Set up Eks cluster

Step-00: Introduction

• Install AWS CLI

• Install kubectl CLI

• Install eksctl CLI

Step-01: Install AWS CLI

• Reference-1: https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-install.html

• Reference-2: https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2.html

Step-01-01: MAC - Install and configure AWS CLI

• Download the binary and install via command line using below two commands.

# Download Binary
curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"

# Install the binary
sudo installer -pkg ./AWSCLIV2.pkg -target /

• Verify the installation

aws --version
aws-cli/2.0.7 Python/3.7.4 Darwin/19.4.0 botocore/2.0.0dev11

which aws

• Reference: https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-mac.html

Step-01-02: Windows 10 - Install and configure AWS CLI

• The AWS CLI version 2 is supported on Windows XP or later.

• The AWS CLI version 2 supports only 64-bit versions of Windows.

• Download Binary: https://awscli.amazonaws.com/AWSCLIV2.msi

• Install the downloaded binary (standard windows install)

aws --version
aws-cli/2.0.8 Python/3.7.5 Windows/10 botocore/2.0.0dev12

• Reference: https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-windows.html

Step-01-03: Configure AWS Command Line using Security Credentials

• Go to AWS Management Console --> Services --> IAM

• Select the IAM User: kalyan

• Important Note: Use only IAM user to generate Security Credentials. Never ever use Root User. (Highly not recommended)

• Click on Security credentials tab

• Click on Create access key

• Copy Access ID and Secret access key

• Go to command line and provide the required details

aws configure
AWS Access Key ID [None]: ABCDEFGHIAZBERTUCNGG  (Replace your creds when prompted)
AWS Secret Access Key [None]: uMe7fumK1IdDB094q2sGFhM5Bqt3HQRw3IHZzBDTm  (Replace your creds when prompted)
Default region name [None]: us-east-1
Default output format [None]: json

• Test if AWS CLI is working after configuring the above

aws ec2 describe-vpcs

Step-02: Install kubectl CLI

• IMPORTANT NOTE: Kubectl binaries for EKS please prefer to use from Amazon (Amazon EKS-vended kubectl binary)

• This will help us to get the exact Kubectl client version based on our EKS Cluster version. You can use the below documentation link to download the binary.

• Reference: https://docs.aws.amazon.com/eks/latest/userguide/install-kubectl.html

Step-02-01: MAC - Install and configure kubectl

• Kubectl version we are using here is 1.16.8 (It may vary based on Cluster version you are planning use in AWS EKS)

# Download the Package
mkdir kubectlbinary
cd kubectlbinary
curl -o kubectl https://amazon-eks.s3.us-west-2.amazonaws.com/1.16.8/2020-04-16/bin/darwin/amd64/kubectl

# Provide execute permissions
chmod +x ./kubectl

# Set the Path by copying to user Home Directory
mkdir -p $HOME/bin && cp ./kubectl $HOME/bin/kubectl && export PATH=$PATH:$HOME/bin
echo 'export PATH=$PATH:$HOME/bin' >> ~/.bash_profile

# Verify the kubectl version
kubectl version --short --client
Output: Client Version: v1.16.8-eks-e16311

Step-02-02: Windows 10 - Install and configure kubectl

• Install kubectl on Windows 10

mkdir kubectlbinary
cd kubectlbinary
curl -o kubectl.exe https://amazon-eks.s3.us-west-2.amazonaws.com/1.16.8/2020-04-16/bin/windows/amd64/kubectl.exe

• Update the system Path environment variable

C:\Users\KALYAN\Documents\kubectlbinary

• Verify the kubectl client version

kubectl version --short --client
kubectl version --client

Step-03: Install eksctl CLI

Step-03-01: eksctl on Mac

# Install Homebrew on MacOs
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

# Install the Weaveworks Homebrew tap.
brew tap weaveworks/tap

# Install the Weaveworks Homebrew tap.
brew install weaveworks/tap/eksctl

# Verify eksctl version
eksctl version

Step-03-02: eksctl on windows or linux

• For windows and linux OS, you can refer below documentation link.

• Reference: https://docs.aws.amazon.com/eks/latest/userguide/eksctl.html#installing-eksctl
