Problem logging directly in a container from crosh

[Antoine Beaubien]

Hi,

   I have problems logging directly in a container from crosh:

crosh> vsh termina debian12
ERROR vsh: [vsh.cc(173)] Failed to launch vshd for termina:debian12: requested container does not exist: debian12
ERROR - ERROR: command failed

   But, I'm sure that my machine debian12 exists:

(termina) chronos@localhost ~ $ lxc list
+----------+---------+------+------+-----------+-----------+
|   NAME   |  STATE  | IPV4 | IPV6 |   TYPE    | SNAPSHOTS |
+----------+---------+------+------+-----------+-----------+
| debian12 | STOPPED |      |      | CONTAINER | 1         |
+----------+---------+------+------+-----------+-----------+
| kali24   | STOPPED |      |      | CONTAINER | 0         |
+----------+---------+------+------+-----------+-----------+
| ubuntu   | STOPPED |      |      | CONTAINER | 0         |
+----------+---------+------+------+-----------+-----------+

But if I go in termina, than do: 

lxc start debian12 and 

lxc exec debian12 -- bash, this works.

Regards, Antoine

Hi Antoine,

vsh relies on a vshd server running in the container, which is
normally launched by garcon, which itself is started by a systemd unit
(cros-garcon.service). garcon registers itself with the cicerone
service running on the host, which is how the host learns about the
available containers. If you want to use vsh with a custom container,
you might be able to replicate this configuration yourself, although
it is not officially supported.

Thanks for those very precise informations. Much appreciated.

It there somewhere I can find the documentation on how to setup the crostini-guest-tool on a new container?

I understand this is done automatically when ChromeOS is setuping penguin, the default Linux Debian 12 container, but is there somewhere this is documentated?

Also, which script is run when setting up the default container?

Can I find it here in this repo: github.com/lubuoren/cros-container-guest-tools ?

Regards, Antoine

Check on Reddit in the r/crostini wiki, they've documented alternative containers and the tooling with examples.

Thank you very much. I went a lot on the Reddit r/crostini, but I didn’t know there was a wiki. This is a perfect source for my questions.

Best Regards,
