Automated creation of EKS

Automate the process of Getting Started with Amazon EKS

Dependency

macOS Mojave kubectl AWS CLI

Usage

Start EKS

$ ./eks-start.sh

Deploy Dashboard

$ ./resource/dashboard/deploy.sh

Add iam user

Only the IAM user who created the EKS cluster can use the kubectl command.
To use the kubectlk command by another IAM user, you need to update the configmap.
Change the <ARN of the IAM user you want to add> and <Any name> of the prepare/config/configmap.yml file.

$ source env/env.sh

$ ROLE_ARN=$(aws cloudformation describe-stacks \
    --stack-name $EKS_WORKER_STACK_NAME \
    --query 'Stacks[0].Outputs[0].OutputValue' \
    | sed -E 's/.(.*)./\1/')

$ cat << EOT > prepare/config/configmap.yml
apiVersion: v1
kind: ConfigMap
metadata:
  name: aws-auth
  namespace: kube-system
data:
  mapRoles: |
    - rolearn: $ROLE_ARN
      username: system:node:{{EC2PrivateDNSName}}
      groups:
        - system:bootstrappers
        - system:nodes
  mapUsers: |
    - userarn: <The ARN of the IAM user you want to add>
      username: <Any name>
      groups:
        - system:masters

Deploy prepare/config/configmap.yml file.
