Setup for Amazon EKS Clusters

On Amazon AWS, Krossboard is available as ready-to-use virtual machine images. This release approach makes its deployment as simple than creating an EC2 virtual machine.

Once deployed, the Krossboard instance is able to automatically discover and handle your EKS clusters. By default, the discovery works on a per AWS region basis, meaning that the instance does automatically discover and handle all your EKS clusters belonging to the region in which it’s deployed.

This guide shows how to setup Krossboard for a given AWS region. It’ll take you a couple of minutes to make it up and running.

Before you begin

This installation guide assumes that:

  • You have subscribed to a Krossboard offer that includes the use of cloud images.
  • You have a basic level of practice with AWS concepts.
  • You have an active AWS account with administrator access to create and configure your Krossboard instance. Krossboard itself needs read-only access to your EKS clusters.
  • You have access to a bash >=4 terminal.
  • You have kubectl, curl and jq installed and accessible from your terminal.

Deploy a Krossboard instance

The commands below shall deploy an instance of Krossboard in a couple of minutes.

Beforehand review the following parameters and adapt them if applicable.

  • Set the variable KB_AWS_REGION with the region of your EKS clusters (default is eu-central-1). This must be a region where Krossboard is currently available.
  • Set the variable KB_AWS_KEY_PAIR with a valid key pair in EC2. If you want to create a new key pair, read this documentation.
  • Set the variable KB_AWS_INSTANCE_TYPE with the instance type (default is t2.small).
export KB_AWS_KEY_PAIR='MyKeyPair'
export KB_AWS_REGION='eu-central-1'
export KB_AWS_INSTANCE_TYPE='t2.small'
curl -so \ && \
    bash ./

On success a summary of the installation shall be displayed as below:

=== Summary the Krossboard instance ===
Instance Name => krossboard-2020-08-27-1598480511
Instance ID => i-02ba079c0decfcff9
Region => eu-central-1
Key Pair => krossboard-test

Handle New EKS clusters

During the installation, the Krossboard deployment script discovers and takes over existing EKS clusters (in the same region). After the installation, you need apply the following change to enable RBAC access (read-only) to each new EKS cluster.

curl -so
bash ./ $KB_ROLE_ARN

Replace ARN_OF_KROSSBOARD_ROLE with the ARN of the role bound to your instance of Krossboard, and YOUR_TARGET_REGION with your target AWS region.

Get access to Krossboard UI

Open a browser tab and point it to the Krossboard URL displayed at the end of the installation script.

It may take a few seconds before the instance finishes its initialization, during this time you may experience a loading error in the browser.

Here are the default username and password to sign in:

  • Username: krossboard
  • Password (default): Kr0sSB8qrdAdm

It’s highly recommended to change this default password as soon as possible.

sudo /opt/krossboard/bin/krossboard-change-passwd
