Hi,
I'm trying to rebuild a base image from Dockerfile.debian
It fails because of unknown commands: add-pkg, del-pkg, sed-patch and install-icon...
same for Dockerfile.alpine.

I must have missed something...
Thans for your comments

When using the clipboard and submitting a lot of data, a loop of JavaScript errors happen.

From a user perspective, the clipboard submit does't work and the interface doesn't seem to be responsive. A refresh of the page is needed.

I´m currently trying to base a JRiver Media Center 25 container off your image. It´s already kind of working, but when you click minimize you have no way to get it back, other than restarting the container.

If you´re interested I have made the repo public on my gitlab right now https://gitlab.shio.at/max/jrivermc25-docker

Would be glad for any suggestions on how to achieve this, or wether or not you had to deal with this before. It works fine with guis that use standard window decorations. They go away. But for this one it neigher will go fullscreen on start, nor will it remove the mimize actions.

I don´t really expect any help necessarily. But if you already know, I´d appreaciate it nevetheless. Otherwise, I´ll keep digging this weekend (or after) and report back if I happened to solve it eventually.

As other tools from jlesage, it should be great to change the port from the Environment Variables.
I am using Docker inside of Synology DSM and is hard to do some configuration unless are exposed as variables.
I am using more applications from jlesage and I can't use them at the same time due to having the same port 5800 (like jdownloader) unless mapping ports, which I would like to avoid (although I know is possible).

Hi,
So far I've been using the docker tags "jlesage/baseimage-gui:alpine-3.10" without the version number on the end, but with the new alpine-3.11 the available tags all have "v" "number" at the end. Just asking if that's your new standard going forward? No problem if so, I can update all my dockerfiles to comply with the new tags.
thanks

Hi,

I have been trying to use this amazing container to run GPU applications. So far I have not ben able to do so.
I created a new container (I addedd the recipies that creates this container https://gitlab.com/nvidia/samples/blob/master/opengl/ubuntu16.04/turbovnc-virtualgl/Dockerfile )
I have tried everything, and even when I am able to run virtualgl with no problem and that the NVIDIA drivers ar eproperly configured (you can run nvidia-smi inside the container) the container doesn't use the GPU.
I reviewed your code and tried to make sense of it but I can't find the missing link. Have you run any application GPU capable with this recipie?
It would be really nice to have something like that .

It would be great to enable the use of loading custom fonts when the image is stared. My thought is something like this:

• Load font files in a unique namespace in the config mountpoint: /config/baseimage/fonts
• Setup an environment variable that will trigger loading if enabled, e.g. ENABLE_CUSTOM_FONTS=1
• On container start, the startup script checks the environment variable, and runs a font cache update: fc-cache -f -v -y /config/baseimage/fonts

This would enable end user custom fonts to be install simply by placing them in the correct location, ensuring it is enabled and restarting the docker container.

Hi!! First of all thank you for this awesome image. I use it for various applications and it would be awesome if you can update it to Alpine 3.10 :)

Thank you!

a place to suggest new images apps ?! thanks !

I´m trying to rebuild the baseimage for debian9 (arm) and debian10 (amd64 & arm) also did debian9 amd64 now. SSL does not work for VNC. I´m getting this error somewhere in the logs

==========================================================================
*** No encryption library could be found. ***
A libvncserver/libvncclient built this way will not support SSL encryption.
To enable SSL install the necessary development packages (perhaps it is named
something like libssl-dev or gnutls-dev) and run configure again.

Are you getting the same error, or am I doing something wrong?

Hello,

I'm using your JDownloader docker container a while and I'm happy. Now I tried to implement my own container based on your baseimage to run MTPlayer, Java-File.

The dockerfile loads jlesage/baseimage-gui:alpine-3.9-glibc-v3.5.2, install openjdk11, download MTPlayer and try to start MTPlayer:

`
FROM jlesage/baseimage-gui:alpine-3.9-glibc-v3.5.2

ARG DOCKER_IMAGE_VERSION=unknown

ARG MTPLAYER_URL=https://www.p2tools.de/extra/download/MTPlayer-9.zip

WORKDIR /tmp

RUN \
    add-pkg --virtual build-dependencies curl p7zip && \
    curl -# -L -o MTPlayer-9.zip ${MTPLAYER_URL} && \
    7za x MTPlayer-9.zip && \
    del-pkg build-dependencies

RUN \
    apk --no-cache add openjdk11 --repository=http://dl-cdn.alpinelinux.org/alpine/edge/community
    
COPY rootfs/ /

WORKDIR /tmp/MTPlayer

ENV APP_NAME="MTPlayer" \
    S6_KILL_GRACETIME=8000

VOLUME ["/config"]
VOLUME ["/output"]`

I know there is a lot of optimization (e.g. volumes), but I tried first to run the app and after I will make it nice.

