  1. [SOLVED] 'docker swarm init' broke vm networking

    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...

  3. LXC bind mounting NFS mount and docker containers

    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...

  7. latest update (2/8/21) broke docker in container?

    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...

    Docker under Proxmox

  10. Mock API in (docker) container?

    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...
  11. Can’t connect Docker container (Debian 10 LXC host) to external network

    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...

  14. [SOLVED] Docker breaks my Proxmox access

    I’m running Proxmox and a VM with a minimal debian OS. Everything worked fine until I installed docker and Portainer. Well, docker, Portainer and my containers work fine. But now my Proxmox is not accessable, not by GUI and not by SSH. I’ve read that docker could break the bridge as it uses...

  16. Docker containers don't resolve DNS

    Hi guys, Sorry to bother, but I got perhaps a fairly easy problem, but I can't seem to be able to solve it. I have 1 host with 3 VMs, all of them can reach Internet and resolve domain names, but Docker containers running on said VMs can't resolve DNS (ping google.com fails), but can reach...
  17. Docker with Cloud-Init Problems

    Hello, a few days ago we had the problem with several VMs(qemu) that after some time they don't connect to the internet anymore. After some searching, we found out that Docker changes the network configuration(initially set by cloud-init) by itself (the server doesn't have an IPv4 address...

    I've had this problem for a while here now, and I've turned the internet upside down trying to figure it out, but there is very, very little information out there about this specific warning.
