I have a VM (4 cores, 24GB ram) running Ubuntu 20.04 with pretty much only Docker installed. In the last period happened that it randomly die. The first time I got this problem was 15 days ago but all was fixed rebooting it but since today it keeps dying some time after its reboot. With "die"...

Hello, Using Proxmox VE for quite a while with VM and LXC on 5 physical servers. Too many times, we find ourselves creating a VM or an LXC container for a single Docker application. Mainly, we are creating an additional Linux server for the sole purpose of installing docker within it and...

Hello, I have some LXC containers with docker running inside them. Those work well with root-on-ext4, with the required changes in the .conf files. When I do the same on root-on-zfs, I get the following messages in the console: overlayfs: upper fs does not support RENAME_WHITEOUT. overlayfs...

Hallo! Ich möchte in meinem lxc Container ein CIFS-share und einen Docker Container laufen lassen. Leider ist es wohl so, dass man für CIFS privilegiert benötigt und für Docker unprivilegiert benötigt. Kann ich das irgendwie umgehen bzw. lösen? Error-Code: docker: Error response from daemon...

We would like to enbable nesting and keyctl for our LXC containers. Our customers demand these features so they can install and use Docker. There are (fairly old) posts suggesting this would be a security risk and we should be careful if we really want to do it as it could be possible for an...

Hi, Has anybody succeeded with running rootless (as ordinal user not root) Docker inside unprivileged LXC container? I followed this official guide: https://docs.docker.com/engine/security/rootless/. Installation failed with the following message:dockerd-rootless.sh[355]: [rootlesskit:parent]...

Firstly, I know now that my setup is not up to regs, but I'm not at a point right now where I can correct it until I'm back in some kind of working order. Explaining my issue starts with revealing my docker env is running on the host system and not in a vm. This 'hadn't' been an issue until...

I'm setting up a Proxmox VE server primarily for running an Ubuntu Server VM with several Docker services / containers for file-/media-hosting, but having the added flexibility of begin able to run additional VMs / LXC containers if required. The thought is to install Proxmox on two regular...

Hello, This weekend I finished configuring most of my personal server ( which is for development and fun so I don't care about security much ).. It was previously working as a nas server with Freenas and had rancher as docker host vm.. Although I wanted to have a full hypervisor with PCI-E...

Hello, yesterday I just upgraded packages and noticed that docker in my LXC containers stopped working. I found out that now /proc/sys is now mounted read-only inside the container, while previously it was mounted read-write. The errors I got in the container's syslog are: Feb 9 16:38:11...

Hey guys, Please let me introduce myself first since this is my first post here. I have been in the IT industry for 15 years, 99% of the time on Microsoft technologies and since last year i started to delve in the Open Source world (never too late man!) So, i've got a Proxmox lab, created an...

I have read numerous times that people request support for Docker in Proxmox so I use some time yesterday to find a solution. The basis for the solution was this on Youtube: https://www.youtube.com/watch?v=79KiCBNbsbg I have tested his solution and it works great - I have decommissioned my home...

I would like to be able to run some tests against the API for PVE (and PMG and PBS) but I don't want to have an entire instance of PVE installed. I know PVE needs its own kernel to work correctly (which cannot be guaranteed in a container) but I am not sure how much functionality is dependent on...

I’m getting mad in this situation so I decided to write here in the forum. I’m developing a simple application with .NET Core that connect a socket to a server (industrial protocol Modbus TCP) (port 502). I’ve made some tests with different configuration but more or less the result is always...
