I have node docker application which is running on Azure app service but the same application is not working on Azure container apps. I'm not able to find the issue.please let me know what i'm missing here.

This is my Docker file

FROM node:alpine

# Need for privileged ports
RUN apk add --no-cache libcap

ARG DEVENV=dev

WORKDIR /var/app/UserService
COPY . .
COPY .env .env

RUN ls -la

RUN npm install
RUN npm install typescript -g
#RUN #apt-get install make
RUN apk add --no-cache make

RUN setcap 'cap_net_bind_service=+ep' /usr/local/bin/node
# Create user for App and give permissions to /app and /tmp folders
RUN addgroup -S appgroup && adduser -S appuser -G appgroup && chown -R appuser /app /tmp
USER appuser

EXPOSE 8000

CMD ["make", "run-migration","run"]

Based on the MICROSOFT DOCUMENTATION:-

---

Azure Container Apps can't run privileged containers. If your program attempts to run a process that requires root access, the application inside the container experiences a runtime error.
