Cannot change user group id, restart again and again about xubuntu-vnc-novnc HOT 4 CLOSED

Hello,
I want to confirm the question. I'll check it. However, I cannot promise that it'll be this week, because I'm pretty busy elsewhere, but I'll try.

It's corrected in the release 20.06.
Thanks for the question, it has helped to fix an old bug. :)

This is how you can test that it's working.

First you can pull the lab variation of the image:

docker pull accetto/xubuntu-vnc-novnc:lab-ubuntu18.04.4

You can rename it, for example, to chenzilin/cubuntu-xfce4-dev-docker:v3.0:

docker tag accetto/xubuntu-vnc-novnc:lab-ubuntu18.04.4 chenzilin/cubuntu-xfce4-dev-docker:v3.0

Then you can run you script, which will start the container ubuntu-xfce4-dev-docker_chenzilin in the background:

$ cat ubuntu-xfce4-dev-docker_chenzilin.sh \
#!/bin/bash
docker run -d \
-p 14901:22 \
-p 15901:5901 \
-p 16901:6901 \
--user 1000:1000 \
--restart=always \
--name ubuntu-xfce4-dev-docker_chenzilin \
chenzilin/cubuntu-xfce4-dev-docker:v3.0

After checking that it's still running by using

docker ps -a

you can connect to it interactively

docker exec -it ubuntu-xfce4-dev-docker_chenzilin bash

and check the user and group IDs (note that the instance ID in the prompt will be different each time)

headless@456ef013eda3:~$ id
uid=1000(headless) gid=1000(headless) groups=1000(headless)
headless@456ef013eda3:~$ exit

There is also a simpler way, if you only want to check the user and group IDs. You can use a temporary container which will be automatically removed:

cat ubuntu-xfce4-dev-docker_chenzilin.sh \
#!/bin/bash
docker run -it \
--user 1000:1000 \
--rm \
--name just_test \
chenzilin/cubuntu-xfce4-dev-docker:v3.0 --skip id

You should get the following output:

Skip VNC startup
Executing command: 'id'
uid=1000(headless) gid=1000(headless) groups=1000(headless)
