How to Install Docker and Create, Use, or Delete Docker Images

In this video we will install docker on a Linux Debian 12 server, then we will create a simple app, build a docker image and run the app on the docker image and after all we remove the image and then uninstall docker from the server completely. The commands we will use for this task go following.
Update your package list:
sudo apt update
Install necessary packages:
sudo apt install apt-transport-https ca-certificates curl software-properties-common
Add Docker’s official GPG key:
curl -fsSL download.docke... | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
Set up the stable repository:
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] download.docke... $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list :: /dev/null
Note: KZbin doesn't allow brackets in the description. Replace :: in the command above with bracket. Watch the video for more info.
Update the package list again to include Docker's repository:
sudo apt update
Install Docker:
sudo apt install docker-ce docker-ce-cli containerd.io
Verify the installation:
sudo systemctl status docker
You should see Docker running. You can also verify by running:
sudo docker --version
(Optional) Allow your user to run Docker commands without sudo:
sudo usermod -aG docker $USER
Log out and log back in for the group membership to be re-evaluated.
