# multicluster-gateway-controller
## Description:
The multi-cluster gateway controller, leverages the gateway API standard and Open Cluster Management to provide multi-cluster connectivity and global load balancing
Key Features:
- Central Gateway Definition that can then be distributed to multiple clusters
- Automatic TLS and cert distribution for HTTPS based listeners
- DNSPolicy to decide how North-South based traffic should be balanced and reach the gateways
- Health checks to detect and take remedial action against unhealthy endpoints
- Cloud DNS provider integrations (AWS route 53) with new ones being added (google DNS)
When deploying the multicluster gateway controller using the make targets, the following will be created:
* Kind cluster(s)
* Gateway API CRDs in the control plane cluster
* Ingress controller
* Cert manager
* LetsEncrypt certs
## Prerequisites:
* AWS or GCP
* Various dependencies installed into $(pwd)/bin e.g. kind, yq etc.
* Run `make dependencies`
* openssl>=3
* On macOS a later version is available with `brew install openssl`. You'll need to update your PATH as macOS provides an older version via libressl as well
* On Fedora use `dnf install openssl`
* go >= 1.21
### 1. Running the controller in the cluster:
1. Set up your DNS Provider by following these [steps](https://github.com/Kuadrant/dns-operator/blob/main/docs/provider.md)
1. Setup your local environment
```sh
make local-setup MGC_WORKLOAD_CLUSTERS_COUNT=
```
1. Build the controller image and load it into the control plane
```sh
kubectl config use-context kind-mgc-control-plane
make kind-load-gateway-controller
```
1. Deploy the controller(s) to the control plane cluster
```sh
make deploy-gateway-controller
```
1. (Optional) View the logs of the deployed controller
```sh
kubectl logs -f $(kubectl get pods -n multi-cluster-gateways | grep "mgc-" | awk '{print $1}') -n multi-cluster-gateways
```
## 2. Running the controller locally:
1. Set up your DNS Provider by following these [steps](https://github.com/Kuadrant/dns-operator/blob/main/docs/provider.md)
1. Setup your local environment
```sh
make local-setup MGC_WORKLOAD_CLUSTERS_COUNT=
```
1. Run the controller locally:
```sh
kubectl config use-context kind-mgc-control-plane
make build-gateway-controller run-gateway-controller
```
## 3. Clean up local environment
In any terminal window target control plane cluster by:
```bash
kubectl config use-context kind-mgc-control-plane
```
If you want to wipe everything clean consider using:
```bash
make local-cleanup # Remove kind clusters created locally and cleanup any generated local files.
```
If the intention is to cleanup kind cluster and prepare them for re-installation consider using:
```bash
make local-cleanup-mgc MGC_WORKLOAD_CLUSTERS_COUNT= # prepares clusters for make local-setup-mgc
```
