Cluster access​

Install aws cli​

In order to be able to import he cluster config we need to install the cli

aws cli
msiexec.exe /i https://awscli.amazonaws.com/AWSCLIV2.msi

Then we can login to the aws cli 

# we need the following 
# AWS ACCESS KEY ID 
# AWS ACCESS KEY SECRET
# REGION
# OUTPUT FORMAT: You can choose json 



aws configure

aws sts get-caller-identity

Then we can import the different config details into our .kube/config file 

aws eks --region <region> update-kubeconfig --name <cluster-name>
info

You can rename your contexts for better readabillity by using 

# CHANGE CONTEXT NAME
kubectl config rename-context old-name new-name
info

If you installed kubectx you can now view the your context using 

# LIST CLUSTERS
kubectx

Creating a cluster​

The most efficient way to create a cluster is to use the eksctl tool

And we can use choco to install it

install eksctl
choco install -y eksctl

Now with that installed we can create our cluster. This command will create a new cluster with all the needed node groups.

create cluster
# This can be adapted as needed for more details see the help
# eksctl --help 


eksctl create cluster \
    --name admin \ 
    --region eu-central-1 \
    --version 1.23 \ 
    --nodegroup-name admin \
    --node-type t3.large \
    --nodes 3

Routing​

danger

Unlike other clusters AWS create a public DNS name and not an IP this requires us to handle routing into the cluster slightly different.

Steps

  1. DNS setting: In you dns provider we need to create a cname entry to forward the request coming in to a specific dns name to the AWS dns
  2. Route 53: In Aws Navigate to the Route 53 service and under hosted zones we need to add our domain as a hosted zone. It is enough to define the root dns name
