**Prerequisites**
| Server | CPU | RAM | DISK | IP | OS |
|:-------:|:-----:|:----:|:-----:|:--------------:|:------------:|
| Master | 2 CPU | 4 GB | 20 GB | 192.168.22.160 | Ubuntu 22.04 |
| Worker1 | 4 CPU | 6 GB | 40 GB | 192.168.22.161 | Ubuntu 22.04 |

Resources can be used through the **bootstrap-cluster folder**, there are 2 ways, namely **script files** and **ansible playbooks**, we recommend using **ansible playbooks** for ease of configuration
**1. Setup Environment**
-
For setup, running all of this step on **master node** and step 1-9, 15 installing openvswitch on **worker node**.
1. Clone the repository
```bash
git clone https://github.com/sandyxd18/k8s-5g-manifest.git
cd k8s-5g-manifest/
```
2. Install ansible
```bash
sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository --yes --update ppa:ansible/ansible
sudo apt install ansible
```
3. Setup Ansible control node
```bash
ansible-galaxy collection install -r requirements.yaml
sudo apt install python3-pip
pip3 install kubernetes
```
4. Write IP and ansible user on inventory
```bash
nano bootstrap-cluster/ansible/inventory/kube_node
```
```ini
[master]
10.x.x.x ansible_user=**
[worker]
10.x.x.x ansible_user=**
10.x.x.x ansible_user=**
```
5. Run Ansible-Playbook for install dependencies
```bash
ansible-playbook bootstrap-cluster/ansible/playbook/kube_dependencies.yaml -i bootstrap-cluster/ansible/inventory/kube_node
```
If you want to run only some task, you can use tags such as, basic, swap, kernel-modules, sysctl, containerd, and kubernetes. Example:
```bash
ansible-playbook bootstrap-cluster/ansible/playbook/kube_dependencies.yaml -i bootstrap-cluster/ansible/inventory/kube_node --tags "containerd"
```
```bash
ansible-playbook bootstrap-cluster/ansible/playbook/kube_dependencies.yaml -i bootstrap-cluster/ansible/inventory/kube_node --tags "basic,containerd"
```
This file run on all nodes, if you want to run only on your prefer node, you can run like this:
```
ansible-playbook bootstrap-cluster/ansible/playbook/kube_dependencies.yaml -i bootstrap-cluster/ansible/inventory/kube_node --limit master
```
6. Run Ansible-Playbook for create a cluster
```bash
ansible-playbook bootstrap-cluster/ansible/playbook/kube_cluster.yaml -i bootstrap-cluster/ansible/inventory/kube_node
```
7. Run Ansible-Playbook for joining worker to the cluster
```bash
ansible-playbook bootstrap-cluster/ansible/playbook/kube_join.yaml -i bootstrap-cluster/ansible/inventory/kube_node
```
8. Run Ansible-Playbook for install OVS on each node
```bash
ansible-playbook bootstrap-cluster/ansible/playbook/kube_ovs_install.yaml -i bootstrap-cluster/ansible/inventory/kube_node
```
9. Run Ansible-Playbook for install some needed dependencies on master node
```bash
ansible-playbook bootstrap-cluster/ansible/playbook/kube_master.yaml -i bootstrap-cluster/ansible/inventory/kube_node
```
**2. Deploy 5G Component**
-
For deploying 5G component, run some command only on master node as a controller on kubernetes cluster.
1. Run inside repo directory
```bash
cd k8s-5g-manifest/
```
2. Create Open5gs namespace
```bash
kubectl create namespace open5gs
```
3. Deploy mongodb for Open5gs on Open5gs namespace
```bash
kubectl apply -k mongodb -n open5gs
```
4. Add NAD Multus for secondary NIC on POD
```bash
kubectl apply -k networking -n open5gs
```
5. Deploy Open5gs
```bash
kubectl apply -k 5gc -n open5gs
```
6. Deploy WebUI for Adding some subscriber data
```bash
kubectl apply -k webui -n open5gs
```
7. Add admin user for WebUI on MongoDB Container
```bash
kubectl exec -it mongodb-0 -n open5gs -- mongo
```
```
use open5gs
