TVK QuickStart Plugin
This page describes how to install and use the TVK Quick-Start Plugin.

Introduction

The tvk-quickstart kubectl plugin is used primarily to get users up and running quickly. It is tested with OCP, RKE, GKE, and DO Kubernetes clusters.

What Does the Plugin Achieve?

  • Preflight check: Performs prerequisite checks for all TVK requirements.
  • TVK Installation: Installs TVK, TVM (UI), and free trial license.
  • TVK Management Console Configuration: Configures control access to the UI. Users can choose either Loadbalancer, Nodeport, or PortForwarding.
  • Target Creation: Creates and validates the target storage for storing backup images. Users can create an S3 (DigitalOCean Spaces / AWS S3) or an NFS-based target.
  • Run Backup and Restore of Sample Applications: Run sample tests for a label, namespace, operator, and helm-based applications. By default, backups and restores are performed against:
    • Label-based MySQL Database application
    • Namespace-based WordPress application
    • Operator-based MySQL Database
    • Helm-based MongoDB based application

Modes of Operation

There are two modes to use the tvk-quickstart plugin:
  1. 1.
    Interactive
  2. 2.
    Non-interactive

Interactive

  1. 1.
    For interactive installation of TVK operator and manager, configure the TVK UI, create a target and run a sample backup restore, using the command: kubectl tvk-quickstart [options]
  2. 2.
    During interactive execution, the user is prompted for input for various options that enable the plugin to perform installation and deployment operations. Use the information provided in the following table to guide you in these options:
Parameter
Description
-i, --install_tvk
Installs TVK and its free trial license. TVK will be installed as upstream operator. A cluster scope TVM custom resource triliovault-manager is also created.
-c, --configure_ui
Configures the TVK UI. This option will only work if the cluster has TVM application installed.
-t, --target
Creates target for backup and restore jobs.
-s, --sample_test
Creates sample backup and restore jobs.
-p, --preflight
Checks if all the TVK pre-requisites are satisfied
A user may specify more than one option with each tvk-quickstart execution. For example, to install, configure, create a target and run samples quickly, execute the following single command:_ kubectl tvk-quickstart -i -c -t -s

Non-interactive

In non-interactive mode, tvk-quickstart performs all operations; preflight checks, installation, UI configuration, and runs sample backup and restore tests. However, all the user input is provided in a configuration file. Use the following steps to invoke tvk-quickstart in the non-interactive mode:
  1. 1.
    Create an input_config file, using the sample input_config file as a template. The non-interactive mode leverages values in the input_config file.
  2. 2.
    Edit any variables in the configuration file. Each variable description and the possible values of the variable is described in the following table.
  3. 3.
    Run the following command to execute the plugin in a non-interactive method: kubectl tvk-quickstart -n
  4. 4.
    The user is now prompted to provide the path of the input_config file.

Parameters For input_config

input-config Parameter
Description
PREFLIGHT
This parameter checks whether or not preflight should be executed. It accepts one of the following values: [True, False]. More info around this can be found here
proceed_even_PREFLIGHT_fail
This option is dependent of PREFLIGHT execution. If the user wishes to proceed despite checks failing in preflight execution, this variable must be set to y/Y. This variable accepts one of the following values [Y,y,n,N].
