  • Install AWS CLI using brew install aws
  • Create an AWS Account if you are first time user.
  • Run the below command to install kops on your macOS:
brew update && brew install kops

Adding Access & Secret Key

aws configure

This will store your credential under ~/.aws/credentials

bucket_name=collabstore

Create a AWS Bucket

[Captains-Bay]🚩 >  baws s3api create-bucket --bucket ${bucket_name} --region us-east-1
{
    "Location": "/collabstore"
}

Configure

aws s3api put-bucket-versioning --bucket ${bucket_name} --versioning-configuration Status=Enabled

Configure DNS Name

 aws route53 create-hosted-zone --name collabnix.com --caller-reference 2
 

export KOPS_CLUSTER_NAME=ajeet.k8s.local

Export Cluster Name

export KOPS_CLUSTER_NAME=ajeet.k8s.local

Exporting Kops State Store

[Captains-Bay]🚩 >  export KOPS_STATE_STORE=s3://${bucket_name}

[Captains-Bay]🚩 >  kops create cluster \
> --node-count=2 \
> --node-size=t2.medium \
> --zones=us-east-1a \
> --name=${KOPS_CLUSTER_NAME}
...

Must specify --yes to apply changes

Cluster configuration has been created.

Suggestions:
 * list clusters with: kops get cluster
 * edit this cluster with: kops edit cluster k8.aws.dev.collabnix.com
 * edit your node instance group: kops edit ig --name=ajeet.k8s.local nodes
 * edit your master instance group: kops edit ig --name=ajeet.k8s.local master-us-east-1a

Finally configure your cluster with: kops update cluster ajeet.k8s.local --yes
