# Deploy Coder on Azure with an Application Gateway

In certain enterprise environments, the [Azure Application Gateway](https://learn.microsoft.com/en-us/azure/application-gateway/ingress-controller-overview) is required.

These steps serve as a proof-of-concept example so that you can get Coder running with Kubernetes on Azure. Your deployment might require a separate Postgres server or signed certificates.

The Application Gateway supports:

- Websocket traffic (required for workspace connections)
- TLS termination

Refer to Microsoft's documentation on how to [enable application gateway ingress controller add-on for an existing AKS cluster with an existing application gateway](https://learn.microsoft.com/en-us/azure/application-gateway/tutorial-ingress-controller-add-on-existing).
The steps here follow the Microsoft tutorial for a Coder deployment.

## Deploy Coder on Azure with an Application Gateway

1. Create Azure resource group:

```sql
az group create --name myResourceGroup --location eastus
```

1. Create AKS cluster:

```sql
az aks create --name myCluster --resource-group myResourceGroup --network-plugin azure --enable-managed-identity --generate-ssh-keys
```

1. Create public IP:

```sql
az network public-ip create --name myPublicIp --resource-group myResourceGroup --allocation-method Static --sku Standard
```

1. Create VNet and subnet:

```sql
az network vnet create --name myVnet --resource-group myResourceGroup --address-prefix 10.0.0.0/16 --subnet-name mySubnet --subnet-prefix 10.0.0.0/24
```

1. Create Azure application gateway, attach VNet, subnet and public IP:

```sql
az network application-gateway create --name myApplicationGateway --resource-group myResourceGroup --sku Standard_v2 --public-ip-address myPublicIp --vnet-name myVnet --subnet mySubnet --priority 100
```

1. Get app gateway ID:

```sql
appgwId=$(az network application-gateway show --name myApplicationGateway --resource-group myResourceGroup -o tsv --query "id")
```

1. Enable app gateway ingress to AKS cluster:

```sql
az aks enable-addons --name myCluster --resource-group myResourceGroup --addon ingress-appgw --appgw-id $appgwId
```

1. Get AKS node resource group:

```sql
nodeResourceGroup=$(az aks show --name myCluster --resource-group myResourceGroup -o tsv --query "nodeResourceGroup")
```

1. Get AKS VNet name:

```sql
aksVnetName=$(az network vnet list --resource-group $nodeResourceGroup -o tsv --query "[0].name")
```

1. Get AKS VNet ID:

```sql
aksVnetId=$(az network vnet show --name $aksVnetName --resource-group $nodeResourceGroup -o tsv --query "id")
```

1. Peer VNet to AKS VNet:

```sql
az network vnet peering create --name AppGWtoAKSVnetPeering --resource-group myResourceGroup --vnet-name myVnet --remote-vnet $aksVnetId --allow-vnet-access
```

1. Get app gateway VNet ID:

```sql
appGWVnetId=$(az network vnet show --name myVnet --resource-group myResourceGroup -o tsv --query "id")
```

1. Peer AKS VNet to app gateway VNet:

```sql
az network vnet peering create --name AKStoAppGWVnetPeering --resource-group $nodeResourceGroup --vnet-name $aksVnetName --remote-vnet $appGWVnetId --allow-vnet-access
```

1. Get AKS credentials:

```sql
az aks get-credentials --name myCluster --resource-group myResourceGroup
```

1. Create Coder namespace:

```shell
kubectl create ns coder
```

1. Deploy non-production PostgreSQL instance to AKS cluster:

```shell
helm repo add bitnami https://charts.bitnami.com/bitnami
helm install coder-db bitnami/postgresql \
--namespace coder \
--set auth.username=coder \
--set auth.password=coder \
--set auth.database=coder \
--set persistence.size=10Gi
```

1. Create the PostgreSQL secret:

```shell
kubectl create secret generic coder-db-url -n coder --from-literal=url="postgres://coder:coder@coder-db-postgresql.coder.svc.cluster.local:5432/coder?sslmode=disable"
```

1. Deploy Coder to AKS cluster:

```shell
helm repo add coder-v2 https://helm.coder.com/v2
helm install coder coder-v2/coder \
--namespace coder \
--values values.yaml \
--version 2.18.5
```

1. Clean up Azure resources:

```sql
az group delete --name myResourceGroup
az group delete --name MC_myResourceGroup_myCluster_eastus
```

1. Deploy the gateway - this needs clarification

1. After you deploy the gateway, add the following entries to Helm's `values.yaml` file before you deploy Coder:

```yaml
service:
enable: true
type: ClusterIP
sessionAffinity: None
externalTrafficPolicy: Cluster
loadBalancerIP: ""
annotations: {}
httpNodePort: ""
httpsNodePort: ""

ingress:
enable: true
className: "azure-application-gateway"
host: ""
wildcardHost: ""
annotations: {}
tls:
enable: false
secretName: ""
wildcardSecretName: ""
```
