+# Argo Workflows with ingress domain name
+
+Example on how to deploy Amazon EKS with addons configured via ArgoCD.
+In this example the ArgoCD is configured with ingress using a https domain name managed on Route53
+
+
+**Create DNS Hosted Zone in Route 53:**
+
+In this step you will delegate your registered domain DNS to Amazon Route53. You can either delegate the top level domain or a subdomain.
+```shell
+export TF_VAR_domain_name=<my-registered-domain> # For example: example.com or subdomain.example.com
+```
+
+You can use the Console, or the `aws` cli to create a hosted zone. Execute the following command only once:
+```sh
+aws route53 create-hosted-zone --name $TF_VAR_domain_name --caller-reference "$(date)"
+```
+Use the NameServers in the DelegatoinSet to update your registered domain NS records at the registrar.
+
+
+After creating the Route53 zone deploy the EKS Cluster
+```shell
+terraform init
+terraform apply
+```
+
+Access Terraform output to configure `kubectl` and `argocd`
+```shell
+terraform output
+```
+
+To access ArgoCD thru ingress https use the following command to get URL and passwords
+```shell
+echo "URL: https://$(kubectl get ing -n argocd argo-cd-argocd-server -o jsonpath='{.spec.tls[0].hosts[0]}')"
+echo "Username: admin"
+echo "Password: $(kubectl get secrets argocd-initial-admin-secret -n argocd --template="{{index .data.password | base64decode}}")"
+```
+
+Destroy EKS Cluster
+```shell
+./destroy.sh
+```
