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 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

Note: After the new application is fully configured, save the changes and go to the Backup SLAs configuration.
