Sample High Availability Configurations
This section provides a sample SMI Cluster Manager HA configuration with an Active and Standby nodes. The following parameters are used in this HA configuration:
-
Active Node Host Name: ha-active
-
Standby Node Host Name: ha-standby
-
Primary IP address for Active Node: <Primary_active_node_IPv4address>
-
Primary IP address for Standby Node: <Primary_standby_node_IPv4address>
-
Virtual IP address: <Virtual_IPv4address>
Defining a High Availability Configuration
The following examples defines the virtual IP address for the cluster named ha.
clusters ha
configuration master-virtual-ip <Virtual_IPv4address>
...
The following examples defines the two HA nodes.
nodes active
ssh-ip <Primary_active_node_IPv4address>
type k8s
k8s node-type control-plane
k8s hostname-override ha-active
k8s ssh-ip <Primary_active_node_IPv4address>
k8s node-ip <Virtual_IPv4address>
...
exit
nodes standby
ssh-ip <Primary_standby_node_IPv4address>
type k8s
k8s node-type backup
k8s ssh-ip <Primary_standby_node_IPv4address>
k8s node-ip <Virtual_IPv4address>
...
exit
