Innkeeper

Innkeeper is a simple route management API for Skipper

When a new instance of Skipper (configured to fetch the routes from Innkeeper) is started, it will connect to Innkeeper, ask for all the routes and initialize its own data structures.

Then, at every x minutes will ask innkeeper for the modified routes and update its internal data structures.

Build Status

Getting started

First, create your application.conf file. One way to do it is by using the sample one:

cp src/main/resources/sample.application.conf src/main/resources/application.conf

Set the oauth.url with your OAuth provider url.

Innkeeper has three different OAuth scopes, configured in the application.conf file also. For more info, see the OAuth chapter.

Innkeeper requires a Postgres DB for operation. For local development, docker can be used to spawn a DB (see below the Postgres chapter).

To run Innkeeper, execute sbt run.

Running the tests

To run the unit test suite, run sbt test. To run the integration test suite, run sbt it:test.

Inserting a new route manually

curl -i -XPOST localhost:8080/routes -d '{
    "route": {
      "matcher": {
        "path_matcher": {
          "match": "/hello-*",
          "type": "REGEX"
        },
        "header_matchers": []
      },
      "filters": []
    },
    "activate_at": "2015-10-10T10:10:10",
    "description": "this is a route",
    "name": "THE_ROUTE"
    }' -H 'Content-Type: application/json' -H 'Authorization: oauth-token'

Getting all routes

curl http://localhost:8080/routes -H 'Authorization: oauth-token'

To see it streaming:

curl -i --limit-rate 3000 http://localhost:8080/routes -H 'Authorization: oauth-token'

Getting last modified routes

curl -i http://localhost:8080/updated-routes/2015-08-21T15:23:05.731 -H 'Authorization: oauth-token'

OAuth

A client can have different scopes when calling Innkeeper:

  • read -> the client is allowed to read the routes
  • writeFullPath -> the client is allowed to create only routes with a full path matcher
  • writeRegex -> the client with this scope is allowed to create routes with a regex matcher

Postgres

For localhost

CREATE ROLE innkeeper superuser login createdb;
ALTER ROLE innkeeper WITH PASSWORD 'innkeeper';

Postgres via docker

It is possible to simply start a docker container with a postgres ready for innkeeper by running:

$ docker run -e POSTGRES_PASSWORD=innkeeper -e POSTGRES_USER=innkeeper -p 5432:5432 postgres:9.4

For the tests, a different DB is used:

$ docker run -e POSTGRES_PASSWORD= -e POSTGRES_USER=innkeepertest -p 5432:5432 postgres:9.4

For users of boot2docker or docker-machine it is also necessary to create a port forwarding. Assuming the docker-machine is named default this can be achieved via:

$ VBoxManage controlvm "default" natpf1 "tcp-port5432,tcp,,5432,,5432"
$ VBoxManage controlvm "default" natpf1 "tcp-port5433,tcp,,5433,,5433"
