### Issue description
I have created simple route and upstream configuration. as follows:
Created route:
{
"uri": "/order",
"name": "",
"host": "localhost",
"upstream_id": "1",
"status": 1
}
Created Upstream:
{
"nodes": [
{
"host": "localhost",
"port": 9181,
"weight": 1
}
],
"timeout": {
"connect": 6,
"read": 6,
"send": 6
},
"type": "roundrobin",
"scheme": "http",
"pass_host": "pass",
"name": "Upstream1"
}
Binding
curl "http://127.0.0.1:9080/apisix/admin/routes/365245490364678847" -H "X-API-KEY: <KEY>" -X PUT -d '
{
"uri": "/order",
"host": "localhost",
"upstream_id": "1"
}'
But, when I tried this curl:
I am getting following issue:

I guess the service proxied by the upstream service runs on the host, apisix runs in the container and uses bridge mode. The configuration of localhost for the apisix upstream service will cause the bridge (172.18.0.1) to connect to 127.0.0.1 timeout. The solution is to set'localhost' Change to'host.docker.internal'...
