Custom Blueprint

Customers can create and manage "Custom Cluster Blueprints" by adding "addons" to the default cluster blueprints. It is important to emphasize that this "builds on" and "extends" the "Default Cluster Blueprints" and does not replace it.


You can manage the lifecycle of custom blueprints using the Web Console, or RCTL CLI or REST APIs. It is strongly recommended to automate this by integrating RCTL with your existing CI system-based automation pipeline.


Other than the default cluster blueprints, which is common across all projects, all custom blueprints are scoped to a Project. This isolation boundary guarantees that there is no accidental spillover or leakage. If required, blueprints can be shared with selected or all projects.


Custom blueprints can inherit from a default blueprint or golden blueprint.

Default Blueprint

The Default Blueprints available out of the box are the following:

  • default-aks (specific to AKS)
  • default-gke (specific to GKE)
  • default
  • default-openshift (specific to OpenShift)
  • default-upstream (specific to upstream)
  • minimal.

The default blueprint carries core services such as Prometheus, log aggregation and more needed to run enterprise Kubernetes workloads while the minimal blueprint contains the bare-bones necessary components to get a cluster up and running and is better for either dev/test situations, or if you want to completely use your own custom services and add-ons.

Each Default Blueprint has different group of system add-ons with multiple versions. Users can pick any of these Default Blueprint and customize to create a new Blueprint version

Golden Blueprint

A custom blueprint can also inherit from a golden blueprint. This is extremely useful when an admin wants to set a specific set of rules that need to be enforced across a fleet of clusters i.e. a golden path but then for certain cluster types or a smaller group of clusters, needs to potentially enable other services, add more policies, etc. This is also useful to enforce compliance and security as configurations in a golden blueprint cannot be overridden or deleted by the custom blueprint.


Any installation profile, service, and policies specified in a golden blueprint cannot be overridden or deleted in the custom blueprint.

For more information on Golden Blueprints, refer here.


Users manage the lifecycle of cluster blueprints with an "infrastructure administrator" role in the Org.

Step 1: Create or Update Custom Blueprint

As an Admin in the Web Console,

Creating A Blueprint

  • Navigate to the Project and click on Blueprints under Infrastructure
  • Click on New blueprint
  • Provide a name and description
  • Select the Type Custom Blueprint, which is selected by default and click Save
  • Click on New Version and use the wizard to provide details
  • Provide a version number/name
  • Select a Base Blueprint, either Default Blueprint (or) Golden Blueprint. See above for when you should use the default blueprint or golden blueprint.

New Blueprint

Updating A Blueprint

  • Navigate to the Project and click on Blueprints under Infrastructure
  • Click on your blueprint
  • Click on New Version and use the wizard to provide details
  • Provide a version number/name

Step 2: Enabling Key Services, Add-Ons, and Configurations

  • Next, let's see the optional functionality that can be enabled in terms of add-ons and services. If you do not want to enable any of this, you can click save changes.

New Blueprint

To view the Blueprint version changes (logs) performed on base blueprint, click Version Change Log. This shows the list of add-ons associated with each version

Blueprint Version Log

Golden Blueprint

To use Golden Blueprint as the base, select the Golden Blueprint option. Choose one of the existing golden blueprint and its version from the drop-down

Blueprint Version Log

Enabling Drift Detection (Optional)


  • Select a drift detection policy

Drift Detection


In alignment with the end of support for PSPs in Kubernetes, turnkey support for PSPs has been deprecated. New Blueprints will no longer support the use of PSP. Existing PSP configurations configured through Blueprints will be maintained but cannot be updated. PSP addons are therefore marked as ready instantly on any Blueprint updates

Enabling Namespace Syncing (Optional)


  • Enable Namespace sync under Namespace configuration

Namespace sync

Enabling Managed Services (Optional)

Optionally Rafay managed services can be enabled including:

  • Policy Management powered by OPA Gatekeeper: This enables OPA Gatekeeper on any cluster the blueprint is deployed to. Select policies from the list to enforce on the required cluster.
  • Network Policy powered by Cilium: Toggling the enable network visibility and policy installs Cilium on the cluster and allows admins to create and enforce Cilium network policies for namespace isolation and L3/L4 segmentation. Optionally, you can select cluster-wide policies to enforce by default as well as specifying a custom installation profile in case you want to change certain Cilium installation parameters.
  • Service Mesh powered by Istio: Toggling the enable button for Service Mesh installs Istio on the cluster the blueprint is deployed to. Optionally, you can select cluster-wide policies to enforce by default as well as specifying a custom installation profile in case you want to change certain Istio installation parameters.
  • Cost Management: Toggling the enable button here enables cost management to enforce chargeback rules and get visibility into overall cost metrics and usage on a given cluster.


Adding customized add-ons (Optional)

Next you can select which custom software add-ons you want to have as part of your blueprint allowing you to bring your own software or customizations as necessary. Refer to the custom add-on documentation for more info on how to create a custom add-on.

In order to use these custom add-ons in a blueprint:

  • Click Configure Add-Ons.

