# Annon API Gateway
Annon is a configurable API gateway that acts as a reverse proxy with a plugin system. Plugins are reducing boilerplate that must be done in each service, making overall development faster. Also it stores all requests, responses and key metrics, making it easy to debug your application. Inspired by [Kong](https://getkong.org/).
It's free. Source code is available on [GitHub](https://github.com/Nebo15/annon.api).
> "Annon" translates from the Sindarin word for 'Great Door or Gate'. Sindarin is one of the many languages spoken by the immortal Elves.
Annon consist of multiple main parts:
- [Annon API Gateway](https://github.com/Nebo15/annon.api).
- [Annon Dashboard](https://github.com/Nebo15/annon.web) - UI that allows to manage Annon settings, review and analyze Requests.
- [Annon Status Pages](https://github.com/Nebo15/annon.status.web) - UI that renders APIs status pages;
- [EView](https://hex.pm/packages/eview) - hex package that allows to receive and modify client responses from Elixir application to match [Nebo #15 API Manifest](http://docs.apimanifest.apiary.io/). So your back-ends will respond in a same way as Annon does.
- [Mithril](https://github.com/Nebo15/mithril.api) - authentication and role management service.
## Goals of the Project
- Provide single easy to use API management system for medium-to-large scale applications.
- Reduce amount of work needed in other components by orchestrating common functionalities.
- Monitoring - control response time and get answer "what happened" even in a single request perspective. Provide data for in-depth analysis.
- Authorization - set authentication and authorization requirements for each resource and reject requests that do not satisfy them.
- Improve platform scalability.
## General Features
### Caching and Performance
For performance issues Annon has build-in cache manager, it will load data from DB only once, all further work will be based on this cached data.
Whenever a single node receives request that changes cached data, it's responsible to notify all other nodes in cluster about change, and they should reload configurations from DB.
Whenever new node joins to a cluster, all other nodes should drop their cache, to resolve consistency issues.
This feature is done via [skycluster](https://github.com/Nebo15/skycluster) package. All gateway nodes is connected via Erlang distribution protocol.
It support different discovery strategies:
- `kubernetes` - selecting pods via Kubernetes API;
- `gossip` - multicast UDP gossip, using a configurable port/multicast address;
- `epmd` - using standart Erlang Port Mapper Daemon.
### Request ID's
When receiving request gateway will generate unique `request_id`. It is used to log request and this request is sent to all upstream, so whole back-ends that is affected by a request will create logs with same request id's.
Optionally, you can send `X-Request-ID` header with your own request id, but you need to make sure that its length not less than 20 characters. Also, if should be unique, or you will receive error response.
### Request Logger
Annon stores all requests and responses by their unique Request ID's in a Cassandra database. You use this information to query requests and get base analytics via [Requests API](#reference/requests/collection/get-all-requests).
API consumers may provide a custom request ID by sending `X-Request-ID: <request_id>` header. Thus, your Front-End and upstream back-ends can log information with a single unique ID.
Also, idempotency plug is relying on this logs to provide idempotency guarantees for requests with same `X-Idempotency-Key: <idempotency_key>` headers.
### Monitoring
To monitor services status we will use DogStatsD integration, that will receive following metrics:
- `request.count` (counter) - [API](#reference/apis) hit rate.
- `request.size` (gauge) - HTTP `Content-Length ` request size.
- `responses.count` (counter) - same as `request.count` but sent after request dispatch and additionally tagged with `http.status`.
- `latencies.{client,gateway,upstream}` (gauge) - total request latency for a API consumer, additionally tagged with `http.status`.
All metrics have tags: `http.host`, `http.port`, `http.method`, `api.name` and `api.id` (if matches any), `request.id`. This allows to set different aggregated views on counter data.
We recommend you to try [DataDog](https://www.datadoghq.com/) for collecting and displaying performance metrics. But this is not a hard constraint, instead you can use any StatsD collector.
### Requests Idempotency
Annon guarantees that replayed requests with same `X-Idempotency-Key: <key>` and same request will get permanent response. This is useful in a financial application, where you need good protection from duplicate user actions.
### Requests Tracing
Annon supports [OpenTracing](http://opentracing.io/) in Erlang via [Otter](https://github.com/Bluehouse-Technology/otter) library. This means that by implementing OpenTracing API in other services you can trace complete request impact for each of your services.
