Two EKS clusters in `eu-west-1` and `us-east-1`.

Terraform code for cluster reference setup can be found [here](https://github.com/AbsaOSS/k8gb/tree/master/docs/examples/route53)

The EKS setup is identical to [Route53 tutorial](../docs/deploy_route53.md)

## Deploy k8gb
Terraform code for cluster reference setup can be found [here](../docs/examples/route53)

Example `values.yaml` override configs can be found [here](https://github.com/AbsaOSS/k8gb/tree/master/docs/examples/ns1/)

You can use `helm` to deploy stable release from Helm repo
## Deploy k8gb

Use `helm` to deploy stable release from Helm repo

```sh
helm repo add k8gb https://www.k8gb.io
```

Alternatively, use make target to deploy right from the git repository
Example `values.yaml` configuration files can be found [here](../docs/examples/ns1/)

In `eu-west-1` cluster execute
```sh
make deploy-gslb-operator VALUES_YAML=./docs/examples/ns1/k8gb-cluster-ns1-eu-west-1.yaml

#switch kubectl context to us-east-1
helm -n k8gb upgrade -i k8gb k8gb/k8gb --create-namespace -f ./docs/examples/ns1/k8gb-cluster-ns1-eu-west-1.yaml
```

make deploy-gslb-operator VALUES_YAML=./docs/examples/ns1/k8gb-cluster-ns1-us-east-1.yaml
In `us-east-1` cluster execute
```sh
helm -n k8gb upgrade -i k8gb k8gb/k8gb --create-namespace -f ./docs/examples/ns1/k8gb-cluster-ns1-us-east-1.yaml
```

Create NS1 secret in each cluster
