[20210820] AWS CloudShellで EKS の作業環境を整える

[linzhengen]

概要

EKS WorkShop通りでやると、自然にcloud9を使うことになるが、EKSクラスタ作成後にCloudShellを使ったほうが良さそうです。

手順

• aws-auth configmapのmapRolesにroleを追加

  mapRoles: |
  ...
  - rolearn: hoge-role-name # `aws sts get-caller-identity | jq .Arn`の値を設定
    username: hoge-user-name
    groups:
      - system:masters # k8s default group, root permission

• 各種ツールのインストールとkubeconfig設定

  mkdir -p $HOME/.local/bin
  cd $HOME/.local/bin
  curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.21.2/bin/linux/amd64/kubectl
  chmod +x kubectl 
  curl --silent --location "https://github.com/weaveworks/eksctl/releases/latest/download/eksctl_$(uname -s)_amd64.tar.gz" | tar xz -C /tmp
  sudo mv /tmp/eksctl $HOME/.local/bin
  export VERIFY_CHECKSUM=false
  curl https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3 | bash
  sudo mv /usr/local/bin/helm $HOME/.local/bin
  echo "sudo yum install -y bash-completion > /dev/null 2>&1" >> ~/.bash_profile
  kubectl completion bash >  $HOME/.bash_completion
  echo "complete -F __start_kubectl k" >> $HOME/.bash_completion
  echo "alias k=kubectl" >> ~/.bashrc
  aws eks update-kubeconfig --name eks-cluster-name
