# MetalLB Test
## Software Requirements
- Minikube v1.33.1 or newer
- OrbStack v1.6.2 or newer
Note: This tutorial was updated on macOS 14.5. The below steps doesn't work with Docker Desktop v4.31.1 because it doesn't expose Linux VM IP addresses to the host OS (i.e. macOS).
## Steps To Reproduce
1. create Minikube cluster
```zsh
minikube start -p metallb-test
```
2. install MetalLB
```zsh
kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.14.5/config/manifests/metallb-native.yaml
```
3. clone github repository
```zsh
git clone https://github.com/conradwt/metallb-test.git
```
4. change directory
```zsh
cd metallb-test
```
5. locate the subnet
```zsh
docker network inspect metallb-test | jq '.[0].IPAM.Config[0]["Subnet"]'
```
Note: This grabs the Subnet value from the first config block and it should
look something like the following:
```json
{
...
"Config": [
{
"Subnet": "194.1.2.0/24",
"Gateway": "194.1.2.1"
}
]
...
}
```
Then one can use an IP address range like the following:
```
194.1.2.100-194.1.2.110
```
6. update the `metallb-address-pool.yaml`
```yaml
apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:
name: demo-pool
namespace: metallb-system
spec:
addresses:
- 194.1.2.100-194.1.2.110
```
7. apply the address pool manifest
```zsh
kubectl apply -f metallb-address-pool.yaml
```
8. apply Layer 2 advertisement manifest
```zsh
kubectl apply -f metallb-advertise.yaml
```
9. apply deployment manifest
```zsh
kubectl apply -f nginx-deployment.yaml
```
10. apply service manifest
```zsh
kubectl apply -f nginx-service-loadbalancer.yaml
```
11. check that your service has an IP address
```zsh
kubectl get svc nginx-service
```
example output
```text
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
nginx-service LoadBalancer 10.106.207.172 194.1.2.100 80:32000/TCP 17h
```
12. expected output
input:
```zsh
curl 194.1.2.100
```
output:
```text
Welcome to nginx!
html { color-scheme: light dark; }
body { width: 35em; margin: 0 auto;

13. actual output
input:
```zsh
curl 194.1.2.100
```
output:
```text
