<p>I am trying to setup Kubernetes cluster on AWS
I have hosted zone created by Route53 Registrar</p>

<pre><code>When i try
kops create cluster --zones "eu-central-1a","eu-central-1b" --master-count 3 --master-size=t2.micro --node-count 2 --node-size=t2.micro --name=marinche.markovic-q9.com.
</code></pre>

<p>markovic-q9.com. is my Hosted Zone</p>

<p>Although I edited my bash_profile</p>

<pre><code>export KOPS_CLUSTER_NAME=marinche
export KOPS_STATE_STORE=s3://kops-state-3107b
</code></pre>

<p>I got serious issues</p>

<pre><code>Name: Invalid value: "marinche.markovic-q9.com.": Cluster Name must be a valid DNS name (e.g. --name=mycluster.myzone.com) errors: a DNS-1123 subdomain must consist of lower case alphanumeric characters..
</code></pre>

<p>Why?</p>

Richard Rublev
<p>You have a trailing dot in the domain name, this leads to the assumption that markovic-q9 is already a third level domain. The setup allows only lower case alphanummeric characters in the subdomain.</p>
