How to install a Kubernetes cluster

How to create the infrastructure in AWS

On Cloud9:

aws configure

git clone https://github.com/academiaonline/kubernetes --single-branch -b main

# CHOOSE THE CONFIGURATION FOR YOUR CLUSTER DEPENDING ON THE REGION AND PROTOCOL
# https://github.com/academiaonline/kubernetes/tree/main/etc/aws
cluster=mumbai-kubelet-3masters-3workers-https

# CHOOSE YOUR OPERATING SYSTEM
os=rhel8
os=ubuntu18

# CHOOSE YOUR CONTAINER ENGINE
engine=containerd
engine=cri-o
engine=docker

location=kubernetes/${os}/${engine}/etc/aws/${cluster}.yaml

aws cloudformation create-stack --stack-name ${os}-${engine}-${cluster}-$( date +%s ) --template-body file://${location} --capabilities CAPABILITY_NAMED_IAM --parameters ParameterKey=RecordSetName,ParameterValue=kubernetes-${os}-${engine}

How to install a Kubernetes cluster with 3 masters and any number of workers

On the leader (master1):

# CHOOSE YOUR OPERATING SYSTEM
os=rhel8
os=ubuntu18

# CHOOSE YOUR CONTAINER ENGINE
engine=containerd
engine=cri-o
engine=docker

git clone https://github.com/academiaonline/kubernetes --single-branch -b main
source kubernetes/${os}/${engine}/bin/install-leader.sh

On the master2 and master3:

# CHOOSE YOUR OPERATING SYSTEM
os=rhel8
os=ubuntu18

# CHOOSE YOUR CONTAINER ENGINE
engine=containerd
engine=cri-o
engine=docker

git clone https://github.com/academiaonline/kubernetes --single-branch -b main

# EXPORT THE FOLLOWING VARIABLES FROM THE OUTPUT OF THE LEADER
export ip_leader=xxx
export token_certificate=xxx
export token_discovery=xxx
export token_token=xxx
export kube=kube-xxx

source kubernetes/${os}/${engine}/bin/install-master.sh

On the workers:

# CHOOSE YOUR OPERATING SYSTEM
os=rhel8
os=ubuntu18

# CHOOSE YOUR CONTAINER ENGINE
engine=containerd
engine=cri-o
engine=docker

git clone https://github.com/academiaonline/kubernetes --single-branch -b main

# EXPORT THE FOLLOWING VARIABLES FROM THE OUTPUT OF THE LEADER
export token_discovery=xxx
export token_token=xxx
export kube=kube-xxx
export ip_master1=xxx

# EXPORT THE FOLLOWING VARIABLES FROM THE OUTPUT OF THE MASTERS
export ip_master2=xxx
export ip_master3=xxx

source kubernetes/${os}/${engine}/bin/install-worker.sh
