How to create a AWS kubernetes cluster easy and quickly

1. Download and Install kops:

# curl -LO https://github.com/kubernetes/kops/releases/download/$(curl -s https://api.github.com/repos/kubernetes/kops/releases/latest | grep tag_name | cut -d '"' -f 4)/kops-linux-amd64

# chmod +x kops-linux-amd64

# mv kops-linux-amd64 /usr/local/bin/kops

# kops version

Version 1.15.0 (git-9992b4055)

2. Install AWS cli:

# pip3 install awscli --upgrade --user

# aws --version

aws-cli/1.14.28 Python/2.7.5 Linux/3.10.0-1062.9.1.el7.x86_64 botocore/1.8.35

3. Configure AWS cli to work with your AWS account:

# aws configure

        We need configure:

• AWS Acces Key ID

• AWS Secret Access Key
• Default region and
• Default output format: is "blank" and ENTER.

4. Create a bucket in your AWS for the cluster configurations:

# aws s3api create-bucket --bucket <name new bucket> --region <AWS region> --create-bucket-configuration LocationConstraint=<AWS region>

For example:

# aws s3api create-bucket --bucket mycluster-k8s-demo --region us-west-2 --create-bucket-configuration LocationConstraint=us-west-2

5. Set the KOPS_STATE_STORE environment variable:

# export KOPS_STATE_STORE=s3://mycluster-k8s-demo

6. Create a kubernetes cluster with kops:

# kops create cluster mycluster-k8s-demo.k8s.local --zones us-west2 --yes

Wait something minutes...

7. Validate your kubernetes cluster:

# kops validate cluster

8. List nodes:

# kubectl get nodes --show-labels

At this point, your k8s cluster is ready for jobs.

• To connect to master node, check your EC2 instances public URL (In your AWS Console - EC2 instances) and connect with ssh using:

# ssh .i ~/.ssh/id_rsa admin@<your public address to master node>

For example:

# ssh -i ~/.ssh/id_rsa admin@ec2-54-244-170-110.us-west-2.compute.amazonaws.com

• To End, AWS charges! If you are not going to use the cluster, delete it, if you don't do it then pay what you consume, AWS Law.

# kops delete cluster <full name cluster>

For example:

# kops delete cluster mycluster-k8s-demo.k8s.local

Remember check your AWS Console to ensure the deleted of resources or close or delete your AWS account for more security.
