Parameters:

• devices (Hash) —

  The devices that wil be managed by this class

• api_manager_prefix (String) —

  Prefix that will be added to the description fields for non exported resource items

• manage_resources (Boolean) —

  When true, it will export resources to something like puppetdb. When set to true, you’ll need to configure ‘storeconfigs’ to make this happen. Default is set to false, as not everyone has this enabled.

• required_plugins (Hash) —

  The required opnsense plugins to support all features.

• firewall (Hash) —

  Configured the opnsense firewall.

• haproxy (Hash) —

  Configured the opnsense haproxy loadbalancer.

• manage_ca (Boolean) —

  When true, the CA file used by opn-cli will be managed to ensure that the communication to the OPNsense API is possible.

• ca_content (Optional[String]) —

  A string containing a CA certificate that should be written to the file specified in ‘$ca_file`.

• ca_file (Stdlib::Absolutepath) —

  The absolute path to the CA file that should be used by opn-cli.

• use_system_ca (Boolean) —

  This instructs opn-cli to use the system-wide installed CA certificates when verifying the connection to the OPNsense API.

• system_ca_file (Stdlib::Absolutepath) —

  The absolute path to the system-wide CA certificate file.

• opncli_configdir (Stdlib::Absolutepath) —

  The config directory used by opn-cli.
