LSIO Discussion Container Support

Hello all.

RaspberryPi 4B running openmediavault 5 with docker 5:20.10.23~3-0~debian-buster.

Deployed the following container via docker-compose:

version: "2.1"
services:
  kasm:
    image: linuxserver/kasm:latest
    container_name: kasm
    privileged: true
    environment:
      - KASM_PORT=443
      - TZ=Europe/Madrid
    volumes:
      - /path/to/data:/opt
      - /path/to/profiles:/profiles
    ports:
      - 3000:3000
      - 443:443
    restart: unless-stopped

But got “Err_Empty Response” error at:

https://local_ip:3000

I have tried changing the default ports:

    environment:
      - KASM_PORT=4443
    ports:
      - 3001:3000
      - 4443:4443

But got the same error at

https://local_ip:3001.

What am I doing wrong?

Thanks in advance.

Same issue today for linuxserver/kasm:latest on ubuntu 22.04 host with docker 20.10.17

I have tried with the latest image published yesterday:

linuxserver/kasm-arm64v8-1.12.0

sha256 8e96bb9824182c46e77c37290b01b7640c6face440511b55fc01da7c3891bf42

And now I am getting “Err_Connection_Timed_out” instead of “Err_Empty_Response”.

I have tried to define a user inside the container (docker user, with r/w access to docker/kasm folder):

environment:
  - PUID=1002
  - PGID=991

But still cannot access the initial configuration site.

Thanks in advance.

Not sure if this can help:
I’m running KASM 1.11 without any error so far, but as soon as I try to launch a new container with the 1.12 image linuxserver/kasm:latest@sha256:d40885d85b6ee9fb106dc2be35ff421425aa13916bfd5b2f70729581f96aba9e it launches and keeps giving me this error nonstop until I stop the container myself.

/usr/local/bin/dockerd-entrypoint.sh: 148: modprobe: not found
WARN[0000] containerd config version `1` has been deprecated and will be removed in containerd v2.0, please switch to version `2`, see https://github.com/containerd/containerd/blob/main/docs/PLUGINS.md#version-header

 (exit status 4)

I get to the Wizard page but it won’t show anything, just the kasm logo and the " Docker still loading, please refresh for installer" line forever, no matter whether I launch an entirely new container with new folders, using the 1.11 folders or even by updating the 1.11 container with the 1.12 image. 1.12 simply won’t start while 1.11 works just fine.

More than happy to provide more info if needed.

Thanks!
