Can someone point me to details of how an on-premise Octopus Deploy installation communicates with the Octopus license server? Is it one-directional from the on-premise server to the license server? What port(s) are required to be opened? What data is actually sent to the server?
Currently, licenses don’t communicate externally. There are some things Octopus Server requires a connection for, like Telemetry and syncing the Community Step Template library.
That’s not currently implemented yet. A version of Octopus with that in it will be released sometime in 2023. All current versions of Octopus won’t reach out for licensing purposes. I believe the port will be 443 when it does, though. That is what we use for all other external communication from the Octopus Server other than Tentacles/Workers. Don’t quote me on that please as it may change .
Please let me know if that helps or if you have other questions.
Thanks, Jeremy. Will there be communication from Octopus when this goes into effect? Our security team is looking for details on that communication to ensure that we won’t be violating any of the strict security policies we have in place.
