Astra Control Center requirements

Contributors netapp-mwallis

Get started by verifying the readiness of your operational environment, application clusters, applications, licenses, and web browser.

Operational environment requirements

Astra Control Center requires one of the following types of operational environments:

  • Red Hat OpenShift Container Platform 4.6.8, 4.7, or 4.8

  • Rancher 2.5

  • Kubernetes 1.19 to 1.21 (including 1.21.x)

Ensure that the operating environment you choose to host Astra Control Center meets the basic resource requirements outlined in the environment’s official documentation. Astra Control Center requires the following resources in addition to the environment’s resource requirements:

Component Requirement

Backend ONTAP storage capacity

At least 300GB available

Worker nodes

At least 3 worker nodes total, with 4 CPU cores and 12GB RAM each

Load balancer

Service type "LoadBalancer" available for ingress traffic to be sent to services in the operational environment cluster

FQDN resolution

A method for pointing the FQDN of Astra Control Center to the load balanced IP address

Astra Trident

  • Astra Trident 21.04 or newer installed and configured if NetApp ONTAP version 9.5 or newer will be used as a storage backend

  • Astra Trident 21.10.1 or newer installed and configured if Astra Data Store preview will be used as a storage backend

Note These requirements assume that Astra Control Center is the only application running in the operational environment. If the environment is running additional applications, adjust these minimum requirements accordingly.
  • Image registry: You must have an existing private Docker image registry to which you can push Astra Control Center build images. You need to provide the URL of the image registry where you will upload the images.

  • Astra Trident / ONTAP configuration: Astra Control Center requires that a storage class be created and set as the default storage class. Astra Control Center supports the following ONTAP drivers provided by Astra Trident:

    • ontap-nas

    • ontap-nas-flexgroup

    • ontap-san

    • ontap-san-economy

Note

During app cloning in OpenShift environments, Astra Control Center needs to allow OpenShift to mount volumes and change the ownership of files. Because of this, you need to configure an ONTAP volume export policy to allow these operations. You can do so with the following commands:

  1. export-policy rule modify -vserver <storage virtual machine name> -policyname <policy name> -ruleindex 1 -superuser sys

  2. export-policy rule modify -vserver <storage virtual machine name> -policyname <policy name> -ruleindex 1 -anon 65534

Note If you plan to add a second OpenShift operational environment as a managed compute resource, you need to ensure that the Astra Trident Volume Snapshot feature is enabled. To enable and test volume snapshots with Astra Trident, see the official Astra Trident instructions.

Application cluster requirements

Astra Control Center has the following requirements for clusters that you plan to manage from Astra Control Center. These requirements also apply if the cluster you plan to manage is the operational environment cluster that hosts Astra Control Center.

  • The most recent version of the Kubernetes snapshot-controller component is installed

  • An Astra Trident volumesnapshotclass object has been defined by an administrator

  • A default Kubernetes storage class exists on the cluster

  • At least one storage class is configured to use Astra Trident

Note Your application cluster should have a kubeconfig.yaml file that defines only one context element. Visit the Kubernetes documentation for information about creating kubeconfig files.
Note When managing application clusters in a Rancher environment, modify the application cluster’s default context in the kubeconfig file provided by Rancher to use a control plane context instead of the Rancher API server context. This reduces load on the Rancher API server and improves performance.

Application management requirements

Astra Control has the following application management requirements:

  • Licensing: To manage applications using Astra Control Center, you need an Astra Control Center license.

  • Namespaces: Astra Control requires that an app not span more than a single namespace, but a namespace can contain more than one app.

  • StorageClass: If you install an application with a StorageClass explicitly set and you need to clone the app, the target cluster for the clone operation must have the originally specified StorageClass. Cloning an application with an explicitly set StorageClass to a cluster that does not have the same StorageClass will fail.

  • Kubernetes resources: Applications that use Kubernetes resources not collected by Astra Control might not have full app data management capabilities. Astra Control collects the following Kubernetes resources:

    • ClusterRole

    • ClusterRoleBinding

    • ConfigMap

    • CustomResourceDefinition

    • CustomResource

    • DaemonSet

    • Deployment

    • DeploymentConfig

    • Ingress

    • MutatingWebhook

    • PersistentVolumeClaim

    • Pod

    • ReplicaSet

    • RoleBinding

    • Role

    • Route

    • Secret

    • Service

    • ServiceAccount

    • StatefulSet

    • ValidatingWebhook

Supported application installation methods

Astra Control supports the following application installation methods:

  • Manifest file: Astra Control supports apps installed from a manifest file using kubectl. For example:

    kubectl apply -f myapp.yaml
  • Helm 3: If you use Helm to install apps, Astra Control requires Helm version 3. Managing and cloning apps installed with Helm 3 (or upgraded from Helm 2 to Helm 3) is fully supported. Managing apps installed with Helm 2 is not supported.

  • Operator-deployed apps: Astra Control supports apps installed with namespace-scoped operators. The following are some apps that have been validated for this installation model:

Note An operator and the app it installs must use the same namespace; you might need to modify the deployment .yaml file for the operator to ensure this is the case.

Access to the internet

You should determine whether you have outside access to the internet. If you do not, some functionality might be limited, such as receiving monitoring and metrics data from NetApp Cloud Insights, or sending support bundles to the NetApp Support Site.

License

Astra Control Center requires an Astra Control Center license for full functionality. Obtain an evaluation license or full license from NetApp. Without a license, you will be unable to:

  • Define custom apps

  • Create snapshots or clones of existing apps

  • Configure data protection policies

If you want to try Astra Control Center, you can use a 90-day evaluation license.

Service type "LoadBalancer" for on-premises Kubernetes clusters

Astra Control Center uses a service of the type "LoadBalancer" (svc/traefik in the Astra Control Center namespace), and requires that it be assigned an accessible external IP address. If load balancers are permitted in your environment and you don’t already have one configured, you can use MetalLB to automatically assign an external IP address to the service. In the internal DNS server configuration, you should point the chosen DNS name for Astra Control Center to the load-balanced IP address.

Networking requirements

The operational environment that hosts Astra Control Center communicates using the following TCP ports. You should ensure that these ports are allowed through any firewalls, and configure firewalls to allow any HTTPS egress traffic originating from the Astra network. Some ports require connectivity both ways between the environment hosting Astra Control Center and each managed cluster (noted where applicable).
