Kops Create Cluster fails with gossip in AWS Linux

Question

I'm following the tutorial in https://github.com/kubernetes/kops/blob/master/docs/aws.md with a bootstrap EC2 instance with Amazon Linux installed.

And everything seems to be working fine until I need to start configuring the cluster.

This error when running the kops command to create a configuration for the cluster. I couldn`t find any post on how to solve this issue.

Any help?

error assigning default machine type for nodes: error finding default machine type: could not find a suitable supported instance type for the instance group "nodes" (type "Node") in region "us-west-2"

Answer 1

The error is stating you haven't specified an instance type for the EC2 nodes that will act as master and worker nodes.

The following is an example command:

  kops create cluster --name=my-cluster.k8s.local \
  --state=s3://kops-state-1234 --zones=eu-west-1a \
  --node-count=2 --node-size=t2.micro --master-size=t2.micro
