# Simple Gateway
This gateway reduces the configuration to a minimum by removing features that will not be required when starting to use a gateway. I'm open to expanding upon functionality on request, please just open an issue.
Docker image available at [Docker Hub](https://hub.docker.com/r/idrinth/simple-gateway).
## Support
You can get support via discord at [Idrinth's Server](https://discord.gg/xHSF8CGPTh).
## Pre-Defined Routes
### GET /
The route provides a quick json overview over the gateway.
### HEAD /alive
This route is meant to allow for easy pull-based uptime checks. It returns a 204 Status Code on success.
### GET /open-api
This route aggregates the open-api definitions of registered services and displays a unified scheme for usage in postman for example.
## Configuration
Configuration from different sources will be merged, with ENVs overwriting file based route definitions.
### ENVs
Configuring via the environment requires setting up the following values:
- SERVICE_OPEN_API_MERGING will enable updating of the open-api document if set to `TRUE`
- SERVICE_OPEN_API_FREQUENCY defauls to 60000ms and sets the update frequency
- REQUIRED_COOKIE_NAME will set a cookie name to check for is restrict is set to cookie
- ROUTES_TARGET_ORIGIN will set an Access-Control-Allow-Origin header and defaults to *
- ROUTES_TARGET_METHODS will set the Access-Control-Allow-Methods header and filling it activates the CORS responses for all routes
- /ROUTE_[A-Z0-9_]+/i defines the request root, where requests from the gateway will be send
- /RESTRICT_[A-Z0-9_]+/i is optional and can be any of none(standard), api-key, cookie or authorization
- /OPEN_API_[A-Z0-9_]+/i defines a route to retrieve the service's open-api document from. It will default to {host}/open-api
### File (routes.idrinth.json)
This file contains a json object defining all routes, it will look similar to the following:
```json
{
"test": {
"target": "http://example.com",
"require": {
"api-key": false,
"cookie": false,
"authorization": false
},
"open-api": "http://example.com/open-api"
}
}
```
Anything besides the key(that defines the path the gateway will route) and the target are optional.
