3. Click Roll out

Wait some minutes for your cluster to become ready.

Connect to the Cluster

Once your cluster is ready, grab the .kubeconfig (Admin) file from the Info page, which will grant you full access to the cluster.

$ export KUBECONFIG=/path/to/my/cluster.kubeconfig
$ kubectl cluster-info
Kubernetes control plane is running at ...

$ kubectl get nodes
# no nodes created yet

Before starting to deploy workloads, Machine Pools and Machines must be created and assigned.

INFO

meltcloud Clusters do not come with any CNI preinstalled. To put your Nodes into ready state, a CNI must be configured and deployed first!
