Create

Each virtual cluster that is created in vCluster.Pro belongs to a Project. There are two primary ways which virtual clusters can be created inside vCluster.Pro: from a template, and manually.

Virtual clusters created from a template inherit all template settings. Regular project users (non project admins) are only allowed to create virtual clusters from templates that the project administrator has allowed. This ensures that virtual clusters in each project adhere to the standards set by the project owner.

Project owners and vCluster.Pro admins can create virtual clusters manually, that is without a template.

Create From Template

Project members can create a new virtual cluster through the vCluster.Pro UI or CLI:

  1. Select the Projects field on the left menu bar.
  2. From the project drop-down menu, select the project you'd like to create the virtual cluster in.
  3. Click the Virtual Clusters option on the project pane.
  4. Click the button on the right side of the page.
  5. In the pop-up box, select your template from the template drop down menu.
  6. [Optional] select the cluster in which to create the virtual cluster.
  7. Click the to continue.
  8. In the drawer that appears from the right, give your virtual cluster a name by replacing the my-vcluster placeholder name, or by updating the manifest YAML metadata.name field.
  9. Click the button.
  10. Retrieve a kube-context for a virtual cluster using vCluster.Pro CLI:

    vcluster connect [vcluster-name] --project [project-name]
Template Version Strings

Regardless of how you create a virtual cluster from a template, either by the UI or the CLI, vCluster.Pro allows you to provide a template version string. If you do not provide this string, the latest version will be automatically selected for you. If you do provide the string though, you can do something very neat -- you can set any of the MAJOR, MINOR, PATCH version components to an X wildcard character. This allows the virtual cluster to be automatically updated to a more recent template version that matches your provided template string.

For example, given a template with a version of 1.0.0, and a virtual cluster created from this template with a version string "1.X.X". Adding a new template version "1.1.0", will cause this virtual cluster to be automatically updated. Whereas adding a new version "2.0.0", will not cause the virtual cluster to be upgraded.

This is a very handy way to keep virtual clusters up to date with the latest templates without having to manually upgrade them!

Note that you can even set the version to "X.X.X" to always have your virtual cluster updated to the latest template version!

Create Without Template

Only Project admins can create a virtual cluster without a template:

  1. Select the Projects field on the left menu bar.
  2. From the project drop-down menu, select the project you'd like to create the virtual cluster in.
  3. Click the Virtual Clusters option on the project pane.
  4. Click the button on the right side of the page.
  5. In the popup make sure the virtual cluster template field is empty.
  6. [Optional] select the cluster in which to create the virtual cluster.
  7. Click the to continue.
  8. In the drawer that appears from the right, give your virtual cluster a name by replacing the my-vcluster placeholder name, or by updating the manifest YAML metadata.name field.
  9. [Optional] Update the virtual cluster with any additional desired configuration options.
    1. The Definition tab contains settings relating to the virtual cluster deployment itself, here you can provide helm values to be used when deploying the virtual cluster, select the virtual cluster distribution (ex: k3s (default), k0s, k8s), as well as configurations for sleep mode and ingress access.
    2. Objects is where you can define Kubernetes manifests that should be created in the virtual cluster.
    3. Apps allows you to select any pre-defined 'applications' (ex: Cert Manager) that should be installed into the virtual cluster.
    4. Space settings allow for configuration of labels and annotations on the space that the virtual cluster will be created in, you can also define objects and Apps that should be deployed into this space.
    5. Permissions are additional access rules that can be defined for the virtual cluster instance.
  10. Click the button.
  11. Retrieve a kube-context for a virtual cluster using vCluster.Pro CLI:

    vcluster connect [vcluster-name] --project [project-name]
