To install docker on the Fedora/Centos/RedHat/Oracle Linux OS and to grant it sudo privileges, follow these instructions:

# install docker
sudo dnf -y install dnf-plugins-core
sudo dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo
sudo dnf install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo systemctl enable docker.service

# make docker sudo
sudo groupadd docker
sudo usermod -aG docker $USER
sudo systemctl restart docker

Making docker part of the sudo group allows you to use docker commands like docker ps without needing to add sudo at the beginning.
