Using the Kognitio Launcher¶
Kognitio on AWS and the Kognitio Launcher are available from Version 8.2.3 onwards.
This page describes how to use the Kognitio Launcher to create and manage Kognitio on AWS servers (also referred to as clusters where there may be multiple nodes clustered together to form a server).
Before you begin you will need:
a Kognitio Launcher CloudFormation stack and the launcher password entered when creating the stack. This is accessible from the AWS Management Console
Open the Launcher¶
Open the Kognitio Launcher CloudFormation Stack then use the PublicURL or PrivateURL from the output tab and log into your Kognitio Launcher by entering the default “admin” user and the launcher password.
The launcher interface has two parts, the sidebar and the main page. The sidebar has menus at the top and servers will appear below when they are launched. The main page is to the right and occupies most of the window. It’s content varies according to the operation that’s being performed.
Clicking on a cluster in the sidebar will display the cluster management page for that cluster. This allows you to monitor, manage and terminate a cluster. If you have more clusters than will fit in the sidebar they can be accessed using the Manage->Clusters menu.
The Kognitio Launcher Welcome page is the first page you will see when the Launcher is opened and you can get to it using the Start Here link in the sidebar. It presents you with a number of option buttons which are explained below.
This button takes you to a page with the following options:
Launch a new Cluster - launches one or more EC2 instances and creates a Kognitio server cluster on them.
Assemble a cluster - is an advanced option that allows you to assemble a set of EC2 instances you have already launched using the Kognitio AMI. The instances must all be inside the same AWS availability zone and VPC subnet. This option provides extra control over resource allocation but is more complicated.
These options are also available from the Create Server link in the sidebar.
This button will open a new tab in your web browser with the Getting Started With Kognitio page open.
