GitHub Action ignoring Docker Containers Entrypoint - docker

Question

I am working on a Flask application and setting up a GitHub pipeline. My Docker file has an entry point that runs a couple of commands to upgrade DB and start gunicorn.
This works perfectly fine while running locally but while deploying through GitHub action it just ignores the entry point and does not run those commands.
Hare is my Docker file -
FROM python:3.10-slim
WORKDIR /opt/app
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1
RUN pip install --upgrade pip
COPY ./requirements.txt /opt/app/requirements.txt
RUN chmod +x /opt/app/requirements.txt
RUN pip install -r requirements.txt
COPY . /opt/app/
RUN chmod +x /opt/app/docker-entrypoint.sh
ENTRYPOINT [ "/opt/app/docker-entrypoint.sh" ]
Docker entry point content
#! /bin/sh
echo "*********Upgrading database************"
flask db upgrade
echo "**************Statring gunicorn server***************"
gunicorn --bind 0.0.0.0:5000 wsgi:app
echo "************* started gunicorn server****************"
Here is my GitHub action -
name: CI
on:
push:
branches: [master]
jobs:
build_and_push:
runs-on: ubuntu-latest
steps:
- name: Checkout files
uses: actions/checkout#v2
deploy:
needs: build_and_push
runs-on: ubuntu-latest
steps:
- name: Checkout files
uses: actions/checkout#v2
- name: Deploy to Digital Ocean droplet via SSH action
uses: appleboy/ssh-action#v0.1.3
with:
host: ${{ secrets.HOST }}
username: ${{ secrets.USERNAME }}
key: ${{ secrets.SSH_PRIVATE_KEY }}
port: 22
- name: Start containers
run: docker-compose up -d --build
- name: Check running containers
run: docker ps
I am very new to Dockerfiles, writing shell commands, and GitHub Actions, so please suggest if there is an any better approach.
Thanks in advance!

Instead of using ENTRYPOINT use CMD inside your dockerfile. Because Entrypoint can override but CMD can not override.
