Hi Jayuda, Welcome to the community!

What host address did you fill in the studio form?

Also could you help ensure the version of nebula-graph and studio matched?

ref: https://docs.nebula-graph.io/2.6.2/nebula-studio/deploy-connect/st-ug-connect/

For now it should be nebula-graph(v2.6.2) and nebula-studio(v3)

Thanks for fast respond Mr. @wey-gu
I has make sure nebula graph v2.62 and nebula studio v3

Here docker-compose.yaml

version: '3.4'

Aha, you could try with my side project: https://github.com/wey-gu/nebula-up , after you docker-compose down your existing ones, then run curl -fsSL nebula-up.siwei.io/install.sh | bash you will have studio + nebula ready to be used ;-), not in single compose though.

[Jayuda]

hello @wey-gu ,
I have try your project nebula-up with all new container, and now show error failed: failed to open connection, error: failed to open transport, error: dial tcp 0.0.0.0:9669: connect: connection refused

I have try with 127.0.0.1 and localhost also show that error. But i try directly with scrypt golang server ready and connected.

[wey-gu]

Dear @Jayuda ,
Thanks for trying that out!
The address should be your eth0's(or another name like ens0 of the first NIC) address with port 9669 instead of 127.0.0.1
Could you give that a try?

[wey-gu]

I have try with 127.0.0.1 and localhost also show that error. But i try directly with scrypt golang server ready and connected.

The reason 127.0.0.1 works from golang but not working from studio is that the studio will call this address from the nebula-http-gateway container(127.0.0.1 wont reach out to the host network namespace) while your golang server is from the host network namespace.

[Jayuda]

sorry mr. @wey-gu i check on log error at graphd show

Could not open the file: /sys/fs/cgroup/memory/memory.limit_in_bytes

any clue ?

curl -fsSL nebula-up.siwei.io/install.sh | bash

yes, work well.
But i dont take any answer about error memory limit - i just recreate everything and all work well.
Thanks mr @wey-gu

Answered in the compose issue, it's caused by vesoft-inc/nebula#3278 .

In nebula-up it's already fixed with the latest v2.6.2 image.
