How to create a service for Fedora/RHEL (systemd)
A common task for Linux administrators is to create a background task that must be executed in the background. The most popular service manager in the Linux world is the systemd. This is an example of how to create a new service and use it.
If you want to learn more about the systemd, I recommend this video made by "DJ Ware":
Requirements

Create the background service file
[Unit]
Description=my-service nginx example
# You may want to start after your network is ready
After=network-online.target
Wants=network-online.target
[Service]
ExecStart=/usr/bin/env docker run --name nginx --rm -p 8080:80 docker.io/nginx:alpine
Restart=Always
PIDFile=/tmp/my_service_pid
[Install]
WantedBy=network-online.target# Create the service file
vim /etc/systemd/system/my-service.service
# (if you change an existent file, you must reload the daemon config)
# Reload daemon config
systemctl daemon-reload
# Enable
systemctl enable my-service.service

systemctl start my-service.service