In rootfs there is a file called startapp.sh with the following lines:

#!/bin/sh
java -Djava.awt.headless=false -jar ./MTPlayer.jar "$@"

I build the image with docker build -t mtplayer . and the build-process-output looks fine. When I try to start the container with

docker run -it -p 5800:5800 mtplayer

I get the following error:

Any idea how I can solve this please?

I'm trying to use this brilliant image with VSCode Dev Container and I fail miserably. Seems to be some issue with the VSCode sleep command to keep workspace open and the startapp.sh functionality. As a workaround I have been trying to let this image sleep and wait for connection to x server over tcp by adding '-listen tcp -ac' to the Xvfb startup, and have my program connect from another container. However getting this working seems to be above my level of understanding :( Any ideas?

Enable dark mode of linux in order to get the QT dark mode, and apps like mkvcleaver, mkvtoolnix, handbrake could trigger automatically dark mode.

Hi,

I'm using docker-jdownloader-2, based on docker-baseimage-gui.

I have issue to see correct names of the packages / filenames in VNC.

The first package name is in Japanese (no clue what it there) and the second has some wired characters in the name (source: https://www.youtube.com/watch?v=rD-nLlXSSxs).

What is missing in the configuration in this case?

The link to "XDG Base Directory Specification" is https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html but that leads to a '404'. Maybe the new URL is https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html

I have tried alpine, debian and ubuntu, i always get this message.

My basic approach is this:
Inside the Dockerfile

1. I copy the .jar file to the /opt/nitro/ directory
2. Install java
3. Copy startapp.sh to /

Inside the startapp.sh:
/usr/bin/java -jar /opt/nitro/myapp.jar

A lot of hours have gone into this and I don't know what I could possibly do to make this work.
If you could assist me, that would be awesome.

Thanks!

Trying to run an app using jlesage/baseimage-gui:debian-10. Its trying to write to /dev/null. It doesn't seem to be able to create a temporary file. Any suggestions. I tried running the container under privileged mode that doesn't seem to help.

Hi,
I need to run WinScp on the container using wine. as for now WinScp is x86 based and can't be running
with .x64 wine.
Cheers

The documentation specifies the ports you can use to access the web interface and the VNC server for the container, but I do not see anything that references the Remote Presence Port is that the container uses when it connects to connect to iDRAC 6.

You can see this value when you log into the iDRAC admin console and navigate to System -> Console/Media -> Configuration.

I changed the Remote Presence Port on my iDRAC6 controller in my Dell R410 Server to port 4900. I forget why I did it - it was a long time ago. The default value is 5900 per Dell's documentation.

Since the Remote Presence Port value is not exposed in your Docker container, when you try to connect via the container, the connection fails.

I changed the Remote Presence Port in iDRAC6 from 4900 back to the default 5900, and I was able to connect using the Docker container!!! This is AWESOME!

Great job! Please update the docs to reflect this as it's pretty important.

Thank you for your good and easy to customize base image with a nice gui
I use your base image and customized it with running custom code now i have following problem
when i run more then 1 replicas on my vm in swarm mode
i can just access the latest created replica via http://hostdns:5800

i cannot use a port range in my docker compose file as its not allowed in swarm mode
currently my stack looks like that
version: '3' services: worker: image: vnc-docker:1.0 shm_size: 2g privileged: true volumes: - /home/username/firefox:/config:rw ports: - 5800:5800 deploy: mode: replicated replicas: 1 update_config: parallelism: 1 delay: 10s restart_policy: condition: any

i tried different things out, like creating a custom network and use it

something like
ports: - 5800-5900:5800
does not work
i just found out now that there is something like mcvlan, but i just couldn't figure out how to create a macvlan network and use it in my compose?

Is there any plan to release a Ubuntu 18.04 LTs release of this handy baseimage-gui?

