X11docker: Try to run magicmirror

[lpt2007]

Hi,

Same as kodi I try to run magicmirror on x11docker.
https://magicmirror.builders/

The steps:
I used raspbian-lite from this link:
https://www.raspberrypi.org/downloads/raspbian/

I enabled ssh with:

sudo apt-get update
sudo systemctl enable ssh
sudo reboot

I update host system:
sudo apt-get upgrade -y

I installed docker:

curl -fsSL get.docker.com -o get-docker.sh && sh get-docker.sh
sudo usermod -aG docker pi

I Installed x11docker:

sudo apt-get install -y xdg-utils
wget https://raw.githubusercontent.com/mviereck/x11docker/master/x11docker -O /tmp/x11docker
sudo bash /tmp/x11docker --update
rm /tmp/x11docker

I create folders:

mkdir /home/pi/docker
mkdir /home/pi/docker/magicmirror

create and edit Dockerfile:
nano /home/pi/docker/magicmirror/Dockerfile

add this:

FROM raspbian/stretch
RUN apt-get update -y
RUN apt-get upgrade -y
RUN apt-get install -y curl
RUN bash -c "$(curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/$
WORKDIR "/home/pi/MagicMirror"
CMD npm start

build docker container:
sudo docker build -t magicmirror /home/pi/docker/magicmirror

then I run:
x11docker magicmirror

error:

xdpyinfo:  unable to open display ":0".
xwininfo: error: unable to open display ":0"

[mviereck]

Are you still able to run your kodi image?
Try to add --no-auth. If that works, there is some authentication issue.

[lpt2007]

Yes, kodi is working. Now I try same on other apps.

Do you know how can I run raspbian/stretch bash command line from container and then run commands from dockerfile manually?

[lpt2007]

What this error means?
x11docker ERROR: Did not find a possibility to provide a display

[mviereck]

x11docker ERROR: Did not find a possibility to provide a display

This means x11docker neither runs on X nor found an X server. Is Xorg installed?

[lpt2007]

In host system or container?

[mviereck]

In host system or container?

On host. x11docker provides X from host to containers.

[lpt2007]

On host. x11docker provides X from host to containers.
Ok, thanks.

Can you help me about magic mirror app?
https://magicmirror.builders/

My docker file:

command to buil container:
sudo docker build -t magicmirror /home/pi/docker/magicmirror

then I run:

I know that error mean the location of package.json is wrong but why, command under Dockerfile is
runing under ~/MagicMirror?

[mviereck]

RUN cd MagicMirror

That does not work. You cannot switch directories with the RUN command in a Dockerfile. The next RUN will be in / again.
You can set a working directory with WORKDIR.

RUN cd ~/

That does not make sense either. During build the commands are executed as root. ~ will be /root.
x11docker creates an unprivileged container user with its own home directory different from /root.

RUN git clone https://github.com/MichMich/MagicMirror
RUN cd MagicMirror
RUN npm install -g express

The npm command won't be executet in MagicMirror.

I can't help to set up a correct installation, please look at the magicmirror documentation instead. It seems they provide a ready-to-use docker image. Also they provide instructions for installation with prepared installer scripts instead of fiddeling with the repo itself.

[lpt2007]

That does not work. You cannot switch directories with the RUN command in a Dockerfile. The next RUN will be in / again

I didn't know that. Thanks.

It seems they provide a ready-to-use docker image.

Can I use docker ready image? How?

[mviereck]

Can I use docker ready image? How?

Looking at the example given on their github page:

docker run  -d \
    --publish 80:8080 \
    --restart always \
    --volume ~/magic_mirror/config:/opt/magic_mirror/config \
    --volume ~/magic_mirror/modules:/opt/magic_mirror/modules \
    --name magic_mirror \
    bastilimbach/docker-magicmirror

Pull the image with docker pull bastilimbach/docker-magicmirror
Run x11docker with x11docker -- --publish 80:8080 -- bastilimbach/docker-magicmirror

Does magicmirror have a GUI at all? If not, you can just use their provided docker command or add x11docker option --tty to run without X.

