Hi Pavol,
thanks for the link, I did some testing with the out of the box setup
(removed root:1000:1) of ubuntu, created two containers and passed the
same host directory through to both of them, then I created the same
users in the same order on both containers:
root(1000)
neuer(1001)
zweiter(1002)
this seems to work, when I create files inside this folder on one
container as neuer, I can only read them as neuer on the other container
and vice versa.
I would assume, that as soon as I create the users in a different order,
zweiter might become 1001 and neuer 1002 and therefore files created by
neuer in one container would be seen as files created bei zweiter in the
other, right? On the host, all files are seens as 101001 or 101001 anyway.
I would go ahead and use this setup for my homeserver to store
media/backups and run a fileserver in one container and other tasks in
another, is this setup stable enough if I set it up as described above?
this is my lxc config, is there anything I should change?
disktest:
path: /testdisk
source: /home/me/testdisk
type: disk
kind regards,
John

Hi Tycho,
thank you for your fast response.
My id on the host is indeed 1000. I read your blog article and
then had
a look at /etc/subuid:
before:
"me@host:~$ cat /etc/subuid
lxd:100000:65536
root:100000:65536
me:165536:65536"
after:
"me@host:~$ cat /etc/subuid
lxd:100000:65536
root:100000:65536
me:165536:65536
root:1000:1"
root seems to be already set up, maybe this is due to lxd being
installed on ubuntu 16.04? It would be really helpful if you could
explain to me what the mapping defined in this file really does.
Does it
make a difference if I add your line, or use the one already
there? How
does this file use the numbers (100000 and 65536)? Does 1000:1 tell
ubuntu to map the id 1 to 1, if so, what does 100000:65536 mean? Add
65536 to the 100000? If there is a user called "me" in the conatainer,
does a line "me:1000:1" work as well?
I appreciate any help.
with kind regards,
John
P.S.:
I answered to the mailing list, is this the right way to do it, or
should I answer to you directly?

Hello,
I have a directory on my host system and want to
create several containers
with the same users inside. I would like to pass the
directory through to
each container and allow the users to write and read
on it. The network
connection should be done using macvlan.
The howtos I have read so far show how to set up lxd,
which works very
well on my 16.04 host. Starting a container works out
of the box as
unpriviliged user as well.
My questions:
Is it even possible to share one directory on the host
with several
container?
All the howtos I could find mention some commands,
that need to be
applied, but they do not tell me about the commands I
need to type in to
make it work:
"That means you can create a container with the
following configuration:
lxc.id_map = u 0 100000 65536
lxc.id_map = g 0 100000 65536"
There is a big list of possible options on github, but
where does it tell
how to apply them?
Does someone know a detailed howto, that
describes a similiar setup like
mine?
http://tycho.ws/blog/2016/12/uidmap.html
<http://tycho.ws/blog/2016/12/uidmap.html> is a blog post I
wrote a
while ago talking about how to set this up with your home
directory.
You can mimic the settings for whatever user map you want, though.
Cheers,
Tycho
Every time I read something, I feel like missing
something important,
because I could not find a coherent compendium of
possible options on how
to do something.
kind regards,
John