Is there a way to enable clipboard at the image? I want to paste into the application and copy from the application running in the container

Hello,

is there any plan to create ARM64v8 images of this project?.

They are only amd64 as far as I've seen and it would be useful for all of us having Raspberry Pi 4 (or clusters of it).

Thank you!

Trying to create a Calibre docker based on this image, keep getting this error:

startapp just contains a call to start calibre from /opt/calibre/ . Any insight appreciated.

Hey, I want to run a wine application with this docker image. But when i start the container, it exits immediately.

This is my Dockerfile:

Do you know what im doing wrong here?
Thanks!

Hi,

I'm trying to correct an issue I've got using this image as a base for a piece of software called dvdisaster. I've managed to get all the build working but I'm struggling with the permissions to /dev/sr0. On the docker host my user with id 1000 is a member of the cdrom group which has rw on /dev/sr0 on my host but the app user inside the container isn't able to access sr0 from my host.

I have then docker exec'd into the container and done usermod -aG cdrom app and reloaded the app and it's then able to access /dev/sr0. I've tried adding the usermod to my Dockerfile but I think this user is made on container start.

Any tips?

Thanks,
b3vis

P.S I tried to look through your MakeMKV container to see how you've solved this on that image but was unable to see anything obvious

startapp.sh MUST Start with #!/bin/sh

#!/bin/sh
exec /usr/bin/xterm

Favicons are referenced using absolute paths (i.e. /images/icons/...)

All other resources in /opt/novnc/index.vnc are referenced using relative paths (i.e. js/..., css/..., etc).

Referencing resources via absolute paths breaks the application when it is running behind a reverse proxy using path based routing (i.e. http://server/appname/ --> http://realserver/).

This issue is affecting the 'jlesage/docker-handbrake' project, but as the script that installs the favicons exists in this project (i.e. /usr/local/bin/install_app_icon.sh), I am filing the issue here.

Arrow keys passed to the terminal emulator inside the docker image through NoVNC or VNC client does not work. The app shows ^[[A, ^[[B, ^[[C, or ^[[D instead.

Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval. It should work with any VNC viewer. Try it by running:

x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.

Hi! I've tried to run your example, replacing xterm with glxspeheres64 (the installed correctly from edge/testing repo of alpine) via x11docker.

Tested with a lot of different options but I got all the time this error:

/bin/sh: -c requires an argument

Do you have any idea why is this? Thanks.

Hello and thank-you for your work.
What do you think about add archlinux to your list of distribututions?

Thanks

The default port is set to 5800 for all your docker images and the default cannot be changed. For containers on my normal docker network this is fine since I can remap the ports in the compose file, but if I use a VPN docker network then all containers share the same network interface as the vpn client container.

For instance, the vpn client docker compose file would look something like this:
vpn_client:
image: dperson/openvpn-client
ports:
#ports for app containers' UI to be reachable from local network
#firefox
- "5801:5800"
#jdownloader
#- "5802:5800"
.... etc

and then your docker containers would have in their compose section:
network_mode: "service:vpn_client"

Since all your docker images share 5800 as the default port, I can't use more than one of them on my VPN docker network. Please add an environment variable to the base-image to change the default port number to allow cases like this.

I tried to build a baseimage-gui for ubuntu 14.04 to be able to use Ivideon with gui on my synology NAS.
(it does not work on ubuntu 16.04)

Not succeeding I went to try to rebuild the baseimage-gui:ubuntu-16.04-v3.3.5
I followed the full build process basimage ./build.sh ubuntu-16.04 then baseimage-gui idem

• in baseimage build curl curl no URL (idem for basimage-gui) (docker version 17.0.5.0-ce)
  solved transforming ARG xxx_URL in ENV xxx_URL
• bats not available (I don't know how to install it on Synoloy)
• basimage-16.0.4 finally built. It seems working I tried to build the xterm exemple. It stopped because of no display, but seems to work correctly

Then build of baseimage-gui

• I also had to to change a few ARG in ENV
• I have a lot of build errors
  • a few of these
    "invoke-rc.d: policy-rc.d denied execution of start."
  • and of these
    "npm WARN enoent ENOENT: no such file or directory, open '/tmp/package.json'
    npm WARN tmp No description
    npm WARN tmp No repository field.
    npm WARN tmp No README data
    npm WARN tmp No license field."

