+
+## Requirements
+
+* Terraform 1.3.7
+
+## Quickstart
+
+### Export Variables
+
+* Your NIFCLOUD credentials:
+
+  ```bash
+  export NIFCLOUD_ACCESS_KEY_ID=<YOUR ACCESS KEY>
+  export NIFCLOUD_SECRET_ACCESS_KEY=<YOUR SECRET ACCESS KEY>
+  ```
+
+* The SSH KEY used to connect to the instance:
+  * FYI: [Cloud Help(SSH Key)](https://pfs.nifcloud.com/help/ssh.htm)
+
+  ```bash
+  export TF_VAR_SSHKEY_NAME=<YOUR SSHKEY NAME>
+  ```
+
+* The IP address to connect to bastion server:
+
+  ```bash
+  export TF_VAR_working_instance_ip=$(curl ifconfig.me)
+  ```
+
+### Create The Infrastructure
+
+* Run terraform:
+
+  ```bash
+  terraform init
+  terraform apply -var-file ./sample-inventory/cluster.tfvars
+  ```
+
+### Setup The Kubernetes
+
+* Generate cluster configuration file:
+
+  ```bash
+  ./generate-inventory.sh > sample-inventory/inventory.ini
+  ```
+
+* Export Variables:
+
+  ```bash
+  BASTION_IP=$(terraform output -json | jq -r '.kubernetes_cluster.value.bastion_info | to_entries[].value.public_ip')
+  API_LB_IP=$(terraform output -json | jq -r '.kubernetes_cluster.value.control_plane_lb')
+  CP01_IP=$(terraform output -json | jq -r '.kubernetes_cluster.value.control_plane_info | to_entries[0].value.private_ip')
+  export ANSIBLE_SSH_ARGS="-o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o ProxyCommand=\"ssh root@${BASTION_IP} -W %h:%p\""
+  ```
+
+* Set ssh-agent"
+
+  ```bash
+  eval `ssh-agent`
+  ssh-add <THE PATH TO YOUR SSH KEY>
+  ```
+
+* Run cluster.yml playbook:
+
+  ```bash
+  cd ./../../../
+  ansible-playbook -i contrib/terraform/nifcloud/inventory/inventory.ini cluster.yml
+  ```
+
+### Connecting to Kubernetes
+
+* [Install kubectl](https://kubernetes.io/docs/tasks/tools/) on the localhost
+* Fetching kubeconfig file:
+
+  ```bash
+  mkdir -p ~/.kube
+  scp -o ProxyCommand="ssh root@${BASTION_IP} -W %h:%p" root@${CP01_IP}:/etc/kubernetes/admin.conf ~/.kube/config
+  ```
+
+* Rewrite /etc/hosts
+
+  ```bash
+  sudo echo "${API_LB_IP} lb-apiserver.kubernetes.local" >> /etc/hosts
+  ```
+
+* Run kubectl
+
+  ```bash
+  kubectl get node
+  ```
+
+## Variables
+
+* `region`: Region where to run the cluster
+* `az`: Availability zone where to run the cluster
+* `private_ip_bn`: Private ip address of bastion server
+* `private_network_cidr`:  Subnet of private network
+* `instances_cp`: Machine to provision as Control Plane. Key of this object will be used as part of the machine' name
+  * `private_ip`: private ip address of machine
+* `instances_wk`: Machine to provision as Worker Node. Key of this object will be used as part of the machine' name
+  * `private_ip`: private ip address of machine
+* `instance_key_name`: The key name of the Key Pair to use for the instance
+* `instance_type_bn`: The instance type of bastion server
+* `instance_type_wk`: The instance type of worker node
+* `instance_type_cp`: The instance type of control plane
+* `image_name`: OS image used for the instance
+* `working_instance_ip`: The IP address to connect to bastion server
+* `accounting_type`: Accounting type. (1: monthly, 2: pay per use)

 For more information on kubeconfig and accessing a Kubernetes cluster, refer to
 the Kubernetes [documentation](https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/).

+## Accessing Kubernetes Dashboard
+
+Supported version is kubernetes-dashboard v2.0.x :
+
+- Login option : token/kubeconfig by default
+- Deployed by default in "kube-system" namespace, can be overridden with `dashboard_namespace: kubernetes-dashboard` in inventory,
+- Only serves over https
+
+Access is described in [dashboard docs](https://github.com/kubernetes/dashboard/tree/master/docs/user/accessing-dashboard). With kubespray's default deployment in kube-system namespace, instead of kubernetes-dashboard :
+
+- Proxy URL is <http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#/login>
+- kubectl commands must be run with "-n kube-system"
+
+Accessing through Ingress is highly recommended. For proxy access, please note that proxy must listen to [localhost](https://github.com/kubernetes/dashboard/issues/692#issuecomment-220492484) (`proxy  --address="x.x.x.x"` will not work)
+
+For token authentication, guide to create Service Account is provided in [dashboard sample user](https://github.com/kubernetes/dashboard/blob/master/docs/user/access-control/creating-sample-user.md) doc. Still take care of default namespace.
+
+Access can also by achieved via ssh tunnel on a control plane :
+
+```bash
+# localhost:8081 will be sent to control-plane-1's own localhost:8081
+ssh -L8001:localhost:8001 user@control-plane-1
+sudo -i
+kubectl proxy
+```
+

+## Prerequisite Generic Deployment Command
+
+!!! attention
+    The default configuration watches Ingress object from *all the namespaces*.
+    To change this behavior use the flag `--watch-namespace` to limit the scope to a particular namespace.
+
+!!! warning
+    If multiple Ingresses define different paths for the same host, the ingress controller will merge the definitions.
+
+!!! attention
+    If you're using GKE you need to initialize your user as a cluster-admin with the following command:
+
+```console
+kubectl create clusterrolebinding cluster-admin-binding \
+--clusterrole cluster-admin \
+--user $(gcloud config get-value account)
+```
+
+The following **Mandatory Command** is required for all deployments except for AWS. See below for the AWS version.
+
+```console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.13.3/deploy/static/provider/cloud/deploy.yaml
+```
+
+### Provider Specific Steps
+
+There are cloud provider specific yaml files.
+
+#### Docker for Mac
+
+Kubernetes is available in Docker for Mac (from [version 18.06.0-ce](https://docs.docker.com/docker-for-mac/release-notes/#stable-releases-of-2018))
+
+First you need to [enable kubernetes](https://docs.docker.com/docker-for-mac/#kubernetes).
+
+Then you have to create a service:
+
+```console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/cloud-generic.yaml
+```
+
+#### minikube
+
+For standard usage:
+
+```console
+minikube addons enable ingress
+```
+
+For development:
+
+1. Disable the ingress addon:
+
+```console
+minikube addons disable ingress
+```
+
+1. Execute `make dev-env`
+1. Confirm the `nginx-ingress-controller` deployment exists:
+
+```console
+$ kubectl get pods -n ingress-nginx
+NAME                                       READY     STATUS    RESTARTS   AGE
+default-http-backend-66b447d9cf-rrlf9      1/1       Running   0          12s
+nginx-ingress-controller-fdcdcd6dd-vvpgs   1/1       Running   0          11s
+```
+
+#### AWS
+
+In AWS we use an Elastic Load Balancer (ELB) to expose the NGINX Ingress controller behind a Service of `Type=LoadBalancer`.
+Since Kubernetes v1.9.0 it is possible to use a classic load balancer (ELB) or network load balancer (NLB)
+Please check the [elastic load balancing AWS details page](https://aws.amazon.com/elasticloadbalancing/details/)
+
+##### Elastic Load Balancer - ELB
+
+This setup requires to choose in which layer (L4 or L7) we want to configure the Load Balancer:
+
+- [Layer 4](https://en.wikipedia.org/wiki/OSI_model#Layer_4:_Transport_Layer): Use an Network Load Balancer (NLB) with TCP as the listener protocol for ports 80 and 443.
