Installing DKubeX on EKS Cluster using Terraform

The terraform scripts available in the dkubex-tf GitHub repository can be used to bring up an AWS EKS cluster and install DKubeX.

Prerequisites

  • Terraform needs to be installed in your system. If you do not have Terraform installed in your system, follow the steps in the following link to install Terraform.

    Install Terraform

  • Make sure the latest version of AWS CLI, kubectl and Helm >=v3.5.0 is installed.

    Note

    For more information regarding AWS CLI installation, please visit Install or update the latest version of the AWS CLI. For more information regarding Helm installation, go to Helm installation.

  • Use the following command in the terminal to configure your AWS CLI. When prompted, provide your ‘Access Key’ and ‘Secret Key’ from your AWS account. When asked about ‘Region’, provide the AWS region in which the setup is going to be installed.

    aws configure

  • Run the following command in the terminal to clone the repo:
