can I run this on a headless server with no gpu?

No description provided.

No. It wasn't configured to be headless. There are other docker images that are built for this already. Is there something about this image you like that others don't offer? If not, I suggest checking out another project like this one...

[adrianog]

I want:
Ubuntu 22
xfce
no gpu required
rdp (x2go/vnc nice to have)
systemd as pid 1

[mscrnt]

Does this work for you?

[adrianog]

Yes.
What are the implications of running the container as "privileged" though? is it going to modify the host in any way. e.g. user creation?
Is it used for rw cgroup?
-v /sys/fs/cgroup:/sys/fs/cgroup:rw:
see moby/moby#42040
and long discussion, linked from there: moby/moby#42275

PS:
similar comment I made on another repo:
infrastlabs/docker-headless#12

[mscrnt]

Running in privileged mode is a little heavy handed. Let me see if I can work out another way that isn't so intrusive... It can definitely modify the host.

hey btw, I'm running the headless container without a gpu card, thanks.

I've tried to get snap running in the container but it's always failing after installing an app it cannot find the file to execute it?
snap list just hangs.

Did you get snap to work?

PS: tried to reboot the container and it doesn't work, looking at docker logs I see:
Failed to attach 1 to compat systemd cgroup /docker/7a16c64022374e09a94363996519ca50c4008fca1207e5456aac259c038e0f8e/init.scope: No such file or directory

I'll have to investigate this a bit more. I might have some time this week to dig back into this project.

[mscrnt]

@adrianog Sorry, it's been a long week.

I think I got this working. I've pushed the changes to the headless branch. Go ahead and give it a try and let me know if it works.

[mscrnt]

Main can now be run headless or with GPU support. I've also preinstalled snap. I did not include rdp or x2go in this image, but I think ssh and vnc should be sufficient.

[adrianog]

could we possible have rdp? it's a superior experience all around.
Thank you by the way, I'll be testing it as soon as rdp is in.

[adrianog]

Would it be possible also to have a different tag to support this branch of xrdp? https://archive.is/m5uz3
Seems to boost performance quite a lot.

[mscrnt]

I'm having some trouble on my end getting this to work correctly again. I'll be spending a good amount of time this week troubleshooting. I'll let you know when I make progress with this. Thank you for you patience.
