1s0 and enp2s0 with your current interface names when following this guide.

  • The agw_install_docker.sh script will rename the enp1s0 interface to eth0.

  • If you do not want all internet traffic to go through enp1s0 to separate control plane (Orc8r Http2 traffic) from user plane, you may want to add another interface and configure proper routing.

Deployment

1. Create boot USB stick and install Ubuntu on your AGW host

  • Download the Ubuntu Server 20.04 LTS .iso image from the Ubuntu website
  • Create a bootable USB using this Etcher tutorial
  • Boot your AGW host from USB
    • Press F11 to select boot sequence. WARNING: This might be different for your machine.
    • If you see two options to boot from USB, select the non-UEFI option.
  • Install and configure your Access Gateway according to your network defaults.
    • Make sure to enable ssh server and utilities (untick every other).
  • Connect your SGi interface to the internet and select this port during the installation process to get an IP using DHCP.

2. Deploy magma on the AGW_HOST

Do pre-installation steps

Become root user:

sudo -i

Copy your rootCA.pem file from orc8r to the following location:

mkdir -p /var/opt/magma/certs
vim /var/opt/magma/certs/rootCA.pem

Run AGW installation

Download AGW docker install script

wget https://github.com/magma/magma/raw/v1.8/lte/gateway/deploy/agw_install_docker.sh
bash agw_install_docker.sh

Configure AGW

Once you see the output Reboot this machine to apply kernel settings, reboot your AGW host.

Create control_proxy.yml file with your orc8r details:

cat << EOF | sudo tee /var/opt/magma/configs/control_proxy.yml
cloud_address: controller.orc8r.magmacore.link
cloud_port: 443
bootstrap_address: bootstrapper-controller.orc8r.magmacore.link
bootstrap_port: 443
fluentd_address: fluentd.orc8r.magmacore.link
fluentd_port: 24224

rootca_cert: /var/opt/magma/certs/rootCA.pem
EOF

Start your access gateway:

cd /var/opt/magma/docker
sudo docker compose --compatibility up -d

Now get Hardware ID and Challenge key and add AGW in your orc8r:

docker exec magmad show_gateway_info.py

Then restart your access gateway:

sudo docker compose --compatibility up -d --force-recreate
