Use the following command line to download the latest version of EventMesh:

sudo docker pull apache/eventmesh:latest

Use the following command to start the EventMesh container:

sudo docker run -d --name eventmesh -p 10000:10000 -p 10105:10105 -p 10205:10205 -p 10106:10106 -t apache/eventmesh:latest

Creating a topic is the first step in using EventMesh. You need to send an HTTP POST request to create a topic. Example Request

POST /eventmesh/topic/create HTTP/1.1  
Host: localhost:10105  
Content-Type: application/json  
  
{  
  "topic": "example-topic"  
}

After creating a topic, you can subscribe to it to receive messages. EventMesh provides two subscription methods: local subscription and remote subscription.

POST /eventmesh/subscribe/local HTTP/1.1  
Host: localhost:10105  
Content-Type: application/json  
{  
  "url": "http://localhost:8080/callback",  
  "consumerGroup": "example-consumer-group",  
  "topic": [  
    {  
      "topic": "example-topic",  
      "mode": "CLUSTERING",  
      "type": "SYNC"  
    }  
  ]  
}

EventMesh provides multiple message sending methods, including asynchronous sending, synchronous sending, and batch sending.

POST /eventmesh/publish HTTP/1.1  
Host: localhost:10105  
Content-Type: application/json    
eventmesh-message-topic: example-topic 
{  
  "content": "Hello, EventMesh!"  
}

When you no longer need to receive messages for a topic, you can unsubscribe.

POST /eventmesh/unsubscribe/local HTTP/1.1  
Host: localhost:10105  
Content-Type: application/json  
{  
  "url": "http://localhost:8080/callback",  
  "consumerGroup": "example-consumer-group",  
  "topics": ["example-topic"]  
}
