NAME

wg-meta

DESCRIPTION

An approach to add metadata to the main wireguard config, written in Perl.

HIGHLIGHTS

  • Compatible with your existing setup (no configuration changes needed).

  • A CLI interface with abilities to set, enable, disable and apply your wireguard config(s).

  • A fancy show output which combines the meta-data, running-config and static-configs

  • Modular structure: The whole parser is independent of the CLI module - and can be used as a standalone library.

  • The config parser/writer and as well as the wg show dump parser are independent too. For more info, please refer to Wireguard::WGmeta::Wrapper::Config and Wireguard::WGmeta::Wrapper::Show

  • No external dependencies, runs on plain Perl (>=v5.22)!

INSTALLATION

        # Build from source
        perl Makefile.PL
        make test
        make install

        # Using `.deb` package (available in the linked git repo)
        sudo dpkg -i wg-meta_X.X.X.deb

ENVIRONMENT VARS

  • WIREGUARD_HOME: Directory containing the Wireguard configuration -> Make sure the path ends with a `/`. Defaults to /etc/wireguard/.

  • IS_TESTING: When defined, it has the following effects:

    • Commands::Set|Enable|Disable omits the header of the generated configuration files.

    • Line of code is shown for warnings and errors.

  • WG_NO_COLOR: If defined, the show command does not prettify the output with colors.

SYNOPSIS

Intended to use as command wrapper for the wg show and wg set commands. Support for wg-quick is enabled by default.

Please note that all attributes have to be specified in the `wg set` _syntax_, which means _AllowedIPs_ becomes allowed-ips and so on.

        sudo wg-meta show

        # output
        interface: wg0

        sudo wg-meta set wg0 peer +qz742hzxD3E5z5QF7VOvleVS1onavQpXBK3NdTh40g= name Fancy_meta_name

        # Access using alias
        sudo wg-meta set wg0 some_alias description "Some Desc"

        # Disable peer
        sudo wg-meta disable wg0 some_alias

        # Enable peer
        sudo wg-meta enable wg0 +qz742hzxD3E5z5QF7VOvleVS1onavQpXBK3NdTh40g=

        # Apply config
        sudo wg-meta apply wg0

UNDER THE HOOD

The main advantage is that this tool is not dependent on any other storage, metadata is stored inside the corresponding wgXX.conf file (Metadata is prefixed with #+):

        [Interface]
        #+Alias = some_alias
        #+Description = Some Desc
        Address = 10.0.0.7/24
        ListenPort = 6666
        PrivateKey = WEkEJW3b4TDmRvN+G+K9elzq52/djAXT+LAB6BSEUmM=

        [Peer]
        #+Name = Fancy_meta_name
        PublicKey = +qz742hzxD3E5z5QF7VOvleVS1onavQpXBK3NdTh40g=
        AllowedIPs = 0.0.0.0/0
        Endpoint = wg.example.com
