Docker-compose failed to restart inside ubuntu image - docker

Question

Im trying to host web app inside docker container and for it i need docker-compose in docker. I installed docker-compose inside ubuntu image and that solution worked! (im running container with privileged mode)
Image file:
FROM ubuntu:20.04
RUN apt-get update && \
apt-get -qy full-upgrade && \
apt-get -qy install sudo && \
apt-get install -qy curl && \
apt-get install -qy nginx && \
apt-get install -qy ca-certificates curl gnupg lsb-release && \
mkdir -p /etc/apt/keyrings && \
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg && \
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null && \
apt-get update && \
apt-get install -qy docker-ce docker-ce-cli containerd.io && \
curl -L "https://github.com/docker/compose/releases/download/1.28.6/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose && \
chmod +x /usr/local/bin/docker-compose && \
rm /etc/nginx/sites-enabled/default
WORKDIR /home

ENTRYPOINT ["/entrypoint.sh"]
Entrypoint:
#!/bin/bash
sudo service docker start
sudo nginx -g daemon off;
sudo service nginx restart
cd /home/docker && sudo docker-compose up
All working fine after container creation, but if i want to restart container with docker restart or sudo docker restart it throws this error(its full container log):

[128] Failed to execute script docker-compose
Any suggestions? I really got stuck on that problem :(

Answer 1

Its working finally!! For everyone else solution was to shutdown docker inside docker before container shutdown.
Entrypoint:
#!/usr/bin/env bash
sudo service docker start
sudo service nginx restart
cd /home/docker && sudo docker-compose up -d
onContainerStop() {
echo "Container stopped, performing docker restart procedure..."
# shellcheck disable=SC2046
sudo docker stop $(docker ps -aq)
sudo service docker stop
sudo service nginx stop
}
trap 'onContainerStop' SIGTERM
while true; do :; done
