In this blog post, I will demonstrate how to install kubernetes on aws cloud using kops tool.

Step-1 Create hosted zone

  • Create aws free tier account
  • Login to aws web console
  •  Services > Route53 -> DNS Management -> Create hosted zone
  • copy the nameservers

Step-2 Get a domain/subdomain

  • Create domain on freenom.com
  • Add the AWS nameservers
  • Create s3 bucket

Step-3 IAM

  • on aws web console > services > IAM
  • users > add user
  • Access type > check the following
    – programmatic access
    – aws management console access
  •  next
  •  Create group > group-name: admin (select adminstrator access)
  • next > create user
  • download csv (credentials.csv)

 

Step-4 Install & configure aws

  • installing aws: http://docs.aws.amazon.com/cli/latest/userguide/installing.html
  • aws configure & provide from the credentials.csv
  • region can be of your choice

Example:


~ $cat credentials.csv

User name,Password,Access key ID,Secret access key,Console login link
test-user,5f9EAAAAH*ZG,AKIAJAAAAM4RKQZBWNQ,dAcPTlq6dAAAAAAAy5+H53PCM4F,https://AAAAAAA.signin.aws.amazon.com/console

~ $aws configure

AWS Access Key ID [****************BWNQ]: AKIAJAAAAM4RKQZBWNQ
AWS Secret Access Key [****************CM4F]: dAcPTlq6dAAAAAAAy5+H53PCM4F
Default region name [us-west-2]:
Default output format [None]:

Step-5 Install kops

Step-6 Create cluster & Update

Create

syntax:


kops create cluster --name=<domain name> --state=<s3-url> --zones=<aws-zone> --node-count=2 --node-size=t2.micro --master-size=t2.micro --dns-zone=<domain name>

in my case:


kops create cluster --name=kops.cf --state=s3://kops-state-s3 --zones=ap-south-1a --node-count=2 --node-size=t2.micro --master-size=t2.micro --dns-zone=kops.cf

Update:

syntax:

kops update cluster <domain-name> –state=<s3-url> –yes

in my case:

kops update cluster kops.cf --state=s3://kops-state-s3 --yes

If you want to delete the cluster anytime you can use the following command,


kops delete cluster --name=kops.cf --state=s3://kops-state-s3 --yes

Step-7 Install kubectl

Step-8 Wait & Verify

  •  Wait for DNS A records to appear

 


~ $kubectl get nodes
NAME STATUS AGE VERSION

ip-172-20-50-104.ap-south-1.compute.internal Ready,master 39m v1.6.2