At the end an image is build but when I use it (xterm exemple) it doesn't work (docker build OK) and docker run start and immediately stop with the following logs

docker logs xterm

ifelse: fatal: unable to exec /etc/s6/init-no-catchall/init-stage1: Permission denied
ifelse: fatal: unable to exec /etc/s6/init-no-catchall/init-stage1: Permission denied

Could you help me debbug.
What is different in your building process ?

Hello! Thank you for your nice work!

Could you, please, extend it to ubuntu: focal? I tried to do it on my own, but I got confused.

Make the background of the GUI in dark mode (not talking about the apps inside, but just the white background in a black or dark grey background.)

It would be great to replace x11vnc and xvfb with TigerVNC. This would allow resizing of the remote desktop accordingly to resizing the browser window (perhaps best with disable option e.g. by setting the width and height explicitly).

I would like the help in the process if you want to.

Is there something that directly speaks against this idea? Perhaps you already tried and have good reasons not to use TigerVNC?

Best regards

Benedict

Hi,

It should be a good idea to enable this:
https://github.com/novnc/noVNC/blob/master/vnc.html#L234

My work firewall is autoclosing websockets every few minutes.

Thanks !

Hi @jlesage !

I have a problem building my rclonebrowser image, the application only runs on first execution, and since the restart of the container, I only get a black screen. Did you notice problems with Qt applications? Thank you!

Hey @jlesage I am using your base image for a build of mine. Dockerfile below. Basically, it launches an instance of Thunderbird, which gives me the accessibility of webmail and the features of a desktop client. As Thunderbird profiles are launched from home directories, I mapped /config/app to a host directory containing the profile/settings. To test, I launched the container, with xterm as the startapp, set the home env with HOME=/config/app, and then proceeded to successfully launch thunderbird with thunderbird. With the test being successful, the last step is then to set the home directory for the user app (uid 1000) to /config/app within the dockerfile: ENV HOME="/config/app"

FROM jlesage/baseimage-gui:debian-10
RUN apt update && \
  apt upgrade -y && \
  apt install -y thunderbird

#Debugging purposes
Run apt install htop xterm -y
COPY startapp.sh /startapp.sh
ENV APP_NAME="Thunderbird"
ENV HOME="/cofig/app/"

However, upon logging into xterm as user app, HOME remains empty:

Can you tell me how/why this ENV isn't sticking or is getting overwritten? Thanks!

PS Love your work. Keep it up!

Hello,

Thanks for these great containers.
Is it possible that you can update
libvncserver
x11vnc
novnc

These were forked in 2017 and I am pretty sure there are many improvements till now. It would be great if you could upgrade these.

Hi

Is there a way to run a full desktop , with this ?

Basically I have an app that calls a web browser for authentication purposes

Any help is appreciated

Thanks

Any hint?

By default, both ports 5800 and 5900 are exposed in the container. It would be fantastic to be able to add the option toggle the following port exposures:

• 5800 (VNC web GUI only)
• 5900 (VNC server only)
• 5800-5900 (both VNC web GUI, VNC server; current mode)

This would enable the selection of the preferred connection for an end user and minimize service exposure in the container.

I can run container fine and install & run chrome normally. But when I try to navigate to our LAN server (located in 192.168.0.1) connection is rejected. A NMAP scan from inside the the container shows dns is correctly result but that ip redirects to local instead of remote machine:

# nmap 192.168.0.1

It would be super useful for a image for this based against the nvidia docker images potentially to accelerate rendering if GPUs are available or as in my case in order to use CUDA to accelerate the program I am running.

This would potentially be extremely useful for people if they wanted to run things like Handbrake as it would enable accelerated transcoding using the nvidia runtime for docker.

At the moment I am tinkering with this to see if I can get it working, but you'd be a lot more familiar with your image!

I set up JRiver docker on a QNAP running QTS 4.4.3 vith a VNS set up for more security. If I use a web interface I get a JRiver screen but a red X at the top to the right of JRiver. When I look at the QNAP Container station it shows an app withthe directory/User I used for the config with JRiverMC26 under that when I expand it. When I look at the run informtion it appears to be taking a number of errors.

I'll send you the run info if you can tell me how to attach it. It's in a TBZ file type and it doesn't look like my PC will handle converting/expanding that.