+- [Layer 7](https://en.wikipedia.org/wiki/OSI_model#Layer_7:_Application_Layer): Use an Elastic Load Balancer (ELB) with HTTP as the listener protocol for port 80 and terminate TLS in the ELB
+
+For L4:
+
+```console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/aws/deploy.yaml
+```
+
+For L7:
+
+Change the value of `service.beta.kubernetes.io/aws-load-balancer-ssl-cert` in the file `provider/aws/deploy-tls-termination.yaml` replacing the dummy id with a valid one. The dummy value is `"arn:aws:acm:us-west-2:XXXXXXXX:certificate/XXXXXX-XXXXXXX-XXXXXXX-XXXXXXXX"`
+
+Check that no change is necessary with regards to the ELB idle timeout. In some scenarios, users may want to modify the ELB idle timeout, so please check the [ELB Idle Timeouts section](#elb-idle-timeouts) for additional information. If a change is required, users will need to update the value of `service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout` in `provider/aws/deploy-tls-termination.yaml`
+
+Then execute:
+
+```console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/aws/deploy-tls-termination.yaml
+```
+
+This example creates an ELB with just two listeners, one in port 80 and another in port 443
+
+![Listeners](https://github.com/kubernetes/ingress-nginx/blob/main/docs/images/elb-l7-listener.png)
+
+##### ELB Idle Timeouts
+
+In some scenarios users will need to modify the value of the ELB idle timeout.
+Users need to ensure the idle timeout is less than the [keepalive_timeout](http://nginx.org/en/docs/http/ngx_http_core_module.html#keepalive_timeout) that is configured for NGINX.
+By default NGINX `keepalive_timeout` is set to `75s`.
+
+The default ELB idle timeout will work for most scenarios, unless the NGINX [keepalive_timeout](http://nginx.org/en/docs/http/ngx_http_core_module.html#keepalive_timeout) has been modified,
+in which case `service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout` will need to be modified to ensure it is less than the `keepalive_timeout` the user has configured.
+
+*Please Note: An idle timeout of `3600s` is recommended when using WebSockets.*
+
+More information with regards to idle timeouts for your Load Balancer can be found in the [official AWS documentation](https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/config-idle-timeout.html).
+
+##### Network Load Balancer (NLB)
+
+This type of load balancer is supported since v1.10.0 as an ALPHA feature.
+
+```console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/aws/service-nlb.yaml
+```
+
+#### GCE-GKE
+
+```console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/cloud-generic.yaml
+```
+
+**Important Note:** proxy protocol is not supported in GCE/GKE
+
+#### Azure
+
+```console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/provider/cloud-generic.yaml
+```
+
+#### Bare-metal
+
+Using [NodePort](https://kubernetes.io/docs/concepts/services-networking/service/#type-nodeport):
+
+```console
+kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/baremetal/deploy.yaml
+```
+
+!!! tip
+    For extended notes regarding deployments on bare-metal, see [Bare-metal considerations](https://github.com/kubernetes/ingress-nginx/blob/main/docs/deploy/baremetal.md).
+
+### Verify installation
+
+To check if the ingress controller pods have started, run the following command:
+
+```console
+kubectl get pods --all-namespaces -l app.kubernetes.io/name=ingress-nginx --watch
+```
+
+Once the operator pods are running, you can cancel the above command by typing `Ctrl+C`.
+Now, you are ready to create your first ingress.
+
+### Detect installed version
+
+To detect which version of the ingress controller is running, exec into the pod and run `nginx-ingress-controller version` command.
+
+```console
+POD_NAMESPACE=ingress-nginx
+POD_NAME=$(kubectl get pods -n $POD_NAMESPACE -l app.kubernetes.io/component=controller -o jsonpath='{.items[0].metadata.name}')
+
+kubectl exec -it $POD_NAME -n $POD_NAMESPACE -- /nginx-ingress-controller --version
+```
+
+## Using Helm
+
+NGINX Ingress controller can be installed via [Helm](https://helm.sh/) using the chart [ingress-nginx/ingress-nginx](https://kubernetes.github.io/ingress-nginx).
+Official documentation is [here](https://kubernetes.github.io/ingress-nginx/deploy/#using-helm)
+
+To install the chart with the release name `my-nginx`:
+
+```console
+helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
+helm install my-nginx ingress-nginx/ingress-nginx
+```
+
+Detect installed version:
+
+```console
+POD_NAME=$(kubectl get pods -l app.kubernetes.io/name=ingress-nginx -o jsonpath='{.items[0].metadata.name}')
+kubectl exec -it $POD_NAME -- /nginx-ingress-controller --version
+```
