DESCRIPTION ----------- -This unbound (dns resolver and cache) deployment provides DNS64 and fetch -answers from specified upstrean DNS server. This is a singleton type. +This type writes the configuration and OpenRC init scripts to run an instance +of unbound. The most commonly used options for unbound are configurable through +flags. + +Note that this type is currently only implemented (and tested) on Alpine Linux. +Please contribute other implementations if you can. -REQUIRED PARAMETERS -------------------- -forward_addr - DNS servers used to lookup names, can be provided multiple times. It can be - either an IPv4 or IPv6 address but no domain name. OPTIONAL PARAMETERS ------------------- -interface - Interface to listen on, can be provided multiple times. Defaults to - '127.0.0.1' and '::1'. +verbosity + Control the `unbound.conf(5)` verbosity parameter. -access-control - Controls which clients are allowed queries to the unbound service (everything - but localhost is refused by default), can be provided multiple times. The - format is described in unbound.conf(5). +port + Control the `unbound.conf(5)` port parameter. -rc-interface - Address or path to socket used for remote control (see `--enable_control`. Defaults to `127.0.0.1`). - -local-data - Configure local data, which is served in reply to queries for it. Can be - specified multiple times. +control-port + Control the `unbound.conf(5)` control-port parameter. dns64-prefix - Enable DNS64 with specified prefix. + Control the `unbound.conf(5)` dns64-prefix parameter. + +OPTIONAL MULTIPLE PARAMETERS +---------------------------- +interface + Control the `unbound.conf(5)` interface parameter. Can be + given multiple times, will generate multiple `interface: + xxx` clauses. + +access-control + Control the `unbound.conf(5)` access-control parameter. Can be given + multiple times, will generate multiple `access-control` clauses. The format + is an IP block followed by an access-control keyword. + +control-interface + Control the `unbound.conf(5)` control-interface parameter. Can be given + mutltiple times, will generate multiple `control-interface` clauses. Note + that without the `enable-rc` boolean flags, remote control will not be + enabled. Note that if at least one control interfaces is not a local socket, + then you should enable the `control-use-certs` boolean flag to generate and + configure TLS certificates for use between `unbound(8)` and + `unbound-control(8)` + +forward-zone + Define a forward zone. Each zone is comprised of a name, which defines for + what domains this zone applies, and at least one DNS server to which the + queries should be forwarded. The format is a comma-separated list of values + where the first element is the name of the zone, and the following elements + are the IP addresses of the DNS servers; e.g. `example.com,1.2.3.4,4.3.2.1` + +local-data + Control the `unbound.conf(5)` local-data parameter. Note that no local-zone + is defined, so the unbound default is to treat this data as a transparent + local zone. BOOLEAN PARAMETERS ------------------ -disable-ip4 - Do not answer or issue queries over IPv4. Cannot be used alongside the - `--disable-ip6` flag. +ip-transparent + Control the `unbound.conf(5)` ip-transparent parameter. -disable-ip6 - Do not answer or issue queries over IPv6. Cannot be used alongside the - `--disable-ip4` flag. +dns64 + Enables the addition of the DNS64 module. enable-rc - Enable remote control (see `unbound-control(8)`). + Enable remote control. + +control-use-certs + Enable the generation using `unbound-control-setup(8)` of TLS certificates + for the interaction between `unbound(8)` and `unbound-control(8)`, as well as + their inclusion in the configuration file. + +disable-ip4 + Disable answering queries over IPv4. + +disable-ip6 + Disable answering queries over IPv6.
