Hello Benoit,
I'm currently trying to create a Docker image based on Ubuntu 20.10LTS + Gambas Daily packages.
The goal is to run into a Docker a Gambas Web application build with gb.web.gui
The creation of the Docker image is simple but I'm facing a big bug when running the Web App:
-> The Web App in Gambas start by consumming all the memory of my PC and it is killed by the system due to full memory consumption.
Can you help me on that because it could be very cool if it work into a Docker Image ?
Procedure to reproduce the issue:
1 - Extract the archive file to build the Docker Image
2 - Open a terminal and move into the directory created
-> cd <path of dir>/Docker_image/
-> app/
-> WebUI.gambas
-> config/
-> docker_command.txt
-> Dockerfile
3 - Build the Docker Image
-> Dockerfile
