Kops and kubeconfig

• after you installed your cluster with kops you can use the kube config file generated to enter to the cluster from another point
• to manage the cluster from another machine you need:
  • the yaml config file generated by default in ~/.kube/config
  • the name of the cluster and the name of the bucket were kops stored the state of the cluster

bucket_name=bucket-for-kops-2
cluster_name=test.k8s.local

• • se the corresponding environment variables, examples:

export KOPS_CLUSTER_NAME=$cluster_name
export KOPS_STATE_STORE=s3://${bucket_name}

• use the script set-local-kubectl-config.sh to set locally the access to the k8s cluster with kubectl

$ . set-local-kubectl-config.sh
