Setup infra & cluster

Setup infra

cd eksa-setup/scripts/aws-tf

terraform init

terraform plan

terraform apply --auto-approve

Note The pem certificate needs to be at ~/.aws/key-pairs/eksa-admin.pem. Else change the script to point to the directory where it is available.

Generate cluster config

export CLUSTER_NAME=mgmt

eksctl anywhere generate clusterconfig $CLUSTER_NAME --provider tinkerbell > eksa-mgmt-cluster.yaml

Create hardware.csv file

# fetch hardware/vm contents from EC2 instance
ssh into EC2 instance: `ssh -i <pem-cert-path> ubuntu@<ec2-instance-ip>`
hardware details should be at: `cat /home/ubuntu/vm-scripts/logs/launch-vms.log`

touch hardware.csv

vi hardware.csv

# populate content as per generated speciifcations in below format
hostname,mac,ip_address,netmask,gateway,nameservers,labels,disk,bmc_ip,bmc_username,bmc_password

Start cluster provisioning

eksctl anywhere create cluster --hardware-csv hardware.csv -f eksa-mgmt-cluster.yaml