Configure Add On

  • Next search for the add-ons you want to use. You can search by name or search by label to reference a group of add-ons with the given label. Refer to to the custom add-on documentation for more info on how to create and use add on labels.
  • Next, you can select all from the search results or use the plus button to add the individual add-on. A few key things to note on this step: 1) When the add-on is selected, if not in the list already the latest version will be selected.
    2) When you select all, add-ons which do not have a version/are not fully initialized will not be added to the list. 3) If the add-on is already in the blueprint, the next time you update, it will still have the given version you selected.
  • If you need to change a version or specify a dependency on another add-on for any given particular add-on, you can do so by going to the individual add-on and making your modification.
  • Click the reset button to reset the list of add-ons selected if you want to start over.
  • Click SAVE CHANGES to save your changes.

Configure add on custom blueprint

Enabling Managed System Add-Ons and Fleet Configuration (Optional)

  • Enable/disable managed system addons from the default blueprint (i.e. Ingress Controller).
  • Select the required Kube API Proxy Network from the Private KubeAPI Proxy drop-down.
  • Add the required Fleet Values.
  • Enable Auto Update Clusters if any changes to the blueprint should automatically be applied to the selected fleet(s) of cluster(s).

Step 3: Saving Changes

  • Click save changes to save the configuration.

Create Blueprint


Custom Blueprints cannot override configurations specified in the Golden blueprint

View Versions

The entire history of blueprint versions is maintained on the Controller. Admins can view details about the versions of cluster blueprints.

Use the toggle button to enable or disable the required blueprint version(s) to list out during the cluster provisioning. This option helps to disallow the users from using blueprint versions that might contain vulnerable/deprecated Add-On versions.

View All Versions

Disabling affects the clusters using this specific blueprint version. Click Yes to proceed

View All Versions

Once a version is disabled, the cluster deployed with that specific BP version is highlighted in red with an Update button. Use this button to update with the required blueprint and version

View All Versions

BP Version with Fleet Values

The history of blueprint versions with fleet values is maintained on the controller.

Publish to Fleet

Blueprints with Fleet values show a publish icon.

  • Click the publish icon to manually publish the selected blueprint version to the fleet(s). Once a blueprint version is published to a fleet, a job is initiated.

View All Versions


If the Auto Update Clusters is enabled while creating a blueprint New Version, the new version is automatically published to the fleet(s). Users must manually publish the blueprint version to fleets if the Auto Update Clusters option is disabled

  • Click View Fleet Jobs to view the status of the job. The below example shows blueprint version 5 is successfully published to the fleets and in Ready status

View All Versions

  • Click the job id to view the list of clusters under this fleet

View All Versions


Users cannot publish the disabled blueprint versions to the fleets

Deployment Status

Once the blueprint version is published to the fleets, the job status varies based on the blueprint sync

Status Description
No Cluster No clusters available in the fleet(s)
Ready Blueprint publish is success on all fleet(s) of clusters
Partially Ready Blueprint published on a few clusters
In Progress Blueprint publishing on the fleet(s) in progress
Failed Blueprint publish failed on all fleets


Click the eye icon to view the blueprint version details

Filter Clusters by Blueprint

Infrastructure admins can "filter" clusters by blueprint name using the Web Console to manage a fleet of clusters efficiently. An illustrative example is shown below.

Filter Clusters by Blueprint

View All Cluster Blueprints

Admins can view all custom cluster blueprints.

  • Navigate to the Project
  • Click on Blueprints under Infrastructure

This will display both the "default blueprints" and any cluster blueprints that have been created. An illustrative example is shown below.

View Cluster Blueprints

Apply Custom Blueprint

Once a custom cluster blueprint has been created and published, it can be used during the initial provisioning of clusters or applied to existing clusters.

New Clusters

While creating a new cluster, select the "custom blueprint" from the dropdown. An illustrative example is shown below.

Blueprint for New Cluster

Existing Clusters

  • Click on options (gear icon on the far right) for an existing cluster
  • Select "Update Blueprint" from the options
  • Select the "blueprint" and "version" from the dropdown
  • Click on Save and Publish

Blueprint for Existing Cluster

This will update the cluster blueprint on the target cluster. Once all the required resources are operational on the cluster, the blueprint update/sync will be complete.


If the selected blueprint version has VM Operator enabled, minimum one node with label must be available in the selected cluster. This information is presented to the user when selecting the VM Operator is enabled in the blueprint version.

Status and Debug

In addition to using the Zero Trust KubeCTL channel for debugging and diagnostics, admins can also use the built-in status details if issues are encountered during a blueprint sync process with a cluster.

In the Blueprint Sync Status field on the cluster, click on the Status link. This will provide detailed status by component in the blueprint.

An illustrative example is shown below.

Deep Blueprint Status


In some scenarios, there are requirements that certain components (add-ons) need to be installed first before installing the rest of the components (add-ons).

To achieve this, define this dependency when creating the blueprint version. In the below example, install cert-manager before installing vault because vault uses cert-manager to create the certificate for Ingress.

  • Navigate to the Project
  • Click on Blueprints under Infrastructure
  • Click on New blueprint
  • Provide a name and description
  • Click Create
  • Click on New Version and use the wizard to provide details
  • Provide a version number/name
  • Under add-ons, select cert-manager and its version.
  • Select "ADD MORE" and then select Vault add-on from the dropdown and its version
  • Select "ADD DEPENDENCY" under Vault add-on and select "cert-manager"
  • Click "Save Changes"

add-on Dependency


If an add-on is dependent on multiple add-ons, all these add-ons can be added as dependencies
