Can't connect to my Milvus db

[alikaz3mi]

Describe the bug:

While I am able to connect to my milvus db via python:

from pymilvus import connections
connections.connect(
  alias="default", 
  host='localhost', 
  port='19530'
)

I can't connect to milvus via attu application which is installed in my ubuntu 22.04

Steps to reproduce:
1.
2.
3.

Attu version:

2.3.10
Attu version:

[shanghaikid]

attu docker version?

[cnzackliu]

I have the same problem .

I can connected my milvus via golang, but attu can not.

if you are using attu docker version, make sure the milvus's address is accessible from attu's container.

MILVUS_URL=127.0.0.1:19530 this is not going to work, please change it to a real milvus ip.

I deploy the attu with docker-compose ，it cannot connected to db. Why?

[shanghaikid]

please make sure attu container can access your milvus server through your network.

did this method solve the issue @cnzackliu .

@shanghaikid can you be little specfic, i am using milvus on docker and attu also on docker...i am using localhost:15930 (what exactly is a real ip)

ok, let me explain, hope you can understand this.

1. You open attu from your browser, then type milvus address, lets say 10.10.10.10, click the connect button
2. the browser send a request -> attu server with the milvus address(10.10.10.10), which is the container
3. the attu server should be able to visit the milvus(10.10.10.10), but 10.10.10.10 just an ip address, the container has its own networking, if 10.10.10.10 is not a WAN address, it can not be visited from the container.

so all you need to do is confirm that the address you entering is accessible from the attu container inside.

I got the same issue, but if you are running is the same docker-compose.yml, start the service with docker compose up -d, it should work. it works for me.

This not work for me

by starting the milvus-standalon first, and then by command line start as follow

docker run -p 8000:3000 -e  -e MILVUS_URL=172.30.0.4:19530 zilliz/attu:latest

in which cannot connect to database.

This works for me

here is my docker-compose.yml
