Issues with creating new clusters

When you create a new cluster, you should always use the latest release. If something doesn't work, check out the known issues.

Azure: Resource Providers can't be registered

On Azure, you may receive the following error when running create or terminate with limited IAM permissions:

Error: Error ensuring Resource Providers are registered.

Terraform automatically attempts to register the Resource Providers it supports to
ensure it's able to provision resources.

If you don't have permission to register Resource Providers you may wish to use the
"skip_provider_registration" flag in the Provider block to disable this functionality.


To continue, please ensure that the required resource providers have been registered in your subscription by your administrator.

Afterward, set ARM_SKIP_PROVIDER_REGISTRATION=true as an environment variable and either run create or terminate again. For example:

ARM_SKIP_PROVIDER_REGISTRATION=true constellation create --control-plane-nodes 1 --worker-nodes 2 -y

Or alternatively, for terminate:

ARM_SKIP_PROVIDER_REGISTRATION=true constellation terminate

Cloud logging

To provide information during early stages of the node's boot process, Constellation logs messages into the cloud providers' log systems. Since these offerings aren't confidential, only generic information without any sensitive values are stored. This provides administrators with a high level understanding of the current state of a node.

You can view these information in the follow places:

  1. In your Azure subscription find the Constellation resource group.
  2. Inside the resource group find the Application Insights resource called constellation-insights-*.
  3. On the left-hand side go to Logs, which is located in the section Monitoring.
    • Close the Queries page if it pops up.
  4. In the query text field type in traces, and click Run.

To find the disk UUIDs use the following query: traces | where message contains "Disk UUID"

Connect to nodes

Debugging via a shell on a node is directly supported by Kubernetes.

  1. Figure out which node to connect to:

    kubectl get nodes
    # or to see more information, such as IPs:
    kubectl get nodes -o wide
  2. Connect to the node:

    kubectl debug node/constell-worker-xksa0-000000 -it --image=busybox

    You will be presented with a prompt.

    The nodes file system is mounted at /host.

  3. Once finished, clean up the debug pod:

    kubectl delete pod node-debugger-constell-worker-xksa0-000000-bjthj
