Modules & Configuration

Goldilocks has several core systems, which all have their own configuration and some of which have modules:

All modules require a type and an id, and any modules not defined inside the domains system also require a domains field (with the exception of the forward modules that require the ports field).

http

The HTTP system handles plain http (TLS / SSL is handled by the tls system)

Example config:

http:
  trust_proxy: true                 # allow localhost, 192.x, 10.x, 172.x, etc to set headers
  allow_insecure: false             # allow non-https even without proxy https headers
  primary_domain: example.com       # attempts to access via IP address will redirect here

  # An array of modules that define how to handle incoming HTTP requests
  modules:
    - type: static
      domains:
        - example.com
      root: /srv/www/:hostname

http.proxy - how to reverse proxy (ruby, python, etc)

The proxy module is for reverse proxying, typically to an application on the same machine. (Though it can also reverse proxy to other devices on the local network.)

It has the following options:

address     The DNS-resolvable hostname (or IP address) and port connected by `:` to proxy the request to.
            Takes priority over host and port if they are also specified.
            ex: locahost:3000
            ex: 192.168.1.100:80

host        The DNS-resolvable hostname (or IP address) of the system to which the request will be proxied.
            Defaults to localhost if only the port is specified.
            ex: localhost
            ex: 192.168.1.100

port        The port on said system to which the request will be proxied
            ex: 3000
            ex: 80

Example config:

http:
  modules:
    - type: proxy
      domains:
        - api.example.com
      host: 192.168.1.100
      port: 80
    - type: proxy
      domains:
        - www.example.com
      address: 192.168.1.16:80
    - type: proxy
      domains:
        - '*'
      port: 3000

http.static - how to serve a web page

The static module is for serving static web pages and assets and has the following options:

root        The path to serve as a string.
            The template variable `:hostname` represents the HTTP Host header without port information
            ex: `root: /srv/www/example.com` would load the example.com folder for any domain listed
            ex: `root: /srv/www/:hostname` would load `/srv/www/example.com` if so indicated by the Host header

Example config:

http:
  modules:
    - type: static
      domains:
        - example.com
      root: /srv/www/:hostname

http.redirect - how to redirect URLs

The redirect module is for, you guessed it, redirecting URLs.

It has the following options:

status      The HTTP status code to issue (301 is usual permanent redirect, 302 is temporary)
            ex: 301

from        The URL path that was used in the request.
            The `*` wildcard character can be used for matching a full segment of the path
            ex: /photos/
            ex: /photos/*/*/

to          The new URL path which should be used.
            If wildcards matches were used they will be available as `:1`, `:2`, etc.
            ex: /pics/
            ex: /pics/:1/:2/

Example config:

http:
  modules:
    - type: proxy
      domains:
        - example.com
      status: 301
      from: /archives/*/*/*/
      to: https://example.net/year/:1/month/:2/day/:3/

tls

The tls system handles encrypted connections, including fetching certificates, and uses ServerName Indication (SNI) to determine if the connection should be handled by the http system, a tls system module, or rejected.

Example config:

tls:
  modules:
    - type: proxy
      domains:
        - example.com
        - example.net
      address: '127.0.0.1:6443'

Certificates are saved to ~/acme, which may be /var/www/acme if Goldilocks is run as the www-data user.

tls.proxy

The proxy module routes the traffic based on the ServerName Indication (SNI) without decrypting it.

It has the same options as the HTTP proxy module.

Example config:

tls:
  modules:
    - type: proxy
      domains:
        - example.com
      address: '127.0.0.1:5443'

tls.acme

The acme module defines the setting used when getting new certificates.

It has the following options:

email              The email address for ACME certificate issuance
                   ex: john.doe@example.com

server             The ACME server to use
                   ex: https://acme-v01.api.letsencrypt.org/directory
                   ex: https://acme-staging.api.letsencrypt.org/directory

challenge_type     The ACME challenge to request
                   ex: http-01, dns-01, tls-01

Example config:

tls:
  modules:
    - type: acme
      domains:
        - example.com
        - example.net
      email: 'joe.shmoe@example.com'
      server: 'https://acme-staging.api.letsencrypt.org/directory'
      challenge_type: 'http-01'

tcp

The tcp system handles all tcp network traffic before decryption and may use port numbers or traffic sniffing to determine how the connection should be handled.

