hypershift-aws-template

Prerequisites

To use this template you must have:

1. Met all the Hypershift prerequisites.

2. Hypershift installed on a Kubernetes/OpenShift cluster. This can be accomplished using one of the following methods:

   • Install Multicluster Engine Operator (MCE) 2.5+ (preferred)
   • Install Hypershift Operator

   If using MCE, create the OIDC provider secret with the S3 bucket from the prior step. E.g.

   kubectl create secret generic hypershift-operator-oidc-provider-s3-credentials \
     --from-file=credentials=$HOME/.aws/credentials \
     --from-literal=bucket=<s3-bucket-name> \
     --from-literal=region=<s3-bucket-region> \
     --namespace local-cluster

3. Created the cluster-provisioner service account and RBAC policies in the current namespace.

   kubectl create -f k8s/cluster-provisioner.yaml

4. Generated a Role ARN for use with the hypershift CLI. E.g.

   hypershift create iam cli-role \
     --aws-creds "$HOME/.aws/credentials" \
     --name "$USER-hypershift-cli-role" \
     --additional-tags="expirationDate=$(date -d '1 year' --iso=minutes --utc)"

5. Created the hypershift secret in the current namespace. E.g.

   kubectl create secret generic hypershift \
     --from-file=aws-credentials=$HOME/.aws/credentials \
     --from-file=pull-secret=<path-to-ocp-pull-secret>

Usage

To create a cluster (and infra/iam):

export VERSION="4.16.11"
export BASE_DOMAIN=<route53-domain>
export ROLE_ARN=<hypershift-cli-role-arn>

helm install \
  --wait \
  --wait-for-jobs \
  --timeout 20m \
  --set "version=$VERSION,baseDomain=$BASE_DOMAIN,hypershiftRoleArn=$ROLE_ARN" \
  "$USER-cluster" \
  ./charts/hypershift-aws-template

To destroy a cluster (and infra/iam):

helm uninstall --timeout 20m "$USER-cluster"
