# Reveal Server
## Installation
Install dependent packages with npm:
```
npm i
```
Or build a Docker image:
```
docker build -t reveal-serve .
```
## Usage
Run on your server. Specify a secret with the `s` option. Create a webhook that fires on the "push" event.
Ensure that your repo has a "website" configured. The last component of this path will be used on the server.
## Docker
There are some environment variables that can be used to configure the server:
* *RV_PREFIXES*: A comma-separated list of acceptable prefixes. For example, to allow GitHub, set `RV_PREFIXES=https://github.com`, or to enable only your repo set `RV_PREFIXES=https://github.com/username/`. If a prefix does not match, it will not be loaded.
* *RV_SECRET*: The contents of a secret that is shipped as part of the webhook.
* *RV_LISTEN_PORT*: The port number to listen to. Defaults to `9119`.
* *RV_LISTEN_ADDR*: The local address to listen to. Defaults to `0.0.0.0`
* *RV_ROOT*: The root where all repos will go to.
An example invocation would be:
```
mkdir repo-root && chown 1000 repo-root
docker run \
-d \
--restart unless-stopped \
--log-opt max-size=10m \
--name=reveal-serve \
-p 9119:80 \
-e RV_PREFIXES=https://github.com/example \
-e RV_SECRET=rvsecretkey \
-e RV_ROOT=/data \
-v $(pwd)/repo-root:/data \
reveal-serve
```
