Notebook Server cannot communicate outside the container

StefanUseldinger — Thu, 25 Jan 2024 10:33:28 GMT

We installed and configured NBS on a Ubuntu 22.04.3 LTS (GNU/Linux 5.15.0-91-generic x86_64) and try to communicate with our Portal.

First, we received the common error "Temporary failure in name resolution" which was fixed by adding the dockerExtraHosts

But after that, we received a timeout. We tried:

from arcgis.gis import GIS gis = GIS(".../portal")

import requests res = requests.get('https://...')

and received:

ConnectionError: HTTPSConnectionPool(host='...', port=443): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7fece4dedd00>: Failed to establish a new connection: [Errno 110] Connection timed out'))

I saw that the docker containers being launched communicate via the bridge docker namespace/network. I connected myself to the container. Inside the container, curl requests failed, too. I checked iptables but did not see any blocking rules.

Do You have a clue how I can make NBS communicate with our Portal?

Hi, did you fix your issue now?

We had similar issue in ArcGIS Notebook Server 11.1 which sitting in AWS EC2 instance with Ubuntu 22.04.6.

After a few tests with ESRI support team and our internal Docker specialist and AWS support team, we found out the container is using bridge network and can only working with the FQDN which is accessible from public, or IP address in our case.

We also tried to run "docker run --net=host" command to launch a new ESRI notebook container, and the container working fine with curl requests for both internal and external urls. But we could not find a way in ArcGIS Notebook Server 11.1 to change the network for the docker container.

In my case, the software configuration management tool of my IT department ("Puppet") reset the firewall rules regularly that were set by docker when the deamon was started. Adding the specific docker rules to the tool config solved the problem and the bridge network communication started to work.
