Pre-provisioned Create a New Cluster

Create a Kubernetes cluster using the infrastructure definition

After you have defined the infrastructure and control plane endpoints, you can proceed to creating the cluster by following these steps to create a new pre-provisioned cluster.

Before you create a new DKP cluster below, you may choose an external load balancer or virtual IP and use the corresponding dkp create cluster command example from that page in the docs from the links below. Other customizations are available, but require different flags during dkp create cluster command also. Refer to corresponding section for custom cluster creation:

DKP uses localvolumeprovisioner as the default storage provider. However, localvolumeprovisioner is not suitable for production use. You should use a Kubernetes CSI compatible storage that is suitable for production.

You can choose from any of the storage options available for Kubernetes. To disable the default that Konvoy deploys, set the default StorageClasslocalvolumeprovisioner as non-default. Then set your newly created StorageClass to be the default by following the commands in the Kubernetes documentation called Changing the Default Storage Class.

  1. The following command relies on the pre-provisioned cluster API infrastructure provider to initialize the Kubernetes control plane and worker nodes on the hosts defined in the inventory.

    NOTE: When specifying the cluster-name, you must use the same cluster-name as used when defining your inventory objects.
    NOTE: (Optional) If you have overrides for your clusters, you must specify the secret as part of the create cluster command. If these are not specified, the overrides for your nodes will not be applied.

    NOTE: To increase Docker Hub's rate limit use your Docker Hub credentials when creating the cluster, by setting the following flag --registry-mirror-url= --registry-mirror-username= --registry-mirror-password= on the dkp create cluster command.
    NOTE: Ensure your subnets do not overlap with your host subnet because they cannot be changed after cluster creation. If you need to change the kubernetes subnets, you must do this at cluster creation. The default subnets used in DKP are:


    Create cluster command may take a while depending on the size of the cluster:

    dkp create cluster preprovisioned 
    --cluster-name ${CLUSTER_NAME} 
    --control-plane-endpoint-host <control plane endpoint host> 
    --control-plane-endpoint-port <control plane endpoint port, if different than 6443> 

    The output from this command is shortened here for reading clarity, but should start like this:

    Generating cluster resources created
  2. Use the wait command to monitor the cluster control-plane readiness:

    kubectl wait --for=condition=ControlPlaneReady "clusters/${CLUSTER_NAME}" --timeout=30m


    CODE condition met
  3. If your cluster is in an air-gapped environment or you have a local registry, you must provide additional arguments when creating the cluster. These tell the cluster where to locate the local registry to use by defining the URL.

    export REGISTRY_URL="<https/http>://<registry-address>:<registry-port>"
    export REGISTRY_CA="<path to the CA on the bastion>"
    export REGISTRY_USERNAME="<username>"
    export REGISTRY_USERNAME="<password>"
  • REGISTRY_URL: the address of an existing container registry accessible in the VPC that the new cluster nodes will be configured to use a mirror registry when pulling images.

  • REGISTRY_CA: (optional) the path on the bastion machine to the container registry CA. Konvoy will configure the cluster nodes to trust this CA. This value is only needed if the registry is using a self-signed certificate and the AMIs are not already configured to trust this CA.

  • REGISTRY_USERNAME: optional, set to a user that has pull access to this registry.

  • REGISTRY_PASSWORD: optional if username is not set.

dkp create cluster preprovisioned --cluster-name ${CLUSTER_NAME} \
--control-plane-endpoint-host <control plane endpoint host> \
--control-plane-endpoint-port <control plane endpoint port, if different than 6443> \
--registry-mirror-url=${REGISTRY_URL} \
--registry-mirror-cacert=${REGISTRY_CA} \
--registry-mirror-username=${REGISTRY_USERNAME} \

NOTE: Depending on the cluster size, it will take a few minutes to create.

4. After the creation, use this command to get the Kubernetes kubeconfig for the new cluster and begin deploying workloads:

dkp get kubeconfig -c ${CLUSTER_NAME} > ${CLUSTER_NAME}.conf

Azure requires changing the CNI encapsulation type of Calico from the default of IPtoIP to VXlan. If changing the Calico encapsulation, D2iQ recommends changing it after cluster creation, but before production.
