# Kubernetes/OpenShift etcd

To create a new application for Kubernetes/OpenShift etcd database backup, go to the tab: **Applications -> Instances**

Then select the **Create** button. The Creating an Application Definition section will be displayed, which needs to be completed.

This is a description of how your script is going to be invoked - you need to specify:

* **Name** - unique name of the application in the Storware Backup & Recovery system
* **Choose Node Config** - select which node should perform the task
* **Backup policy** - specify which backup policy should be used for this application
* **Command execution configuration** - select a prepared template for Kubernetes/OpenShift etcd backup or create a [new](https://docs.storware.eu/administration/applications/execution-configurations) one yourself

On the SSH access subtab, complete the following fields:

* **Host** - set the address of the host where the Kubernetes/OpenShift node exists
* **Port** - set the host port

Next, select OS Credentials or create a new one and provide the following information:

* **Name** - unique name of the OS Credentials
* **User** - indicate a user for connecting to the ssh
* **Password** - enter the connection password
* **SSH key path** - alternatively you can specify the ssh key path for authorization

After **saving** the changes to the application, you need to configure the **environment variables** in the **settings section** of your application as needed.

When using the built-in script for database backup, define:

* **VP\_ETCD\_CLIENT\_KEY** - client key path
* **VP\_ETCD\_CERT** - client cert path
* **VP\_ETCD\_CA\_CERT** - CA cert path
* **VP\_ETCD\_ADDRESS** - address of etcd instance
* **ETCDCTL\_API** - version of etcdctl api

Make sure you have etcdctl tool installed in node you are connecting to. You can find installation instructions on this [page](https://etcd.io/docs/v3.4/install/)
{% endhint %}

**Note:** After the new application is fully configured, **save** the changes and go to the [Backup SLAs](https://docs.storware.eu/administration/applications/backup-slas) configuration.