### Management UI
## Installation
Annon can be installed by compiling it from sources, but we recommend you to use our pre-build Docker containers:
- [Annon API Gateway](https://hub.docker.com/r/nebo15/annon_api/);
- [Annon Dashboard](https://hub.docker.com/r/nebo15/annon.web/);
- [Annon Status Pages](https://hub.docker.com/r/nebo15/annon.status.web/);
- [Cassandra](https://hub.docker.com/r/nebo15/alpine-cassandra/).
Our containers are based on Alpine Linux wich is a security-oriented, lightweight Linux distribution based on musl libc and busybox.
### Kubernetes
You can deploy it to Kubernetes using [example configs from Annon's Infra repo](https://github.com/Nebo15/annon.infra/blob/master/kubernetes).
### Docker Compose
For local environments we provide an [example Docker Compose configuration](https://github.com/Nebo15/annon.infra/tree/master/docker-compose). You can use this one-liner to deploy all Annon components on a local machine:
`curl -L http://bit.ly/annon_compose | bash`
## Source Code Documentation
Also there are auto-generated code documentation [available here](https://nebo15.github.io/annon.api/api-reference.html#content).
## License
See [LICENSE.md](https://github.com/Nebo15/annon.api/blob/master/LICENSE.md).
# Group APIs
API is a endpoint definition for any upstream back-end. They can be extended by Annons plugins.
#### Processing Order
Notice that even truough we trying to protect you from creating overllaping API configurations,
we can not guarantee that they always unique. API that was defined earlier will always have
higher priority, thus after creating overlapping API it won't work, but you won't break the one
that were working earlier.
### Pattern Matching
#### Wildcard Domains
In API request settings you can use `%` to match any substring in a request host. Eg: `%.example.com` will match `user1.example.com`.
#### API Path
In API request settings you can use `%` to match any substring in a request path. Eg: `/blog/%/comments` will match `/blog/my_post/comments` (and a `/blog/my_post/comments` since path is prefix for request).

# Group Plugins
## Proxy [/apis/{api_id}/plugins/proxy]
Proxy allows:
- Send HTTP requests from API to a `upstream`.
- Modify path and trim API-related part from it.
- Add headers to upstream request (for example, to authentificate on back-end behind gateway).
- Proxy `X-Request-ID` header, so all upstream back-ends can log request state with same UUID.
### Strip Request Path
You can set `strip_api_path` setting if you want to exclude API-related prefix from upstream request.
Request Path | Proxy Path | API Path | `strip_api_path` | Upstream Request
------------ | ---------- | -------- | ------- | --------
`/api` | `/proxy` | `/api` | `false` | `/proxy/api`
`/api/foo` | `/proxy` | `/api` | `false` | `/proxy/api/foo`
`/api` | `/` | `/api` | `false` | `/api`
`/api/foo` | `/` | `/api` | `false` | `/api/foo`
`/api` | `/proxy` | `/api` | `true` | `/proxy`
`/api/foo` | `/proxy` | `/api` | `true` | `/proxy/foo`
`/api` | `/` | `/api` | `true` | `/`
`/api/foo` | `/` | `/api` | `true` | `/foo`

## Authentication [/apis/{api_id}/plugins/auth]
This plugin authenticates API consumers by using a configured strategy.
Right now it supports two strategies:
- `jwt` - uses JSON Web Token to resolve consumer ID and scope.
- `oauth` - uses token from `Authorization: Bearer <token>` header and subsequent request to resolve consumer ID and scope via third-party provider.
### JWT Strategy
Decodes JWT tokens received from API Consumer and validates it signature by a configured secret key.
If token is invalid, appropriate error response will be send back to api consumer.
It requests `consumer_id` to be present in token itself, but Consumer `scope` can be resolved by:
1. Adding `scope` field in JWT token.
2. Subsequent request to a third-party provider.
**Warning!** JWT signature should be Base64 encoded. Some providers (for example, Auth0) already encode it for you.
#### Consumer Usage
Consumer should send `Authorization: Bearer <jwt_token>` header with his requests.
#### Subsequent requests
You can configure this strategy to resolve consumer scope by a subsequent request to a
third-party provider, in this case GET request will be send to `url_template`
with substituted `{consumer_id}`. Annon will expect `HTTP 200` response in following format:
```
{
"data": {
"user_id": "user-dsljsdflkdflj",
"details": {
"scope": "originator_loans:upload"
}
}
}
```
`$.data.user_id` will be mapped to Consumer ID.
