==========
|
|
|
|

Modules & Configuration
|
|
-----
|
|
|
|
Goldilocks has several core systems, which all have their own configuration and some of which have modules:
|
|
|
|
```
|
|
* http
|
|
- static
|
|
- redirect
|
|
- proxy (reverse proxy)
|
|
* tls
|
|
- acme
|
|
- proxy (reverse proxy)
|
|
* tcp
|
|
- forward
|
|
* tunnel_server
|
|
* tunnel_client
|
|
* mdns
|
|
* api
|
|
```
|
|
|
|
### http
|
|
|
|
The HTTP system handles plain http (TLS / SSL is handled by the tls system)
|
|
|
|
```yml
|
|
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
|
|
|
|
# modules can be nested in domains
|
|
domains:
|
|
- names:
|
|
- example.com
|
|
modules:
|
|
- name: static
|
|
root: /srv/www/:hostname
|
|
|
|
# The configuration above could also be represented as follows:
|
|
modules:
|
|
- name: static
|
|
domains:
|
|
- example.com
|
|
root: /srv/www/:hostname
|
|
```
|
|
|
|
### 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:
|
|
|
|
```yml
|
|
http:
|
|
modules:
|
|
- name: 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.
|
|
|
|
It has the following options:
|
|
|
|
```
|
|
host The DNS-resolvable hostname (or IP address) of the system to which the request will be proxied
|
|
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:
|
|
|
|
```yml
|
|
http:
|
|
modules:
|
|
- name: proxy
|
|
domains:
|
|
- example.com
|
|
host: localhost
|
|
port: 3000
|
|
```
|
|
|
|
### 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:
|
|
|
|
```yml
|
|
http:
|
|
modules:
|
|
- name: 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.
|
|
|
|
It has the following options:
|
|
|
|
```
|
|
acme.email The default email address for ACME certificate issuance
|
|
ex: john.doe@example.com
|
|
|
|
acme.server The default ACME server to use
|
|
ex: https://acme-v01.api.letsencrypt.org/directory
|
|
ex: https://acme-staging.api.letsencrypt.org/directory
|
|
|
|
acme.challenge_type The default ACME challenge to request
|
|
ex: http-01, dns-01, tls-01
|
|
|
|
acme.approved_domains The domains for which to request certificates
|
|
ex: example.com
|
|
```
|
|
|
|
Example config:
|
|
|
|
```yml
|
|
tls:
|
|
acme:
|
|
email: 'joe.shmoe@example.com'
|
|
# IMPORTANT: Switch to in production 'https://acme-v01.api.letsencrypt.org/directory'
|
|
server: 'https://acme-staging.api.letsencrypt.org/directory'
|
|
challenge_type: 'http-01'
|
|
approved_domains:
|
|
- example.com
|
|
- example.net
|
|
|
|
modules:
|
|
- name: 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.acme
|
|
|
|
The acme module overrides the acme defaults of the tls system and uses the same options except that `approved_domains`
|
|
(in favor of the domains in the scope of the module).
|
|
|
|
Example config:
|
|
|
|
```yml
|
|
tls:
|
|
modules:
|
|
- name: acme
|
|
domains:
|
|
- example.com
|
|
- example.net
|
|
email: 'joe.shmoe@example.com'
|
|
server: 'https://acme-staging.api.letsencrypt.org/directory'
|
|
challenge_type: 'http-01'
|
|
```
|
|
|
|
### tls.proxy
|
|
|
|
The proxy module routes the traffic based on the ServerName Indication (SNI) **without decrypting** it.
|
|
|
|
It has the following options:
|
|
|
|
```
|
|
address The hostname (or IP) and port of the system or application that should receive the traffic
|
|
```
|
|
|
|
Example config:
|
|
|
|
```yml
|
|
tls:
|
|
modules:
|
|
- name: proxy
|
|
domains:
|
|
- example.com
|
|
address: '127.0.0.1:5443'
|
|
```
|
|
|
|
### 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
|
|
|
|
```yml
|
|
tcp:
|
|
bind:
|
|
- 22
|
|
- 80
|
|
- 443
|
|
modules:
|
|
- name: forward
|
|
ports:
|
|
- 22
|
|
address: '127.0.0.1:2222'
|
|
```
|
|
|
|
### tcp.forward
|
|
|
|
The forward module routes traffic based on port number **without decrypting** it.
|
|
|
|
It has the following options:
|
|
|
|
```
|
|
ports A numeric array of source ports
|
|
ex: 22
|
|
|
|
address The destination hostname and port
|
|
ex: 127.0.0.1:2222
|
|
```
|
|
|
|
Example Config
|
|
|
|
```yml
|
|
tcp:
|
|
bind:
|
|
- 22
|
|
- 80
|
|
- 443
|
|
modules:
|
|
- name: forward
|
|
ports:
|
|
- 22
|
|
address: '127.0.0.1:2222'
|
|
```
|
|
|
|
|
|
|
|
### 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:
|
|
|
|
```yml
|
|
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:
|
|
|
|
```yml
|
|
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.
|
|
|
|
```yaml
|
|
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
|
|
```
|
|
|
|
### api
|
|
|
|
The API system is intended for use with Desktop and Mobile clients.
|
|
It must be accessed using one of the following domains as the Host header:
|
|
|
|
```
|
|
admin.invalid
|
|
localhost.admin.daplie.me
|
|
```
|
|
|
|
@tigerbot: How are the APIs used (in terms of URL, Method, Headers, etc)?
|
|
|
|
TODO