[lpt2007]

Does magicmirror have a GUI at all? If not, you can just use their provided docker command or add x11docker option --tty to run without X.

Yes it has a GUI.

On host if I run:
npm start
magic mirror starts in GUI mode
if I run it like this:
node serveronly
magic mirror starts in server only mode

[lpt2007]

Pull the image with docker pull bastilimbach/docker-magicmirror
Run x11docker with x11docker -- --publish 80:8080 -- bastilimbach/docker-magicmirror

error: can't open display. Probably because magicmirror container starts in severonly mode?

[lpt2007]

I try to run with --tty:
x11docker -- --tty --publish 80:8080 -- bastilimbach/docker-magicmirror

error:

x11docker ERROR: Got error message from docker daemon:

Error: Can't open display: :0

[mviereck]

--tty was meant run run without X and it should be placed before --. If you want X, don't use --tty.

Error: Can't open display: :0

As said above:

Try to add --no-auth. If that works, there is some authentication issue.

[lpt2007]

I try to run with --no-auth
x11docker --no-auth -- --publish 80:8080 -- bastilimbach/docker-magicmirror

error:
Error response from daemon: No such container: x11docker_X0_cc28c0_bastilimbach-docker-magicmirror

[mviereck]

No other messages? Please show the full output.

[lpt2007]

Maybe tag is not correct:
https://hub.docker.com/r/bastilimbach/docker-magicmirror/tags

I have raspberry arm cpu?

[mviereck]

Maybe tag is not correct:

Than try with tag raspberry.
Pull the image with docker pull bastilimbach/docker-magicmirror:raspberry
Run x11docker with x11docker -- --publish 80:8080 -- bastilimbach/docker-magicmirror:raspberry

[lpt2007]

I find this Dockerfile:
https://github.com/bastilimbach/docker-MagicMirror/tree/master/raspberry

and file docker-entrypoint.sh
https://github.com/bastilimbach/docker-MagicMirror/blob/master/docker-entrypoint.sh

Problem is magicmirror starts in server only mode:
CMD ["node serveronly"]

I must add additional lines in Docker file.

[mviereck]

Problem is magicmirror starts in server only mode:

You can set another image command after the image name:
x11docker -- --publish 80:8080 -- bastilimbach/docker-magicmirror:raspberry node

[lpt2007]

You can set another image command after the image name:
x11docker -- --publish 80:8080 -- bastilimbach/docker-magicmirror:raspberry node

I think magicmirror gui start command is:
npm start or from ssh: DISPLAY=:0 nohup npm start &

docs about manual instalation and start
https://github.com/MichMich/MagicMirror#manual-installation

[lpt2007]

I changed:

and run with this x11docker command:
x11docker magicmirror

CMD ["npm start"]

Use :
CMD ["npm","start"]
or:
CMD npm start

[lpt2007]

Use :
CMD ["npm","start"]
or:
CMD npm start

Same message as with CMD ["npm start"]

[mviereck]

Try
x11docker -- --publish 80:8080 -- bastilimbach/docker-magicmirror:raspberry npm start

[lpt2007]

I try with original:
CMD ["node serveronly"]

and

x11docker -- --publish 80:8080 -- bastilimbach/docker-magicmirror:raspberry npm start

Still same message.

[mviereck]

I had a look at the ENTRYPOINT script: https://github.com/bastilimbach/docker-MagicMirror/blob/master/docker-entrypoint.sh

It has a bug in the last line. Instead of $1 it should be $@ or exec $@.
As a workaround, try:
x11docker -- --publish 80:8080 -- bastilimbach/docker-magicmirror:raspberry "npm start"

Edit: Make an update of x11docker to release 5.4.1. The previous version 5.3.3 did not handle quotes correctly in image command.

[lpt2007]

It has a bug in the last line. Instead of $1 it should be $@ or exec $@

Thats it. I add $@ this.

Now I have error:

If it shows no error in browser but an empty white page, than the connection has succeeded. Ask the magicmirror developer or look at its documentation why you don't see content.

[lpt2007]

I think there missing X11 packages in container?
xinit, xorg, matchbox

There is link with howto install magicmirror gui on raspberry:

Howto I add them to Dockerfile correctly?

