Hello Toradex Community
We want to switch from a Torizon-CMake Project to a Torizon-Qt6 Projekt. So we startet a C++ Qt QML Application project, because this is the only Qt6 Template-Project - dispide we only want to create a headless application.
im working with the following setup:
- Verdin AM62 1GB WB IT (V1.1A)
- Verdin Development Board (V1.1F)
- TorizonCore Version: 6.5.0+build.8
- Host-System Win 10 (WSL2)
We tried to throw all unrequired GUI stuff out to slim down the Docker-Image size. Here is an overview of the image sizes:
| cMake | Qt6 (default) | Qt6 (slimed down) | |
|---|---|---|---|
| Debug | 150MB | 750MB | 640MB |
| Release | 100MB | 680MB | 540MB |
I know the Qt stuff is heavy, but 600MB? … i doubt it.
Question:
- What else can I do to slim down the Image size?
- Is there an other base than
FROM --platform=linux/${IMAGE_ARCH} torizon/qt6-wayland${GPU}:${BASE_VERSION}which can be used?
In the Dockerfile we commented out the following:
- ARG GPU
- apt-get install of
imx-gpu-viv-wayland-devorlibglstuff - apt-get install of
qt6-waylandandqml6stuff
Here is my modified Dockerfile (same changes apply to Dockerfile.debug and Dockerfile.sdk):
