# Sentinel DataSource Etcd
|
||
|
|
|
||
|
|
Sentinel DataSource Etcd provides integration with etcd so that etcd
|
||
|
|
can be the dynamic rule data source of Sentinel. The data source uses push model (watcher).
|
||
|
|
|
||
|
|
To use Sentinel DataSource Etcd, you should add the following dependency:
|
||
|
|
|
||
|
|
```xml
|
||
|
|
<dependency>
|
||
|
|
<groupId>com.alibaba.csp</groupId>
|
||
|
|
<artifactId>sentinel-datasource-etcd</artifactId>
|
||
|
|
<version>x.y.z</version>
|
||
|
|
</dependency>
|
||
|
|
```
|
||
|
|
|
||
|
|
We could configure Etcd connection configuration by config file (for example `sentinel.properties`):
|
||
|
|
|
||
|
|
```
|
||
|
|
csp.sentinel.etcd.endpoints=http://ip1:port1,http://ip2:port2
|
||
|
|
csp.sentinel.etcd.user=your_user
|
||
|
|
csp.sentinel.etcd.password=your_password
|
||
|
|
csp.sentinel.etcd.charset=your_charset
|
||
|
|
csp.sentinel.etcd.auth.enable=true # if ture, then open user/password or ssl check
|
||
|
|
csp.sentinel.etcd.authority=authority # ssl
|
||
|
|
```
|
||
|
|
|
||
|
|
Or we could configure via JVM -D args or via `SentinelConfig.setConfig(key, value)`.
|
||
|
|
|
||
|
|
Then we can create an `EtcdDataSource` and register to rule managers. For instance:
|
||
|
|
|
||
|
|
```java
|
||
|
|
// `rule_key` is the rule config key
|
||
|
|
ReadableDataSource<String, List<FlowRule>> flowRuleEtcdDataSource = new EtcdDataSource<>(rule_key, (rule) -> JSON.parseArray(rule, FlowRule.class));
|
||
|
|
FlowRuleManager.register2Property(flowRuleEtcdDataSource.getProperty());
|
||
|
|
```
|
||
|
|
|
||
|
|
We've also provided an example: [sentinel-demo-etcd-datasource](https://github.com/alibaba/Sentinel/tree/master/sentinel-demo/sentinel-demo-etcd-datasource)
