Create Clusters

You can create a new Kubernetes cluster in your Hostman control panel.

1. Go to the Kubernetes section.

2. Click Create or Add.

3. Specify the cluster parameters.

a. Select the Kubernetes version. Note that you won't be able to change it later.

b. Select one the following master node configurations:

• • Dev: supports up to 10 worker nodes. Uses a single master node with the parameters: 2 CPU, 2 GB RAM, 30 GB NVMe.
  • Base: supports up to 100 worker nodes. Uses a single master node with the parameters: 4 CPU, 8 GB RAM, 60 GB NVMe.
  • Custom: allows you to select 1 or 3 master nodes and configure worker nodes manually.

Here you can also set the cluster maintenance window, i.e. the time period during which system updates are allowed:

• Never
• Anytime
• At a specified time

During the maintenance window, Hostman may update certificates and install security patches. Updates may affect both master and worker nodes. During this time, you won't be able to manage the cluster  in the control panel. Brief service interruptions are possible.

You can always change the preferred maintenance window later, in the cluster settings.

4. Select worker nodes configuration. Create one or more node groups, select the number of nodes in each group, and choose a plan for them.

5. Select an existing private network or create a new one. If necessary, configure a CNI plugin. It ensures full network connectivity between cluster nodes and affects the scalability and flexibility of network policy configuration.

6. Configure add-ons. You can install Nginx Ingress, Kubernetes Dashboard, and connect an OIDC provider. You can also install and remove the addons any time later. 

7. Fill in the cluster information (name, comment, project) and click Order. The cluster creation will take a few minutes, after which you can start working.
