## Manage services on YARN via REST API
|
||||
Below steps walk you through deploying services on YARN via REST API.
|
||||
Refer to [API doc](YarnServiceAPI.md) for the detailed API specificatiosn.
|
||||
### Start API-Server for deploying services on YARN
|
||||
API server is the service that sits in front of YARN ResourceManager and lets users submit their API specs via HTTP.
|
||||
|
||||
YARN API Server REST API can be activated in two modes: embedded or standalone.
|
||||
|
||||
### Start Embedded API-Server as part of ResourceManager
|
||||
For running inside ResourceManager, add this property to `yarn-site.xml` and restart ResourceManager.
|
||||
|
||||
```
|
||||
<property>
|
||||
<description>
|
||||
Enable services rest api on ResourceManager.
|
||||
</description>
|
||||
<name>yarn.webapp.api-service.enable</name>
|
||||
<value>true</value>
|
||||
</property>
|
||||
```
|
||||
|
||||
Services can be deployed on YARN through the ResourceManager web endpoint.
|
||||
|
||||
### Start Standalone API-Server for deploying services on YARN
|
||||
API server is the service that sits in front of YARN ResourceManager and lets users submit their service specs via HTTP.
|
||||
```
|
||||
yarn --daemon start apiserver
|
||||
```
|
||||
The above command starts the API Server on the localhost at port 9191 by default.
|
||||
|
||||
Refer to [API doc](YarnServiceAPI.md) for the detailed API specificatiosn.
|
||||
|
||||
### Deploy a service
|
||||
POST the aforementioned example service definition to the api-server endpoint:
|
||||
|
||||
POST the aforementioned example service definition to the ResourceManager api-server endpoint:
|
||||
```
|
||||
POST http://localhost:8088/ws/v1/services
|
||||
```
|
||||
|
||||
Or standalone API server:
|
||||
```
|
||||
POST http://localhost:9191/ws/v1/services
|
||||
```
