Deploy ROSA cluster

1. Install AWS CLI, rosa CLI and jq.
2. Set AWS access key secrets
   • as environment variables
   • or in .env
3. Get a token for Red Hat's cloud console from https://console.redhat.com/openshift/token/rosa/ and
   • login with rosa login --token="ey..."
   • or set in .env
4. Create the cluster:
   • for a ROSA/Classic cluster run ./deploy-classic.sh <cluster_name> <aws_region>, e.g. ./deploy-classic.sh rosa1 us-east-1
   • for a ROSA/HCP cluster run ./deploy-hcp.sh <cluster_name> <aws_region>, e.g. ./deploy-hcp.sh rosa2 eu-central-1

Be sure to note the cluster-admin password printed at the end.

  rosa list instances-types
  
  aws ec2 describe-instance-type-offerings --location-type availability-zone \
     --filters "Name=location,Values=${aws_az}" --region ${aws_region} --output text

• Deploy VPC and subnets using Terraform:

  echo "INFO: deploying VPC using Terraform"
  ${this_dir}/deploy-vpc-tf.sh
  pushd ${this_dir}/tf
  export SUBNET_IDS=$(terraform output -raw cluster-subnets-string)
  popd
