To create a cluster, proceed as follows:
You are in the section Container Cluster > Cluster.
Enter the desired cluster name.
Select a configuration.
Optional: Select a public key in the Select SSH key field. Alternatively, you can create or import a new SSH key.
Please note:Public key authentication is an authentication method that lets you log in securely without a password. This method uses a private and a public key to authenticate users. The public key must be stored in the Cloud Panel to configure key-based authentication on the server. The public key is then automatically entered into the file root/.ssh/authorized_keys. The private key is saved locally on your computer and can also be assigned a password for added security.
Please note: The private key cannot be recovered from 1&1 IONOS. Therefore, make sure that the private key is stored on your local computer and kept secure.
Select the desired solution(s) and click Update Solutions.
Please note: If you install and enable autoscaling, Kubernetes will automatically add a new node to your existing cluster if the existing resources are not sufficient to run a new pod. The costs are calculated by the minute.
Please note: Some solutions require persistent storage to store data permanently. If you select such a solution (for example, Kubeless), a block of the required size is automatically displayed in the summary. Once you create the cluster, it will also create the required block storage. The block storage is displayed in the Infrastructure > Block Storage area after creation.
Select the desired data center, operating system, and Kubernetes version.
The cluster will be created.
