Question: Docker installation - which IPs/domains must be unblocked on the internal firewall?

Forum - Installation
1

I want to install Eramba on a company-internal server. Per default connection to the internet is blocked - connections to external sites must be explicitly allowed / whitelisted.

I already found some adresses in the documentation and some by trial and error:

eramba.org
docker.com
docker.io
github.com
ghcr.io
  • ???

Is there a complete list of IP adresses/domains which have to be unblocked to be able to run the installation of dockerized Eramba ?

Best regards and many thanks for your help

Hello,

The Eramba application only needs a connection to support-v3.eramba.org.
GitHub is only needed when installing and/or updating the docker repository which happens from time to time but this is the docker layer, not eramba.

Hi Sam
thank you very much for your quick response!
The problem occurs when the firewall blocks connections required during the installation process…
Best regards

The Docker-installation (community-edition) finally worked after whitelisting these domains:

eramba.org
docker.com
docker.io
github.com
ghcr.io 
githubusercontent.com

Maybe one should put this info into the official dokumentation.
Best regards
Wolfgang
