Deploy Charmed Magma Access Gateway

Requirements

Management machine

Ubuntu machine with internet access

Access Gateway machine

The Access Gateway must be installed on a machine with the following specifications:

Operating System: Ubuntu 20.04 LTS with Linux Kernel 5.4
Processor: x86-64 dual-core processor (around 2GHz clock speed or faster)
Memory: 4GB RAM
Storage: 32GB or greater SSD
Networking: At least two ethernet interfaces using two different subnets (SGi for internet connectivity and S1 for enodeB connectivity)

!!! danger

Installing this charm will affect the target computer's networking configuration. Make sure it is installed on designated hardware (personal computers are strongly discouraged).

!!! info

Some clouds like AWS use newer kernel versions by default. If you want to downgrade your kernel, please refer to the following [guide](https://discourse.ubuntu.com/t/how-to-downgrade-the-kernel-on-ubuntu-20-04-to-the-5-4-lts-version/26459).

Set up your management environment

Install Juju 2.9 on your management machine
Create and bootstrap a manual cloud
Add the Ubuntu machine to your manual cloud

Install Magma Access Gateway

=== "Option 1: DHCP network configuration"

Deploy Magma Access Gateway:
``` bash
juju deploy magma-access-gateway-operator --config sgi=enp0s1 --config s1=enp0s2 --channel=edge --to <AGW machine ID>
```

!!! info
    The interface names will need to be adjusted based on your specific machine.

=== "Option 2: Static network configuration"

Create a file called `agw_config.yaml` that contains the following content:

``` yaml
---
magma-access-gateway-operator:
  sgi: enp0s1
  sgi-ipv4-address: 192.168.0.2/24
  sgi-ipv4-gateway: 192.168.0.1
  sgi-ipv6-address: fd7d:3797:378b:a502::2/64
  sgi-ipv6-gateway: fd7d:3797:378b:a502::1
  s1: enp0s2
  s1-ipv4-address: 192.168.1.2/24
  s1-ipv6-address: fd7d:3797:378b:a503::2/64
  dns: '["8.8.8.8", "208.67.222.222"]'
```

!!! info
    The interface names and IP addresses will need to be adjusted based on your specific machine.

Deploy Magma Access Gateway:

```bash
juju deploy magma-access-gateway-operator --config agw_config.yaml --channel=edge --to <AGW machine ID>
```
