request help: failed to connect to the unix socket through docker

After solved the issue [https://github.com/apache/apisix-java-plugin-runner/issues/156]

I use docker-compose.yml which file is created by you to start apisix
```
sudo docker-compose -f ../ci/docker-compose.yml up -d

```

After that, apisix works. I can set routes as the quick-start.md.
But it not works after I configuring the Java plugin via
```
curl "http://127.0.0.1:9080/apisix/admin/routes/1" -H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1" -X PUT -d '
{
"methods": ["GET"],
"host": "example.com",
"uri": "/anything/*",
"plugins": {
"ext-plugin-pre-req": {
"conf": [
{
"name": "RewriteRequestDemoFilter",
"value": "{\"body\":\"hello\"}"
}
]
}
},
"upstream": {
"type": "roundrobin",
"nodes": {
"httpbin.org:80": 1
}
}
}'
```

I have checked the logs of the apisix docker
```
sudo docker logs -f ab0b81f8bdd5

```

```

There is the issue about the unix domain socket through docker and the host machine?

@tzssangglass Do you mind taking a look at this issue...
Thanks for your help in advance.
