`localhost` not being picked inside JupyterHub #25

Closed ka-sarthak closed 1 month ago

ka-sarthak commented 1 month ago

When making API calls in JupyterHub of the Oasis deployment, the nomad.config.client.url containing localhost keyword does not work. localhost needs to be replaced with the IP address for a successful API call.

This piece of code leads to an error append below.

from nomad.config import config
url = config.client.url
print(url)              ##  output: http://localhost/nomad-oasis/api

from nomad.client import ArchiveQuery
query = {
    "entry_id:any": ["Mg1VZFNJ-a9bkHDK3syj7MM21pFr"]
}
ArchiveQuery(query=query, required='*', url=url).download()[0]

However, replacing the URL with this resolves the issue:

url = config.client.url.replace('localhost', '172.19.0.1')

Perhaps, some config that connects the localhost with the IP address is not being picked. I also raised this issue previously here: https://gitlab.mpcdf.mpg.de/nomad-lab/nomad-FAIR/-/issues/1968
