Create a container cluster

Restrictions and guidelines

The system time of all nodes used for cluster creation must be consistent with the master cluster, with a time difference of less than 10 seconds.

Prerequisites

To create a container cluster for applications or services:

1. Make sure you have a minimum of three nodes to act as the controller nodes, with one being the master node.

2. Install a system ISO image on each node.

Procedure

1. On the top navigation bar, click Resources.

2. From the left navigation pane, select Containers.

3. Click Create Cluster.

4. Configure the cluster:

Parameter	Description
Cluster Name	Assign a name to the cluster.
Description	Enter a description of the cluster for the ease of management.
VIP	Specify the virtual IP (VIP) at which the cluster is accessible.
Master Node	Enter the IP address of the master controller node.
Controller Nodes	Enter the IP addresses of non-master controller nodes. You must add a minimum of two non-master controller nodes to a container cluster. To add more non-master controller nodes, click Add. Make sure the total number of the master controller node and non-master controller nodes is odd.

 

Then, the system automatically tests network connectivity and node availability.

5. In the dialog box that opens, click OK.
