Hosted Control Planes for ROSA HCP

HyperShift

Set environment variables

CLUSTER_NAME="rosa-hcp-rcs"
PREFIX_NAME="hcp-rcs"
REGION="us-east-1"
VERSION="4.14.9"
USER=rcarrata

Retrieve the AWS Installer Role ARN

USER_ARN=$(aws iam get-user --user-name $USER --query 'User.Arn' --output text)

Create Networking Infrastructure for HCP

mkdir hypershift-tf
cd hypershift-tf
curl -s -o setup-vpc.tf https://raw.githubusercontent.com/openshift-cs/OpenShift-Troubleshooting-Templates/master/rosa-hcp-terraform/setup-vpc.tf

terraform init
terraform plan -out rosa.plan -var aws_region=$REGION -var cluster_name=$CLUSTER_NAME
terraform apply rosa.plan

Grab the Networking Infrastructure subnets

PRIVATE_SUBNET=`terraform output -raw cluster-private-subnet`
PUBLIC_SUBNET=`terraform output -raw cluster-public-subnet`
echo $PRIVATE_SUBNET
echo $PUBLIC_SUBNET

Create Account Roles

rosa create account-roles --force-policy-creation --mode auto --prefix $PREFIX_NAME

Build Installer, Support and Worker roles to be used afterwards

INSTALLER_ROLE=$(echo $USER_ARN | sed "s/user\/$USER/role\/$PREFIX_NAME-HCP-ROSA-Installer-Role/")
echo $INSTALLER_ROLE
SUPPORT_ROLE=$(echo $USER_ARN | sed "s/user\/$USER/role\/$PREFIX_NAME-HCP-ROSA-Support-Role/")
echo $SUPPORT_ROLE
WORKER_ROLE=$(echo $USER_ARN | sed "s/user\/$USER/role\/$PREFIX_NAME-HCP-ROSA-Worker-Role/")
echo $WORKER_ROLE

Configure STS OIDC

rosa create oidc-config --mode=auto -y

Set environment variable for cluster-name

OIDC_ID=$(rosa list oidc-config -o json | jq -r '[.[] | select(.last_used_timestamp == null)] | sort_by(.creation_timestamp) | last | .id')
echo $OIDC_ID

Create the required IAM operator roles

rosa create operator-roles --prefix $PREFIX_NAME --oidc-config-id $OIDC_ID --hosted-cp --installer-role-arn $INSTALLER_ROLE --mode auto

Provision Cluster

rosa create cluster --hosted-cp --sts --cluster-name $CLUSTER_NAME  --subnet-ids $PUBLIC_SUBNET,$PRIVATE_SUBNET --mode auto  --region $REGION --oidc-config-id $OIDC_ID --version $VERSION --operator-roles-prefix $PREFIX_NAME -y

Watch Provisioning Logs

rosa logs install -c $CLUSTER_NAME --region $REGION --watch

Generate a Cluster Admin user

rosa create admin -c $CLUSTER_NAME

Obtain the API_URL

API_URL=$(rosa describe cluster -c $CLUSTER_NAME -o json | jq -r '.api.url')
echo $API_URL

Obtain the Console URL

CONSOLE_URL=$(oc get route -n openshift-console console -o jsonpath='{.spec.host}')
echo $CONSOLE_URL
