Re: Feedback - Docker container creation for Gambas Web Application

[Linus <olivier.cruilles@xxxxxxxx>]

Hi Benoit,

I tried to build a minimal Dockerfile as you mentioned, to run a Gambas Web Application using the embedded Web server of Gambas but
unfortunately I occurred the same issue than in the past, memory leak at the execution of the Gambas Web Application into the Docker container.
This memory leak does not appears when I use a traditional Web server in frontal into the Docker Image.


Did I missed something regarding you explanations ?


Here is the related Dockerfile:


# syntax=docker/dockerfile:1
#
# Dockerfile for Gambas Web Application

FROM ubuntu:25.04

# set version label
ARG BUILD_DATE
ARG VERSION
ARG GAMBAS_VERSION
LABEL build_version="Triton Digital version:- ${VERSION} Build-date:- ${BUILD_DATE}"
LABEL maintainer="Olivier Cruilles"
