Configuring system docker network causes kernel panic about os HOT 8 CLOSED

Debugging kernel panic are tricky. Afaik there is no better way that have big screen and boot with debug logging enabled. Still most of the time there is no useful stuff there.

However one thing which I wonder is that why you need change this? IIRC all containers which run in system-docker are using host networking anyway.

I managed to get debug message out from this by adding vga=ask kernel parameter in boot menu and selecting big enough resolution:

from os.

And looks that this is nothing new in 2.0.0 (and most likely even on Burmilla at all) but something which have been issue already in RancherOS.

from os.

OK, I understand.
Please close this ticket if you want to.

I think, there are several known bugs from RancherOS.
It may be helpful if we have some labels to categorize tickets.
("issues from RancherOS" or something like that.)

from os.

It is valid bug still but labeling these is good idea.

However one thing which I wonder is that what you actually are trying to achieve? Is problem just that default conflicts with some other network on your environment or do you really need bridge network for some reason?
My understanding is that none of system containers uses bridge network so it should be possible to set --bridge=none as workaround to https://burmillaos.org/docs/configuration/docker/#configuring-system-docker and if that works we can make it default on v2.0.

Ah, I don't have any actual issues around this.

Sometimes, auto-assigned bridge network address for user containers conflicts with my local network address.
So, I added this to configure the default address pool for the user-docker.

write_files:
- content: |
    {
      "default-address-pools":
      [
        { "base":"10.254.0.0/16", "size": 24 }
      ]
    }
  owner: root:root
  path: /etc/docker/daemon.json

I'm not sure if it's actually required or not, but I also tried to configure the address pool for the system-docker.

from os.

Is there any good way to capture boot log ?

FYI. Hust released v2.0.0-beta6 makes that a bit simpler. Just choose "Debug logging" option in boot menu.

from os.

Closing because v2.0.0-rc1 was released and in it system-docker bridge is disabled by default