[lpt2007]

I added those files in Dockerfile:

I figured out the error occured when I try to run mm from ssh if I run directly on rpi consol it works?
Partial success:)

But I need to find solution to run mm from ssh:

I try like this:
ssh to my rpi and run commands:

export DISPLAY=:0
x11docker --user=root magicmirror

Error:

npm info lifecycle [email protected]~start: Failed to exec start script
npm ERR! code ELIFECYCLE

[mviereck]

Why do you set export DISPLAY=:0? If you run ssh -X, it should be set already. If not, check XAUTHORITY, too.

[lpt2007]

If I don't run export DISPLAY=:0 before I run x11docker --user=root magicmirror I get error:

x11docker ERROR: You are running x11docker over SSH without providing a display.
  Please run with 'ssh -X' or 'ssh -Y'.
  (If you insist, you can run with option '--xorg', but won't see the result.)

[lpt2007]

If I run with x11docker --user=root --xorg magicmirror' I get error:

[mviereck]

ssh -X should set DISPLAY and XAUTHORITY. Check them both and provide them to x11docker.

[lpt2007]

ssh -X should set DISPLAY and XAUTHORITY. Check them both and provide them to x11docker.
I never use ssh -X and XAUTHORITY. Please explain how?

[mviereck]

I never use ssh -X

I thought you would. It allows to show GUI applications locally whilst they are running on a remote server.

You want to access the pi with ssh, but run and show the GUI application on the pi without seeing the GUI? The X server runs on the pi?
Than check XAUTHORITY on your pi and provide both DISPLAY and XAUTHORITY to x11docker.

[lpt2007]

Than check XAUTHORITY on your pi and provide both DISPLAY and XAUTHORITY to x11docker.

How can I check DISPLAY and XAUTHORITY on my pi?

I try like this but I get no output:
XAUTHORITY :

ps -u $(id -u) -o pid= |
  xargs -I{} cat /proc/{}/environ 2>/dev/null |
  tr '\0' '\n' |
  grep -m1 '^XAUTHORITY='

DISPLAY :

ps -u $(id -u) -o pid= |
  xargs -I{} cat /proc/{}/environ 2>/dev/null |
  tr '\0' '\n' |
  grep -m1 '^DISPLAY='

[mviereck]

How can I check DISPLAY and XAUTHORITY on my pi?

Start your pi with its X server.
echo $DISPLAY
echo $XAUTHORITY

[lpt2007]

I try to start xserver on my pi with command:
startx

I get black screen with cursor on it.

Then I connect through ssh:
When I run echo $DISPLAY or echo $XAUTHORITY I get nothing.

with xauth list command I get this:

raspberrypi/unix:0  MIT-MAGIC-COOKIE-1  0b8d582f6cdf6c3cffd6527411ff119f
raspberrypi:0  MIT-MAGIC-COOKIE-1  0b8d582f6cdf6c3cffd6527411ff119f

[lpt2007]

If I don't run statx first on my pi (I get black screen with cursor on it) I get nothing if I run xauth list command over ssh? Something missing on my host?

I am using raspbian lite image without desktop.
https://www.raspberrypi.org/downloads/raspbian/

I installed only those packages: xinit, xorg, matchbox

[lpt2007]

I have changed raspian lite to raspbian desktop image on host.

echo $DISPLAY
:0.0
echo $XAUTHORITY
/home/pi/.Xauthority

provide both DISPLAY and XAUTHORITY to x11docker.

Can you show me how?

[mviereck]

provide both DISPLAY and XAUTHORITY to x11docker.

Can you show me how?

export DISPLAY=:0
export XAUTHORITY=/home/pi/.Xauthority
x11docker [...]

[lpt2007]

export DISPLAY=:0
export XAUTHORITY=/home/pi/.Xauthority
x11docker [...]

Now is working, with one problem.

If I start raspbian on host only in console mode, magic mirror won't start. If I start raspbian on host with desktop magic mirror works ok. Why?

