We are going to create a simple cluster with one master node and two worker nodes. To do it using kops, we will need:
- A user profile declared in ~/.aws/credentials (this is done automatically if you authenticate using aws configure).
- An S3 bucket to store kops cluster state. In order to store the representation of our cluster and its state, we need to create a dedicated S3 bucket for kops to use. This bucket will become the source of truth for our cluster configuration.
- DNS configured. This means we will need a Route 53 hosted zone in the same AWS account. Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. Kops will use it to create records needed by the cluster. If you are using newer kops (1.6.2 or later), then DNS configuration is optional. Instead, a gossip-based cluster can be easily created. For the purposes...
