  1. Docker daemon running in Alpine container. Solved?

    I was able to setup Alpine 3.10 to run Docker daemon and run hello-world container in it. Here are the steps. create container based on alpine-3.10-default_20190626_amd64.tar.xz (disk of size 0.5GB is enough for this little test) under Options enable Features 'keyctl' and 'Nesting' start the...
  2. ARP table overflow - but only one neighbor

    Hi, i have some kind of legacy setup, which i created with Proxmox 5: I have a bunch of LXC containers which are privileged. Inside the LXC containers, i have installed a docker, and some docker containers. The networking of all this is managed by a VM with OPNsense. This worked fine with...
  3. Docker on promox recommendations

    As others on this forum we've been considering for a while migrating some installations to docker containers and also like other I would hope to be able to do it within the Proxmox setup. I was wondering if the new Proxmox 6 brings any updates or changes to this. As far as I understand Proxmox...
  4. Docker on LXC or VM?

    I'm considering running docker (and some docker containers) off of proxmox and wondered whether running docker inside an LXC or a VM would be better? I noticed from the following URL that it mentions that running docker in a VM would be better but gives no reason why this would be the case...
  5. Thinking of switching from vSphere

    We have a small vSphere cluster in our lab but we're increasingly using Docker. This however isn't ideal since we'd like a GUI managed solution which natively supports Docker (like Synology's DSM). Does Proxmox have Docker support in the web interface? I see mention of it in 5.3 but I can't...
  6. 5.3 and unprivileged containers: docker works, mount nfs does not

    I upgraded from 5.2 to 5.3 and am trying to re-deploy self service unprivileged containers where users create an LXC container and then can do whatever they need to do (mostly installing docker, mounting file systems etc) First I am disabling all the magic hacks that were required to run docker...
  7. 5.3: Docker on LXC on ZFS

    Hi, I'm toying with running Docker inside a CentOS 7 LXC on a Proxmox whose storage is ZFS. The container has: $ cat /etc/pve/lxc/209.conf ... features: nesting=1 ... and is a privileged container. For starters, the only storage driver that allows me to start the Docker service is vfs. ZFS...
  8. [SOLVED] LXC + docker, containerd cannot find /lib/modules/4.15.18-9-pve

    Hi all, Been stuck on this for quite some time and looking for some feedback. I'm running Proxmox 5.2 and I currently have 6 LXC Ubuntu 18.10 containers. 1 hosts rancher, 5 others host k8s worker/etcd/controller machines. I've been using the unsecure mode outlined here...
  9. Docker not working on Alpine Linux LXC

    Hello, I would like to manage docker work on an alpine LXC container. I can not launch any image. docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:402: container init caused \"rootfs_linux.go:58...
  10. Homelab newbie advice

    Hey, I'm planning to setup a server running proxmox, but before I do, I'd like some advice for how I should arrange my disks. Today I'm running a Proliant Gen8 Microserver with 4x2TB, 1x128GB SSD drives using FreeNAS. But since I've been having trouble with FreeNAS and FreeBSD I'm looking two...
  11. What's Promox's response to: Package and Run Virtual Machines as Docker Containers

    Hi, I'm running a KVM with Docker inside. To be precise it's RancherOS promising a fast and lightweight OS for Docker. This works fine. However I asked myself why not running KVM inside Docker and came accross another product: RancherVM. In this article the advantages of this concept are...
  12. Making use of Local-LVM

    I have tried to understand how to make use of Local-LVM for LXC, but failing. Every time I attempt to create a new container, the only option is local as opposed to both local and local-lvm. Besides lxc, could I use local-lvm for a docker container? If so, how does one point a docker container...
  13. Ideal LVM setup?

    I forgot about the easy of use of Proxmox when I was looking to make my laptop into a virtual host. I was getting ready to install PM5 when I started to wonder about how to optimally setup my 2TB SATA drive.
  14. Possible to use btrfs inside container (not on host)?

    Hi there, I have been searching the internet for a couple of hours now and so far come up empty handed. I would like to create some containers and use Docker in them. I have this working by tweaking the /etc/pve/lxc/CTID.conf for the containers like so: lxc.aa_profile: unconfined...
  15. Sharing Necessary Hardware with LXC and VM

    30 year computer guy has spent weeks playing and reading the fine manual and still has virtualization questions for people a whole lot smarter than I am: Short version - I need help sharing hardware (details below): ZFS to containers, Optical drives to any guest os (VM or LXC), dogging down...
  16. Ran docker with namespace mapping in LXC encountered permission error

    Hi, Everyone I'm able to run docker container already, but recently, to avoid the security issue(http: docs.docker.com/engine/security/security/), I created a mapping user "dockremap" and add "--userns-remap=default" to the docker daemon, but now I'm experiencing permission issue, the error...
  17. Change Proxmox Default Container Configs?

    Hi there, is it possible to change the default LXC container configs so that they support docker? I can go into each container manually but I create a lot of containers so is it possible to do so? Currently I do this: cd /etc/pve/lxc nano 100.conf Then I add these lines: lxc.aa_profile...

  19. Docker and Proxmox side-by-side

    Hello, I've currenty setup another proxmox instance, which has some special needs. Since we have heterogenous systems (existing containers) and new docker(-compose) based solutions we try to get them all on one system. Therefore i installed a fresh proxmox system. The second step was to install...
  20. Creating VMs automatically - ansible, vagrant, API .. ?

    Is anyone on here provisioning and configuring VMs on Proxmox, in a programmatic way? I'm hoping to get something going with vagrant, ansible, etc, and/or perhaps the Proxmox API. I have several proxmox nodes in a cluster. Specifying a KVM template, hardware specifics (disk size, VLAN id etc)...
