[Cloud9 EC2 생성]

• t3.small로 Cloud9 시작
• EC2 IAM권한부여(Admin) , Public IP 부여
• AWS 관리형 임시 자격 증명 비활성화

# 기존 임시 자격증명 제거 
aws sts get-caller-identity --query Arn 
# Cloud9 EC2가 사용하고있는 IAM Role 확인

EC2 IAM권한부여(Admin)확인

unzip awscliv2.zip
sudo ./aws/install
export PATH=/usr/local/bin:$PATH
source ~/.bash_profile
aws --version
# 2 버전 확인

[Kubectl 설치]

sudo chmod +x /usr/local/bin/kubectl
kubectl version --client=true --short=true
# kubectl설치 확인

[기타 툴 설치]

# jq 설치
sudo yum install -y bash-completion
# kubectl명령어 자동완성
curl -O https://bootstrap.pypa.io/get-pip.py

#pip update (CodeCommit시 필요)

[eksctl설치]

curl --silent --location "https://github.com/weaveworks/eksctl/releases/latest/download/eksctl_$(uname -s)_amd64.tar.gz" | tar xz -C /tmp
sudo mv -v /tmp/eksctl /usr/local/bin
eksctl version

[Cloud9 추가 셋팅]

export AWS_REGION=$(curl -s 169.254.169.254/latest/dynamic/instance-identity/document | jq -r '.region')
# AWS 인스턴스 메타데이터 
echo "export AWS_REGION=${AWS_REGION}" | tee -a ~/.bash_profile
aws configure set default.region ${AWS_REGION}
aws configure get default.region
# 리전설정 확인 (ap-northeast-2a)

export ACCOUNT_ID=$(curl -s 169.254.169.254/latest/dynamic/instance-identity/document | jq -r '.accountId')
