Hi!

I installed docker on a ubuntu server. I ran the docker file. Everything is up and running and I can access the webserver after I did some config so i can access it from http:/ip:8080

But... what exactly should I see when trying to access it... for me I get a blank page with:

QtWebGL - Waiting for connection..

Do I need to start something else.. I thought I would get to some config page and be able to run QT app from docker... what am I doing wrong this time ? 🗡️

I’ll write this down so I won’t forget later: "How to build and run the project from Docker":

Copy one of these directories with files:
- linux_gui_vnc
- linux_webgl
To build the project, you only need the contents of one of these directories, so there’s no need to pull the repository.
Navigate to the copied directory:
```
cd directory_name
```
Grant execution permissions to the build script:
```
chmod +x build.sh
```
Run the script:
```
./build.sh
```
After the build, you will have an image (you can check the list using docker image ls).
To run the project, execute the following command from the directory containing the docker-compose.yml file:
```
docker compose up -d
```

In case of any errors during the bui…

@nix155 could you help?

@cagnulein I'll try ))
@eskimos20 Could you provide a bit more detail—what specific file was launched, whether your host has Bluetooth, and so on?

I have a small Lenovo ThinkCentre .. a Intel 5 Core I5 with built in wifi, bluetooth 5.1 and so on.

I used this dockerfile: https://github.com/cagnulein/qdomyos-zwift/blob/master/docker/linux_webgl/Dockerfile

Seems updated and it worked well with install. Just needed to run it with:

sudo docker run -d -p 8080:8080 myimage

I can access both the container and the web interface but I get a blank page... just saying waiting for connection.

I think the problem might be that It cant access my Lenovos bluetooth.. or cant find it.

At least my bike is not connected since it should be a blue light.. but I can access the Wahoo kickr 0000 33 option from Zwift.. so it might be that it has started the program but it wont connect to the trainer. Maybe bluetooth is not exposed some how.

From the docker can we have the log?

Yes.. what is the location in the docker image to the log file ?

In both containers,
linux_gui_vnc
linux_webgl,
a two-stage build process is implemented. First, everything is compiled in the build container, and then the binary and required libraries are copied to the runtime container, which is then launched.

If you encounter any issues, I would recommend taking the linux_webgl directory, building the image from it (using build.sh), and running it (docker compose up -d) without the GUI by uncommenting the following line in docker-compose:

command: ["qdomyos-zwift", "-no-gui"]

After that, you can inspect the container logs:

docker logs qdomyos-zwift-webgl

For both directories, the process is the same: copy everything from the linux_webgl directory into a single directory, make the build.sh script executable (use chmod +x build.sh), and then build the image using build.sh. After the build, launch the image from the same directory (ensuring you have the docker-compose.yml file) with the command:

docker compose up -d

I tried to run just the QT that was in bin and found this:

Fri Dec 27 20:16:06 2024 1735330566764 Warning: Cannot find a running Bluez. Please check the Bluez installation.
Cannot find a running Bluez. Please check the Bluez installation.
Fri Dec 27 20:16:06 2024 1735330566764 Debug: devices/bluetooth.cpp void bluetooth::debug(const QString&) "no bluetooth dongle found!"
"no bluetooth dongle found!"

So it is not finding bluetooth :D

There might be issues with the GUI in both versions (although there shouldn’t be any on Ubuntu), but the GUI isn’t critical—everything can be configured via a config file, and you can view the logs in the console.

In any case, first, ensure everything works correctly without the GUI, and then add the GUI later if desired. I tested it on a laptop with Ubuntu/Fedora, and it worked.

Bluetooth not found ))
I’m not sure why you’d want a server on a laptop—just set up a regular workstation.

Its not a laptop... its a thinkcentre... its like a small Intel NUC.

I have some options.

Run it with gui (it will work) like a regular workstation
Run it without gui but I have not figured out how to set the config file, and what parameters should be used to add zwift click.

Are there any config examples ?

nix155 Dec 27, 2024

Yes, of course, and I mentioned this above.
Do you have experience working with Docker and Docker Compose?

I have only a little knowledge about docker so I will have to read and google some :D

@eskimos20 chatgpt for these tasks is perfect (claude.ai even better, it's the one that i'm using since 6 month)

All the settings for building the image include the Dockerfile, a build script (hehe) called build.sh, and for running, a docker-compose.yml file. The command to start it is docker compose up -d (from the directory containing the compose file).
For learning, I would recommend YouTube—it's a great resource and can be combined with a practice environment—and this is not a joke.

In case of any errors during the build (or while running), it’s usually enough to update the list of libraries—ChatGPT can help with that.

The first stage (build) can be used as an example for building on Linux (e.g., in a GitHub pipeline).

Added images to Docker Hub, you can download them with the following commands:

docker pull r155/qdomyos-zwift-gui-vnc
docker pull r155/qdomyos-zwift-webgl

To run them, you can use the corresponding docker-compose.yml files from the docker/... repository, updating the image name as follows:

image: r155/qdomyos-zwift-gui-vnc
image: r155/qdomyos-zwift-webgl

For local use, you can extract the binary from there. 😊

When the main repository is updated, the images should also be updated (though this is not guaranteed – it needs to be checked).

Moved from Docker Hub to GitHub, added a build for the Linux binary (with a 1-hour check interval for changes in the source repository).

I did docker pull r155/qdomyos-zwift-webgl
Changed the image to r155/qdomyos-zwift-webgl in .yml file
Changed values in .yml to: ["qdomyos-zwift", "-no-gui", "-zwift_play_emulator", "-no-log"]
Edited the restart parameter to "always"
Did a docker compose up -d

All good and working with zwift click! :)

Great work!

nix155 Jan 3, 2025

@eskimos20 - awesome!
Use the images from https://github.com/nix155?tab=packages.

For example:

docker pull ghcr.io/nix155/qdomyos-zwift-webgl:20250102-1413

or

docker pull ghcr.io/nix155/qdomyos-zwift-webgl:latest

I moved the image builds to GitHub, made them automatic upon updates to the main repository, and added date-based tags.
