High Availability Support for CN-Series Firewall as a Kubernetes CNF
High availability (HA) is a configuration in which two firewalls are placed in a group and their configuration is synchronized to prevent a single point of failure on your network. A heartbeat connection between the firewall peers ensures seamless failover in the event that a peer goes down. Setting up the firewalls in a two-device cluster provides redundancy and allows you to ensure business continuity.
You can now deploy the CN-series-as-a-kubernetes-CNF in HA. This mode of deployment supports only active/passive HA with session and configuration synchronization.
When you deploy the CN-Series-as-a-Kubernetes CNF in HA, there will be two PAN-CN-MGMT-CONFIGMAP, PAN-CN-MGMT, and PAN-CN-NGFW YAML files each for active and passive nodes.
To successfully deploy the CN-Series firewall as a Kubernetes CNF in HA with layer 3 support:
- In HA, each Kubernetes node should have at least three interfaces: Management (default), HA2 interface, and data interface.
- For CN-Series firewall in L3 mode, there should be at least two interfaces: Management (default) and data interface.
- Modify the new Network Attachment definition YAML files with the following changes:
- Ensure that thePAN_HA_SUPPORTparameter value isin the following YAML files:truepan-cn-mgmt-configmap-0.yamlpan-cn-mgmt-configmap-1.yamlRetrieve thevalue from the hypervisor interface running the following command:pciBusIDethtool -i interface nameAdd the above retrievedvalue to the following Network definition files:pciBusIDnet-attach-def-1.yamlnet-attach-def-2.yamlnet-attach-def-3.yamlnet-attach-def-ha2-0.yamlnet-attach-def-ha2-1.yamlRetrieve the static IP address of the HA2 interface from the corresponding node instance on the AWS console and add it to theaddressparameter ofnet-attach-def-ha2-0.yamlandnet-attach-def-ha2-1.yamlfile.
