fix: removed unused files

# Swagger Codegen Ignore

# Generated by swagger-codegen https://github.com/swagger-api/swagger-codegen

# Use this file to prevent files from being overwritten by the generator.

# The patterns follow closely to .gitignore or .dockerignore.

# As an example, the C# client generator defines ApiClient.cs.

# You can make changes and tell Swagger Codgen to ignore just this file by uncommenting the following line:

#ApiClient.cs

# You can match any string of characters against a directory, file or extension with a single asterisk (*):

#foo/*/qux

# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux

# You can recursively match patterns against a directory, file or extension with a double asterisk (**):

#foo/**/qux

# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux

# You can also negate patterns with an exclamation (!).

# For example, you can ignore all files in a docs folder with the file extension .md:

#docs/*.md

# Then explicitly reverse the ignore rule for a single file:

#!docs/README.md

3.0.34

### Prepare VM

```

apt update

apt install curl git make gcc -y

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3

chmod 700 get_helm.sh

./get_helm.sh

```

### Installing Microk8s

```

snap install microk8s --classic

newgrp microk8s

usermod -a -G microk8s $USER

chown -f -R $USER ~/.kube

su - $USER

microk8s status --wait-ready

```

### Set aliases

```

alias kubectl='microk8s kubectl'

alias k='microk8s kubectl'

alias helm='microk8s helm3'

echo "alias kubectl='microk8s kubectl'" >> ~/.bashrc

echo "alias k='microk8s kubectl'" >> ~/.bashrc

echo "alias helm='microk8s helm3'" >> ~/.bashrc

echo 'complete -F __start_kubectl k' >> ~/.bashrc # autocomplete for k8s

source ~/.bashrc

```

### config calico

```

# /var/snap/microk8s/current/args/cni-network/

microk8s kubectl apply -f /var/snap/microk8s/current/args/cni-network/cni.yaml

sudo snap restart microk8s

microk8s kubectl delete ippools default-ipv4-ippool

microk8s kubectl rollout restart daemonset/calico-node -n kube-system

```

```

microk8s enable dns ingress dashboard storage community helm3

microk8s enable multus

```

### Building gtp5g module

```

mkdir /root/5gc

cd /root/5gc

git clone https://github.com/free5gc/gtp5g.git

cd gtp5g

make

make install

```

### setting up ip forwarding in the node

```

echo "sudo sysctl -w net.ipv4.ip_forward=1" >> ~/.bashrc

echo "iptables -t nat -A POSTROUTING -o enp0s3 -j MASQUERADE" >> ~/.bashrc

echo "systemctl stop ufw" >> ~/.bashrc

echo "iptables -I FORWARD 1 -j ACCEPT" >> ~/.bashrc

source ~/.bashrc

```

### pull free5gc and ueransim repos

```

cd /root/5gc

helm repo add towards5gs 'https://raw.githubusercontent.com/Orange-OpenSource/towards5gs-helm/main/repo/'

helm repo update

helm search repo

helm pull towards5gs/free5gc; helm pull towards5gs/ueransim

tar -zxvf ueransim-2.0.17.tgz

tar -zxvf free5gc-1.1.7.tgz

```

### create the persistent volume for mongodb pod

```

cd /root/ ; mkdir kubedata

cd /root/5gc/

nano pv.yaml

---------

apiVersion: v1

kind: PersistentVolume

metadata:

  name: example-local-pv9

```

### deploy free5gc and ueransim with helm

VM default interface: ```enp0s3```

VM IP: ```10.0.2.15```

VM Gateway: ```10.0.2.2```

VM Subnet: ```10.0.2.0```

```

k create ns 5g

helm -n 5g install free5gc towards5gs/free5gc \

    --set global.n2network.masterIf=enp0s3 \

    --set global.n3network.masterIf=enp0s3 \

    --set global.n4network.masterIf=enp0s3 \

    --set free5gc-upf.upf.n6if.ipAddress=10.0.2.11 \

    --set free5gc-upf.upf.securityContext.privileged=true 

helm -n 5g install  ueransim towards5gs/ueransim \

            --set global.n2network.masterIf=enp0s3 \

            --set global.n3network.masterIf=enp0s3

```

### how to uninstall

```

helm -n 5g uninstall free5gc 

helm -n 5g uninstall ueransim

```

### prepare upf

 - add google dns: ```echo "nameserver 8.8.8.8" >> /etc/resolv.conf```

 - add tcpdup tool:

```

apk update

apk add tcpdump

tcpdump -i any icmp

```

 - enable ip_forwarding in upf

```

echo "1" >  /proc/sys/net/ipv4/ip_forward

cat /proc/sys/net/ipv4/ip_forward

```

 - capture network traffic in pod: ```tcpdump -i any -s 0 -w /test-amf.pcap```
