Is there a way to install rancher desktop on a headless box? Say, to run integration tests? The question was moved to threads before anyone could see it

Not (yet) supported, but should be possible, depending on the OS.

E.g. on macOS you have to pre-configure to run without

sudo

, so you don't get a dialog querying for the password. Of course it also means that you only get port-forwarding, and not a separate IP address for the VM.

Thank you - I want to install in on Linux, like Ubuntu 18.04 and 20.04

The question is, how. Does installer on Linux require UI?

No, you can install rpm or deb package, and then run

rancher-desktop --no-modal-dialogs

You can specify kubernetes version (or disable it) as well

Nice, will try soon. Thank you @fast-garage-66093!

Oh, @fast-garage-66093 when I run it on Linux, do I run it as a regular user or root? I presume regular user, as it should be, and at some point I’ll have to provide root credentials. Can you elaborate on the process? To give you more context, I want to run a Linux Jenkins worker node, headless and unattended, and it might restart once in a while. Thanks!

You run as regular user; we should have a check in the latest version that prevents you from running as

root

Right thing to do, sure.

And on Linux there should be no prompt for the root credentials (because we don't yet support binding to external interfaces). Well, I'm not sure if we ask for credentials on Linux when you run with moby, to create the

/var/run/docker.sock

socket.

Can you please verify this yourself; I won't have time to test this until tomorrow

We also have to use docker and docker-compose for the backwards compatibility, thus we’ll have to have this socket

I’ll verify this and get back to you, hopefully find time for it this week

Thank you for your help!
