[lxc-users] Mount additional storage into unprivileged container
Hi, all! I am learning LXC features because we are going to implement it in our production environment. Could somebody explain me is there any well documented way to mount additional filesystems or (preferable) block devices into Unprivileged containers? is it supports live migration of container? I've read a lot of articles and man pages but unfortunatly this question is still unclear for me... Currently my config looks like: name: test-container profiles: - default config: raw.lxc: lxc.aa_profile=unconfined * security.privileged: "true"* volatile.base_image: a19c9ae2bd2e7bf99b0e2d31a0707cc534781a4eba47f44f172f486d2e01c96b volatile.eth0.hwaddr: 00:16:3e:87:d6:d9 volatile.last_state.idmap: '[]' devices: data: path: /datastorage source: /dev/sdf type: disk But when I try to change security.privileged to ‘false’ I lost an ability to write to /datastorage path inside container. Currently I’m using version 2.0.5 of LXC -- WBR, Andriy Tovstik ___ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users

As i've read in https://github.com/lxc/lxd/blob/master/doc/configuration.md there are two storage option can be mounted into container: disk and unix-block device. I played with the both ones. Lets talk about disk device. As you can see in my example i've used disk device with a block device as a source. I can change source option and set directory as a source. Anyway i recieve "permission denied" error when i try to access to this directory inside my container... Remember we talk about unprivileged container. Privileged container works fine. I have found a lot of topics about this problem, but i'm seeking for official, best practice soluiton. -- > With best regards, > Andrey Repin > Tuesday, November 8, 2016 14:25:33 > > Sorry for my terrible english... > ___ > lxc-users mailing list > lxc-users@lists.linuxcontainers.org > http://lists.linuxcontainers.org/listinfo/lxc-users -- WBR, Andriy Tovstik ___ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
[lxc-users] Feature request: raw lxc utilities output format and operations with multiplie containers?
Hi all! During LXD learning i encountered with lack of some features. The first one is "raw" output format of lxc list. Currently lxc list supports two formats: table and json. Unfortunately both formats are unusable for scripting. It is very difficult to pass to script output likes: # lxc list --format table -c n ++ |NAME| ++ | mysql-rep1 | ++ | mysql-rep2 | ++ | mysql-rep3 | ++ When i try to use json format i see that useful fields like container name are missing in output. May be it will be useful to implement feature like: # lxc list --format raw -c n --no-header mysql-rep1 mysql-rep2 mysql-rep3 The second feature looks useful is ability run commands on multiplie containers simultaneously. For example: # lxc exec web-node* -- apt update What do you think about it? -- WBR, Andriy Tovstik ___ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users

Re: [lxc-users] Feature request: raw lxc utilities output format and operations with multiplie containers?
Thanks, Stéphane, i'm very inattentive... Now it looks better. Additional output format seems to be more comfortable than additional tools. But it insignificantly. And what do you think about the second question about ability to run commands on multiplie containers simultaneously using regexps as container name ?

Re: [lxc-users] LXD cluster is unresponsible: all lxc related commands hangs
Hi I stopped lxd via systemctl, then ran 'killlall lxd' and started lxd again. Problem was fixed. сб, 18 авг. 2018 г. в 17:50, Stéphane Graber : > Hi, > > Your logs show multiple LXD processes running at the same time. > The latest revision of the stable snap (8393) should have a fix which > detects that and clean things up. > > Stéphane > > On Fri, Aug 17, 2018 at 10:46:29PM +0300, Andriy Tovstik wrote: > > Hi! > > > > Both lxd.log are empty :( > > > > ps output - in attachment > > > > пт, 17 авг. 2018 г. в 18:06, Stéphane Graber : > > > > > On Fri, Aug 17, 2018 at 05:56:24PM +0300, Andriy Tovstik wrote: > > > > Hi! > > > > > > > > пт, 17 авг. 2018 г. в 17:46, Stéphane Graber : > > > > > > > > > On Fri, Aug 17, 2018 at 01:20:42PM +0300, Andriy Tovstik wrote: > > > > > > Hi, all! > > > > > > > > > > > > Some time ago I installed a dual node LXD cluster.

[lxc-users] Different storage pool drivers for cluster members
Hi, all! I have two-node LXD cluster, based on lxd 3.9 from snap. Both nodes having local storage created over LVM. Now i'm going to join another node to the cluster. But new node storage pool use ZFS driver. Is it possible to use storage pools having same name but different driver across cluster nodes? -- WBR, Andriy Tovstik ___ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
