fck-nat Configuration

Configuration file

Upon starting, fck-nat evaluates a configuration file describing how the instance should behave as well as what features shall be enabled. To configure fck-nat, ensure a file /etc/fck-nat.conf exists with your configuration. fck-nat requires the service to be restarted by running service fck-nat-resart. In most implementations this configuration is passed only once via EC2's user data.

The following describes available options: | name | description | | ----------------------- | ----------- | | eni_id | The ID of the Elastic Network Interface to attach to the instance and use as a consistent endpoint to send traffic to fck nat. This is required when using high-availability mode. | | eip_id | The ID of an Elastic IP to be attached to the public network interface. This ensures the NAT gateway public traffic is always routed through the same public IP address. | | cwagent_enabled | If set, enables Cloudwatch agent and forward instance metrics to Cloudwatch. Requires cwagent_cfg_param_name to be set. | | cwagent_cfg_param_name | The name of the SSM Parameter holding the Cloudwatch agent configuration and which the agent shall pull from. Requires cwagent_enabled to be set. |
