========================================

Pre-Requirements

Create a Route53 DNS Zone

https://console.aws.amazon.com/route53/ DIG ns k8s.claudioteixeira.com

## Install CLI Software

Kops 1.9

brew update && brew install kops kops version

Kubectl

Kops needs a place to store it's configs. Create a s3 bucket aws s3 mb s3://kops-cluster1.k8s.claudioteixeira.com aws s3 ls

## Store kops config storage on a variable export KOPS_STATE_STORE=s3://kops-cluster1.k8s.claudioteixeira.com

Create and start cluster (via EC2, 2 workers)

kops create cluster \
--cloud=aws --zones=eu-west-1b \
--dns-zone=k8s.claudioteixeira.com \
--name=kops-cluster1.k8s.claudioteixeira.com --yes

kops validate cluster

What Kops has done?

  • Created VPC

  • Created IAM Roles
  • Created Volumes
  • Created Security Groups
  • Created Subnets
  • Created EC2 instances (defaults 1 Master, 2 Workers)