[eine]

If I start raspbian on host only in console mode, magic mirror won't start. If I start raspbian on host with desktop magic mirror works ok. Why?

x11docker uses an X server running on the host. If you don't have any, because you are in console mode, it cannot share it with the container. However, when you start in desktop mode, there is an X server running, so it can be shared.

You can probably use --xvfb to make magic mirror work in console mode. But, how are you going to see the content if you do so?

[lpt2007]

Why KODI works like that?

I start host in raspbian in consol mode. Then I connect to host trough ssh and just run:

export DISPLAY=:0
x11docker --homedir /its/docker/kodi --gpu -- --privileged -- kodi

And KODI start on host display.

[eine]

You can try comparing or providing the logs to know which option is being used and why it is failing.

[mviereck]

x11docker uses an X server running on the host. If you don't have any, because you are in console mode, it cannot share it with the container.

x11docker can start Xorg on itself if it runs on console. (Option --xorg).
However, if it works with kodi but not with magicmirror, than I have no idea why magicmirror fails.
As @1138-4EB says, you can provide x11docker.log on www.pastebin.com. Maybe magicmirror gives a hint in its error messages.

[eine]

x11docker can start Xorg on itself if it runs on console. (Option --xorg).

Indeed. However, there is a 'Lite' version of raspbian, which I don't know if includes xorg dependencies (see https://www.raspberrypi.org/downloads/raspbian/). Since he/she provides so little info about the context, who knows whether this is the image being used in 'console mode'.

x11docker --user=root --xorg magicmirror

It seems you ran x11docker in an X session.
You got this warning and an explanation how to fix it:

x11docker WARNING: Your configuration seems not to allow to start
  a second core Xorg server from within X. Option --xorg will probably fail.
  (Per default, only root or console users are allowed to run an Xorg server).

  Possible solutions:
  1.) Install one of nested X servers 'Xephyr', 'Xnest' or 'nxagent'.
      For --gpu support: install 'weston' and 'Xwayland'.
  2.) Switch to console tty1...tty6 with <CTRL><ALT><F1>...<F6>
      and start x11docker there.
  3.) Run x11docker as root.
  4.) Edit file '/etc/X11/Xwrapper.config' and replace line:
          allowed_users=console
      with lines
          allowed_users=anybody
          needs_root_rights=yes
      If the file does not exist already, you can create it.
      On Ubuntu 16.04 and debian 9 you need package xserver-xorg-legacy.

x11docker --user=root magicmirror

It seems you ran x11docker in an X session.

So npm ERR! code ELIFECYCLE.

We already had this error message above. I am citing myself:

npm info lifecycle [email protected]~start: Failed to exec start script
npm ERR! code ELIFECYCLE

This looks quite specific to magicmirror. Ask the developer what it means.

So, please find out what this error message means.

I also found:

xhost: unable to open display ":0"

Probably you set DISPLAY, but did not set XAUTHORITY. We already talked about that above.

@lpt2007 Please carefully read the terminal messages and the answers you already got. I am glad to help, but please be aware that it costs my free time and it is a bit frustrating if you don't do this basic work yourself.

I also found:

xhost: unable to open display ":0"

Probably you set DISPLAY, but did not set XAUTHORITY. We already talked about that above.

Before I run: x11docker --user=root magicmirror
I always run this:

export DISPLAY=:0
export XAUTHORITY=/home/pi/.Xauthority

I get errors xhost: unable to open display ":0" and npm ERR! code ELIFECYCLE only if I start raspbian on host in console mode. If X is running on host mm starts ok, no errors. I already explained here:

export DISPLAY=:0
export XAUTHORITY=/home/pi/.Xauthority
x11docker [...]

Now is working, with one problem.

If I start raspbian on host only in console mode, magic mirror won't start. If I start raspbian on host with desktop magic mirror works ok. Why?

[mviereck]

I get errors xhost: unable to open display ":0" and npm ERR! code ELIFECYCLE only if I start raspbian on host in console mode.

If you run on console, than you have no X server running. Than you must not set DISPLAY and XAUTHORITY because they suggest an X server would run.

[lpt2007]

Success:) I added sudo and privileged to command and mm starts ok.
sudo x11docker --user=root --xorg -- --privileged -- magicmirror

thx for time and patience :)
