missing kube-apiserver and other pods

[ankur6ue]

I'm trying to create a kubernetes cluster on AWS using:

kops create cluster --zones=us-east-1a --name=dev.k8s.local --state=s3://<bucket_name> --discovery-store=s3://<bucket_name>/${NAME}/discovery --node-size t2.small --master-size t2.small --node-count 1

However the cluster never gets in a healthy state.

Output of kops validate

output of kubectl get pods -n kube-system

Please help.. using kops version 1.31.0

@ankur6ue t2.small is too small for control plane. Use t2.medium instead or some other instance type with 4GB or memory..

Thanks for the reply. I used t2.medium for the control plane, but get the same as before:

any ideas?

try adding --dns=none when creating the cluster.

Exactly the same as before
kops create cluster --zones=us-east-1a --cloud=aws --name=dev.k8s.local --state=s3://ankur-kops-k8s-state-store --discovery-store=s3://ankur-kops-k8s-oidc-store/${NAME}/discovery --node-size t2.medium --master-size t2.small --node-count 1 --dns=none

I verified the AWS resources (EC2 instances, security groups etc) are created as expected. Also ran journalctl -u kops-configuration.service. on the control plane node, and nodeup seems to be succeeding.

Any other ideas? I'm following the instructions on the deploying to AWS page to the letter.. this used to work when I last tried 2 years ago. Using latest version of kops, kubernetes etc.

This is the output of kubectl get pods -n kube-system

In the above, I was still using a small size node as the master node. I corrected that error, but the results are the same:
