But Terrafrom script ask the question 'Are you sure you want to continue connecting (yes/no)' and i am not able to pass the answer 'yes' to it.

Public_subnets = local.public_subnet_cidr You can use bastion hosts to create SSH connections to compute instances that dont have public IP.

Security group access between bastion host and worker nodes in the Amazon EKS cluster. kubectl is installed on the bastion host and has access to the EKS cluster. It's entirely possible this is fully a networking problem and not an EKS/Terraform problem as my understanding of how the VPC and its security groups fit into this picture is not entirely mature. A bastion host that can be used for troubleshooting and is accessible from your workstation.I am able to SSH into the bastion via my static IP (that's the var.company_vpn_ips in the code).The Bastion configuration works in the sense that the user data runs successfully and installs kubectl and the kubeconfig file.Previously when I had cluster_endpoint_public_access set to false the terraform apply command would not even complete as it could not access the /healthz endpoint on the cluster. I have (for the time being) switched the cluster to a public cluster for testing purposes.Here are the facts/things I know to be true: The problems that I am encountering is that after SSH-ing into the bastion, I cannot ping the cluster and any commands like kubectl get pods timeout after about 60 seconds. To accomplish this, I've modified the Terraform EKS example slightly (code at bottom of the question). SSH users are managed by their public key, simply drop the SSH key of the user in the /public-keys path of the bucket. All SSH commands are logged on an S3 bucket for security compliance, in the /logs path. Resources (deployments, cron jobs, etc) configurable via the Terraform Kubernetes module Features This module will create an SSH bastion to securely connect in SSH to your private instances.I am working on a Terraform project that has an end goal of an EKS cluster with the following properties: ![]()
