# k8s-freepbx
Run FreePBX (Asterisk) on Kubernetes.
Just pure open source power.
## Requirements
- FQDN
- Ability to create type A DNS record for the public IP address allocated by the cloud provider
This PoC is based on Vultr Kubernetes Engine
## Database deployment
Freepbx requires MySql or MariaDb
A statefulset of 3 replicas (adjust replicas number according to your needs) with one pod for WRITE operations and the others for READ ops.
1. Create Namespace and ConfigMap
```bash
kubectl apply -f mysql/namespace.yaml
kubectl apply -f mysql/configmap.yaml
```
2. Create services
```bash
kubectl apply -f mysql/services.yaml
```
3. Deploy
```bash
kubectl apply -f mysql/statefulset.yaml
```
4. Test connection with READ operation
```
kubectl run mysql-client --image=mysql:5.7 -i -t --rm --restart=Never -- mysql -h mysql-read -e "SHOW DATABASES;"
```
or
```
kubectl run mysql-client-loop --image=mysql:5.7 -i -t --rm --restart=Never --\
bash -ic "while sleep 1; do mysql -h mysql-read -e 'SELECT @@server_id,NOW()'; done"
```
## Freebpx deployment
1.
```
```
## Exposing services
1. Deploy nginx-controller (read cloud provider docs to check features, in most cases a public IP address will be automatically allocated to it)
### TLS (optional but recommended)
This step uses HTTP-01 challenge with Letsencrypt as `ClusterIssuer`.
1. Install cert-manager for managing TLS certificates
```bash
kubectl apply -f cert-manager/install-v1.12.0.yaml
```
2. Deploy Letsencrypt, before applying, change `email` field within the yaml
```bash
kubectl apply -f letsencrypt/clusterissuer.yaml
```
### KUARD test (optional)
1. Expose and deploy KUARD to test networking functionality (keep order)
```bash
kubectl apply -f kuard/service.yaml
kubectl apply -f kuard/deployment.yaml
```
2. Check if web server within the pod is running
```bash
# PLAIN HTTP
kubectl run curl-client --image=curlimages/curl:8.1.0 -i -t --rm --restart=Never -- http://:8080
```
3. Expose services by creating `Ingress`. Before applying, change `hosts` and `host` field in ingress-tls.yaml if you want TLS or `host` field in ingress.yaml (no TLS), by inserting your FQDN
```bash
# NO TLS
kubectl apply -f kuard/ingress.yaml
# WITH TLS
kubectl apply -f kuard/ingress-tls.yaml
```
4. Check from outside
```bash
Open http://YOURFQDN or https://YOURFQDN
```
