Installing Rancher Prime PAYG on AWS

This page covers installing the Rancher Prime PAYG offering on Amazon's AWS Marketplace.

Preparing your cluster​

OIDC provider​

Your EKS cluster requires that you install an OIDC provider. To check that you've installed an OIDC provider, find the OIDC issuer with the following command. Substitute <cluster-name> with the name of your EKS cluster and <region> with the region where it is running:

aws eks describe-cluster --name <cluster-name> --region <region> --query cluster.identity.oidc.issuer --output text

This should return a URL, such as https://oidc.eks.region.amazonaws.com/id/1234567890ABCDEF. The part after https:// (e.g. oidc.eks.region.amazonaws.com/id/1234567890ABCDEF) is the OIDC Provider Identity. The final section of the URL, 1234567890ABCDEF, is the OIDC ID.

Use the OIDC ID to check if the EKS cluster has a provider:

aws iam list-open-id-connect-providers | grep <oidc-id>

If the last command produces no output, create an OIDC provider:

eksctl utils associate-iam-oidc-provider --cluster <cluster-name> --region <region> --approve

IAM Role​

You must create an IAM role and an attached policy to provide the necessary permissions. The role name is passed as an argument during the Helm deployment.

Create the role with a <role-name> of your choosing (for example, rancher-csp-iam-role) and attach the required policy:

eksctl create iamserviceaccount \
  --name rancher-csp-billing-adapter \
  --namespace cattle-csp-billing-adapter-system \
  --cluster <cluster-name> \
  --region <region> \
  --role-name <role-name> --role-only \
  --attach-policy-arn 'arn:aws:iam::aws:policy/AWSMarketplaceMeteringFullAccess' \
  --approve

Installing Rancher​

  1. Log Helm into the AWS Marketplace Elastic Container Registry (ECR) to fetch the application. The AWS Marketplace ECR is always in the us-east-1 region:

    export HELM_EXPERIMENTAL_OCI=1

    aws --region us-east-1 ecr get-login-password \
      | helm registry login --username AWS \
      --password-stdin 709825985650.dkr.ecr.us-east-1.amazonaws.com

  2. Install Rancher with Helm. Customize your Helm installation values if needed.

    note

    Rancher Prime uses cert-manager to issue and maintain its certificates. Rancher generates its own CA certificate and signs certificates with that CA.

    The Rancher hostname must be resolvable by a public DNS. For more details, see Prerequisites. For example, if the DNS name is rancher.my.org, then replace <host-name> with rancher.my.org when running the helm install command.

    helm install -n cattle-rancher-csp-deployer-system rancher-cloud --create-namespace \
    oci://709825985650.dkr.ecr.us-east-1.amazonaws.com/suse/$REPOSITORY/rancher-cloud-helm/rancher-cloud \
      --version <chart-version> \
      --set rancherHostname=<host-name>\
      --set rancherServerURL=https://<host-name>\
      --set rancherReplicas=<replicas> \
      --set rancherBootstrapPassword=<bootstrap-password>\
      --set rancherIngressClassName=nginx \
      --set global.aws.accountNumber=<aws-account-id>\
      --set global.aws.roleName=<role-name>
    note

    Monitor the logs for the rancher-cloud pod since it is deleted one minute after a successful or failed installation.

    kubectl logs -f rancher-cloud -n cattle-rancher-csp-deployer-system

  3. After a successful deployment, the following command should produce similar output:

    kubectl get deployments --all-namespaces

Response:

Check Helm Chart Installation​

  1. Check that the Helm chart installation completed:
helm ls -n cattle-rancher-csp-deployer-system
  1. Verify the status of the installation:
helm status rancher-cloud -n cattle-rancher-csp-deployer-system

Refer to the Troubleshooting section if installation fails.

When Helm chart installation successfully completes, Rancher Prime will be installed.

Log into the Rancher Dashboard​

You may now log in to the Rancher dashboard by pointing your browser to the Rancher server URL, https://<host-name>. The <host-name> is the hostname you entered when you installed Rancher.

note

The Rancher hostname must be resolvable by public DNS. For more details, see Prerequisites.

Uninstalling Rancher Prime PAYG Offering​

Run the following command to uninstall Rancher Prime:

helm uninstall -n cattle-rancher-csp-deployer-system rancher-cloud

Uninstalling Rancher Prime may not remove all of the Kubernetes resources created by Rancher. Run the Rancher resource cleanup script to perform a more comprehensive cleanup.

The best practice for uninstalling the Rancher Prime PAYG offering is to migrate any non-Rancher workloads to a different cluster and destroy the Rancher cluster.

danger

Ensure that you prepare and migrate any non-Rancher workloads off of the cluster before you destroy the cluster. These resources are nonrecoverable.