It has the following options:

bind      An array of numeric ports on which to bind
          ex: 80

Example Config:

tcp:
  bind:
    - 22
    - 80
    - 443
  modules:
    - type: forward
      ports:
        - 22
      address: '127.0.0.1:2222'

tcp.forward

The forward module routes traffic based on port number without decrypting it.

In addition to the same options as the HTTP proxy module, the TCP forward modules also has the following options:

ports       A numeric array of source ports
            ex: 22

Example Config:

tcp:
  bind:
    - 22
    - 80
    - 443
  modules:
    - type: forward
      ports:
        - 22
      port: 2222

udp

The udp system handles all udp network traffic. It currently only supports forwarding the messages without any examination.

It has the following options:

bind      An array of numeric ports on which to bind
          ex: 53

Example Config:

udp:
  bind:
    - 53
  modules:
    - type: forward
      ports:
        - 53
      address: '127.0.0.1:8053'

udp.forward

The forward module routes traffic based on port number without decrypting it.

It has the same options as the TCP forward module.

Example Config:

udp:
  bind:
    - 53
  modules:
    - type: forward
      ports:
        - 53
      address: '127.0.0.1:8053'

domains

To reduce repetition defining multiple modules that operate on the same domain name the domains field can define multiple modules of multiple types for a single list of names. The modules defined this way do not need to have their own domains field.

Example Config

domains:
  names:
    - example.com
    - www.example.com
    - api.example.com
  modules:
    tls:
      - type: acme
        email: joe.schmoe@example.com
        challenge_type: 'http-01'
    http:
      - type: redirect
        from: /deprecated/path
        to: /new/path
      - type: proxy
        port: 3000

tunnel_server

The tunnel server system is meant to be run on a publicly accessible IP address to server tunnel clients which are behind firewalls, carrier-grade NAT, or otherwise Internet-connect but inaccessible devices.

It has the following options:

secret          A 128-bit or greater string to use for signing tokens (HMAC JWT)
                ex: abc123

servernames     An array of string servernames that should be captured as the
                tunnel server, ignoring the TLS forward module
                ex: api.tunnel.example.com

Example config:

tunnel_server:
  secret: abc123def456ghi789
  servernames:
    - 'api.tunnel.example.com'

tunnel

The tunnel client is meant to be run from behind a firewalls, carrier-grade NAT, or otherwise inaccessible devices to allow them to be accessed publicly on the internet.

It has no options per se, but is rather a list of tokens that can be used to connect to tunnel servers. If the token does not have an aud field it must be provided in an object with the token provided in the jwt field and the tunnel server url provided in the tunnelUrl field.

Example config:

tunnel:
  - 'some.jwt_encoded.token'
  - jwt: 'other.jwt_encoded.token'
    tunnelUrl: 'wss://api.tunnel.example.com/'

ddns

TODO

mdns

enabled by default

Although it does not announce itself, Goldilocks is discoverable via mDNS with the special query _cloud._tcp.local. This is so that it can be easily configured via Desktop and Mobile apps when run on devices such as a Raspberry Pi or SOHO servers.

mdns:
  disabled: false
  port: 5353
  broadcast: '224.0.0.251'
  ttl: 300

You can discover goldilocks with mdig.

npm install -g git+https://git.daplie.com/Daplie/mdig.git

mdig _cloud._tcp.local

socks5

Run a Socks5 proxy server.

socks5:
  enable: true
  port: 1080

api

See API.md

@tigerbot: How are the APIs used (in terms of URL, Method, Headers, etc)?

TODO

  • http - nowww module
  • http - Allow match styles of www.*, *, and *.example.com equally
  • http - redirect based on domain name (not just path)
  • tcp - bind should be able to specify localhost, uniquelocal, private, or ip
  • tcp - if destination host is omitted default to localhost, if dst port is missing, default to src
  • sys - curl https://daplie.me/goldilocks | bash -s example.com
  • oauth3 - example.com/.well-known/domains@oauth3.org/directives.json
  • oauth3 - commandline questionnaire
  • modules - use consistent conventions (i.e. address vs host + port)
    • tls - tls.acme vs tls.modules.acme
  • tls - forward should be able to match on source port to reach different destination ports
