Terraform and helm charts to provide deployment of the full EKS cluster

Prerequsite

brew update
brew install kubernetes-cli
brew install python3
easy_install pip
pip install awscli — upgrade — user
export PATH=~/.local/bin:$PATH
brew install terraform
brew install terragrunt
brew install direnv
brew install tfenv

Setup .envrc

Setup your KUBECONFIG and aws credentials

export AWS_CONFIG_FILE=
export AWS_SHARED_CREDENTIALS_FILE=
export KUBECONFIG=$(pwd)/eks-vpc/kubeconfig_GOD-EKS

Authorize users to access the cluster

Initially, only the system that deployed the cluster will be able to access the cluster. To authorize other users for accessing the cluster, config needs to be modified by using the steps given below:

• Modify file eks-vpc/locals.tfas:

locals {

  map_users = [
    {
      userarn  = "arn:aws:iam::${data.aws_caller_identity.current.account_id}:user/tgaleev"
      username = "tgaleev"
      groups   = ["system:masters"]
    }
  ]

  map_roles = []

  map_accounts = []
}
