 The Triton repository agent that downloads model via dragonfly.
 
+
+
+# Example
+
+### 1.拉取镜像：
+
+    docker pull dragonflyoss/dragonfly-repository-agent:latest
+
+
+### 2.设置配置文件：
+2.1:在config.pbtxt远程模型仓库配置文件中添加以下字段：
+
+     model_repository_agents{
+
+      agents [
+          {
+               name: "dragonfly",
+          }
+      ] 
+    }
+
+2.2：在cloud_credential.json文件中添加认证信息:
+
+    {         
+     "s3": {
+       "": {
+       "secret_key":"",
+       "key_id":"",
+       "region": "",
+       "session_token":"",
+       "profile": ""
+        }
+      } //s3认证信息
+     "gs":{}
+     "as":{}  
+    }
+
+2.3：在dragonfly_config.json文件中添加认证信息:
+
+    {
+     "proxy": "http://127.0.0.1:65001", // Dragonfly 的地址
+     "header": {},
+     "filter": [
+     "X-Amz-Algorithm",
+     "X-Amz-Credential&X-Amz-Date",
+     "X-Amz-Expires",
+     "X-Amz-SignedHeaders",
+     "X-Amz-Signature"]
+    }
+
+### 3.执行命令：
+
+    sudo docker run  -it  --network host  -v {配置文件路径}:/home/triton/ -e TRITON_DRAGONFLY_CONFIG_PATH=/home/triton/dragonfly_config.json -e  TRITON_CLOUD_CREDENTIAL_PATH=/home/triton/cloud_credential.json  dragonflyoss/dragonfly-repository-agent  tritonserver --model-repository=s3://{ip}/models  --exit-on-error=false
+
+### 4.查看输出结果：
+
+      I1213 12:27:11.166347 1 server.cc:604]