`$.data.details.scope` will be mapped to Consumer Scope.
**OR**
```
{
"data": {
"consumer_id": "user-dsljsdflkdflj",
"consumer_scope": "originator_loans:upload"
}
}
```
If any other response is sent, Consumer will have no scopes but `X-Consumer-ID` header will be sent to upstream.
#### Auth0 Support
**Configuration**
To configure Annon copy-paste your `Client Secret` from `Clients` -> `Settings` to plugins `signature` configuration.
**Issuing a Token**
To receive an valid JWT with scopes token you must:
1. Set `app_metadata` for all your users, it should have AT LEAST one array with consumer ID:
```
{
"consumer_id": "my_consumer_id"
}
```
2. (Optional) If you prefer to receive scopes from Auth0 `app_metadata` should also have scopes array:
```
{
"consumer_id": "my_consumer_id",
"consumer_scope": "email:read email:send"
}
```
You can set default scopes in `Client` -> `Settings` -> `Advanced` -> `App Metadata`.
3. When authorizing consumers set correct scope to receive JWT token with `app_metadata`: `scope=openid app_metadata`.
4. Whenever you make requests to Annon, use `id_token` from Auth0 response (it's a JWT token that we need) in a `Authorization: Bearer <id_token>` header.
### oAuth Strategy
Recieves `access_token` from a `Authorization: Bearer <access_token>` header
and sends a subsequent request to resolve Consumer ID and scopes via third-party provider (eg. [Mithril](http://docs.mithril1.apiary.io/#)).
#### Consumer Usage
Consumer should send `Authorization: Bearer <access_token>` header with his requests.
#### Subsequent requests
GET request will be send to `url_template` with substituted `{access_token}`.
Annon will expect `HTTP 200` response in following formats:
```
{
"data": {
"user_id": "user-dsljsdflkdflj",
"details": {
"scope": "originator_loans:upload"
}
}
}
```
`$.data.user_id` will be mapped to Consumer ID.
`$.data.details.scope` will be mapped to Consumer Scope.
**OR**
```
{
"data": {
"consumer_id": "user-dsljsdflkdflj",
"consumer_scope": "originator_loans:upload"
}
}
```
If any other response is sent, Consumer will not be autheticated.
### Bind or Update Authentication Plugin [PUT]
+ Parameters
+ api_id: 1 (string, required) - API ID.
+ Request (application/json)
+ Attributes
+ plugin (`Plugin_Auth__Request`)
+ Response 200 (application/json)
+ Attributes (Response_OK)

## ACL [/apis/{api_id}/plugins/acl]
ACL allows to set scope to access certain subpaths of your API.
Once enabled it will restrict access to all subpaths of API, and you
need to allow access to them by whitelisting paths or path patterns.
It expects scope to be set in Auth plugin, if scope is not set,
API consumers will receive responses `unathorized` error.
Proxy configuration consist of pattern matches on request method and path:
```
rules: [
{methods: ["GET", "POST", "PUT", "DELETE"], path: ".*", scopes: ["request_api"]},
{methods: ["GET"], path: "^/profiles/me", scopes: ["read_profile"]},
{methods: ["POST", "PUT"], path: "^/profiles/me", scopes: ["update_profile"]},
{methods: ["DELETE"], path: "^/profiles/me", scopes: ["delete_profile"]}
]
```
Path is relative to API path, so you **don't need to specify API path prefix**!
**All rules is applied in a order they were defined.**
### Bind or Update ACL Plugin [PUT]
+ Parameters
+ api_id: 1 (string, required) - API ID.
+ Request (application/json)

```
rules: [
{methods: ["POST", "PUT"], path: ".*", schema: "{}"},
{methods: ["POST"], path: "^/profiles/me", schema: "{}"}
]
```
Path is relative to API path, so you **don't need to specify API path prefix**!

## Idempotency [/apis/{api_id}/plugins/idempotency]
Gateway supports idempotency for safely retrying POST requests without accidentally duplicating entity. Gateway always send back the same response for requests made with the same key.
However, you cannot use the same key with different request parameters.
To perform an idempotent request, send a POST requests with `X-Idempotency-Key: <idempotency_key>` header. `idempotency_key` can be any unique string up to 255 characters, we recommend to use UUIDs.
Enabling idempotency will increase response latency - Requests will be created synchronously to enshure read-after-write consistency.
