Attempting to Start Prefect Server in Docker Container - docker

I'm relatively new to Docker and Prefect, and I'm trying to start Prefect Server in a docker container.
Here's my Dockerfile...
FROM docker:dind
WORKDIR /app
COPY . .
RUN apk update && \
apk add python3-dev libffi-dev openssl-dev gcc libc-dev make cargo && \
python3 -m ensurepip --upgrade && \
pip3 install docker-compose prefect && \
prefect backend server
CMD [ "sh", "script.sh" ]
and here's script.sh...
dockerd &
prefect server start
after an ungodly long build, docker seems to start fine when I run docker run --privileged=true --name prefect-server-container prefect-server-image, but then I get a socket timeout error...

any help is greatly appreciated!

Prefect provides its own base images on DockerHub under the name prefecthq. Try using the image provided here: https://hub.docker.com/r/prefecthq/server

Prefect uses docker-compose underneath and requires root privileges. Hence you need to add your user to docker group.
$sudo groupadd docker
$sudo usermod -aG docker $USER
$newgrp docker

I'm not sure what is causing this issue. My operating system is fedora 37 and I installed both docker and docker-compose with dnf. Does anyone know how I can fix this issue?
Is the Docker service running?
Try:
sudo systemctl start docker
Try adding this in the docker-compose.yml file:
build:
context: .
dockerfile: Dockerfile

I am trying to create a ".yml" for GitLab CI. I already have a "docker-compose.yml" which is executable in my local machine. However, when executing it in the Docker image, I encounter a few errors. These are the errors I get after executing "docker-comose up -d":

This is how my '.gitlab-ci.yml' file looks like:
image: docker
services:
- docker:dind
build:
script:
- apk add py-pip python3-dev libffi-dev openssl-dev gcc libc-dev make
- pip3 install --upgrade pip
- pip install docker-compose
- docker-compose up -d
I think one problem might be that docker-compose is not installed in your base image (which is docker).
Approach 1: Base image change
Your base image should be docker:dind
Install docker-compose by hand following the install guides in the docs
Approach 2: use compose base image
You could also try to use the official docker-compose docker image in order to get this working, but (at the time of writing) I do not know how this behaves with GitLab CI

Could you please share the docker-compose.yaml file ?
Please check the Odoo's docker-compose examples part:
