Creating a Cluster

This topic summarizes the workflow to create and deploy a cluster, followed by procedure details. After adding your cloud credentials to Megaport ONE, you can deploy a cluster.

To begin, the basic steps are:

  1. Create a new cluster

  2. Deploy the cluster

  3. Add containerized applications to the cluster - For details, see Viewing and Managing Applications.

Creating a new cluster

To set up a new cluster, create the cluster and then perform these tasks:

  • Configure provider connection details - Megaport ONE provides seamless access to these hybrid and multicloud environments: Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform. Megaport ONE automates connections by predicting and applying best practice configurations. You can deploy a Kubernetes cluster to any Megaport ONE provider that your account credentials allow.

    Megaport ONE simplifies deployments for pre-existing cloud configurations by importing your preconfigured VPC, VNET, and VCN information. When you choose a cluster location, Megaport ONE queries the CSP using your cloud credentials to determine the VPCs, VNETs, or VCNs that exist in the selected location. Once Megaport ONE imports the resource details, you can build a cluster without returning to the provider to complete the configuration.

    For account credential details, see Adding Credentials.

  • Configure a node pool - A cluster unifies a node grouping of individual virtual or physical machines deployed in the same region into a pool. The nodes in a cluster are the machines that run the end-user applications.

To create a new cluster

  1. Log in to the Megaport ONE Portal.
  2. Choose Compute > Clusters.

  3. Click Deploy New Cluster.

    Create Cluster

  4. Enter a unique cluster name with a length of 5 t o 38 lowercase characters. Use lowercase letters, numbers, or hyphens. Don’t use dots, spaces, or underscores.

  5. Select a cloud, colocation, or edge provider.
    The list includes available providers based on your account credentials.

  6. Select a data center location for the cluster.
    The list includes available data center locations based on your account.
    To use a preconfigured cloud configuration, select the location of the pre-existing cloud resources.
    A GPU ENABLED flag appears next to locations with GPUSpecialized processors that provide computing power to process many pieces of data simultaneously, accelerating the workload and increasing performance. capabilities. Use GPUs for high-performance acceleration of a specific Kubernetes workload.

  7. A Kubernetes version is preselected for you based on available versions for your provider and location.
    The default selection is the best choice if you don’t have a specific need for an earlier version.

The next step is to configure provider connection details that connect the cluster compute resources with the service resource provider. The cluster can connect to any consumable endpoint, whether that is on-premises, public cloud, or bare metal.

Configuration details vary by provider.

To configure provider connection details

  • The configuration options reflect the required settings for your provider.

    • Amazon Web Services - Select a VPC and at least two AWS subnets for the cluster.
    • Google Cloud Platform - Select a Google VPC network and a subnet for the cluster.
    • Microsoft Azure - Select a network configuration using kubenet with a default VNet, or select a network configuration using Azure CNI with the option to customize your VNet.

The next step is to configure the node machine compute type that runs the underlying cluster.

Configure Node Pool

The machine type definition includes the CPU and memory specifications. Use the filter to limit the number of compute options returned by the provider.

Filters provide a way to find a GPU-enabled provider for high-performance acceleration of a specific Kubernetes workload. Select a resource from the GPU capabilities drop-down list to narrow your search.

All nodes in a pool group must be the same machine type.

For details on GPU resources, see Compute Locations.

To configure a node pool

  1. Select the number of CPU nodes and the minimum RAM.

  2. Select whether the node pool has GPU capabilities.
    The location description indicates its GPU capability.

  3. Select the machine type.
    A verification appears when the machine type is available in the selected location.
    A GPU type is automatically selected based on the machine type.

  4. Select the number of nodes in the pool.

  5. Enable or disable autoscaling.
    Autoscaling adjusts the size of a Kubernetes cluster by increasing or decreasing the number of nodes to meet the current demands for service. As conditions change, automatically scales the cluster nodes based on metrics such as CPU and RAM use.

    After enabling autoscaling, set the minimum and maximum number of nodes in the pool.

  6. Select Yes for direct access to the Kubernetes DashboardAn official web-based user interface (UI) designed especially for Kubernetes clusters to give Kubernetes administrators control of the clusters. from relevant pages to view details and troubleshoot the cluster in Megaport ONE using the browser. By default, the Kubernetes Dashboard is enabled.


    You can also access the Kubernetes Dashboard by clicking the cluster name on the Megaport ONE dashboard and then selecting Actions > Launch Kubernetes Dashboard.

Deploying a cluster

After creating a cluster, the next step is to deploy it. Deploying a cluster connects it to the provider and provisions the cluster on the account connected with the Megaport ONE instance.

To deploy a cluster

  1. Click Deploy Cluster.

    Review Cluster Config

  2. Review the configuration.

  3. Click Confirm to deploy the cluster or Cancel to change settings.

The cluster starts communicating with the provider and proceeds through the deployment process, which can take approximately 10 to 25 minutes, depending on the underlying provider’s current traffic level.

Click the status indicator to view the cluster deployment states.

Cluster Deployment States

After a successful cluster deployment, you can control it completely from the Megaport ONE platform. If you want more details and functionality, the Clusters page provides a direct link to the Kubernetes Dashboard.


If the deployment state of a cluster indicates an issue, the cluster could not be deployed. The status indicator reports any provisioning errors and where in the provisioning process the error occurred.

Cluster Deployment Error

To see status error details

  • Click the state indicator and click More Information.

The cause of the failure is listed to identify the problem.
